66 Welcome to the <b>VirtualBox Main API documentation</b>. This documentation
67 describes the so-called <i>VirtualBox Main API</i> which comprises all public
68 COM interfaces and components provided by the VirtualBox server and by the
69 VirtualBox client library.
70
71 VirtualBox employs a client-server design, meaning that whenever any part of
72 VirtualBox is running -- be it the Qt GUI, the VBoxManage command-line
73 interface or any virtual machine --, a dedicated server process named
74 VBoxSVC runs in the background. This allows multiple processes working with
75 VirtualBox to cooperate without conflicts. These processes communicate to each
76 other using inter-process communication facilities provided by the COM
77 implementation of the host computer.
78
79 On Windows platforms, the VirtualBox Main API uses Microsoft COM, a native COM
80 implementation. On all other platforms, Mozilla XPCOM, an open-source COM
81 implementation, is used.
82
83 All the parts that a typical VirtualBox user interacts with (the Qt GUI,
84 the VBoxManage command-line interface and the VBoxVRDP server) are technically
85 front-ends to the Main API and only use the interfaces that are documented
86 in this Main API documentation. This ensures that, with any given release
87 version of VirtualBox, all capabilities of the product that could be useful
88 to an external client program are always exposed by way of this API.
89
90 The VirtualBox Main API (also called the <i>VirtualBox COM library</i>)
91 contains two public component classes:
92 <tt>%VirtualBox.VirtualBox</tt> and <tt>%VirtualBox.Session</tt>, which
93 implement IVirtualBox and ISession interfaces respectively. These two classes
94 are of supreme importance and will be needed in order for any front-end
95 program to do anything useful. It is recommended to read the documentation of
96 the mentioned interfaces first.
97
98 The <tt>%VirtualBox.VirtualBox</tt> class is a singleton. This means that
99 there can be only one object of this class on the local machine at any given
100 time. This object is a parent of many other objects in the VirtualBox COM
101 library and lives in the VBoxSVC process. In fact, when you create an instance
102 of the <tt>VirtualBox.VirtualBox</tt>, the COM subsystem checks if the VBoxSVC
103 process is already running, starts it if not, and returns you a reference to
104 the <tt>VirtualBox</tt> object created in this process. When the last reference
105 to this object is released, the VBoxSVC process ends (with a 5 second delay to
106 protect from too frequent restarts).
107
108 The <tt>%VirtualBox.Session</tt> class is a regular component. You can create
109 as many <tt>Session</tt> objects as you need but all of them will live in a
110 process which issues the object instantiation call. <tt>Session</tt> objects
111 represent virtual machine sessions which are used to configure virtual
112 machines and control their execution.

238 <desc>
239 This section describes all VirtualBox-specific COM result codes that may
240 be returned by methods of VirtualBox COM interfaces in addition to
241 standard COM result codes.
242
243 Note that along with the result code, every VirtualBox method returns
244 extended error information through the IVirtualBoxErrorInfo interface on
245 failure. This interface is a preferred way to present the error to the end
246 user because it contains a human readable description of the error. Raw
247 result codes, both standard and described in this section, are intended to
248 be used by programs to analyze the reason of a failure and select an
249 appropriate course of action without involving the end user (for example,
250 retry the operation later or make a different call).
251
252 The standard COM result codes that may originate from our methods include:
253
254 <table>
255 <tr><td>E_INVALIDARG</td>
256 <td>
257 Returned when the value of the method's argument is not within the range
258 of valid values. This should not be confused with situations when the
259 value is within the range but simply doesn't suit the current object
260 state and there is a possibility that it will be accepted later (in such
261 cases VirtualBox-specific codes are returned, for example,
262 <link to="VBOX_E_OBJECT_NOT_FOUND"/>).
263 </td>
264 </tr>
265 <tr><td>E_POINTER</td>
266 <td>
267 Returned if a memory pointer for the output argument is invalid (for
268 example, @c null). Note that when pointers representing input
269 arguments (such as strings) are invalid, E_INVALIDARG is returned.
270 </td>
271 </tr>
272 <tr><td>E_ACCESSDENIED</td>
273 <td>
274 Returned when the called object is not ready. Since the lifetime of a
275 public COM object cannot be fully controlled by the implementation,
276 VirtualBox maintains the readiness state for all objects it creates and
277 returns this code in response to any method call on the object that was
278 deactivated by VirtualBox and is not functioning any more.
279 </td>
280 </tr>
281 <tr><td>E_OUTOFMEMORY</td>
282 <td>
283 Returned when a memory allocation operation fails.
284 </td>
285 </tr>

506 Note that states to the right from PoweredOff, Aborted and Saved in the
507 above diagram are called <i>online VM states</i>. These states
508 represent the virtual machine which is being executed in a dedicated
509 process (usually with a GUI window attached to it where you can see the
510 activity of the virtual machine and interact with it). There are two
511 special pseudo-states, FirstOnline and LastOnline, that can be used in
512 relational expressions to detect if the given machine state is online or
513 not:
514
515 <pre>
516 if (machine.GetState() &gt;= MachineState_FirstOnline &amp;&amp;
517 machine.GetState() &lt;= MachineState_LastOnline)
518 {
519 ...the machine is being executed...
520 }
521 </pre>
522
523 When the virtual machine is in one of the online VM states (that is, being
524 executed), only a few machine settings can be modified. Methods working
525 with such settings contain an explicit note about that. An attempt to
526 change any oter setting or perform a modifying operation during this time
527 will result in the <link to="VBOX_E_INVALID_VM_STATE"/> error.
528
529 All online states except Running, Paused and Stuck are transitional: they
530 represent temporary conditions of the virtual machine that will last as
531 long as the operation that initiated such a condition.
532
533 The Stuck state is a special case. It means that execution of the machine
534 has reached the "Guru Meditation" condition. This condition indicates an
535 internal VMM (virtual machine manager) failure which may happen as a
536 result of either an unhandled low-level virtual hardware exception or one
537 of the recompiler exceptions (such as the <i>too-many-traps</i>
538 condition).
539
540 Note also that any online VM state may transit to the Aborted state. This
541 happens if the process that is executing the virtual machine terminates
542 unexpectedly (for example, crashes). Other than that, the Aborted state is
543 equivalent to PoweredOff.
544
545 There are also a few additional state diagrams that do not deal with
546 virtual machine execution and therefore are shown separately. The states
547 shown on these diagrams are called <i>offline VM states</i> (this includes
548 PoweredOff, Aborted and Saved too).
549
550 The first diagram shows what happens when a lengthy setup operation is
551 being executed (such as <link to="IMachine::attachDevice"/>).
552
553 <pre>
554 +----------------------------------(same state as before the call)------+
555 | |
556 +-&gt; PoweredOff --+ |
557 | | |
558 |-&gt; Aborted -----+--&gt;[lengthy VM configuration call] --&gt; SettingUp -----+
559 | |
560 +-&gt; Saved -------+
561 </pre>
562
563 The next two diagrams demonstrate the process of taking a snapshot of a
564 powered off virtual machine and performing one of the "discard..."
565 operations, respectively.
566
567 <pre>
568 +----------------------------------(same state as before the call)------+
569 | |
570 +-&gt; PoweredOff --+ |
571 | +--&gt;[takeSnapshot()] -------------------&gt; Saving ------+
572 +-&gt; Aborted -----+
573
574 +-&gt; PoweredOff --+
575 | |
576 | Aborted -----+--&gt;[restoreSnapshot() ]-------&gt; RestoringSnapshot -+
577 | | [deleteSnapshot() ]-------&gt; DeletingSnapshot --+
578 +-&gt; Saved -------+ |
579 | |
580 +---(Saved if restored from an online snapshot, PoweredOff otherwise)---+
581 </pre>
582
583 Note that the Saving state is present in both the offline state group and
584 online state group. Currently, the only way to determine what group is
585 assumed in a particular case is to remember the previous machine state: if
586 it was Running or Paused, then Saving is an online state, otherwise it is
587 an offline state. This inconsistency may be removed in one of the future
588 versions of VirtualBox by adding a new state.
589
590 <note internal="yes">
591 For whoever decides to touch this enum: In order to keep the
592 comparisons involving FirstOnline and LastOnline pseudo-states valid,
593 the numeric values of these states must be correspondingly updated if
594 needed: for any online VM state, the condition
595 <tt>FirstOnline &lt;= state &lt;= LastOnline</tt> must be
596 @c true. The same relates to transient states for which
597 the condition <tt>FirstOnline &lt;= state &lt;= LastOnline</tt> must be
598 @c true.

1124 <desc>
1125 The IVirtualBoxErrorInfo interface represents extended error information.
1126
1127 Extended error information can be set by VirtualBox components after
1128 unsuccessful or partially successful method invocation. This information
1129 can be retrieved by the calling party as an IVirtualBoxErrorInfo object
1130 and then shown to the client in addition to the plain 32-bit result code.
1131
1132 In MS COM, this interface extends the IErrorInfo interface,
1133 in XPCOM, it extends the nsIException interface. In both cases,
1134 it provides a set of common attributes to retrieve error
1135 information.
1136
1137 Sometimes invocation of some component's method may involve methods of
1138 other components that may also fail (independently of this method's
1139 failure), or a series of non-fatal errors may precede a fatal error that
1140 causes method failure. In cases like that, it may be desirable to preserve
1141 information about all errors happened during method invocation and deliver
1142 it to the caller. The <link to="#next"/> attribute is intended
1143 specifically for this purpose and allows to represent a chain of errors
1144 through a single IVirtualBoxErrorInfo object set after method invocation.
1145
1146 Note that errors are stored to a chain in the reverse order, i.e. the
1147 initial error object you query right after method invocation is the last
1148 error set by the callee, the object it points to in the @a next attribute
1149 is the previous error and so on, up to the first error (which is the last
1150 in the chain).

1152
1153 <attribute name="resultCode" type="long" readonly="yes">

1155 Result code of the error.
1156 Usually, it will be the same as the result code returned
1157 by the method that provided this error information, but not
1158 always. For example, on Win32, CoCreateInstance() will most
1159 likely return E_NOINTERFACE upon unsuccessful component
1160 instantiation attempt, but not the value the component factory
1161 returned. Value is typed 'long', not 'result',
1162 to make interface usable from scripting languages.

1722 <method name="createMachine">
1723 <desc>
1724 Creates a new virtual machine.
1725
1726 The new machine is created unregistered, with the initial configuration
1727 set according to the specified guest OS type. A typical sequence of
1728 actions to create a new virtual machine is as follows:
1729
1730 <ol>
1731 <li>
1732 Call this method to have a new machine created. The returned machine
1733 object will be "mutable" allowing to change any machine property.
1734 </li>
1735
1736 <li>
1737 Configure the machine using the appropriate attributes and methods.
1738 </li>
1739
1740 <li>
1741 Call <link to="IMachine::saveSettings" /> to write the settings
1742 to the machine's XML settings file. The configuration of the newly
1743 created machine will not be saved to disk until this method is
1744 called.
1745 </li>
1746
1747 <li>
1748 Call <link to="#registerMachine" /> to add the machine to the list
1749 of machines known to VirtualBox.
1750 </li>
1751 </ol>
1752
1753 You should specify valid name for the newly created machine when calling
1754 this method. See the <link to="IMachine::name"/> attribute description
1755 for more details about the machine name.
1756
1757 The specified guest OS type identifier must match an ID of one of known
1758 guest OS types listed in the <link to="IVirtualBox::guestOSTypes"/>
1759 array.
1760
1761 Every machine has a <i>settings file</i> that is used to store
1762 the machine configuration. This file is stored in a directory called the
1763 <i>machine settings subfolder</i>. Both the settings subfolder and file
1764 will have a name that corresponds to the name of the virtual machine.
1765 You can specify where to create the machine setting subfolder using the
1766 @a baseFolder argument. The base folder can be absolute (full path) or
1767 relative to the <link to="IVirtualBox::homeFolder">VirtualBox home
1768 directory</link>.
1769
1770 If @a baseFolder is a @c null or empty string (which is recommended), the
1771 <link to="ISystemProperties::defaultMachineFolder">default machine
1772 settings folder</link> will be used as a base folder for the created
1773 machine. Otherwise the given base folder will be used. In either case,
1774 the full path to the resulting settings file has the following
1775 structure:
1776 <pre>
1777 &lt;base_folder&gt;/&lt;machine_name&gt;/&lt;machine_name&gt;.xml
1778 </pre>
1779
1780 Note that if the resulting settings file already exists, this method
1781 will fail with <link to="VBOX_E_FILE_ERROR"/>.
1782
1783 Optionally, you may specify an UUID of to assign to the created machine.
1784 However, this is not recommended and you should normally pass an empty
1785 (@c null) UUID to this method so that a new UUID will be automatically
1786 generated for every created machine. You can use UUID
1787 00000000-0000-0000-0000-000000000000 as @c null value.
1788
1789 <note>
1790 There is no way to change the name of the settings file or
1791 subfolder of the created machine directly.

1829 the settings file of the machine created in "legacy" mode is not

1837
1838 Note that the configuration of the newly created machine is not
1839 saved to disk (and therefore no settings file is created)

2033 Note that the actual storage unit is not created by this method. In
2034 order to do it, and before you are able to attach the created medium
2035 to virtual machines, you must call one of the following methods to
2036 allocate a format-specific storage unit at the specified location:
2037 <ul>
2038 <li><link to="IMedium::createBaseStorage"/></li>
2039 <li><link to="IMedium::createDiffStorage"/></li>

2043 remain uninitialized until the medium storage unit is successfully
2044 created by one of the above methods.
2045
2046 After the storage unit is successfully created, the medium gets
2047 remembered by this VirtualBox installation and will be accessible
2048 through <link to="#getHardDisk"/> and <link to="#findHardDisk"/>
2049 methods. Remembered base medium are also returned as part of
2050 the <link to="#hardDisks"/> array. See IMedium for more details.
2051
2052 The list of all storage formats supported by this VirtualBox

2055 attribute is empty or @c null then the default storage format
2056 specified by <link to="ISystemProperties::defaultHardDiskFormat"/> will

2088 Opens a medium from an existing location, optionally replacing

2092 remembered by (known to) this VirtualBox installation and will be
2093 accessible through <link to="#getHardDisk"/> and
2094 <link to="#findHardDisk"/> methods. Remembered base media
2095 are also returned as part of the <link to="#hardDisks"/> array and can
2096 be attached to virtual machines. See IMedium for more details.

2098 If a differencing medium is to be opened by this method, the
2099 operation will succeed only if its parent medium and all ancestors,
2100 if any, are already known to this VirtualBox installation (for example,
2101 were opened by this method before).
2102
2103 This method tries to guess the storage format of the specified medium
2104 by reading medium data at the specified location.
2105
2106 If @a write is ReadWrite (which it should be), the image is opened for
2107 read/write access and must have according permissions, as VirtualBox
2108 may actually write status information into the disk's metadata sections.
2109
2110 Note that write access is required for all typical image usage in VirtualBox,
2111 since VirtualBox may need to write metadata such as a UUID into the image.
2112 The only exception is opening a source image temporarily for copying and
2113 cloning when the image will quickly be closed again.

2565 <method name="openSession">
2566 <desc>
2567 Opens a new direct session with the given virtual machine.
2568
2569 A direct session acts as a local lock on the given VM.
2570 There can be only one direct session open at a time for every
2571 virtual machine, protecting the VM from being manipulated by
2572 conflicting actions from different processes. Only after a
2573 direct session has been opened, one can change all VM settings
2574 and execute the VM in the process space of the session object.
2575
2576 Sessions therefore can be compared to mutex semaphores that
2577 lock a given VM for modification and execution.
2578 See <link to="ISession">ISession</link> for details.
2579
2580 <note>Unless you are writing a new VM frontend, you will not
2581 want to execute a VM in the current process. To spawn a new
2582 process that executes a VM, use
2583 <link to="IVirtualBox::openRemoteSession" />
2584 instead.</note>
2585
2586 Upon successful return, the session object can be used to
2587 get access to the machine and to the VM console.
2588
2589 In VirtualBox terminology, the machine becomes "mutable" after
2590 a session has been opened. Note that the "mutable" machine
2591 object, on which you may invoke IMachine methods to change its
2592 settings, will be a different object from the immutable IMachine
2593 objects returned by various IVirtualBox methods. To obtain a
2594 mutable IMachine object (upon which you can invoke settings methods),
2595 use the <link to="ISession::machine" /> attribute.
2596
2597 One must always call <link to="ISession::close" /> to release the
2598 lock on the machine, or the machine's state will eventually be
2599 set to "Aborted".
2600
2601 In other words, to change settings on a machine, the following
2602 sequence is typically performed:
2603
2604 <ol>
2605 <li>Call this method (openSession) to have a machine locked for
2606 the current session.</li>
2607
2608 <li>Obtain a mutable IMachine object from <link to="ISession::machine" />.</li>
2609
2610 <li>Change the settings of the machine.</li>
2611
2612 <li>Call <link to="IMachine::saveSettings" />.</li>

2650 <method name="openRemoteSession">
2651 <desc>
2652 Spawns a new process that executes a virtual machine (called a
2653 "remote session").
2654
2655 Opening a remote session causes the VirtualBox server to start a new
2656 process that opens a direct session with the given VM. As a result, the
2657 VM is locked by that direct session in the new process, preventing
2658 conflicting changes from other processes. Since sessions act as locks
2659 that prevent conflicting changes, one cannot open a remote session
2660 for a VM that already has another open session (direct or remote), or
2661 is currently in the process of opening one (see <link
2662 to="IMachine::sessionState"/>).
2663
2664 While the remote session still provides some level of control over the
2665 VM execution to the caller (using the <link to="IConsole" /> interface),
2666 not all VM settings are available for modification within the remote
2667 session context.
2668
2669 This operation can take some time (a new VM is started in a new process,
2670 for which memory and other resources need to be set up). Because of this,
2671 an <link to="IProgress" /> is returned to allow the caller to wait for this
2672 asynchronous operation to be completed. Until then, the remote session
2673 object remains in the closed state, and accessing the machine or its
2674 console through it is invalid. It is recommended to use
2675 <link to="IProgress::waitForCompletion" /> or similar calls to wait for
2676 completion.
2677
2678 As with all <link to="ISession" /> objects, it is recommended to call
2679 <link to="ISession::close" /> on the local session object once openRemoteSession()
2680 has been called. However, the session's state (see <link to="ISession::state" />)
2681 will not return to "Closed" until the remote session has also closed (i.e.
2682 until the VM is no longer running). In that case, however, the state of
2683 the session will automatically change back to "Closed".
2684
2685 Currently supported session types (values of the @a type
2686 argument) are:
2687 <ul>
2688 <li><tt>"gui"</tt>: VirtualBox Qt GUI session</li>
2689 <li><tt>"vrdp"</tt>: VirtualBox VRDP Server session</li>
2690 <li><tt>"sdl"</tt>: VirtualBox SDL GUI session</li>
2691 </ul>
2692
2693 The @a environment argument is a string containing definitions of
2694 environment variables in the following format:
2695 @code
2696 NAME[=VALUE]\n
2697 NAME[=VALUE]\n
2698 ...
2699 @endcode
2700 where <tt>\\n</tt> is the new line character. These environment
2701 variables will be appended to the environment of the VirtualBox server
2702 process. If an environment variable exists both in the server process
2703 and in this list, the value from this list takes precedence over the
2704 server's variable. If the value of the environment variable is
2705 omitted, this variable will be removed from the resulting environment.
2706 If the environment string is @c null or empty, the server environment
2707 is inherited by the started process as is.

2840 <desc>
2841 Blocks the caller until any of the properties represented by the
2842 @a what argument changes the value or until the given timeout interval
2843 expires.
2844
2845 The @a what argument is a comma separated list of property masks that
2846 describe properties the caller is interested in. The property mask is
2847 a string in the following format:
2848
2849 <pre>
2850 [[group.]subgroup.]name
2851 </pre>
2852
2853 where @c name is the property name and @c group, @c subgroup are zero
2854 or more property group specifiers. Each element (group or name) in
2855 the property mask may be either a Latin string or an asterisk symbol
2856 (@c "*") which is used to match any string for the given element. A
2857 property mask that doesn't contain asterisk symbols represents a
2858 single fully qualified property name.
2859
2860 Groups in the fully qualified property name go from more generic (the
2861 left-most part) to more specific (the right-most part). The first
2862 element is usually a name of the object the property belongs to. The
2863 second element may be either a property name, or a child object name,
2864 or an index if the preceding element names an object which is one of
2865 many objects of the same type. This way, property names form a
2866 hierarchy of properties. Here are some examples of property names:
2867
2868 <table>
2869 <tr>
2870 <td><tt>VirtualBox.version</tt></td>
2871 <td><link to="IVirtualBox::version"/> property</td>
2872 </tr>
2873 <tr>
2874 <td><tt>Machine.&lt;UUID&gt;.name</tt></td>
2875 <td><link to="IMachine::name"/> property of the machine with the
2876 given UUID</td>
2877 </tr>
2878 </table>
2879
2880 Most property names directly correspond to the properties of objects
2881 (components) provided by the VirtualBox library and may be used to
2882 track changes to these properties. However, there may be
2883 pseudo-property names that don't correspond to any existing object's
2884 property directly, as well as there may be object properties that
2885 don't have a corresponding property name that is understood by this
2886 method, and therefore changes to such properties cannot be
2887 tracked. See individual object's property descriptions to get a
2888 fully qualified property name that can be used with this method (if
2889 any).
2890
2891 There is a special property mask @c "*" (i.e. a string consisting of a
2892 single asterisk symbol) that can be used to match all properties.
2893 Below are more examples of property masks:
2894
2895 <table>
2896 <tr>
2897 <td><tt>VirtualBox.*</tt></td>
2898 <td>Track all properties of the VirtualBox object</td>
2899 </tr>
2900 <tr>
2901 <td><tt>Machine.*.name</tt></td>
2902 <td>Track changes to the <link to="IMachine::name"/> property of
2903 all registered virtual machines</td>

3147 Represents a platform-independent appliance in OVF format. An instance of this is returned
3148 by <link to="IVirtualBox::createAppliance" />, which can then be used to import and export
3149 appliances with VirtualBox.
3150
3151 The OVF standard suggests two different physical file formats:
3152
3153 <ol>
3154 <li>If the OVF is distributed as a set of files, then @a file must be a fully qualified
3155 path name to an existing OVF descriptor file with an <tt>.ovf</tt> file extension. If
3156 this descriptor file references other files, as OVF appliances distributed as a set of
3157 files most likely do, those files must be in the same directory as the descriptor file.</li>
3158
3159 <li>If the OVF is distributed as a single file, it must be in TAR format and have the
3160 <tt>.ova</tt> file extension. This TAR file must then contain at least the OVF descriptor
3161 files and optionally other files.
3162
3163 At this time, VirtualBox does not not yet support the packed (TAR) variant; support will
3164 be added with a later version.</li>
3165 </ol>
3166
3167 <b>Importing</b> an OVF appliance into VirtualBox as instances of
3168 <link to="IMachine" /> involves the following sequence of API calls:
3169
3170 <ol>
3171 <li>Call <link to="IVirtualBox::createAppliance" />. This will create an empty IAppliance object.
3172 </li>
3173
3174 <li>On the new object, call <link to="#read" /> with the full path of the OVF file you
3175 would like to import. So long as this file is syntactically valid, this will succeed
3176 and return an instance of IAppliance that contains the parsed data from the OVF file.
3177 </li>
3178
3179 <li>Next, call <link to="#interpret" />, which analyzes the OVF data and sets up the
3180 contents of the IAppliance attributes accordingly. These can be inspected by a
3181 VirtualBox front-end such as the GUI, and the suggestions can be displayed to the
3182 user. In particular, the <link to="#virtualSystemDescriptions" /> array contains
3183 instances of <link to="IVirtualSystemDescription" /> which represent the virtual
3184 systems in the OVF, which in turn describe the virtual hardware prescribed by the
3185 OVF (network and hardware adapters, virtual disk images, memory size and so on).
3186 The GUI can then give the user the option to confirm and/or change these suggestions.
3187 </li>
3188
3189 <li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
3190 virtual system to override the suggestions made by the interpret() routine.
3191 </li>
3192
3193 <li>Finally, call <link to="#importMachines" /> to create virtual machines in
3194 VirtualBox as instances of <link to="IMachine" /> that match the information in the
3195 virtual system descriptions.
3196 </li>
3197 </ol>
3198
3199 <b>Exporting</b> VirtualBox machines into an OVF appliance involves the following steps:
3200
3201 <ol>
3202 <li>As with importing, first call <link to="IVirtualBox::createAppliance" /> to create
3203 an empty IAppliance object.
3204 </li>
3205
3206 <li>For each machine you would like to export, call <link to="IMachine::export" />
3207 with the IAppliance object you just created. This creates an instance of
3208 <link to="IVirtualSystemDescription" /> inside the appliance.
3209 </li>
3210
3211 <li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
3212 virtual system to override the suggestions made by the export() routine.
3213 </li>
3214
3215 <li>Finally, call <link to="#write" /> with a path specification to have the OVF
3216 file written.</li>
3217 </ol>
3218
3219 </desc>
3220
3221 <attribute name="path" type="wstring" readonly="yes">
3222 <desc>Path to the main file of the OVF appliance, which is either the <tt>.ovf</tt> or

3234
3235 The caller should be prepared for additional fields being appended to
3236 this string in future versions of VirtualBox and therefore check for
3237 the number of tabs in the strings returned.

3448
3449 The list below identifies the value sets that are possible depending on the
3450 <link to="VirtualSystemDescriptionType" /> enum value in the array item in aTypes[]. In each case,
3451 the array item with the same index in aOvfValues[] will contain the original value as contained
3452 in the OVF file (just for informational purposes), and the corresponding item in aVBoxValues[]
3453 will contain a suggested value to be used for VirtualBox. Depending on the description type,
3454 the aExtraConfigValues[] array item may also be used.
3455
3456 <ul>
3457 <li>
3458 "OS": the guest operating system type. There must be exactly one such array item on import. The
3459 corresponding item in aVBoxValues[] contains the suggested guest operating system for VirtualBox.
3460 This will be one of the values listed in <link to="IVirtualBox::guestOSTypes" />. The corresponding
3461 item in aOvfValues[] will contain a numerical value that described the operating system in the OVF.
3462 </li>
3463 <li>
3464 "Name": the name to give to the new virtual machine. There can be at most one such array item;
3465 if none is present on import, then an automatic name will be created from the operating system
3466 type. The correponding item im aOvfValues[] will contain the suggested virtual machine name
3467 from the OVF file, and aVBoxValues[] will contain a suggestion for a unique VirtualBox
3468 <link to="IMachine" /> name that does not exist yet.
3469 </li>
3470 <li>
3471 "Description": an arbitrary description.
3472 </li>
3473 <li>
3474 "License": the EULA section from the OVF, if present. It is the responsibility of the calling
3475 code to display such a license for agreement; the Main API does not enforce any such policy.
3476 </li>
3477 <li>
3478 Miscellaneous: reserved for future use.
3479 </li>
3480 <li>
3481 "CPU": the number of CPUs. There can be at most one such item, which will presently be ignored.
3482 </li>
3483 <li>
3484 "Memory": the amount of guest RAM, in bytes. There can be at most one such array item; if none
3485 is present on import, then VirtualBox will set a meaningful default based on the operating system
3486 type.
3487 </li>
3488 <li>
3489 "HarddiskControllerIDE": an IDE hard disk controller. There can be at most one such item. This
3490 has no value in aOvfValues[] or aVBoxValues[].
3491 The matching item in the aRefs[] array will contain an integer that items of the "Harddisk"
3492 type can use to specify which hard disk controller a virtual disk should be connected to.
3493 </li>
3494 <li>
3495 "HarddiskControllerSATA": an SATA hard disk controller. There can be at most one such item. This
3496 has no value in aOvfValues[] or aVBoxValues[].
3497 The matching item in the aRefs[] array will be used as with IDE controllers (see above).
3498 </li>
3499 <li>
3500 "HarddiskControllerSCSI": a SCSI hard disk controller. There can be at most one such item.
3501 The items in aOvfValues[] and aVBoxValues[] will either be "LsiLogic" or "BusLogic".
3502 The matching item in the aRefs[] array will be used as with IDE controllers (see above).
3503 </li>
3504 <li>
3505 "HardDiskImage": a virtual hard disk, most probably as a reference to an image file. There can be an
3506 arbitrary number of these items, one for each virtual disk image that accompanies the OVF.
3507
3508 The array item in aOvfValues[] will contain the file specification from the OVF file (without
3509 a path since the image file should be in the same location as the OVF file itself), whereas the
3510 item in aVBoxValues[] will contain a qualified path specification to where VirtualBox uses the
3511 hard disk image. This means that on import the image will be copied and converted from the
3512 "ovf" location to the "vbox" location; on export, this will be handled the other way round.
3513 On import, the target image will also be registered with VirtualBox.
3514
3515 The matching item in the aExtraConfigValues[] array must contain a string of the following
3516 format: "controller=&lt;index&gt;;channel=&lt;c&gt;"
3517 In this string, &lt;index&gt; must be an integer specifying the hard disk controller to connect
3518 the image to. That number must be the index of an array item with one of the hard disk controller
3519 types (HarddiskControllerSCSI, HarddiskControllerSATA, HarddiskControllerIDE).
3520 In addition, &lt;c&gt; must specify the channel to use on that controller. For IDE controllers,
3521 this can range from 0-3 (which VirtualBox will interpret as primary master, primary slave, secondary master and
3522 secondary slave. For SATA and SCSI controllers, the channel can range from 0-29.
3523 </li>
3524 <li>
3525 "NetworkAdapter": a network adapter. The array item in aVBoxValues[] will specify the hardware
3526 for the network adapter, whereas the array item in aExtraConfigValues[] will have a string
3527 of the "type=&lt;X&gt;" format, where &lt;X&gt; must be either "NAT" or "Bridged".
3528 </li>
3529 <li>
3530 "USBController": a USB controller. There can be at most one such item. If and only if such an
3531 item ispresent, USB support will be enabled for the new virtual machine.
3532 </li>
3533 <li>
3534 "SoundCard": a sound card. There can be at most one such item. If and only if such an item is
3535 present, sound support will be enabled for the new virtual machine. Note that the virtual
3536 machine in VirtualBox will always be presented with the standard VirtualBox soundcard, which
3537 may be different from the virtual soundcard expected by the appliance.

4103 The IMachine interface represents a virtual machine, or guest, created
4104 in VirtualBox.
4105
4106 This interface is used in two contexts. First of all, a collection of
4107 objects implementing this interface is stored in the
4108 <link to="IVirtualBox::machines"/> attribute which lists all the virtual
4109 machines that are currently registered with this VirtualBox
4110 installation. Also, once a session has been opened for the given virtual
4111 machine (e.g. the virtual machine is running), the machine object
4112 associated with the open session can be queried from the session object;
4113 see <link to="ISession"/> for details.
4114
4115 The main role of this interface is to expose the settings of the virtual
4116 machine and provide methods to change various aspects of the virtual
4117 machine's configuration. For machine objects stored in the
4118 <link to="IVirtualBox::machines"/> collection, all attributes are
4119 read-only unless explicitly stated otherwise in individual attribute
4120 and method descriptions. In order to change a machine setting, a session
4121 for this machine must be opened using one of
4122 <link to="IVirtualBox::openSession"/>,
4123 <link to="IVirtualBox::openRemoteSession"/> or
4124 <link to="IVirtualBox::openExistingSession"/> methods. After the
4125 session has been successfully opened, a mutable machine object needs to
4126 be queried from the session object and then the desired settings changes
4127 can be applied to the returned object using IMachine attributes and
4128 methods. See the <link to="ISession"/> interface description for more
4129 information about sessions.
4130
4131 Note that IMachine does not provide methods to control virtual machine
4132 execution (such as start the machine, or power it down) -- these methods
4133 are grouped in a separate interface called <link to="IConsole" />.

4142 <attribute name="accessible" type="boolean" readonly="yes">
4143 <desc>
4144 Whether this virtual machine is currently accessible or not.
4145
4146 A machine is always deemed accessible unless it is registered <i>and</i>
4147 its settings file cannot be read or parsed (either because the file itself
4148 is unavailable or has invalid XML contents).
4149
4150 Every time this property is read, the accessibility state of
4151 this machine is re-evaluated. If the returned value is @c false,
4152 the <link to="#accessError"/> property may be used to get the
4153 detailed error information describing the reason of
4154 inaccessibility, including XML error messages.
4155
4156 When the machine is inaccessible, only the following properties
4157 can be used on it:
4158 <ul>
4159 <li><link to="#parent"/></li>
4160 <li><link to="#id"/></li>
4161 <li><link to="#settingsFilePath"/></li>
4162 <li><link to="#accessible"/></li>
4163 <li><link to="#accessError"/></li>
4164 </ul>
4165
4166 An attempt to access any other property or method will return
4167 an error.
4168
4169 The only possible action you can perform on an inaccessible
4170 machine is to unregister it using the
4171 <link to="IVirtualBox::unregisterMachine"/> call (or, to check
4172 for the accessibility state once more by querying this
4173 property).
4174
4175 <note>
4176 In the current implementation, once this property returns
4177 @c true, the machine will never become inaccessible
4178 later, even if its settings file cannot be successfully
4179 read/written any more (at least, until the VirtualBox
4180 server is restarted). This limitation may be removed in
4181 future releases.

4190
4191 Reading this property is only valid after the last call to
4192 <link to="#accessible"/> returned @c false (i.e. the
4193 machine is currently unaccessible). Otherwise, a @c null
4194 IVirtualBoxErrorInfo object will be returned.

4199 <desc>
4200 Name of the virtual machine.
4201
4202 Besides being used for human-readable identification purposes
4203 everywhere in VirtualBox, the virtual machine name is also used
4204 as a name of the machine's settings file and as a name of the
4205 subdirectory this settings file resides in. Thus, every time you
4206 change the value of this property, the settings file will be
4207 renamed once you call <link to="#saveSettings"/> to confirm the
4208 change. The containing subdirectory will be also renamed, but
4209 only if it has exactly the same name as the settings file
4210 itself prior to changing this property (for backward compatibility
4211 with previous API releases). The above implies the following
4212 limitations:
4213 <ul>
4214 <li>The machine name cannot be empty.</li>
4215 <li>The machine name can contain only characters that are valid
4216 file name characters according to the rules of the file
4217 system used to store VirtualBox configuration.</li>
4218 <li>You cannot have two or more machines with the same name
4219 if they use the same subdirectory for storing the machine
4220 settings files.</li>
4221 <li>You cannot change the name of the machine if it is running,
4222 or if any file in the directory containing the settings file
4223 is being used by another running machine or by any other
4224 process in the host operating system at a time when
4225 <link to="#saveSettings"/> is called.
4226 </li>
4227 </ul>
4228 If any of the above limitations are hit, <link to="#saveSettings"/>
4229 will return an appropriate error message explaining the exact
4230 reason and the changes you made to this machine will not be
4231 saved.
4232 <note>
4233 For "legacy" machines created using the
4234 <link to="IVirtualBox::createLegacyMachine"/> call,
4235 the above naming limitations do not apply because the
4236 machine name does not affect the settings file name.
4237 The settings file name remains the same as it was specified
4238 during machine creation and never changes.

4673 Attaches a device and optionally mounts a medium to the given storage
4674 controller (<link to="IStorageController" />, identified by @a name),
4675 at the indicated port and device.
4676
4677 This method is intended for managing storage devices in general (it works
4678 for both fixed and removable media). For storage devices supporting removable
4679 media (such as DVDs and floppies), you can also use <link to="IMedium::mountMedium"/>
4680 for changing the media while the machine is running.
4681
4682 For the IDE bus, the @a controllerPort parameter can be either
4683 @c 0 or @c 1, to specify the primary or secondary IDE controller,
4684 respectively. For each of these, @a device can then be either @c 0 or @c 1,
4685 to specify the master or the slave device, respectively. (In the
4686 default configuration of virtual machines, the secondary master is
4687 used for a CD/DVD drive.)
4688
4689 For an SATA controller, @a controllerPort must be a number ranging
4690 from @c 0 to @c 29. For a SCSI controller, @a controllerPort must
4691 be a number ranging from @c 0 to @c 15.
4692
4693 For both SCSI and SATA, the @a device parameter is unused and must
4694 be @c 0.
4695
4696 For fixed media such as hard disks, the given medium identifier cannot
4697 be a zero UUID. It may be a zero UUID for removable media such as DVDs
4698 and floppies.
4699
4700 After calling this returns successfully, a new instance of
4701 <link to="IMediumAttachment"/> will appear in the machine's list of medium
4702 attachments (<link to="IMachine::mediumAttachments"/>).
4703
4704 The specified device slot must not have a device attached to it,
4705 or this method will fail.

4708 information about attaching media.

4711 You cannot attach a device to a running machine. Also, you cannot
4712 attach a device to a newly created machine until this machine's
4713 settings are saved to disk using <link to="#saveSettings"/>.
4714 </note>
4715 <note>
4716 If the medium is being attached indirectly, a new differencing medium
4717 will implicitly be created for it and attached instead. If the
4718 changes made to the machine settings (including this indirect
4719 attachment) are later cancelled using <link to="#discardSettings"/>,
4720 this implicitly created differencing medium will implicitly
4721 be deleted.

5922 This interface is used by a client of the Main API that need to
5923 be notified of events. For example, a graphical user interface
5924 can use this to learn about machine state changes so they can
5925 update the list of virtual machines without having to rely
5926 on polling.
5927
5928 Whenever relevant events occur in VirtualBox, the callbacks in
5929 objects of this interface are called. In order for this to be
5930 useful, a client needs to create its own subclass that implements
5931 this interface in which the methods for the relevant callbacks
5932 are overridden. An instance of this subclass interface can then
5933 be passed to <link to="IConsole::registerCallback" />.

5974
5975 The @a shape buffer contains a 1-bpp (bits per pixel) AND mask
5976 followed by a 32-bpp XOR (color) mask.
5977
5978 For pointers without alpha channel the XOR mask pixels are 32
5979 bit values: (lsb)BGR0(msb). For pointers with alpha channel
5980 the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
5981
5982 An AND mask is used for pointers with alpha channel, so if the
5983 callback does not support alpha, the pointer could be
5984 displayed as a normal color pointer.
5985
5986 The AND mask is a 1-bpp bitmap with byte aligned scanlines. The
5987 size of the AND mask therefore is <tt>cbAnd = (width + 7) / 8 *
5988 height</tt>. The padding bits at the end of each scanline are
5989 undefined.
5990
5991 The XOR mask follows the AND mask on the next 4-byte aligned
5992 offset: <tt>uint8_t *pXor = pAnd + (cbAnd + 3) &amp; ~3</tt>.
5993 Bytes in the gap between the AND and the XOR mask are undefined.
5994 The XOR mask scanlines have no gap between them and the size of
5995 the XOR mask is: <tt>cXor = width * 4 * height</tt>.
5996
5997 <note>
5998 If @a shape is 0, only the pointer visibility is changed.

6177 Notification when an error happens during the virtual
6178 machine execution.
6179
6180 There are three kinds of runtime errors:
6181 <ul>
6182 <li><i>fatal</i></li>
6183 <li><i>non-fatal with retry</i></li>
6184 <li><i>non-fatal warnings</i></li>
6185 </ul>
6186
6187 <b>Fatal</b> errors are indicated by the @a fatal parameter set
6188 to @c true. In case of fatal errors, the virtual machine
6189 execution is always paused before calling this notification, and
6190 the notification handler is supposed either to immediately save
6191 the virtual machine state using <link to="IConsole::saveState"/>
6192 or power it off using <link to="IConsole::powerDown"/>.
6193 Resuming the execution can lead to unpredictable results.
6194
6195 <b>Non-fatal</b> errors and warnings are indicated by the
6196 @a fatal parameter set to @c false. If the virtual machine
6197 is in the Paused state by the time the error notification is
6198 received, it means that the user can <i>try to resume</i> the machine
6199 execution after attempting to solve the problem that caused the
6200 error. In this case, the notification handler is supposed
6201 to show an appropriate message to the user (depending on the
6202 value of the @a id parameter) that offers several actions such
6203 as <i>Retry</i>, <i>Save</i> or <i>Power Off</i>. If the user
6204 wants to retry, the notification handler should continue
6205 the machine execution using the <link to="IConsole::resume"/>
6206 call. If the machine execution is not Paused during this
6207 notification, then it means this notification is a <i>warning</i>
6208 (for example, about a fatal condition that can happen very soon);
6209 no immediate action is required from the user, the machine
6210 continues its normal execution.
6211
6212 Note that in either case the notification handler
6213 <b>must not</b> perform any action directly on a thread
6214 where this notification is called. Everything it is allowed to
6215 do is to post a message to another thread that will then talk
6216 to the user and take the corresponding action.
6217
6218 Currently, the following error identifiers are known:
6219 <ul>
6220 <li><tt>"HostMemoryLow"</tt></li>
6221 <li><tt>"HostAudioNotResponding"</tt></li>
6222 <li><tt>"VDIStorageFull"</tt></li>

6279 requests the console window to be activated and brought to
6280 foreground on the desktop of the host PC.
6281
6282 This notification should cause the VM console process to
6283 perform the requested action as described above. If it is
6284 impossible to do it at a time of this notification, this
6285 method should return a failure.
6286
6287 Note that many modern window managers on many platforms
6288 implement some sort of focus stealing prevention logic, so
6289 that it may be impossible to activate a window without the
6290 help of the currently active application (which is supposedly
6291 an initiator of this notification). In this case, this method
6292 must return a non-zero identifier that represents the
6293 top-level window of the VM console process. The caller, if it
6294 represents a currently active process, is responsible to use
6295 this identifier (in a platform-dependent manner) to perform
6296 actual window activation.
6297
6298 This method must set @a winId to zero if it has performed all
6299 actions necessary to complete the request and the console
6300 window is now active and in foreground, to indicate that no
6301 further action is required on the caller's side.

6438 The IConsole interface represents an interface to control virtual
6439 machine execution.
6440
6441 The console object that implements the IConsole interface is obtained
6442 from a session object after the session for the given machine has been
6443 opened using one of <link to="IVirtualBox::openSession"/>,
6444 <link to="IVirtualBox::openRemoteSession"/> or
6445 <link to="IVirtualBox::openExistingSession"/> methods.
6446
6447 Methods of the IConsole interface allow the caller to query the current
6448 virtual machine execution state, pause the machine or power it down, save
6449 the machine state or take a snapshot, attach and detach removable media
6450 and so on.

6719 be restored and the machine will continue its execution from
6720 the place where it was saved.
6721
6722 This operation differs from taking a snapshot to the effect
6723 that it doesn't create new differencing media. Also, once
6724 the machine is powered up from the state saved using this method,
6725 the saved state is deleted, so it will be impossible to return
6726 to this state later.

6732 Together with the impossibility to change any VM settings when it is

6988 <method name="deleteSnapshot">
6989 <desc>
6990 Starts discarding the specified snapshot asynchronously.
6991 See <link to="ISnapshot" /> for an introduction to snapshots.
6992
6993 The execution state and settings of the associated machine stored in
6994 the snapshot will be deleted. The contents of all differencing media of
6995 this snapshot will be merged with the contents of their dependent child
6996 media to keep the medium chain valid (in other words, all changes
6997 represented by media being discarded will be propagated to their child
6998 medium). After that, this snapshot's differencing medium will be
6999 deleted. The parent of this snapshot will become a new parent for all
7000 its child snapshots.
7001
7002 If the discarded snapshot is the current one, its parent
7003 snapshot will become a new current snapshot. The current machine
7004 state is not directly affected in this case, except that
7005 currently attached differencing media based on media
7006 of the discarded snapshot will be also merged as described
7007 above.
7008
7009 If the discarded snapshot is the first one (the root snapshot)
7010 and it has exactly one child snapshot, this child snapshot will
7011 become the first snapshot after discarding. If there are no
7012 children at all (i.e. the first snapshot is the only snapshot of
7013 the machine), both the current and the first snapshot of the
7014 machine will be set to @c null. In all other cases, the first
7015 snapshot cannot be discarded.
7016
7017 You cannot discard the snapshot if it
7018 stores <link to="MediumType_Normal">normal</link> (non-differencing)
7019 media that have differencing media based on them. Snapshots of
7020 such kind can be discarded only when every normal medium has either
7021 no children at all or exactly one child. In the former case, the normal
7022 medium simply becomes unused (i.e. not attached to any VM). In the
7023 latter case, it receives all the changes stored in the child medium,
7024 and then it replaces the child medium in the configuration of the
7025 corresponding snapshot or machine.
7026
7027 Also, you cannot discard the snapshot if it stores media
7028 (of any type) having differencing child media that belong
7029 to other machines. Such snapshots can be only discarded after
7030 you discard all snapshots of other machines containing "foreign"
7031 child media, or detach these "foreign" child media from machines
7032 they are attached to.
7033
7034 One particular example of the snapshot storing normal media
7035 is the first snapshot of a virtual machine that had normal media
7036 attached when taking the snapshot. Be careful when
7037 discarding such snapshots because this implicitly commits
7038 changes (made since the snapshot being discarded has been taken)
7039 to normal media (as described above), which may be not what
7040 you want.
7041
7042 The virtual machine is put to
7043 the <link to="MachineState_Discarding">Discarding</link> state until
7044 the discard operation is completed.
7045
7046 <note>
7047 The machine must not be running, otherwise the operation
7048 will fail.
7049 </note>
7050
7051 <note>
7052 Child media of all normal media of the discarded snapshot
7053 must be accessible (see <link to="IMedium::state"/>) for this
7054 operation to succeed. In particular, this means that all virtual
7055 machines, whose media are directly or indirectly based on the
7056 media of discarded snapshot, must be powered off.
7057 </note>
7058 <note>
7059 Merging medium contents can be very time and disk space
7060 consuming, if these media are big in size and have many
7061 children. However, if the snapshot being discarded is the last
7062 (head) snapshot on the branch, the operation will be rather
7063 quick.
7064 </note>
7065 <note>
7066 Note that discarding the current snapshot
7067 will implicitly call <link to="IMachine::saveSettings"/> to
7068 make all current machine settings permanent.

7929 List of all medium storage formats supported by this VirtualBox
7930 installation.
7931
7932 Keep in mind that the medium format identifier
7933 (<link to="IMediumFormat::id"/>) used in other API calls like
7934 <link to="IVirtualBox::createHardDisk"/> to refer to a particular
7935 medium format is a case-insensitive string. This means that, for
7936 example, all of the following strings:
7937 <pre>
7938 "VDI"
7939 "vdi"
7940 "VdI"</pre>
7941 refer to the same medium format.
7942
7943 Note that the virtual medium framework is backend-based, therefore
7944 the list of supported formats depends on what backends are currently
7945 installed.

7953 <attribute name="defaultHardDiskFormat" type="wstring">
7954 <desc>
7955 Identifier of the default medium format used by VirtualBox.
7956
7957 The medium format set by this attribute is used by VirtualBox
7958 when the medium format was not specified explicitly. One example is
7959 <link to="IVirtualBox::createHardDisk"/> with the empty
7960 format argument. A more complex example is implicit creation of
7961 differencing media when taking a snapshot of a virtual machine:
7962 this operation will try to use a format of the parent medium first
7963 and if this format does not support differencing media the default
7964 format specified by this argument will be used.
7965
7966 The list of supported medium formats may be obtained by the
7967 <link to="#mediaFormats"/> call. Note that the default medium
7968 format must have a capability to create differencing media;
7969 otherwise operations that create media implicitly may fail
7970 unexpectedly.

7972 The initial value of this property is <tt>"VDI"</tt> in the current

7990 Library that provides authentication for VRDP clients. The library

7992 in the VM RemoteDisplay configuration.
7993
7994 The system library extension (".DLL" or ".so") must be omitted.
7995 A full path can be specified; if not, then the library must reside on the
7996 system's default library path.
7997
7998 The default value of this property is <tt>"VRDPAuth"</tt>. There is a library
7999 of that name in one of the default VirtualBox library directories.

8015 in the VM RemoteDisplay configuration and will be called from
8016 within the <link to="IWebsessionManager::logon" /> implementation.
8017
8018 As opposed to <link to="ISystemProperties::remoteDisplayAuthLibrary" />,
8019 there is no per-VM setting for this, as the webservice is a global
8020 resource (if it is running). Only for this setting (for the webservice),
8021 setting this value to a literal <tt>"null"</tt> string disables authentication,
8022 meaning that <link to="IWebsessionManager::logon" /> will always succeed,
8023 no matter what user name and password are supplied.
8024
8025 The initial value of this property is <tt>"VRDPAuth"</tt>,
8026 meaning that the webservice will use the same authentication
8027 library that is used by default for VBoxVRDP (again, see
8028 <link to="ISystemProperties::remoteDisplayAuthLibrary" />).
8029 The format and calling convention of authentication libraries
8030 is the same for the webservice as it is for VBoxVRDP.

8311 continues to run after a method call returns. For example,
8312 <link to="IConsole::saveState" />, which saves the state of
8313 a running virtual machine, can take a long time to complete.
8314 To be able to display a progress bar, a user interface such as
8315 the VirtualBox graphical user interface can use the IProgress
8316 object returned by that method.
8317
8318 Note that IProgress is a "read-only" interface in the sense
8319 that only the VirtualBox internals behind the Main API can
8320 create and manipulate progress objects, whereas client code
8321 can only use the IProgress object to monitor a task's
8322 progress and, if <link to="#cancelable" /> is @c true,
8323 cancel the task by calling <link to="#cancel" />.
8324
8325 A task represented by IProgress consists of either one or
8326 several sub-operations that run sequentially, one by one (see
8327 <link to="#operation" /> and <link to="#operationCount" />).
8328 Every operation is identified by a number (starting from 0)
8329 and has a separate description.
8330
8331 You can find the individual percentage of completion of the current
8332 operation in <link to="#operationPercent" /> and the
8333 percentage of completion of the task as a whole
8334 in <link to="#percent" />.
8335
8336 Similarly, you can wait for the completion of a particular
8337 operation via <link to="#waitForOperationCompletion" /> or
8338 for the completion of the whole task via
8339 <link to="#waitForCompletion" />.

8501 wsmap="managed"
8502 >
8503 <desc>
8504 The ISnapshot interface represents a snapshot of the virtual
8505 machine.
8506
8507 Together with the differencing media that are created
8508 when a snapshot is taken, a machine can be brought back to
8509 the exact state it was in when the snapshot was taken.
8510
8511 The ISnapshot interface has no methods, only attributes; snapshots
8512 are controlled through methods of the <link to="IConsole" /> interface
8513 which also manage the media associated with the snapshot.
8514 The following operations exist:
8515
8516 <ul>
8517 <li><link to="IConsole::takeSnapshot"/>: creates a new snapshot
8518 by creating new, empty differencing images for the machine's
8519 media and saving the VM settings and (if the VM is running)
8520 the current VM state in the snapshot.
8521
8522 The differencing images will then receive all data written to
8523 the machine's media, while their parent (base) images
8524 remain unmodified after the snapshot has been taken (see
8525 <link to="IMedium" /> for details about differencing images).
8526 This simplifies restoring a machine to the state of a snapshot:
8527 only the differencing images need to be deleted.
8528
8529 The current machine state is not changed by taking a snapshot.
8530 If the machine is running, it will resume execution after the
8531 snapshot has been taken.
8532 </li>
8533
8534 <li><link to="IConsole::restoreSnapshot"/>: this goes back to
8535 a previous snapshot. This resets the machine's state to that of
8536 the previous snapshot by deleting the differencing image of each
8537 of the machine's media and setting the machine's settings
8538 and state to the state that was saved in the snapshot (if any).
8539
8540 This destroys the machine's current state.
8541 </li>
8542
8543 <li><link to="IConsole::deleteSnapshot"/>: deletes a snapshot
8544 without affecting the current machine state.
8545
8546 This does not change the machine, but instead frees the resources
8547 allocated when the snapshot was taken: the settings and machine state
8548 is deleted (if any), and the snapshot's differencing image for each
8549 of the machine's media gets merged with its parent image.
8550
8551 Neither the current machine state nor other snapshots are affected
8552 by this operation, except that parent media will be modified
8553 to contain the disk data associated with the snapshot being deleted.
8554 </li>
8555 </ul>
8556
8557 Each snapshot contains the settings of the virtual machine (hardware
8558 configuration etc.). In addition, if the machine was running when the
8559 snapshot was taken (<link to="IMachine::state"/> is <link to="MachineState_Running"/>),
8560 the current VM state is saved in the snapshot (similarly to what happens
8561 when a VM's state is saved). The snapshot is then said to
8562 be <i>online</i> because when restoring it, the VM will be running.
8563
8564 If the machine is saved (<link to="MachineState_Saved"/>), the snapshot
8565 receives a copy of the execution state file (<link to="IMachine::stateFilePath"/>).
8566
8567 Otherwise, if the machine was not running (<link to="MachineState_PoweredOff"/>
8568 or <link to="MachineState_Aborted"/>), the snapshot is <i>offline</i>;
8569 it then contains a so-called "zero execution state", representing a
8570 machine that is powered off.
8571
8572 <h3>Snapshot branches and the "current" snapshot</h3>
8573
8574 Snapshots can be chained, whereby every next snapshot is based on the
8575 previous one. This chaining is related to medium branching
8576 (see the <link to="IMedium"/> description) in that every time
8577 a new snapshot is created, a new differencing medium is implicitly
8578 created for all normal media attached to the machine.
8579
8580 Each virtual machine has a "current snapshot", identified by
8581 <link to="IMachine::currentSnapshot"/>. Presently, this is always set
8582 to the last snapshot in the chain. In a future version of VirtualBox,
8583 it will be possible to reset a machine's current state to that of an
8584 earlier snapshot without discarding the current state so that it will be
8585 possible to create alternative snapshot paths in a snapshot tree.
8586
8587 In the current implementation, multiple snapshot branches within one
8588 virtual machine are not allowed. Every machine has a single branch,
8589 and <link to="IConsole::takeSnapshot"/> operation adds a new
8590 snapshot to the top of that branch.

8830 The IMedium interface represents virtual storage for a machine's
8831 hard disks, CD/DVD or floppy drives. It will typically represent
8832 a disk image on the host, for example a VDI or VMDK file representing
8833 a virtual hard disk, or an ISO or RAW file representing virtual
8834 removable media, but can also point to a network location (e.g.
8835 for iSCSI targets).
8836
8837 Instances of IMedium are connected to virtual machines by way of
8838 medium attachments (see <link to="IMediumAttachment" />), which link
8839 the storage medium to a particular device slot of a storage controller
8840 of the virtual machine.
8841 In the VirtualBox API, virtual storage is therefore always represented
8842 by the following chain of object links:
8843
8844 <ul>
8845 <li><link to="IMachine::storageControllers"/> contains an array of
8846 storage controllers (IDE, SATA, SCSI or a floppy controller;
8847 these are instances of <link to="IStorageController"/>).</li>
8848 <li><link to="IMachine::mediumAttachments"/> contains an array of
8849 medium attachments (instances of <link to="IMediumAttachment"/>),
8850 each containing a storage controller from the above array, a
8851 port/device specification, and an instance of IMedium representing
8852 the medium storage (image file).
8853
8854 For removable media, the storage medium is optional; a medium
8855 attachment with no medium represents a CD/DVD or floppy drive
8856 with no medium inserted. By contrast, hard disk attachments
8857 will always have an IMedium object attached.</li>
8858 <li>Each IMedium in turn points to a storage unit (such as a file
8859 on the host computer or a network resource) that holds actual
8860 data. This location is represented by the <link to="#location"/>
8861 attribute.</li>
8862 </ul>
8863
8864 Existing media are opened using the following methods, depending on the
8865 media type:
8866 <ul>
8867 <li><link to="IVirtualBox::openHardDisk"/></li>
8868 <li><link to="IVirtualBox::openDVDImage"/></li>
8869 <li><link to="IVirtualBox::openFloppyImage"/></li>
8870 </ul>
8871
8872 New hard disk media can be created with the VirtualBox API using the
8873 <link to="IVirtualBox::createHardDisk"/> method.
8874
8875 CD/DVD and floppy images (ISO and RAW files) are usually created outside
8876 VirtualBox, e.g. by storing a copy of the real medium of the corresponding
8877 type in a regular file.
8878
8879 Only for CD/DVDs and floppies, an IMedium instance can also represent a host
8880 drive; in that case the <link to="#id" /> attribute contains the UUID of
8881 one of the drives in <link to="IHost::DVDDrives" /> or <link to="IHost::floppyDrives" />.
8882
8883 <h3>Known media</h3>
8884
8885 When an existing medium is opened for the first time, it is automatically
8886 remembered by the given VirtualBox installation or, in other words, becomes
8887 a <i>known medium</i>. Known media are stored in the media
8888 registry transparently maintained by VirtualBox and stored in settings
8889 files so that this registry is preserved when VirtualBox is not running.
8890
8891 Newly created virtual media are remembered only when the associated
8892 storage unit is actually created.
8893
8894 All known media can be enumerated using
8895 <link to="IVirtualBox::hardDisks"/>,
8896 <link to="IVirtualBox::DVDImages"/> and
8897 <link to="IVirtualBox::floppyImages"/> attributes. Individual media can be
8898 quickly found by UUID using <link to="IVirtualBox::getHardDisk"/>
8899 and similar methods or by location using
8900 <link to="IVirtualBox::findHardDisk"/> and similar methods.
8901
8902 Only known media can be attached to virtual machines.
8903
8904 Removing known media from the media registry is performed when the given
8905 medium is closed using the <link to="#close"/> method or when its
8906 associated storage unit is deleted.
8907
8908 <h3>Accessibility checks</h3>
8909
8910 VirtualBox defers media accessibility checks until the <link to="#refreshState" />
8911 method is called explicitly on a medium. This is done to make the VirtualBox object
8912 ready for serving requests as fast as possible and let the end-user
8913 application decide if it needs to check media accessibility right away or not.
8914
8915 As a result, when VirtualBox starts up (e.g. the VirtualBox
8916 object gets created for the first time), all known media are in the
8917 "Inaccessible" state, but the value of the <link to="#lastAccessError"/>
8918 attribute is an empty string because no actual accessibility check has
8919 been made yet.
8920
8921 After calling <link to="#refreshState" />, a medium is considered
8922 <i>accessible</i> if its storage unit can be read. In that case, the
8923 <link to="#state"/> attribute has a value of "Created". If the storage
8924 unit cannot be read (for example, because it is located on a disconnected
8925 network resource, or was accidentally deleted outside VirtualBox),
8926 the medium is considered <i>inaccessible</i>, which is indicated by the
8927 "Inaccessible" state. The exact reason why the medium is inaccessible can be
8928 obtained by reading the <link to="#lastAccessError"/> attribute.
8929
8930 <h3>Medium types</h3>
8931
8932 There are three types of medium behavior (see <link to="MediumType" />):
8933 "normal", "immutable" and "writethrough", represented by the
8934 <link to="#type"/> attribute. The type of the medium defines how the
8935 medium is attached to a virtual machine and what happens when a
8936 <link to="ISnapshot">snapshot</link> of the virtual machine with the
8937 attached medium is taken. At the moment DVD and floppy media are always
8938 of type "writethrough".
8939
8940 All media can be also divided in two groups: <i>base</i> media and
8941 <i>differencing</i> media. A base medium contains all sectors of the
8942 medium data in its own storage and therefore can be used independently.
8943 In contrast, a differencing mediun is a "delta" to some other medium and
8944 contains only those sectors which differ from that other medium, which is
8945 then called a <i>parent</i>. The differencing medium is said to be
8946 <i>linked to</i> that parent. The parent may be itself a differencing
8947 medium, thus forming a chain of linked media. The last element in that
8948 chain must always be a base medium. Note that several differencing
8949 media may be linked to the same parent medium.
8950
8951 Differencing media can be distinguished from base media by querying the
8952 <link to="#parent"/> attribute: base media do not have parents they would
8953 depend on, so the value of this attribute is always @c null for them.
8954 Using this attribute, it is possible to walk up the medium tree (from the
8955 child medium to its parent). It is also possible to walk down the tree
8956 using the <link to="#children"/> attribute.
8957
8958 Note that the type of all differencing media is
8959 <link to="MediumType_Normal" />; all other values are meaningless for
8960 them. Base media may be of any type.
8961
8962 <h3>Creating hard disks</h3>
8963
8964 New base hard disks are created using
8965 <link to="IVirtualBox::createHardDisk"/>. Existing hard disks are
8966 opened using <link to="IVirtualBox::openHardDisk"/>. Differencing hard
8967 disks are usually implicitly created by VirtualBox when needed but may
8968 also be created explicitly using <link to="#createDiffStorage"/>.
8969
8970 After the hard disk is successfully created (including the storage unit)
8971 or opened, it becomes a known hard disk (remembered in the internal media
8972 registry). Known hard disks can be attached to a virtual machine, accessed
8973 through <link to="IVirtualBox::getHardDisk"/> and
8974 <link to="IVirtualBox::findHardDisk"/> methods or enumerated using the
8975 <link to="IVirtualBox::hardDisks"/> array (only for base hard disks).
8976
8977 The following methods, besides <link to="IMedium::close"/>,
8978 automatically remove the hard disk from the media registry:
8979 <ul>
8980 <li><link to="#deleteStorage"/></li>
8981 <li><link to="#mergeTo"/></li>
8982 </ul>
8983
8984 If the storage unit of the hard disk is a regular file in the host's
8985 file system then the rules stated in the description of the
8986 <link to="IMedium::location"/> attribute apply when setting its value. In
8987 addition, a plain file name without any path may be given, in which case
8988 the <link to="ISystemProperties::defaultHardDiskFolder"> default hard disk
8989 folder</link> will be prepended to it.
8990
8991 <h4>Automatic composition of the file name part</h4>
8992
8993 Another extension to the <link to="IMedium::location"/> attribute is that
8994 there is a possibility to cause VirtualBox to compose a unique value for
8995 the file name part of the location using the UUID of the hard disk. This
8996 applies only to hard disks in <link to="MediumState_NotCreated"/> state,
8997 e.g. before the storage unit is created, and works as follows. You set the
8998 value of the <link to="IMedium::location"/> attribute to a location
8999 specification which only contains the path specification but not the file
9000 name part and ends with either a forward slash or a backslash character.
9001 In response, VirtualBox will generate a new UUID for the hard disk and
9002 compose the file name using the following pattern:
9003 <pre>
9004 &lt;path&gt;/{&lt;uuid&gt;}.&lt;ext&gt;
9005 </pre>
9006 where <tt>&lt;path&gt;</tt> is the supplied path specification,
9007 <tt>&lt;uuid&gt;</tt> is the newly generated UUID and <tt>&lt;ext&gt;</tt>
9008 is the default extension for the storage format of this hard disk. After
9009 that, you may call any of the methods that create a new hard disk storage
9010 unit and they will use the generated UUID and file name.
9011
9012 <h3>Attaching Hard Disks</h3>
9013
9014 Hard disks are attached to virtual machines using the
9015 <link to="IMachine::attachDevice"/> method and detached using the
9016 <link to="IMachine::detachDevice"/> method. Depending on their
9017 <link to="#type"/>, hard disks are attached either
9018 <i>directly</i> or <i>indirectly</i>.
9019
9020 When a hard disk is being attached directly, it is associated with the
9021 virtual machine and used for hard disk operations when the machine is
9022 running. When a hard disk is being attached indirectly, a new differencing
9023 hard disk linked to it is implicitly created and this differencing hard
9024 disk is associated with the machine and used for hard disk operations.
9025 This also means that if <link to="IMachine::attachDevice"/> performs
9026 a direct attachment then the same hard disk will be returned in response
9027 to the subsequent <link to="IMachine::getMedium"/> call; however if
9028 an indirect attachment is performed then
9029 <link to="IMachine::getMedium"/> will return the implicitly created
9030 differencing hard disk, not the original one passed to <link
9031 to="IMachine::attachDevice"/>. In detail:
9032
9033 <ul>
9034 <li><b>Normal base</b> hard disks that do not have children (i.e.
9035 differencing hard disks linked to them) and that are not already
9036 attached to virtual machines in snapshots are attached <b>directly</b>.
9037 Otherwise, they are attached <b>indirectly</b> because having
9038 dependent children or being part of the snapshot makes it impossible
9039 to modify hard disk contents without breaking the integrity of the
9040 dependent party. The <link to="#readOnly"/> attribute allows to
9041 quickly determine the kind of the attachment for the given hard
9042 disk. Note that if a normal base hard disk is to be indirectly
9043 attached to a virtual machine with snapshots then a special
9044 procedure called <i>smart attachment</i> is performed (see below).</li>
9045 <li><b>Normal differencing</b> hard disks are like normal base hard disks:
9046 they are attached <b>directly</b> if they do not have children and are
9047 not attached to virtual machines in snapshots, and <b>indirectly</b>
9048 otherwise. Note that the smart attachment procedure is never performed
9049 for differencing hard disks.</li>
9050 <li><b>Immutable</b> hard disks are always attached <b>indirectly</b> because
9051 they are designed to be non-writable. If an immutable hard disk is
9052 attached to a virtual machine with snapshots then a special
9053 procedure called smart attachment is performed (see below).</li>
9054 <li><b>Writethrough</b> hard disks are always attached <b>directly</b>,
9055 also as designed. This also means that writethrough hard disks cannot
9056 have other hard disks linked to them at all.</li>
9057 </ul>
9058
9059 Note that the same hard disk, regardless of its type, may be attached to
9060 more than one virtual machine at a time. In this case, the machine that is
9061 started first gains exclusive access to the hard disk and attempts to
9062 start other machines having this hard disk attached will fail until the
9063 first machine is powered down.
9064
9065 Detaching hard disks is performed in a <i>deferred</i> fashion. This means
9066 that the given hard disk remains associated with the given machine after a
9067 successful <link to="IMachine::detachDevice"/> call until
9068 <link to="IMachine::saveSettings"/> is called to save all changes to
9069 machine settings to disk. This deferring is necessary to guarantee that
9070 the hard disk configuration may be restored at any time by a call to
9071 <link to="IMachine::discardSettings"/> before the settings
9072 are saved (committed).
9073
9074 Note that if <link to="IMachine::discardSettings"/> is called after
9075 indirectly attaching some hard disks to the machine but before a call to
9076 <link to="IMachine::saveSettings"/> is made, it will implicitly delete
9077 all differencing hard disks implicitly created by
9078 <link to="IMachine::attachDevice"/> for these indirect attachments.
9079 Such implicitly created hard disks will also be immediately deleted when
9080 detached explicitly using the <link to="IMachine::detachDevice"/>
9081 call if it is made before <link to="IMachine::saveSettings"/>. This
9082 implicit deletion is safe because newly created differencing hard
9083 disks do not contain any user data.
9084
9085 However, keep in mind that detaching differencing hard disks that were
9086 implicitly created by <link to="IMachine::attachDevice"/>
9087 before the last <link to="IMachine::saveSettings"/> call will
9088 <b>not</b> implicitly delete them as they may already contain some data
9089 (for example, as a result of virtual machine execution). If these hard
9090 disks are no more necessary, the caller can always delete them explicitly
9091 using <link to="#deleteStorage"/> after they are actually de-associated
9092 from this machine by the <link to="IMachine::saveSettings"/> call.
9093
9094 <h3>Smart Attachment</h3>
9095
9096 When normal base or immutable hard disks are indirectly attached to a
9097 virtual machine then some additional steps are performed to make sure the
9098 virtual machine will have the most recent "view" of the hard disk being
9099 attached. These steps include walking through the machine's snapshots
9100 starting from the current one and going through ancestors up to the first
9101 snapshot. Hard disks attached to the virtual machine in all
9102 of the encountered snapshots are checked whether they are descendants of
9103 the given normal base or immutable hard disk. The first found child (which
9104 is the differencing hard disk) will be used instead of the normal base or
9105 immutable hard disk as a parent for creating a new differencing hard disk
9106 that will be actually attached to the machine. And only if no descendants
9107 are found or if the virtual machine does not have any snapshots then the
9108 normal base or immutable hard disk will be used itself as a parent for
9109 this differencing hard disk.
9110
9111 It is easier to explain what smart attachment does using the
9112 following example:
9113 <pre>
9114BEFORE attaching B.vdi: AFTER attaching B.vdi:
9115
9116Snapshot 1 (B.vdi) Snapshot 1 (B.vdi)
9117 Snapshot 2 (D1->B.vdi) Snapshot 2 (D1->B.vdi)
9118 Snapshot 3 (D2->D1.vdi) Snapshot 3 (D2->D1.vdi)
9119 Snapshot 4 (none) Snapshot 4 (none)
9120 CurState (none) CurState (D3->D2.vdi)
9121
9122 NOT
9123 ...
9124 CurState (D3->B.vdi)
9125 </pre>
9126 The first column is the virtual machine configuration before the base hard
9127 disk <tt>B.vdi</tt> is attached, the second column shows the machine after
9128 this hard disk is attached. Constructs like <tt>D1->B.vdi</tt> and similar
9129 mean that the hard disk that is actually attached to the machine is a
9130 differencing hard disk, <tt>D1.vdi</tt>, which is linked to (based on)
9131 another hard disk, <tt>B.vdi</tt>.
9132
9133 As we can see from the example, the hard disk <tt>B.vdi</tt> was detached
9134 from the machine before taking Snapshot 4. Later, after Snapshot 4 was
9135 taken, the user decides to attach <tt>B.vdi</tt> again. <tt>B.vdi</tt> has
9136 dependent child hard disks (<tt>D1.vdi</tt>, <tt>D2.vdi</tt>), therefore
9137 it cannot be attached directly and needs an indirect attachment (i.e.
9138 implicit creation of a new differencing hard disk). Due to the smart
9139 attachment procedure, the new differencing hard disk
9140 (<tt>D3.vdi</tt>) will be based on <tt>D2.vdi</tt>, not on
9141 <tt>B.vdi</tt> itself, since <tt>D2.vdi</tt> is the most recent view of
9142 <tt>B.vdi</tt> existing for this snapshot branch of the given virtual
9143 machine.
9144
9145 Note that if there is more than one descendant hard disk of the given base
9146 hard disk found in a snapshot, and there is an exact device, channel and
9147 bus match, then this exact match will be used. Otherwise, the youngest
9148 descendant will be picked up.
9149
9150 There is one more important aspect of the smart attachment procedure which
9151 is not related to snapshots at all. Before walking through the snapshots
9152 as described above, the backup copy of the current list of hard disk
9153 attachment is searched for descendants. This backup copy is created when
9154 the hard disk configuration is changed for the first time after the last
9155 <link to="IMachine::saveSettings"/> call and used by
9156 <link to="IMachine::discardSettings"/> to undo the recent hard disk
9157 changes. When such a descendant is found in this backup copy, it will be
9158 simply re-attached back, without creating a new differencing hard disk for
9159 it. This optimization is necessary to make it possible to re-attach the
9160 base or immutable hard disk to a different bus, channel or device slot
9161 without losing the contents of the differencing hard disk actually
9162 attached to the machine in place of it.

9167 UUID of the medium. For a newly created medium, this value is a randomly

9170 <note>
9171 For media in one of MediumState_NotCreated, MediumState_Creating or

9188 (last known) value when <link to="#state"/> is <link

9215 Location of the storage unit holding medium data.
9216
9217 The format of the location string is medium type specific. For medium
9218 types using regular files in a host's file system, the location
9219 string is the full file name.
9220
9221 Some medium types may support changing the storage unit location by
9222 simply changing the value of this property. If this operation is not
9223 supported, the implementation will return E_NOTIMPL in attempt to set
9224 this attribute's value.
9225
9226 When setting a value of the location attribute which is a regular file
9227 in the host's file system, the given file name may be either relative to
9228 the <link to="IVirtualBox::homeFolder">VirtualBox home folder</link> or
9229 absolute. Note that if the given location specification does not contain
9230 the file extension part then a proper default extension will be

9241 where the full location specification is too long (such as lists
9242 and comboboxes in GUI frontends). This string is also used by frontends
9243 to sort the media list alphabetically when needed.
9244
9245 For example, for locations that are regular files in the host's file
9246 system, the value of this attribute is just the file name (+ extension),
9247 without the path specification.
9248
9249 Note that as opposed to the <link to="#location"/> attribute, the name

9337 Base medium of this medium.
9338
9339 If this is a differencing medium, its base medium is the medium
9340 the given medium branch starts from. For all other types of media, this
9341 property returns the medium object itself (i.e. the same object this

9349
9350 A medium is considered to be read-only when its contents cannot be
9351 modified without breaking the integrity of other parties that depend on
9352 this medium such as its child media or snapshots of virtual machines
9353 where this medium is attached to these machines. If there are no
9354 children and no such snapshots then there is no dependency and the
9355 medium is not read-only.
9356
9357 The value of this attribute can be used to determine the kind of the
9358 attachment that will take place when attaching this medium to a
9359 virtual machine. If the value is @c false then the medium will
9360 be attached directly. If the value is @c true then the medium
9361 will be attached indirectly by creating a new differencing child
9362 medium for that. See the interface description for more information.
9363
9364 Note that all <link to="MediumType_Immutable">Immutable</link> media

9451 <desc>
9452 If the current medium state (see <link to="MediumState"/>) is one of
9453 "Created", "Inaccessible" or "LockedRead", then this performs an
9454 accessibility check on the medium and sets the value of the <link to="#state"/>
9455 attribute accordingly; that value is also returned for convenience.
9456
9457 For all other state values, this does not perform a refresh but returns
9458 the state only.
9459
9460 The refresh, if performed, may take a long time (several seconds or even
9461 minutes, depending on the storage unit location and format) because it performs an
9462 accessibility check of the storage unit. This check may cause a significant
9463 delay if the storage unit of the given medium is, for example, a file located
9464 on a network share which is not currently accessible due to connectivity
9465 problems. In that case, the call will not return until a timeout
9466 interval defined by the host OS for this operation expires. For this reason,
9467 it is recommended to never read this attribute on the main UI thread to avoid
9468 making the UI unresponsive.
9469
9470 If the last known state of the medium is "Created" and the accessibility
9471 check fails, then the state would be set to "Inaccessible", and
9472 <link to="#lastAccessError"/> may be used to get more details about the
9473 failure. If the state of the medium is "LockedRead", then it remains the
9474 same, and a non-empty value of <link to="#lastAccessError"/> will
9475 indicate a failed accessibility check in this case.

9515 <method name="lockRead">
9516 <desc>
9517 Locks this medium for reading.
9518
9519 A read lock is shared: many clients can simultaneously lock the
9520 same medium for reading unless it is already locked for writing (see
9521 <link to="#lockWrite"/>) in which case an error is returned.
9522
9523 When the medium is locked for reading, it cannot be modified
9524 from within VirtualBox. This means that any method that changes
9525 the properties of this medium or contents of the storage unit
9526 will return an error (unless explicitly stated otherwise). That
9527 includes an attempt to start a virtual machine that wants to
9528 write to the the medium.
9529
9530 When the virtual machine is started up, it locks for reading all
9531 media it uses in read-only mode. If some medium cannot be locked
9532 for reading, the startup procedure will fail.
9533 A medium is typically locked for reading while it is used by a running
9534 virtual machine but has a depending differencing image that receives
9535 the actual write operations. This way one base medium can have
9536 multiple child differencing images which can be written to
9537 simultaneously. Read-only media such as DVD and floppy images are
9538 also locked for reading only (so they can be in use by multiple
9539 machines simultaneously).
9540
9541 A medium is also locked for reading when it is the source of a
9542 write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9543
9544 The medium locked for reading must be unlocked using the <link
9545 to="#unlockRead"/> method. Calls to <link to="#lockRead"/>
9546 can be nested and must be followed by the same number of paired
9547 <link to="#unlockRead"/> calls.
9548
9549 This method sets the medium state (see <link to="#state"/>) to
9550 "LockedRead" on success. The medium's previous state must be
9551 one of "Created", "Inaccessible" or "LockedRead".
9552
9553 Locking an inaccessible medium is not an error; this method performs
9554 a logical lock that prevents modifications of this medium through
9555 the VirtualBox API, not a physical file-system lock of the underlying
9556 storage unit.
9557
9558 This method returns the current state of the medium

9597 Locks this medium for writing.
9598
9599 A write lock, as opposed to <link to="#lockRead"/>, is
9600 exclusive: there may be only one client holding a write lock,
9601 and there may be no read locks while the write lock is held.
9602 As a result, read-locking fails if a write lock is held, and
9603 write-locking fails if either a read or another write lock is held.
9604
9605 When a medium is locked for writing, it cannot be modified
9606 from within VirtualBox, and it is not guaranteed that the values
9607 of its properties are up-to-date. Any method that changes the
9608 properties of this medium or contents of the storage unit will
9609 return an error (unless explicitly stated otherwise).
9610
9611 When a virtual machine is started up, it locks for writing all
9612 media it uses to write data to. If any medium could not be locked
9613 for writing, the startup procedure will fail. If a medium has
9614 differencing images, then while the machine is running, only
9615 the last ("leaf") differencing image is locked for writing,
9616 whereas its parents are locked for reading only.
9617
9618 A medium is also locked for writing when it is the target of a
9619 write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9620
9621 The medium locked for writing must be unlocked using the <link
9622 to="#unlockWrite"/> method. Write locks <i>cannot</i> be nested.
9623
9624 This method sets the medium state (see <link to="#state"/>) to
9625 "LockedWrite" on success. The medium's previous state must be
9626 either "Created" or "Inaccessible".
9627
9628 Locking an inaccessible medium is not an error; this method performs
9629 a logical lock that prevents modifications of this medium through
9630 the VirtualBox API, not a physical file-system lock of the underlying
9631 storage unit.

9944 <method name="mergeTo">
9945 <desc>
9946 Starts merging the contents of this medium and all intermediate
9947 differencing media in the chain to the given target medium.
9948
9949 The target medium must be either a descendant of this medium or
9950 its ancestor (otherwise this method will immediately return a failure).
9951 It follows that there are two logical directions of the merge operation:
9952 from ancestor to descendant (<i>forward merge</i>) and from descendant to
9953 ancestor (<i>backward merge</i>). Let us consider the following medium
9954 chain:
9955
9956 <pre>Base &lt;- Diff_1 &lt;- Diff_2</pre>
9957
9958 Here, calling this method on the <tt>Base</tt> medium object with
9959 <tt>Diff_2</tt> as an argument will be a forward merge; calling it on
9960 <tt>Diff_2</tt> with <tt>Base</tt> as an argument will be a backward
9961 merge. Note that in both cases the contents of the resulting medium
9962 will be the same, the only difference is the medium object that takes
9963 the result of the merge operation. In case of the forward merge in the
9964 above example, the result will be written to <tt>Diff_2</tt>; in case of
9965 the backward merge, the result will be written to <tt>Base</tt>. In
9966 other words, the result of the operation is always stored in the target
9967 medium.
9968
9969 Upon successful operation completion, the storage units of all media in
9970 the chain between this (source) medium and the target medium, including
9971 the source medium itself, will be automatically deleted and the
9972 relevant medium objects (including this medium) will become
9973 uninitialized. This means that any attempt to call any of
9974 their methods or attributes will fail with the
9975 <tt>"Object not ready" (E_ACCESSDENIED)</tt> error. Applied to the above
9976 example, the forward merge of <tt>Base</tt> to <tt>Diff_2</tt> will
9977 delete and uninitialize both <tt>Base</tt> and <tt>Diff_1</tt> media.
9978 Note that <tt>Diff_2</tt> in this case will become a base medium
9979 itself since it will no longer be based on any other medium.
9980
9981 Considering the above, all of the following conditions must be met in
9982 order for the merge operation to succeed:
9983 <ul>
9984 <li>
9985 Neither this (source) medium nor any intermediate
9986 differencing medium in the chain between it and the target
9987 medium is attached to any virtual machine.
9988 </li>
9989 <li>
9990 Neither the source medium nor the target medium is an
9991 <link to="MediumType_Immutable"/> medium.
9992 </li>
9993 <li>
9994 The part of the medium tree from the source medium to the
9995 target medium is a linear chain, i.e. all medium in this
9996 chain have exactly one child which is the next medium in this
9997 chain. The only exception from this rule is the target medium in
9998 the forward merge operation; it is allowed to have any number of
9999 child media because the merge operation will not change its
10000 logical contents (as it is seen by the guest OS or by children).
10001 </li>
10002 <li>
10003 None of the involved media are in
10004 <link to="MediumState_LockedRead"/> or
10005 <link to="MediumState_LockedWrite"/> state.
10006 </li>
10007 </ul>
10008
10009 <note>
10010 This (source) medium and all intermediates will be placed to <link
10011 to="MediumState_Deleting"/> state and the target medium will be

10028 Starts creating a clone of this medium in the format and at the

10030
10031 The target medium must be either in <link to="MediumState_NotCreated"/>
10032 state (i.e. must not have an existing storage unit) or in
10033 <link to="MediumState_Created"/> state (i.e. created and not locked, and
10034 big enough to hold the data or else the copy will be partial). Upon
10035 successful completion, the cloned medium will contain exactly the
10036 same sector data as the medium being cloned, except that in the
10037 first case a new UUID for the clone will be randomly generated, and in
10038 the second case the UUID will remain unchanged.
10039
10040 The @a parent argument defines which medium will be the parent
10041 of the clone. Passing a @c null reference indicates that the clone will
10042 be a base image, i.e. completely independent. It is possible to specify
10043 an arbitrary medium for this parameter, including the parent of the
10044 medium which is being cloned. Even cloning to a child of the source
10045 medium is possible. Note that when cloning to an existing image, the
10046 @a parent irgument is ignored.
10047
10048 After the returned progress object reports that the operation is

10108
10109 Resizing usually needs additional disk space, and possibly also
10110 some temporary disk space. Note that resize does not create a full

10257 The IMediumFormat interface represents a medium format.
10258
10259 Each medium format has an associated backend which is used to handle
10260 media stored in this format. This interface provides information
10261 about the properties of the associated backend.
10262
10263 Each medium format is identified by a string represented by the
10264 <link to="#id"/> attribute. This string is used in calls like
10265 <link to="IVirtualBox::createHardDisk"/> to specify the desired
10266 format.

10735
10736 There are two modes of working with the video buffer of the virtual
10737 machine. The <i>indirect</i> mode implies that the IFramebuffer
10738 implementation allocates a memory buffer for the requested display mode
10739 and provides it to the virtual machine. In <i>direct</i> mode, the
10740 IFramebuffer implementation uses the memory buffer allocated and owned
10741 by the virtual machine. This buffer represents the video memory of the
10742 emulated video adapter (so called <i>guest VRAM</i>). The direct mode is
10743 usually faster because the implementation gets a raw pointer to the
10744 guest VRAM buffer which it can directly use for visualizing the contents
10745 of the virtual display, as opposed to the indirect mode where the
10746 contents of guest VRAM are copied to the memory buffer provided by
10747 the implementation every time a display update occurs.
10748
10749 It is important to note that the direct mode is really fast only when
10750 the implementation uses the given guest VRAM buffer directly, for
10751 example, by blitting it to the window representing the virtual machine's
10752 display, which saves at least one copy operation comparing to the
10753 indirect mode. However, using the guest VRAM buffer directly is not
10754 always possible: the format and the color depth of this buffer may be
10755 not supported by the target window, or it may be unknown (opaque) as in
10756 case of text or non-linear multi-plane VGA video modes. In this case,
10757 the indirect mode (that is always available) should be used as a
10758 fallback: when the guest VRAM contents are copied to the
10759 implementation-provided memory buffer, color and format conversion is
10760 done automatically by the underlying code.
10761
10762 The @a pixelFormat parameter defines whether the direct mode is
10763 available or not. If @a pixelFormat is <link
10764 to="FramebufferPixelFormat_Opaque"/> then direct access to the guest
10765 VRAM buffer is not available -- the @a VRAM, @a bitsPerPixel and
10766 @a bytesPerLine parameters must be ignored and the implementation must use
10767 the indirect mode (where it provides its own buffer in one of the
10768 supported formats). In all other cases, @a pixelFormat together with
10769 @a bitsPerPixel and @a bytesPerLine define the format of the video memory
10770 buffer pointed to by the @a VRAM parameter and the implementation is
10771 free to choose which mode to use. To indicate that this frame buffer uses
10772 the direct mode, the implementation of the <link to="#usesGuestVRAM"/>
10773 attribute must return @c true and <link to="#address"/> must
10774 return exactly the same address that is passed in the @a VRAM parameter
10775 of this method; otherwise it is assumed that the indirect strategy is
10776 chosen.
10777
10778 The @a width and @a height parameters represent the size of the
10779 requested display mode in both modes. In case of indirect mode, the
10780 provided memory buffer should be big enough to store data of the given
10781 display mode. In case of direct mode, it is guaranteed that the given
10782 @a VRAM buffer contains enough space to represent the display mode of the
10783 given size. Note that this frame buffer's <link to="#width"/> and <link
10784 to="#height"/> attributes must return exactly the same values as
10785 passed to this method after the resize is completed (see below).
10786
10787 The @a finished output parameter determines if the implementation has
10788 finished resizing the frame buffer or not. If, for some reason, the
10789 resize cannot be finished immediately during this call, @a finished
10790 must be set to @c false, and the implementation must call
10791 <link to="IDisplay::resizeCompleted"/> after it has returned from
10792 this method as soon as possible. If @a finished is @c false, the
10793 machine will not call any frame buffer methods until
10794 <link to="IDisplay::resizeCompleted"/> is called.
10795
10796 Note that if the direct mode is chosen, the <link to="#bitsPerPixel"/>,
10797 <link to="#bytesPerLine"/> and <link to="#pixelFormat"/> attributes of
10798 this frame buffer must return exactly the same values as specified in the
10799 parameters of this method, after the resize is completed. If the
10800 indirect mode is chosen, these attributes must return values describing
10801 the format of the implementation's own memory buffer <link
10802 to="#address"/> points to. Note also that the <link to="#bitsPerPixel"/>
10803 value must always correlate with <link to="#pixelFormat"/>. Note that
10804 the <link to="#pixelFormat"/> attribute must never return <link
10805 to="FramebufferPixelFormat_Opaque"/> regardless of the selected mode.
10806
10807 <note>
10808 This method is called by the IDisplay object under the
10809 <link to="#lock"/> provided by this IFramebuffer
10810 implementation. If this method returns @c false in @a finished, then

11430 serial port hardware in one of two modes: host pipe or host device.
11431
11432 In host pipe mode, the #path attribute specifies the path to the pipe on
11433 the host computer that represents a serial port. The #server attribute
11434 determines if this pipe is created by the virtual machine process at
11435 machine startup or it must already exist before starting machine
11436 execution.
11437
11438 In host device mode, the #path attribute specifies the name of the
11439 serial port device on the host computer.
11440
11441 There is also a third communication mode: the disconnected mode. In this
11442 mode, the guest OS running inside the virtual machine will be able to
11443 detect the serial port, but all port write operations will be discarded
11444 and all port read operations will return no data.

11933 The IUSBDeviceFilter interface represents an USB device filter used
11934 to perform actions on a group of USB devices.
11935
11936 This type of filters is used by running virtual machines to
11937 automatically capture selected USB devices once they are physically
11938 attached to the host computer.
11939
11940 A USB device is matched to the given device filter if and only if all
11941 attributes of the device match the corresponding attributes of the
11942 filter (that is, attributes are joined together using the logical AND
11943 operation). On the other hand, all together, filters in the list of
11944 filters carry the semantics of the logical OR operation. So if it is
11945 desirable to create a match like "this vendor id OR this product id",
11946 one needs to create two filters and specify "any match" (see below)
11947 for unused attributes.
11948
11949 All filter attributes used for matching are strings. Each string
11950 is an expression representing a set of values of the corresponding
11951 device attribute, that will match the given filter. Currently, the
11952 following filtering expressions are supported:
11953
11954 <ul>
11955 <li><i>Interval filters</i>. Used to specify valid intervals for
11956 integer device attributes (Vendor ID, Product ID and Revision).
11957 The format of the string is:
11958
11959 <tt>int:((m)|([m]-[n]))(,(m)|([m]-[n]))*</tt>
11960
11961 where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
11962 (starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
11963 or decimal (otherwise) form, so that <tt>m &lt; n</tt>. If <tt>m</tt>
11964 is omitted before a dash (<tt>-</tt>), the minimum possible integer
11965 is assumed; if <tt>n</tt> is omitted after a dash, the maximum
11966 possible integer is assumed.
11967 </li>
11968 <li><i>Boolean filters</i>. Used to specify acceptable values for
11969 boolean device attributes. The format of the string is:
11970
11971 <tt>true|false|yes|no|0|1</tt>
11972
11973 </li>
11974 <li><i>Exact match</i>. Used to specify a single value for the given
11975 device attribute. Any string that doesn't start with <tt>int:</tt>
11976 represents the exact match. String device attributes are compared to
11977 this string including case of symbols. Integer attributes are first
11978 converted to a string (see individual filter attributes) and then
11979 compared ignoring case.
11980
11981 </li>
11982 <li><i>Any match</i>. Any value of the corresponding device attribute
11983 will match the given filter. An empty or @c null string is
11984 used to construct this type of filtering expressions.
11985
11986 </li>
11987 </ul>
11988
11989 <note>
11990 On the Windows host platform, interval filters are not currently
11991 available. Also all string filter attributes
11992 (<link to="#manufacturer"/>, <link to="#product"/>,
11993 <link to="#serialNumber"/>) are ignored, so they behave as
11994 <i>any match</i> no matter what string expression is specified.

12102 USB device state. This enumeration represents all possible states
12103 of the USB device physically attached to the host computer regarding
12104 its state on the host computer and availability to guest computers
12105 (all currently running virtual machines).
12106
12107 Once a supported USB device is attached to the host, global USB
12108 filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
12109 either ignore the device, or put it to USBDeviceState_Held state, or do
12110 nothing. Unless the device is ignored by global filters, filters of all
12111 currently running guests (<link to="IUSBController::deviceFilters"/>) are
12112 activated that can put it to USBDeviceState_Captured state.
12113
12114 If the device was ignored by global filters, or didn't match
12115 any filters at all (including guest ones), it is handled by the host
12116 in a normal way. In this case, the device state is determined by
12117 the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
12118 or USBDeviceState_Available, depending on the current device usage.
12119
12120 Besides auto-capturing based on filters, the device can be manually
12121 captured by guests (<link to="IConsole::attachUSBDevice"/>) if its
12122 state is USBDeviceState_Busy, USBDeviceState_Available or
12123 USBDeviceState_Held.
12124
12125 <note>
12126 Due to differences in USB stack implementations in Linux and Win32,
12127 states USBDeviceState_Busy and USBDeviceState_vailable are applicable
12128 only to the Linux version of the product. This also means that (<link
12129 to="IConsole::attachUSBDevice"/>) can only succeed on Win32 if the
12130 device state is USBDeviceState_Held.

12420 The ISharedFolder interface represents a folder in the host computer's
12421 file system accessible from the guest OS running inside a virtual
12422 machine using an associated logical name.
12423
12424 There are three types of shared folders:
12425 <ul>
12426 <li><i>Global</i> (<link to="IVirtualBox::sharedFolders"/>), shared
12427 folders available to all virtual machines.</li>
12428 <li><i>Permanent</i> (<link to="IMachine::sharedFolders"/>),
12429 VM-specific shared folders available to the given virtual machine at
12430 startup.</li>
12431 <li><i>Transient</i> (<link to="IConsole::sharedFolders"/>),
12432 VM-specific shared folders created in the session context (for
12433 example, when the virtual machine is running) and automatically
12434 discarded when the session is closed (the VM is powered off).</li>
12435 </ul>
12436
12437 Logical names of shared folders must be unique within the given scope
12438 (global, permanent or transient). However, they do not need to be unique
12439 across scopes. In this case, the definition of the shared folder in a
12440 more specific scope takes precedence over definitions in all other
12441 scopes. The order of precedence is (more specific to more general):
12442 <ol>
12443 <li>Transient definitions</li>
12444 <li>Permanent definitions</li>
12445 <li>Global definitions</li>
12446 </ol>
12447
12448 For example, if MyMachine has a shared folder named
12449 <tt>C_DRIVE</tt> (that points to <tt>C:\\</tt>), then creating a
12450 transient shared folder named <tt>C_DRIVE</tt> (that points
12451 to <tt>C:\\\\WINDOWS</tt>) will change the definition
12452 of <tt>C_DRIVE</tt> in the guest OS so
12453 that <tt>\\\\VBOXSVR\\C_DRIVE</tt> will give access
12454 to <tt>C:\\WINDOWS</tt> instead of <tt>C:\\</tt> on the host
12455 PC. Removing the transient shared folder <tt>C_DRIVE</tt> will restore
12456 the previous (permanent) definition of <tt>C_DRIVE</tt> that points
12457 to <tt>C:\\</tt> if it still exists.
12458
12459 Note that permanent and transient shared folders of different machines
12460 are in different name spaces, so they don't overlap and don't need to
12461 have unique logical names.
12462
12463 <note>
12464 Global shared folders are not implemented in the current version of the
12465 product.

12871 The ISession interface represents a serialization primitive for virtual
12872 machines.
12873
12874 With VirtualBox, every time one wishes to manipulate a virtual machine
12875 (e.g. change its settings or start execution), a session object is
12876 required. Such an object must be passed to one of the session methods
12877 that open the given session, which then initiates the machine manipulation.
12878
12879 A session serves several purposes: it identifies to the inter-process VirtualBox
12880 code which process is currently working with the virtual machine, and it ensures
12881 that there are no incompatible requests from several processes for the
12882 same virtual machine. Session objects can therefore be thought of as mutex
12883 semaphores that lock virtual machines to prevent conflicting accesses from
12884 several processes.
12885
12886 How sessions objects are used depends on whether you use the Main API
12887 via COM or via the webservice:
12888
12889 <ul>
12890 <li>When using the COM API directly, an object of the Session class from the
12891 VirtualBox type library needs to be created. In regular COM C++ client code,
12892 this can be done by calling <tt>createLocalObject()</tt>, a standard COM API.
12893 This object will then act as a local session object in further calls to open
12894 a session.
12895 </li>
12896
12897 <li>In the webservice, the session manager (IWebsessionManager) instead creates
12898 one session object automatically when <link to="IWebsessionManager::logon" />
12899 is called. A managed object reference to that session object can be retrieved by
12900 calling <link to="IWebsessionManager::getSessionObject" />. This session object
12901 reference can then be used to open sessions.
12902 </li>
12903 </ul>
12904
12905 Sessions are mainly used in two variations:
12906
12907 <ul>
12908 <li>
12909 To start a virtual machine in a separate process, one would call
12910 <link to="IVirtualBox::openRemoteSession"/>, which requires a session
12911 object as its first parameter. This session then identifies the caller
12912 and lets him control the started machine (for example, pause machine
12913 execution or power it down) as well as be notified about machine
12914 execution state changes.
12915 </li>
12916
12917 <li>To alter machine settings, or to start machine execution within the
12918 current process, one needs to open a direct session for the machine first by
12919 calling <link to="IVirtualBox::openSession"/>. While a direct session
12920 is open within one process, no any other process may open another direct
12921 session for the same machine. This prevents the machine from being changed
12922 by other processes while it is running or while the machine is being configured.
12923 </li>
12924 </ul>
12925
12926 One also can attach to an existing direct session already opened by
12927 another process (for example, in order to send a control request to the
12928 virtual machine such as the pause or the reset request). This is done by
12929 calling <link to="IVirtualBox::openExistingSession"/>.
12930
12931 <note>
12932 Unless you are trying to write a new VirtualBox front-end that
12933 performs direct machine execution (like the VirtualBox or VBoxSDL
12934 front-ends), don't call <link to="IConsole::powerUp"/> in a direct
12935 session opened by <link to="IVirtualBox::openSession"/> and use this
12936 session only to change virtual machine settings. If you simply want to
12937 start virtual machine execution using one of the existing front-ends
12938 (for example the VirtualBox GUI or headless server), simply use
12939 <link to="IVirtualBox::openRemoteSession"/>; these front-ends
12940 will power up the machine automatically for you.

12964 <method name="close">
12965 <desc>
12966 Closes a session that was previously opened.
12967
12968 It is recommended that every time an "open session" method (such as
12969 <link to="IVirtualBox::openRemoteSession" /> or
12970 <link to="IVirtualBox::openSession" />) has been called to
12971 manipulate a virtual machine, the caller invoke
12972 ISession::close() when it's done doing so. Since sessions are
12973 serialization primitives much like ordinary mutexes, they are
12974 best used the same way: for each "open" call, there should be
12975 a matching "close" call, even when errors occur.
12976
12977 Otherwise, if a direct session for a machine opened with
12978 <link to="IVirtualBox::openSession"/> is not explicitly closed
12979 when the application terminates, the state of the machine will
12980 be set to <link to="MachineState_Aborted" /> on the server.
12981
12982 Generally, it is recommended to close all open sessions explicitly
12983 before terminating the application (regardless of the reason for
12984 the termination).
12985
12986 <note>
12987 Do not expect the session state (<link to="ISession::state" />
12988 to return to "Closed" immediately after you invoke
12989 ISession::close(), particularly if you have started a remote
12990 session to execute the VM in a new process. The session state will
12991 automatically return to "Closed" once the VM is no longer executing,
12992 which can of course take a very long time.

13067 Represents a storage controller that is attached to a virtual machine
13068 (<link to="IMachine" />). Just as drives (hard disks, DVDs, FDs) are
13069 attached to storage controllers in a real computer, virtual drives
13070 (represented by <link to="IMediumAttachment" />) are attached to virtual
13071 storage controllers, represented by this interface.
13072
13073 As opposed to physical hardware, VirtualBox has a very generic concept
13074 of a storage controller, and for purposes of the Main API, all virtual
13075 storage is attached to virtual machines via instances of this interface.
13076 There are four types of such virtual storage controllers: IDE, SCSI, SATA
13077 and Floppy (see <link to="#bus" />). Depending on which of these four is
13078 used, certain sub-types may be available and can be selected in
13079 <link to="#controllerType" />.
13080
13081 Depending on these settings, the guest operating system might see

13198 Managed object reference.
13199
13200 Only within the webservice, a managed object reference (which is really
13201 an opaque number) allows a webservice client to address an object
13202 that lives in the address space of the webservice server.
13203
13204 Behind each managed object reference, there is a COM object that lives
13205 in the webservice server's address space. The COM object is not freed
13206 until the managed object reference is released, either by an explicit
13207 call to <link to="IManagedObjectRef::release" /> or by logging off from
13208 the webservice (<link to="IWebsessionManager::logoff" />), which releases
13209 all objects created during the webservice session.
13210
13211 Whenever a method call of the VirtualBox API returns a COM object, the
13212 webservice representation of that method will instead return a

13360 The IPerformanceCollector interface represents a service that collects and
13361 stores performance metrics data.
13362
13363 Performance metrics are associated with objects of interfaces like IHost and
13364 IMachine. Each object has a distinct set of performance metrics.
13365 The set can be obtained with <link to="IPerformanceCollector::getMetrics"/>.
13366
13367 Metric data is collected at the specified intervals and is retained
13368 internally. The interval and the number of retained samples can be set
13369 with <link to="IPerformanceCollector::setupMetrics" />.
13370
13371 Metrics are organized hierarchically, with each level separated by a
13372 slash (/) character. Generally, the scheme for metric names is like this:
13373
13374 <tt>Category/Metric[/SubMetric][:aggregation]</tt>
13375
13376 "Category/Metric" together form the base metric name. A base metric is the
13377 smallest unit for which a sampling interval and the number of retained
13378 samples can be set. Only base metrics can be enabled and disabled. All
13379 sub-metrics are collected when their base metric is collected.
13380 Collected values for any set of sub-metrics can be queried with
13381 <link to="IPerformanceCollector::queryMetricsData" />.
13382
13383 For example "CPU/Load/User:avg"
13384 metric name stands for the "CPU" category, "Load" metric, "User" submetric,
13385 "average" aggregate. An aggregate function is computed over all retained
13386 data. Valid aggregate functions are:
13387
13388 <ul>
13389 <li>avg -- average</li>
13390 <li>min -- minimum</li>
13391 <li>max -- maximum</li>
13392 </ul>
13393
13394 When setting up
13395 metric parameters, querying metric data, enabling or disabling metrics
13396 wildcards can be used in metric names to specify a subset of metrics. For
13397 example, to select all CPU-related metrics use <tt>CPU/*</tt>, all
13398 averages can be queried using <tt>*:avg</tt> and so on. To query metric
13399 values without aggregates <tt>*:</tt> can be used.
13400
13401 The valid names for base metrics are:
13402
13403 <ul>
13404 <li>CPU/Load</li>
13405 <li>CPU/MHz</li>
13406 <li>RAM/Usage</li>
13407 </ul>
13408
13409 The general sequence for collecting and retrieving the metrics is:
13410 <ul>
13411 <li>
13412 Obtain an instance of IPerformanceCollector with
13413 <link to="IVirtualBox::performanceCollector" />
13414 </li>
13415 <li>
13416 Allocate and populate an array with references to objects the metrics
13417 will be collected for. Use references to IHost and IMachine objects.
13418 </li>
13419 <li>
13420 Allocate and populate an array with base metric names the data will be
13421 collected for.
13422 </li>
13423 <li>
13424 Call <link to="IPerformanceCollector::setupMetrics" />. From now on the
13425 metric data will be collected and stored.
13426 </li>
13427 <li>
13428 Wait for the data to get collected.
13429 </li>
13430 <li>
13431 Allocate and populate an array with references to objects the metric
13432 values will be queried for. You can re-use the object array used for
13433 setting base metrics.
13434 </li>
13435 <li>
13436 Allocate and populate an array with metric names the data will be
13437 collected for. Note that metric names differ from base metric names.
13438 </li>
13439 <li>
13440 Call <link to="IPerformanceCollector::queryMetricsData" />. The data that
13441 have been collected so far are returned. Note that the values are still
13442 retained internally and data collection continues.

13600 <desc>
13601 Queries collected metrics data for a set of objects.
13602
13603 The data itself and related metric information are returned in seven
13604 parallel and one flattened array of arrays. Elements of
13605 <tt>returnMetricNames, returnObjects, returnUnits, returnScales,
13606 returnSequenceNumbers, returnDataIndices and returnDataLengths</tt> with
13607 the same index describe one set of values corresponding to a single
13608 metric.
13609
13610 The <tt>returnData</tt> parameter is a flattened array of arrays. Each
13611 start and length of a sub-array is indicated by
13612 <tt>returnDataIndices</tt> and <tt>returnDataLengths</tt>. The first
13613 value for metric <tt>metricNames[i]</tt> is at
13614 <tt>returnData[returnIndices[i]]</tt>.
13615
13616 <note>
13617 @c Null or empty metric name array means all metrics. @c Null or empty
13618 object array means all existing objects. If metric name array contains
13619 a single element and object array contains many, the single metric
13620 name array element is applied to each object array element to form
13621 metric/object pairs.
13622 </note>
13623 <note>
13624 Data collection continues behind the scenes after call to
13625 @c queryMetricsData. The return data can be seen as the snapshot of
13626 the current state at the time of @c queryMetricsData call. The
13627 internally kept metric values are not cleared by the call. This makes
13628 possible querying different subsets of metrics or aggregates with
13629 subsequent calls. If periodic querying is needed it is highly
13630 suggested to query the values with @c interval*count period to avoid
13631 confusion. This way a completely new set of data values will be
13632 provided by each query.
