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>

478	Virtual machine execution state.
479
480	This enumeration represents possible values of the <link
481	to="IMachine::state"/> attribute.
482
483	Below is the basic virtual machine state diagram. It shows how the state
484	changes during virtual machine execution. The text in square braces shows
485	a method of the IConsole interface that performs the given state
486	transition.

502	\| \| \|
503	+-------------- Stopping -------[powerDown()]<----------+---------------------+
504	</pre>
505
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() >= MachineState_FirstOnline &&
517	machine.GetState() <= 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	+-> PoweredOff --+ \|
557	\| \| \|
558	\|-> Aborted -----+-->[lengthy VM configuration call] --> SettingUp -----+
559	\| \|
560	+-> 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	+-> PoweredOff --+ \|
571	\| +-->[takeSnapshot()] -------------------> Saving ------+
572	+-> Aborted -----+
573
574	+-> PoweredOff --+
575	\| \|
576	\| Aborted -----+-->[restoreSnapshot() ]-------> RestoringSnapshot -+
577	\| \| [deleteSnapshot() ]-------> DeletingSnapshot --+
578	+-> 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 <= state <= LastOnline</tt> must be
596	@c true. The same relates to transient states for which
597	the condition <tt>FirstOnline <= state <= LastOnline</tt> must be
598	@c true.

1119	name="IVirtualBoxErrorInfo" extends="$errorinfo"
1120	uuid="4b86d186-407e-4f9e-8be8-e50061be8725"

1122	wsmap="managed"
1123	>
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).

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.

1592	The IVirtualBox interface represents the main interface exposed by the
1593	product that provides virtual machine management.
1594
1595	An instance of IVirtualBox is required for the product to do anything
1596	useful. Even though the interface does not expose this, internally,
1597	IVirtualBox is implemented as a singleton and actually lives in the
1598	process of the VirtualBox server (VBoxSVC.exe). This makes sure that
1599	IVirtualBox can track the state of all virtual machines on a particular
1600	host, regardless of which frontend started them.
1601

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	<base_folder>/<machine_name>/<machine_name>.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.

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.
2097
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.
2114
2115	Note that the format of the location string is storage format specific.

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

2649
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.

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.<UUID>.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

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

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=<index>;channel=<c>"
3517	In this string, <index> 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, <c> 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=<X>" format, where <X> 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" />.

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.

4189	inaccessibility.
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.

4198	<attribute name="name" type="wstring">
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.

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

5778	This interface is used by a client of the Main API that need to
5779	be notified of events. For example, a graphical user interface
5780	can use this to learn about machine state changes so they can
5781	update the list of virtual machines without having to rely
5782	on polling.
5783
5784	Whenever relevant events occur in VirtualBox, the callbacks in
5785	objects of this interface are called. In order for this to be
5786	useful, a client needs to create its own subclass that implements
5787	this interface in which the methods for the relevant callbacks
5788	are overridden. An instance of this subclass interface can then
5789	be passed to <link to="IConsole::registerCallback" />.

5831	The @a shape buffer contains a 1-bpp (bits per pixel) AND mask
5832	followed by a 32-bpp XOR (color) mask.
5833
5834	For pointers without alpha channel the XOR mask pixels are 32
5835	bit values: (lsb)BGR0(msb). For pointers with alpha channel
5836	the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
5837
5838	An AND mask is used for pointers with alpha channel, so if the
5839	callback does not support alpha, the pointer could be
5840	displayed as a normal color pointer.
5841
5842	The AND mask is a 1-bpp bitmap with byte aligned scanlines. The
5843	size of the AND mask therefore is <tt>cbAnd = (width + 7) / 8 *
5844	height</tt>. The padding bits at the end of each scanline are
5845	undefined.
5846
5847	The XOR mask follows the AND mask on the next 4-byte aligned
5848	offset: <tt>uint8_t *pXor = pAnd + (cbAnd + 3) & ~3</tt>.
5849	Bytes in the gap between the AND and the XOR mask are undefined.
5850	The XOR mask scanlines have no gap between them and the size of
5851	the XOR mask is: <tt>cXor = width * 4 * height</tt>.

6032	<desc>
6033	Notification when an error happens during the virtual
6034	machine execution.
6035
6036	There are three kinds of runtime errors:
6037	<ul>
6038	<li><i>fatal</i></li>
6039	<li><i>non-fatal with retry</i></li>
6040	<li><i>non-fatal warnings</i></li>
6041	</ul>
6042
6043	<b>Fatal</b> errors are indicated by the @a fatal parameter set
6044	to @c true. In case of fatal errors, the virtual machine
6045	execution is always paused before calling this notification, and
6046	the notification handler is supposed either to immediately save
6047	the virtual machine state using <link to="IConsole::saveState"/>
6048	or power it off using <link to="IConsole::powerDown"/>.
6049	Resuming the execution can lead to unpredictable results.
6050
6051	<b>Non-fatal</b> errors and warnings are indicated by the
6052	@a fatal parameter set to @c false. If the virtual machine
6053	is in the Paused state by the time the error notification is
6054	received, it means that the user can <i>try to resume</i> the machine
6055	execution after attempting to solve the problem that caused the
6056	error. In this case, the notification handler is supposed
6057	to show an appropriate message to the user (depending on the
6058	value of the @a id parameter) that offers several actions such
6059	as <i>Retry</i>, <i>Save</i> or <i>Power Off</i>. If the user
6060	wants to retry, the notification handler should continue
6061	the machine execution using the <link to="IConsole::resume"/>
6062	call. If the machine execution is not Paused during this
6063	notification, then it means this notification is a <i>warning</i>
6064	(for example, about a fatal condition that can happen very soon);
6065	no immediate action is required from the user, the machine
6066	continues its normal execution.
6067
6068	Note that in either case the notification handler
6069	<b>must not</b> perform any action directly on a thread
6070	where this notification is called. Everything it is allowed to
6071	do is to post a message to another thread that will then talk
6072	to the user and take the corresponding action.
6073
6074	Currently, the following error identifiers are known:
6075	<ul>
6076	<li><tt>"HostMemoryLow"</tt></li>
6077	<li><tt>"HostAudioNotResponding"</tt></li>
6078	<li><tt>"VDIStorageFull"</tt></li>

6145	that it may be impossible to activate a window without the
6146	help of the currently active application (which is supposedly
6147	an initiator of this notification). In this case, this method
6148	must return a non-zero identifier that represents the
6149	top-level window of the VM console process. The caller, if it
6150	represents a currently active process, is responsible to use
6151	this identifier (in a platform-dependent manner) to perform
6152	actual window activation.
6153
6154	This method must set @a winId to zero if it has performed all
6155	actions necessary to complete the request and the console
6156	window is now active and in foreground, to indicate that no

6844	<method name="deleteSnapshot">
6845	<desc>
6846	Starts discarding the specified snapshot asynchronously.
6847	See <link to="ISnapshot" /> for an introduction to snapshots.
6848
6849	The execution state and settings of the associated machine stored in
6850	the snapshot will be deleted. The contents of all differencing media of
6851	this snapshot will be merged with the contents of their dependent child
6852	media to keep the medium chain valid (in other words, all changes
6853	represented by media being discarded will be propagated to their child
6854	medium). After that, this snapshot's differencing medium will be
6855	deleted. The parent of this snapshot will become a new parent for all
6856	its child snapshots.
6857
6858	If the discarded snapshot is the current one, its parent
6859	snapshot will become a new current snapshot. The current machine
6860	state is not directly affected in this case, except that
6861	currently attached differencing media based on media
6862	of the discarded snapshot will be also merged as described
6863	above.
6864
6865	If the discarded snapshot is the first one (the root snapshot)
6866	and it has exactly one child snapshot, this child snapshot will
6867	become the first snapshot after discarding. If there are no
6868	children at all (i.e. the first snapshot is the only snapshot of
6869	the machine), both the current and the first snapshot of the
6870	machine will be set to @c null. In all other cases, the first
6871	snapshot cannot be discarded.
6872
6873	You cannot discard the snapshot if it
6874	stores <link to="MediumType_Normal">normal</link> (non-differencing)
6875	media that have differencing media based on them. Snapshots of
6876	such kind can be discarded only when every normal medium has either
6877	no children at all or exactly one child. In the former case, the normal
6878	medium simply becomes unused (i.e. not attached to any VM). In the
6879	latter case, it receives all the changes stored in the child medium,
6880	and then it replaces the child medium in the configuration of the
6881	corresponding snapshot or machine.
6882
6883	Also, you cannot discard the snapshot if it stores media
6884	(of any type) having differencing child media that belong
6885	to other machines. Such snapshots can be only discarded after
6886	you discard all snapshots of other machines containing "foreign"
6887	child media, or detach these "foreign" child media from machines
6888	they are attached to.
6889
6890	One particular example of the snapshot storing normal media
6891	is the first snapshot of a virtual machine that had normal media
6892	attached when taking the snapshot. Be careful when
6893	discarding such snapshots because this implicitly commits
6894	changes (made since the snapshot being discarded has been taken)
6895	to normal media (as described above), which may be not what
6896	you want.
6897
6898	The virtual machine is put to
6899	the <link to="MachineState_Discarding">Discarding</link> state until
6900	the discard operation is completed.
6901
6902	<note>
6903	The machine must not be running, otherwise the operation
6904	will fail.
6905	</note>
6906
6907	<note>
6908	Child media of all normal media of the discarded snapshot
6909	must be accessible (see <link to="IMedium::state"/>) for this
6910	operation to succeed. In particular, this means that all virtual
6911	machines, whose media are directly or indirectly based on the
6912	media of discarded snapshot, must be powered off.
6913	</note>
6914	<note>
6915	Merging medium contents can be very time and disk space
6916	consuming, if these media are big in size and have many
6917	children. However, if the snapshot being discarded is the last
6918	(head) snapshot on the branch, the operation will be rather
6919	quick.
6920	</note>
6921	<note>
6922	Note that discarding the current snapshot
6923	will implicitly call <link to="IMachine::saveSettings"/> to
6924	make all current machine settings permanent.

7790	<link to="IVirtualBox::createHardDisk"/> to refer to a particular

7797	refer to the same medium format.

7814	when the medium format was not specified explicitly. One example is
7815	<link to="IVirtualBox::createHardDisk"/> with the empty
7816	format argument. A more complex example is implicit creation of
7817	differencing media when taking a snapshot of a virtual machine:
7818	this operation will try to use a format of the parent medium first
7819	and if this format does not support differencing media the default
7820	format specified by this argument will be used.
7821
7822	The list of supported medium formats may be obtained by the
7823	<link to="#mediaFormats"/> call. Note that the default medium
7824	format must have a capability to create differencing media;
7825	otherwise operations that create media implicitly may fail

7873
7874	As opposed to <link to="ISystemProperties::remoteDisplayAuthLibrary" />,
7875	there is no per-VM setting for this, as the webservice is a global
7876	resource (if it is running). Only for this setting (for the webservice),
7877	setting this value to a literal <tt>"null"</tt> string disables authentication,
7878	meaning that <link to="IWebsessionManager::logon" /> will always succeed,
7879	no matter what user name and password are supplied.
7880
7881	The initial value of this property is <tt>"VRDPAuth"</tt>,
7882	meaning that the webservice will use the same authentication
7883	library that is used by default for VBoxVRDP (again, see
7884	<link to="ISystemProperties::remoteDisplayAuthLibrary" />).
7885	The format and calling convention of authentication libraries

8161	<desc>
8162	The IProgress interface is used to track and control
8163	asynchronous tasks within VirtualBox.
8164
8165	An instance of this is returned every time VirtualBox starts
8166	an asynchronous task (in other words, a separate thread) which
8167	continues to run after a method call returns. For example,
8168	<link to="IConsole::saveState" />, which saves the state of
8169	a running virtual machine, can take a long time to complete.
8170	To be able to display a progress bar, a user interface such as
8171	the VirtualBox graphical user interface can use the IProgress
8172	object returned by that method.
8173
8174	Note that IProgress is a "read-only" interface in the sense
8175	that only the VirtualBox internals behind the Main API can
8176	create and manipulate progress objects, whereas client code
8177	can only use the IProgress object to monitor a task's
8178	progress and, if <link to="#cancelable" /> is @c true,
8179	cancel the task by calling <link to="#cancel" />.
8180
8181	A task represented by IProgress consists of either one or
8182	several sub-operations that run sequentially, one by one (see
8183	<link to="#operation" /> and <link to="#operationCount" />).
8184	Every operation is identified by a number (starting from 0)
8185	and has a separate description.
8186
8187	You can find the individual percentage of completion of the current
8188	operation in <link to="#operationPercent" /> and the
8189	percentage of completion of the task as a whole
8190	in <link to="#percent" />.
8191
8192	Similarly, you can wait for the completion of a particular
8193	operation via <link to="#waitForOperationCompletion" /> or

8195	<link to="#waitForCompletion" />.

8375	media and saving the VM settings and (if the VM is running)
8376	the current VM state in the snapshot.
8377
8378	The differencing images will then receive all data written to
8379	the machine's media, while their parent (base) images
8380	remain unmodified after the snapshot has been taken (see
8381	<link to="IMedium" /> for details about differencing images).
8382	This simplifies restoring a machine to the state of a snapshot:
8383	only the differencing images need to be deleted.
8384
8385	The current machine state is not changed by taking a snapshot.
8386	If the machine is running, it will resume execution after the
8387	snapshot has been taken.
8388	</li>
8389
8390	<li><link to="IConsole::restoreSnapshot"/>: this goes back to
8391	a previous snapshot. This resets the machine's state to that of
8392	the previous snapshot by deleting the differencing image of each
8393	of the machine's media and setting the machine's settings
8394	and state to the state that was saved in the snapshot (if any).
8395
8396	This destroys the machine's current state.
8397	</li>
8398
8399	<li><link to="IConsole::deleteSnapshot"/>: deletes a snapshot
8400	without affecting the current machine state.
8401
8402	This does not change the machine, but instead frees the resources
8403	allocated when the snapshot was taken: the settings and machine state
8404	is deleted (if any), and the snapshot's differencing image for each
8405	of the machine's media gets merged with its parent image.
8406
8407	Neither the current machine state nor other snapshots are affected
8408	by this operation, except that parent media will be modified
8409	to contain the disk data associated with the snapshot being deleted.
8410	</li>
8411	</ul>
8412
8413	Each snapshot contains the settings of the virtual machine (hardware
8414	configuration etc.). In addition, if the machine was running when the
8415	snapshot was taken (<link to="IMachine::state"/> is <link to="MachineState_Running"/>),
8416	the current VM state is saved in the snapshot (similarly to what happens
8417	when a VM's state is saved). The snapshot is then said to
8418	be <i>online</i> because when restoring it, the VM will be running.
8419
8420	If the machine is saved (<link to="MachineState_Saved"/>), the snapshot
8421	receives a copy of the execution state file (<link to="IMachine::stateFilePath"/>).
8422
8423	Otherwise, if the machine was not running (<link to="MachineState_PoweredOff"/>
8424	or <link to="MachineState_Aborted"/>), the snapshot is <i>offline</i>;
8425	it then contains a so-called "zero execution state", representing a
8426	machine that is powered off.
8427
8428	<h3>Snapshot branches and the "current" snapshot</h3>
8429
8430	Snapshots can be chained, whereby every next snapshot is based on the
8431	previous one. This chaining is related to medium branching
8432	(see the <link to="IMedium"/> description) in that every time
8433	a new snapshot is created, a new differencing medium is implicitly
8434	created for all normal media attached to the machine.
8435
8436	Each virtual machine has a "current snapshot", identified by
8437	<link to="IMachine::currentSnapshot"/>. Presently, this is always set
8438	to the last snapshot in the chain. In a future version of VirtualBox,
8439	it will be possible to reset a machine's current state to that of an
8440	earlier snapshot without discarding the current state so that it will be
8441	possible to create alternative snapshot paths in a snapshot tree.
8442
8443	In the current implementation, multiple snapshot branches within one
8444	virtual machine are not allowed. Every machine has a single branch,
8445	and <link to="IConsole::takeSnapshot"/> operation adds a new
8446	snapshot to the top of that branch.

8690	<desc>
8691	The IMedium interface represents virtual storage for a machine's
8692	hard disks, CD/DVD or floppy drives. It will typically represent
8693	a disk image on the host, for example a VDI or VMDK file representing
8694	a virtual hard disk, or an ISO or RAW file representing virtual
8695	removable media, but can also point to a network location (e.g.
8696	for iSCSI targets).
8697
8698	Instances of IMedium are connected to virtual machines by way of
8699	medium attachments (see <link to="IMediumAttachment" />), which link
8700	the storage medium to a particular device slot of a storage controller
8701	of the virtual machine.
8702	In the VirtualBox API, virtual storage is therefore always represented
8703	by the following chain of object links:
8704
8705	<ul>
8706	<li><link to="IMachine::storageControllers"/> contains an array of
8707	storage controllers (IDE, SATA, SCSI or a floppy controller;
8708	these are instances of <link to="IStorageController"/>).</li>
8709	<li><link to="IMachine::mediumAttachments"/> contains an array of
8710	medium attachments (instances of <link to="IMediumAttachment"/>),
8711	each containing a storage controller from the above array, a
8712	port/device specification, and an instance of IMedium representing
8713	the medium storage (image file).
8714
8715	For removable media, the storage medium is optional; a medium
8716	attachment with no medium represents a CD/DVD or floppy drive
8717	with no medium inserted. By contrast, hard disk attachments
8718	will always have an IMedium object attached.</li>
8719	<li>Each IMedium in turn points to a storage unit (such as a file
8720	on the host computer or a network resource) that holds actual
8721	data. This location is represented by the <link to="#location"/>
8722	attribute.</li>
8723	</ul>
8724
8725	Existing media are opened using the following methods, depending on the
8726	media type:
8727	<ul>
8728	<li><link to="IVirtualBox::openHardDisk"/></li>
8729	<li><link to="IVirtualBox::openDVDImage"/></li>
8730	<li><link to="IVirtualBox::openFloppyImage"/></li>
8731	</ul>
8732
8733	New hard disk media can be created with the VirtualBox API using the
8734	<link to="IVirtualBox::createHardDisk"/> method.
8735
8736	CD/DVD and floppy images (ISO and RAW files) are usually created outside
8737	VirtualBox, e.g. by storing a copy of the real medium of the corresponding
8738	type in a regular file.
8739
8740	Only for CD/DVDs and floppies, an IMedium instance can also represent a host
8741	drive; in that case the <link to="#id" /> attribute contains the UUID of
8742	one of the drives in <link to="IHost::DVDDrives" /> or <link to="IHost::floppyDrives" />.
8743
8744	<h3>Known media</h3>
8745
8746	When an existing medium is opened for the first time, it is automatically
8747	remembered by the given VirtualBox installation or, in other words, becomes
8748	a <i>known medium</i>. Known media are stored in the media
8749	registry transparently maintained by VirtualBox and stored in settings
8750	files so that this registry is preserved when VirtualBox is not running.
8751
8752	Newly created virtual media are remembered only when the associated
8753	storage unit is actually created.
8754
8755	All known media can be enumerated using
8756	<link to="IVirtualBox::hardDisks"/>,
8757	<link to="IVirtualBox::DVDImages"/> and
8758	<link to="IVirtualBox::floppyImages"/> attributes. Individual media can be
8759	quickly found by UUID using <link to="IVirtualBox::getHardDisk"/>
8760	and similar methods or by location using
8761	<link to="IVirtualBox::findHardDisk"/> and similar methods.
8762
8763	Only known media can be attached to virtual machines.
8764
8765	Removing known media from the media registry is performed when the given
8766	medium is closed using the <link to="#close"/> method or when its
8767	associated storage unit is deleted.
8768
8769	<h3>Accessibility checks</h3>
8770
8771	VirtualBox defers media accessibility checks until the <link to="#refreshState" />
8772	method is called explicitly on a medium. This is done to make the VirtualBox object
8773	ready for serving requests as fast as possible and let the end-user
8774	application decide if it needs to check media accessibility right away or not.
8775
8776	As a result, when VirtualBox starts up (e.g. the VirtualBox
8777	object gets created for the first time), all known media are in the
8778	"Inaccessible" state, but the value of the <link to="#lastAccessError"/>
8779	attribute is an empty string because no actual accessibility check has
8780	been made yet.
8781
8782	After calling <link to="#refreshState" />, a medium is considered
8783	<i>accessible</i> if its storage unit can be read. In that case, the
8784	<link to="#state"/> attribute has a value of "Created". If the storage
8785	unit cannot be read (for example, because it is located on a disconnected
8786	network resource, or was accidentally deleted outside VirtualBox),
8787	the medium is considered <i>inaccessible</i>, which is indicated by the
8788	"Inaccessible" state. The exact reason why the medium is inaccessible can be
8789	obtained by reading the <link to="#lastAccessError"/> attribute.
8790
8791	<h3>Medium types</h3>
8792
8793	There are three types of medium behavior (see <link to="MediumType" />):
8794	"normal", "immutable" and "writethrough", represented by the
8795	<link to="#type"/> attribute. The type of the medium defines how the
8796	medium is attached to a virtual machine and what happens when a
8797	<link to="ISnapshot">snapshot</link> of the virtual machine with the
8798	attached medium is taken. At the moment DVD and floppy media are always
8799	of type "writethrough".
8800
8801	All media can be also divided in two groups: <i>base</i> media and
8802	<i>differencing</i> media. A base medium contains all sectors of the
8803	medium data in its own storage and therefore can be used independently.
8804	In contrast, a differencing mediun is a "delta" to some other medium and
8805	contains only those sectors which differ from that other medium, which is
8806	then called a <i>parent</i>. The differencing medium is said to be
8807	<i>linked to</i> that parent. The parent may be itself a differencing
8808	medium, thus forming a chain of linked media. The last element in that
8809	chain must always be a base medium. Note that several differencing
8810	media may be linked to the same parent medium.
8811
8812	Differencing media can be distinguished from base media by querying the
8813	<link to="#parent"/> attribute: base media do not have parents they would
8814	depend on, so the value of this attribute is always @c null for them.
8815	Using this attribute, it is possible to walk up the medium tree (from the
8816	child medium to its parent). It is also possible to walk down the tree
8817	using the <link to="#children"/> attribute.
8818
8819	Note that the type of all differencing media is
8820	<link to="MediumType_Normal" />; all other values are meaningless for
8821	them. Base media may be of any type.
8822
8823	<h3>Creating hard disks</h3>
8824
8825	New base hard disks are created using
8826	<link to="IVirtualBox::createHardDisk"/>. Existing hard disks are
8827	opened using <link to="IVirtualBox::openHardDisk"/>. Differencing hard
8828	disks are usually implicitly created by VirtualBox when needed but may
8829	also be created explicitly using <link to="#createDiffStorage"/>.
8830
8831	After the hard disk is successfully created (including the storage unit)
8832	or opened, it becomes a known hard disk (remembered in the internal media
8833	registry). Known hard disks can be attached to a virtual machine, accessed
8834	through <link to="IVirtualBox::getHardDisk"/> and
8835	<link to="IVirtualBox::findHardDisk"/> methods or enumerated using the
8836	<link to="IVirtualBox::hardDisks"/> array (only for base hard disks).
8837
8838	The following methods, besides <link to="IMedium::close"/>,
8839	automatically remove the hard disk from the media registry:
8840	<ul>
8841	<li><link to="#deleteStorage"/></li>
8842	<li><link to="#mergeTo"/></li>
8843	</ul>
8844
8845	If the storage unit of the hard disk is a regular file in the host's
8846	file system then the rules stated in the description of the
8847	<link to="IMedium::location"/> attribute apply when setting its value. In
8848	addition, a plain file name without any path may be given, in which case
8849	the <link to="ISystemProperties::defaultHardDiskFolder"> default hard disk
8850	folder</link> will be prepended to it.
8851
8852	<h4>Automatic composition of the file name part</h4>
8853
8854	Another extension to the <link to="IMedium::location"/> attribute is that
8855	there is a possibility to cause VirtualBox to compose a unique value for
8856	the file name part of the location using the UUID of the hard disk. This
8857	applies only to hard disks in <link to="MediumState_NotCreated"/> state,
8858	e.g. before the storage unit is created, and works as follows. You set the
8859	value of the <link to="IMedium::location"/> attribute to a location
8860	specification which only contains the path specification but not the file
8861	name part and ends with either a forward slash or a backslash character.
8862	In response, VirtualBox will generate a new UUID for the hard disk and
8863	compose the file name using the following pattern:
8864	<pre>
8865	<path>/{<uuid>}.<ext>
8866	</pre>
8867	where <tt><path></tt> is the supplied path specification,
8868	<tt><uuid></tt> is the newly generated UUID and <tt><ext></tt>
8869	is the default extension for the storage format of this hard disk. After
8870	that, you may call any of the methods that create a new hard disk storage
8871	unit and they will use the generated UUID and file name.
8872
8873	<h3>Attaching Hard Disks</h3>
8874
8875	Hard disks are attached to virtual machines using the
8876	<link to="IMachine::attachDevice"/> method and detached using the
8877	<link to="IMachine::detachDevice"/> method. Depending on their
8878	<link to="#type"/>, hard disks are attached either
8879	<i>directly</i> or <i>indirectly</i>.
8880
8881	When a hard disk is being attached directly, it is associated with the
8882	virtual machine and used for hard disk operations when the machine is
8883	running. When a hard disk is being attached indirectly, a new differencing
8884	hard disk linked to it is implicitly created and this differencing hard
8885	disk is associated with the machine and used for hard disk operations.
8886	This also means that if <link to="IMachine::attachDevice"/> performs
8887	a direct attachment then the same hard disk will be returned in response
8888	to the subsequent <link to="IMachine::getMedium"/> call; however if
8889	an indirect attachment is performed then
8890	<link to="IMachine::getMedium"/> will return the implicitly created
8891	differencing hard disk, not the original one passed to <link
8892	to="IMachine::attachDevice"/>. In detail:
8893
8894	<ul>
8895	<li><b>Normal base</b> hard disks that do not have children (i.e.
8896	differencing hard disks linked to them) and that are not already
8897	attached to virtual machines in snapshots are attached <b>directly</b>.
8898	Otherwise, they are attached <b>indirectly</b> because having
8899	dependent children or being part of the snapshot makes it impossible
8900	to modify hard disk contents without breaking the integrity of the
8901	dependent party. The <link to="#readOnly"/> attribute allows to
8902	quickly determine the kind of the attachment for the given hard
8903	disk. Note that if a normal base hard disk is to be indirectly
8904	attached to a virtual machine with snapshots then a special
8905	procedure called <i>smart attachment</i> is performed (see below).</li>
8906	<li><b>Normal differencing</b> hard disks are like normal base hard disks:
8907	they are attached <b>directly</b> if they do not have children and are
8908	not attached to virtual machines in snapshots, and <b>indirectly</b>
8909	otherwise. Note that the smart attachment procedure is never performed
8910	for differencing hard disks.</li>
8911	<li><b>Immutable</b> hard disks are always attached <b>indirectly</b> because
8912	they are designed to be non-writable. If an immutable hard disk is
8913	attached to a virtual machine with snapshots then a special
8914	procedure called smart attachment is performed (see below).</li>
8915	<li><b>Writethrough</b> hard disks are always attached <b>directly</b>,
8916	also as designed. This also means that writethrough hard disks cannot
8917	have other hard disks linked to them at all.</li>
8918	</ul>
8919
8920	Note that the same hard disk, regardless of its type, may be attached to
8921	more than one virtual machine at a time. In this case, the machine that is
8922	started first gains exclusive access to the hard disk and attempts to
8923	start other machines having this hard disk attached will fail until the
8924	first machine is powered down.
8925
8926	Detaching hard disks is performed in a <i>deferred</i> fashion. This means
8927	that the given hard disk remains associated with the given machine after a
8928	successful <link to="IMachine::detachDevice"/> call until
8929	<link to="IMachine::saveSettings"/> is called to save all changes to
8930	machine settings to disk. This deferring is necessary to guarantee that
8931	the hard disk configuration may be restored at any time by a call to
8932	<link to="IMachine::discardSettings"/> before the settings
8933	are saved (committed).
8934
8935	Note that if <link to="IMachine::discardSettings"/> is called after
8936	indirectly attaching some hard disks to the machine but before a call to
8937	<link to="IMachine::saveSettings"/> is made, it will implicitly delete
8938	all differencing hard disks implicitly created by
8939	<link to="IMachine::attachDevice"/> for these indirect attachments.
8940	Such implicitly created hard disks will also be immediately deleted when
8941	detached explicitly using the <link to="IMachine::detachDevice"/>
8942	call if it is made before <link to="IMachine::saveSettings"/>. This
8943	implicit deletion is safe because newly created differencing hard
8944	disks do not contain any user data.
8945
8946	However, keep in mind that detaching differencing hard disks that were
8947	implicitly created by <link to="IMachine::attachDevice"/>
8948	before the last <link to="IMachine::saveSettings"/> call will
8949	<b>not</b> implicitly delete them as they may already contain some data
8950	(for example, as a result of virtual machine execution). If these hard
8951	disks are no more necessary, the caller can always delete them explicitly
8952	using <link to="#deleteStorage"/> after they are actually de-associated
8953	from this machine by the <link to="IMachine::saveSettings"/> call.
8954
8955	<h3>Smart Attachment</h3>
8956
8957	When normal base or immutable hard disks are indirectly attached to a
8958	virtual machine then some additional steps are performed to make sure the
8959	virtual machine will have the most recent "view" of the hard disk being
8960	attached. These steps include walking through the machine's snapshots
8961	starting from the current one and going through ancestors up to the first
8962	snapshot. Hard disks attached to the virtual machine in all
8963	of the encountered snapshots are checked whether they are descendants of
8964	the given normal base or immutable hard disk. The first found child (which
8965	is the differencing hard disk) will be used instead of the normal base or
8966	immutable hard disk as a parent for creating a new differencing hard disk
8967	that will be actually attached to the machine. And only if no descendants
8968	are found or if the virtual machine does not have any snapshots then the
8969	normal base or immutable hard disk will be used itself as a parent for
8970	this differencing hard disk.
8971
8972	It is easier to explain what smart attachment does using the
8973	following example:
8974	<pre>
8975	BEFORE attaching B.vdi: AFTER attaching B.vdi:
8976
8977	Snapshot 1 (B.vdi) Snapshot 1 (B.vdi)
8978	Snapshot 2 (D1->B.vdi) Snapshot 2 (D1->B.vdi)
8979	Snapshot 3 (D2->D1.vdi) Snapshot 3 (D2->D1.vdi)
8980	Snapshot 4 (none) Snapshot 4 (none)
8981	CurState (none) CurState (D3->D2.vdi)
8982
8983	NOT
8984	...
8985	CurState (D3->B.vdi)
8986	</pre>
8987	The first column is the virtual machine configuration before the base hard
8988	disk <tt>B.vdi</tt> is attached, the second column shows the machine after
8989	this hard disk is attached. Constructs like <tt>D1->B.vdi</tt> and similar
8990	mean that the hard disk that is actually attached to the machine is a
8991	differencing hard disk, <tt>D1.vdi</tt>, which is linked to (based on)
8992	another hard disk, <tt>B.vdi</tt>.
8993
8994	As we can see from the example, the hard disk <tt>B.vdi</tt> was detached
8995	from the machine before taking Snapshot 4. Later, after Snapshot 4 was
8996	taken, the user decides to attach <tt>B.vdi</tt> again. <tt>B.vdi</tt> has
8997	dependent child hard disks (<tt>D1.vdi</tt>, <tt>D2.vdi</tt>), therefore
8998	it cannot be attached directly and needs an indirect attachment (i.e.
8999	implicit creation of a new differencing hard disk). Due to the smart
9000	attachment procedure, the new differencing hard disk
9001	(<tt>D3.vdi</tt>) will be based on <tt>D2.vdi</tt>, not on
9002	<tt>B.vdi</tt> itself, since <tt>D2.vdi</tt> is the most recent view of
9003	<tt>B.vdi</tt> existing for this snapshot branch of the given virtual
9004	machine.
9005
9006	Note that if there is more than one descendant hard disk of the given base
9007	hard disk found in a snapshot, and there is an exact device, channel and
9008	bus match, then this exact match will be used. Otherwise, the youngest
9009	descendant will be picked up.
9010
9011	There is one more important aspect of the smart attachment procedure which
9012	is not related to snapshots at all. Before walking through the snapshots
9013	as described above, the backup copy of the current list of hard disk
9014	attachment is searched for descendants. This backup copy is created when
9015	the hard disk configuration is changed for the first time after the last
9016	<link to="IMachine::saveSettings"/> call and used by
9017	<link to="IMachine::discardSettings"/> to undo the recent hard disk
9018	changes. When such a descendant is found in this backup copy, it will be
9019	simply re-attached back, without creating a new differencing hard disk for
9020	it. This optimization is necessary to make it possible to re-attach the
9021	base or immutable hard disk to a different bus, channel or device slot
9022	without losing the contents of the differencing hard disk actually
9023	attached to the machine in place of it.

9086
9087	When setting a value of the location attribute which is a regular file
9088	in the host's file system, the given file name may be either relative to
9089	the <link to="IVirtualBox::homeFolder">VirtualBox home folder</link> or

9376	<method name="lockRead">
9377	<desc>
9378	Locks this medium for reading.
9379
9380	A read lock is shared: many clients can simultaneously lock the
9381	same medium for reading unless it is already locked for writing (see
9382	<link to="#lockWrite"/>) in which case an error is returned.
9383
9384	When the medium is locked for reading, it cannot be modified
9385	from within VirtualBox. This means that any method that changes
9386	the properties of this medium or contents of the storage unit
9387	will return an error (unless explicitly stated otherwise). That
9388	includes an attempt to start a virtual machine that wants to
9389	write to the the medium.
9390
9391	When the virtual machine is started up, it locks for reading all
9392	media it uses in read-only mode. If some medium cannot be locked
9393	for reading, the startup procedure will fail.
9394	A medium is typically locked for reading while it is used by a running
9395	virtual machine but has a depending differencing image that receives
9396	the actual write operations. This way one base medium can have
9397	multiple child differencing images which can be written to
9398	simultaneously. Read-only media such as DVD and floppy images are
9399	also locked for reading only (so they can be in use by multiple
9400	machines simultaneously).
9401
9402	A medium is also locked for reading when it is the source of a
9403	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9404
9405	The medium locked for reading must be unlocked using the <link
9406	to="#unlockRead"/> method. Calls to <link to="#lockRead"/>
9407	can be nested and must be followed by the same number of paired
9408	<link to="#unlockRead"/> calls.
9409
9410	This method sets the medium state (see <link to="#state"/>) to
9411	"LockedRead" on success. The medium's previous state must be
9412	one of "Created", "Inaccessible" or "LockedRead".
9413
9414	Locking an inaccessible medium is not an error; this method performs
9415	a logical lock that prevents modifications of this medium through
9416	the VirtualBox API, not a physical file-system lock of the underlying
9417	storage unit.
9418
9419	This method returns the current state of the medium

9456	<method name="lockWrite">
9457	<desc>
9458	Locks this medium for writing.
9459
9460	A write lock, as opposed to <link to="#lockRead"/>, is
9461	exclusive: there may be only one client holding a write lock,
9462	and there may be no read locks while the write lock is held.
9463	As a result, read-locking fails if a write lock is held, and
9464	write-locking fails if either a read or another write lock is held.
9465
9466	When a medium is locked for writing, it cannot be modified
9467	from within VirtualBox, and it is not guaranteed that the values
9468	of its properties are up-to-date. Any method that changes the
9469	properties of this medium or contents of the storage unit will
9470	return an error (unless explicitly stated otherwise).
9471
9472	When a virtual machine is started up, it locks for writing all
9473	media it uses to write data to. If any medium could not be locked
9474	for writing, the startup procedure will fail. If a medium has
9475	differencing images, then while the machine is running, only
9476	the last ("leaf") differencing image is locked for writing,
9477	whereas its parents are locked for reading only.
9478
9479	A medium is also locked for writing when it is the target of a
9480	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9481
9482	The medium locked for writing must be unlocked using the <link
9483	to="#unlockWrite"/> method. Write locks <i>cannot</i> be nested.
9484
9485	This method sets the medium state (see <link to="#state"/>) to

9809
9810	The target medium must be either a descendant of this medium or
9811	its ancestor (otherwise this method will immediately return a failure).
9812	It follows that there are two logical directions of the merge operation:
9813	from ancestor to descendant (<i>forward merge</i>) and from descendant to
9814	ancestor (<i>backward merge</i>). Let us consider the following medium
9815	chain:
9816
9817	<pre>Base <- Diff_1 <- Diff_2</pre>
9818
9819	Here, calling this method on the <tt>Base</tt> medium object with
9820	<tt>Diff_2</tt> as an argument will be a forward merge; calling it on
9821	<tt>Diff_2</tt> with <tt>Base</tt> as an argument will be a backward
9822	merge. Note that in both cases the contents of the resulting medium
9823	will be the same, the only difference is the medium object that takes
9824	the result of the merge operation. In case of the forward merge in the
9825	above example, the result will be written to <tt>Diff_2</tt>; in case of
9826	the backward merge, the result will be written to <tt>Base</tt>. In
9827	other words, the result of the operation is always stored in the target
9828	medium.
9829
9830	Upon successful operation completion, the storage units of all media in
9831	the chain between this (source) medium and the target medium, including
9832	the source medium itself, will be automatically deleted and the
9833	relevant medium objects (including this medium) will become
9834	uninitialized. This means that any attempt to call any of
9835	their methods or attributes will fail with the
9836	<tt>"Object not ready" (E_ACCESSDENIED)</tt> error. Applied to the above
9837	example, the forward merge of <tt>Base</tt> to <tt>Diff_2</tt> will

9839	Note that <tt>Diff_2</tt> in this case will become a base medium
9840	itself since it will no longer be based on any other medium.
9841
9842	Considering the above, all of the following conditions must be met in
9843	order for the merge operation to succeed:
9844	<ul>
9845	<li>
9846	Neither this (source) medium nor any intermediate
9847	differencing medium in the chain between it and the target
9848	medium is attached to any virtual machine.
9849	</li>
9850	<li>
9851	Neither the source medium nor the target medium is an
9852	<link to="MediumType_Immutable"/> medium.
9853	</li>
9854	<li>
9855	The part of the medium tree from the source medium to the
9856	target medium is a linear chain, i.e. all medium in this
9857	chain have exactly one child which is the next medium in this
9858	chain. The only exception from this rule is the target medium in
9859	the forward merge operation; it is allowed to have any number of
9860	child media because the merge operation will not change its
9861	logical contents (as it is seen by the guest OS or by children).
9862	</li>
9863	<li>
9864	None of the involved media are in
9865	<link to="MediumState_LockedRead"/> or
9866	<link to="MediumState_LockedWrite"/> state.
9867	</li>
9868	</ul>
9869
9870	<note>
9871	This (source) medium and all intermediates will be placed to <link
9872	to="MediumState_Deleting"/> state and the target medium will be

9874	duration of this operation.

9896	successful completion, the cloned medium will contain exactly the

9898	first case a new UUID for the clone will be randomly generated, and in
9899	the second case the UUID will remain unchanged.
9900
9901	The @a parent argument defines which medium will be the parent
9902	of the clone. Passing a @c null reference indicates that the clone will
9903	be a base image, i.e. completely independent. It is possible to specify
9904	an arbitrary medium for this parameter, including the parent of the
9905	medium which is being cloned. Even cloning to a child of the source
9906	medium is possible. Note that when cloning to an existing image, the
9907	@a parent irgument is ignored.
9908

10596
10597	There are two modes of working with the video buffer of the virtual
10598	machine. The <i>indirect</i> mode implies that the IFramebuffer
10599	implementation allocates a memory buffer for the requested display mode
10600	and provides it to the virtual machine. In <i>direct</i> mode, the
10601	IFramebuffer implementation uses the memory buffer allocated and owned
10602	by the virtual machine. This buffer represents the video memory of the
10603	emulated video adapter (so called <i>guest VRAM</i>). The direct mode is
10604	usually faster because the implementation gets a raw pointer to the
10605	guest VRAM buffer which it can directly use for visualizing the contents
10606	of the virtual display, as opposed to the indirect mode where the
10607	contents of guest VRAM are copied to the memory buffer provided by
10608	the implementation every time a display update occurs.
10609
10610	It is important to note that the direct mode is really fast only when
10611	the implementation uses the given guest VRAM buffer directly, for
10612	example, by blitting it to the window representing the virtual machine's
10613	display, which saves at least one copy operation comparing to the
10614	indirect mode. However, using the guest VRAM buffer directly is not
10615	always possible: the format and the color depth of this buffer may be
10616	not supported by the target window, or it may be unknown (opaque) as in
10617	case of text or non-linear multi-plane VGA video modes. In this case,
10618	the indirect mode (that is always available) should be used as a
10619	fallback: when the guest VRAM contents are copied to the
10620	implementation-provided memory buffer, color and format conversion is
10621	done automatically by the underlying code.
10622
10623	The @a pixelFormat parameter defines whether the direct mode is
10624	available or not. If @a pixelFormat is <link
10625	to="FramebufferPixelFormat_Opaque"/> then direct access to the guest
10626	VRAM buffer is not available -- the @a VRAM, @a bitsPerPixel and
10627	@a bytesPerLine parameters must be ignored and the implementation must use
10628	the indirect mode (where it provides its own buffer in one of the
10629	supported formats). In all other cases, @a pixelFormat together with
10630	@a bitsPerPixel and @a bytesPerLine define the format of the video memory
10631	buffer pointed to by the @a VRAM parameter and the implementation is
10632	free to choose which mode to use. To indicate that this frame buffer uses
10633	the direct mode, the implementation of the <link to="#usesGuestVRAM"/>
10634	attribute must return @c true and <link to="#address"/> must
10635	return exactly the same address that is passed in the @a VRAM parameter
10636	of this method; otherwise it is assumed that the indirect strategy is
10637	chosen.
10638
10639	The @a width and @a height parameters represent the size of the
10640	requested display mode in both modes. In case of indirect mode, the
10641	provided memory buffer should be big enough to store data of the given
10642	display mode. In case of direct mode, it is guaranteed that the given
10643	@a VRAM buffer contains enough space to represent the display mode of the
10644	given size. Note that this frame buffer's <link to="#width"/> and <link
10645	to="#height"/> attributes must return exactly the same values as
10646	passed to this method after the resize is completed (see below).
10647
10648	The @a finished output parameter determines if the implementation has
10649	finished resizing the frame buffer or not. If, for some reason, the
10650	resize cannot be finished immediately during this call, @a finished
10651	must be set to @c false, and the implementation must call
10652	<link to="IDisplay::resizeCompleted"/> after it has returned from
10653	this method as soon as possible. If @a finished is @c false, the
10654	machine will not call any frame buffer methods until
10655	<link to="IDisplay::resizeCompleted"/> is called.
10656
10657	Note that if the direct mode is chosen, the <link to="#bitsPerPixel"/>,
10658	<link to="#bytesPerLine"/> and <link to="#pixelFormat"/> attributes of
10659	this frame buffer must return exactly the same values as specified in the
10660	parameters of this method, after the resize is completed. If the
10661	indirect mode is chosen, these attributes must return values describing
10662	the format of the implementation's own memory buffer <link
10663	to="#address"/> points to. Note also that the <link to="#bitsPerPixel"/>
10664	value must always correlate with <link to="#pixelFormat"/>. Note that
10665	the <link to="#pixelFormat"/> attribute must never return <link
10666	to="FramebufferPixelFormat_Opaque"/> regardless of the selected mode.

11290	In host pipe mode, the #path attribute specifies the path to the pipe on

11790	<desc>
11791	The IUSBDeviceFilter interface represents an USB device filter used
11792	to perform actions on a group of USB devices.
11793
11794	This type of filters is used by running virtual machines to
11795	automatically capture selected USB devices once they are physically
11796	attached to the host computer.
11797
11798	A USB device is matched to the given device filter if and only if all
11799	attributes of the device match the corresponding attributes of the
11800	filter (that is, attributes are joined together using the logical AND
11801	operation). On the other hand, all together, filters in the list of
11802	filters carry the semantics of the logical OR operation. So if it is
11803	desirable to create a match like "this vendor id OR this product id",
11804	one needs to create two filters and specify "any match" (see below)
11805	for unused attributes.
11806
11807	All filter attributes used for matching are strings. Each string
11808	is an expression representing a set of values of the corresponding
11809	device attribute, that will match the given filter. Currently, the
11810	following filtering expressions are supported:
11811
11812	<ul>
11813	<li><i>Interval filters</i>. Used to specify valid intervals for
11814	integer device attributes (Vendor ID, Product ID and Revision).
11815	The format of the string is:
11816
11817	<tt>int:((m)\|([m]-[n]))(,(m)\|([m]-[n]))*</tt>
11818
11819	where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
11820	(starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
11821	or decimal (otherwise) form, so that <tt>m < n</tt>. If <tt>m</tt>
11822	is omitted before a dash (<tt>-</tt>), the minimum possible integer
11823	is assumed; if <tt>n</tt> is omitted after a dash, the maximum
11824	possible integer is assumed.
11825	</li>
11826	<li><i>Boolean filters</i>. Used to specify acceptable values for
11827	boolean device attributes. The format of the string is:
11828
11829	<tt>true\|false\|yes\|no\|0\|1</tt>
11830
11831	</li>
11832	<li><i>Exact match</i>. Used to specify a single value for the given
11833	device attribute. Any string that doesn't start with <tt>int:</tt>
11834	represents the exact match. String device attributes are compared to
11835	this string including case of symbols. Integer attributes are first
11836	converted to a string (see individual filter attributes) and then
11837	compared ignoring case.

11960	USB device state. This enumeration represents all possible states
11961	of the USB device physically attached to the host computer regarding
11962	its state on the host computer and availability to guest computers
11963	(all currently running virtual machines).
11964
11965	Once a supported USB device is attached to the host, global USB
11966	filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
11967	either ignore the device, or put it to USBDeviceState_Held state, or do
11968	nothing. Unless the device is ignored by global filters, filters of all
11969	currently running guests (<link to="IUSBController::deviceFilters"/>) are
11970	activated that can put it to USBDeviceState_Captured state.
11971
11972	If the device was ignored by global filters, or didn't match
11973	any filters at all (including guest ones), it is handled by the host
11974	in a normal way. In this case, the device state is determined by
11975	the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
11976	or USBDeviceState_Available, depending on the current device usage.
11977
11978	Besides auto-capturing based on filters, the device can be manually
11979	captured by guests (<link to="IConsole::attachUSBDevice"/>) if its
11980	state is USBDeviceState_Busy, USBDeviceState_Available or
11981	USBDeviceState_Held.
11982
11983	<note>
11984	Due to differences in USB stack implementations in Linux and Win32,
11985	states USBDeviceState_Busy and USBDeviceState_vailable are applicable
11986	only to the Linux version of the product. This also means that (<link

12277	<desc>
12278	The ISharedFolder interface represents a folder in the host computer's
12279	file system accessible from the guest OS running inside a virtual
12280	machine using an associated logical name.
12281
12282	There are three types of shared folders:
12283	<ul>
12284	<li><i>Global</i> (<link to="IVirtualBox::sharedFolders"/>), shared
12285	folders available to all virtual machines.</li>
12286	<li><i>Permanent</i> (<link to="IMachine::sharedFolders"/>),
12287	VM-specific shared folders available to the given virtual machine at
12288	startup.</li>
12289	<li><i>Transient</i> (<link to="IConsole::sharedFolders"/>),
12290	VM-specific shared folders created in the session context (for
12291	example, when the virtual machine is running) and automatically
12292	discarded when the session is closed (the VM is powered off).</li>
12293	</ul>
12294
12295	Logical names of shared folders must be unique within the given scope
12296	(global, permanent or transient). However, they do not need to be unique
12297	across scopes. In this case, the definition of the shared folder in a
12298	more specific scope takes precedence over definitions in all other
12299	scopes. The order of precedence is (more specific to more general):
12300	<ol>
12301	<li>Transient definitions</li>
12302	<li>Permanent definitions</li>
12303	<li>Global definitions</li>
12304	</ol>
12305
12306	For example, if MyMachine has a shared folder named
12307	<tt>C_DRIVE</tt> (that points to <tt>C:\\</tt>), then creating a
12308	transient shared folder named <tt>C_DRIVE</tt> (that points
12309	to <tt>C:\\\\WINDOWS</tt>) will change the definition
12310	of <tt>C_DRIVE</tt> in the guest OS so
12311	that <tt>\\\\VBOXSVR\\C_DRIVE</tt> will give access
12312	to <tt>C:\\WINDOWS</tt> instead of <tt>C:\\</tt> on the host
12313	PC. Removing the transient shared folder <tt>C_DRIVE</tt> will restore
12314	the previous (permanent) definition of <tt>C_DRIVE</tt> that points
12315	to <tt>C:\\</tt> if it still exists.
12316
12317	Note that permanent and transient shared folders of different machines
12318	are in different name spaces, so they don't overlap and don't need to
12319	have unique logical names.
12320

12727	<desc>
12728	The ISession interface represents a serialization primitive for virtual
12729	machines.
12730
12731	With VirtualBox, every time one wishes to manipulate a virtual machine
12732	(e.g. change its settings or start execution), a session object is
12733	required. Such an object must be passed to one of the session methods
12734	that open the given session, which then initiates the machine manipulation.
12735
12736	A session serves several purposes: it identifies to the inter-process VirtualBox
12737	code which process is currently working with the virtual machine, and it ensures
12738	that there are no incompatible requests from several processes for the
12739	same virtual machine. Session objects can therefore be thought of as mutex
12740	semaphores that lock virtual machines to prevent conflicting accesses from
12741	several processes.
12742
12743	How sessions objects are used depends on whether you use the Main API
12744	via COM or via the webservice:
12745
12746	<ul>
12747	<li>When using the COM API directly, an object of the Session class from the
12748	VirtualBox type library needs to be created. In regular COM C++ client code,
12749	this can be done by calling <tt>createLocalObject()</tt>, a standard COM API.
12750	This object will then act as a local session object in further calls to open
12751	a session.
12752	</li>
12753
12754	<li>In the webservice, the session manager (IWebsessionManager) instead creates
12755	one session object automatically when <link to="IWebsessionManager::logon" />
12756	is called. A managed object reference to that session object can be retrieved by
12757	calling <link to="IWebsessionManager::getSessionObject" />. This session object
12758	reference can then be used to open sessions.
12759	</li>
12760	</ul>
12761
12762	Sessions are mainly used in two variations:
12763
12764	<ul>
12765	<li>
12766	To start a virtual machine in a separate process, one would call
12767	<link to="IVirtualBox::openRemoteSession"/>, which requires a session
12768	object as its first parameter. This session then identifies the caller
12769	and lets him control the started machine (for example, pause machine
12770	execution or power it down) as well as be notified about machine
12771	execution state changes.
12772	</li>
12773
12774	<li>To alter machine settings, or to start machine execution within the
12775	current process, one needs to open a direct session for the machine first by
12776	calling <link to="IVirtualBox::openSession"/>. While a direct session
12777	is open within one process, no any other process may open another direct
12778	session for the same machine. This prevents the machine from being changed
12779	by other processes while it is running or while the machine is being configured.
12780	</li>
12781	</ul>
12782
12783	One also can attach to an existing direct session already opened by
12784	another process (for example, in order to send a control request to the
12785	virtual machine such as the pause or the reset request). This is done by
12786	calling <link to="IVirtualBox::openExistingSession"/>.
12787
12788	<note>
12789	Unless you are trying to write a new VirtualBox front-end that
12790	performs direct machine execution (like the VirtualBox or VBoxSDL
12791	front-ends), don't call <link to="IConsole::powerUp"/> in a direct
12792	session opened by <link to="IVirtualBox::openSession"/> and use this
12793	session only to change virtual machine settings. If you simply want to
12794	start virtual machine execution using one of the existing front-ends
12795	(for example the VirtualBox GUI or headless server), simply use
12796	<link to="IVirtualBox::openRemoteSession"/>; these front-ends
12797	will power up the machine automatically for you.

12824
12825	It is recommended that every time an "open session" method (such as
12826	<link to="IVirtualBox::openRemoteSession" /> or
12827	<link to="IVirtualBox::openSession" />) has been called to
12828	manipulate a virtual machine, the caller invoke
12829	ISession::close() when it's done doing so. Since sessions are
12830	serialization primitives much like ordinary mutexes, they are
12831	best used the same way: for each "open" call, there should be
12832	a matching "close" call, even when errors occur.
12833
12834	Otherwise, if a direct session for a machine opened with
12835	<link to="IVirtualBox::openSession"/> is not explicitly closed
12836	when the application terminates, the state of the machine will
12837	be set to <link to="MachineState_Aborted" /> on the server.
12838
12839	Generally, it is recommended to close all open sessions explicitly
12840	before terminating the application (regardless of the reason for
12841	the termination).
12842

13217	The IPerformanceCollector interface represents a service that collects and
13218	stores performance metrics data.
13219
13220	Performance metrics are associated with objects of interfaces like IHost and
13221	IMachine. Each object has a distinct set of performance metrics.
13222	The set can be obtained with <link to="IPerformanceCollector::getMetrics"/>.
13223
13224	Metric data is collected at the specified intervals and is retained
13225	internally. The interval and the number of retained samples can be set
13226	with <link to="IPerformanceCollector::setupMetrics" />.
13227
13228	Metrics are organized hierarchically, with each level separated by a
13229	slash (/) character. Generally, the scheme for metric names is like this:
13230
13231	<tt>Category/Metric[/SubMetric][:aggregation]</tt>
13232
13233	"Category/Metric" together form the base metric name. A base metric is the
13234	smallest unit for which a sampling interval and the number of retained
13235	samples can be set. Only base metrics can be enabled and disabled. All
13236	sub-metrics are collected when their base metric is collected.
13237	Collected values for any set of sub-metrics can be queried with
13238	<link to="IPerformanceCollector::queryMetricsData" />.
13239
13240	For example "CPU/Load/User:avg"
13241	metric name stands for the "CPU" category, "Load" metric, "User" submetric,
13242	"average" aggregate. An aggregate function is computed over all retained
13243	data. Valid aggregate functions are:
13244
13245	<ul>
13246	<li>avg -- average</li>
13247	<li>min -- minimum</li>
13248	<li>max -- maximum</li>
13249	</ul>
13250
13251	When setting up
13252	metric parameters, querying metric data, enabling or disabling metrics
13253	wildcards can be used in metric names to specify a subset of metrics. For
13254	example, to select all CPU-related metrics use <tt>CPU/*</tt>, all
13255	averages can be queried using <tt>*:avg</tt> and so on. To query metric
13256	values without aggregates <tt>*:</tt> can be used.
13257
13258	The valid names for base metrics are:
13259
13260	<ul>
13261	<li>CPU/Load</li>
13262	<li>CPU/MHz</li>
13263	<li>RAM/Usage</li>
13264	</ul>
13265
13266	The general sequence for collecting and retrieving the metrics is:
13267	<ul>
13268	<li>
13269	Obtain an instance of IPerformanceCollector with
13270	<link to="IVirtualBox::performanceCollector" />
13271	</li>
13272	<li>
13273	Allocate and populate an array with references to objects the metrics
13274	will be collected for. Use references to IHost and IMachine objects.
13275	</li>
13276	<li>
13277	Allocate and populate an array with base metric names the data will be
13278	collected for.
13279	</li>
13280	<li>
13281	Call <link to="IPerformanceCollector::setupMetrics" />. From now on the
13282	metric data will be collected and stored.
13283	</li>
13284	<li>
13285	Wait for the data to get collected.
13286	</li>
13287	<li>
13288	Allocate and populate an array with references to objects the metric
13289	values will be queried for. You can re-use the object array used for
13290	setting base metrics.
13291	</li>
13292	<li>
13293	Allocate and populate an array with metric names the data will be
13294	collected for. Note that metric names differ from base metric names.
13295	</li>
13296	<li>
13297	Call <link to="IPerformanceCollector::queryMetricsData" />. The data that
13298	have been collected so far are returned. Note that the values are still
13299	retained internally and data collection continues.

13480	<note>
13481	Data collection continues behind the scenes after call to
13482	@c queryMetricsData. The return data can be seen as the snapshot of
13483	the current state at the time of @c queryMetricsData call. The
13484	internally kept metric values are not cleared by the call. This makes
13485	possible querying different subsets of metrics or aggregates with
13486	subsequent calls. If periodic querying is needed it is highly
13487	suggested to query the values with @c interval*count period to avoid
13488	confusion. This way a completely new set of data values will be
13489	provided by each query.
