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.

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.

501	\| +-------- Saving <--------[saveState()]<----------+---------------------+
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.

1128	name="IVirtualBoxErrorInfo" extends="$errorinfo"
1129	uuid="4b86d186-407e-4f9e-8be8-e50061be8725"

1131	wsmap="managed"
1132	>
1133	<desc>
1134	The IVirtualBoxErrorInfo interface represents extended error information.
1135
1136	Extended error information can be set by VirtualBox components after
1137	unsuccessful or partially successful method invocation. This information
1138	can be retrieved by the calling party as an IVirtualBoxErrorInfo object
1139	and then shown to the client in addition to the plain 32-bit result code.
1140
1141	In MS COM, this interface extends the IErrorInfo interface,
1142	in XPCOM, it extends the nsIException interface. In both cases,
1143	it provides a set of common attributes to retrieve error
1144	information.
1145
1146	Sometimes invocation of some component's method may involve methods of
1147	other components that may also fail (independently of this method's
1148	failure), or a series of non-fatal errors may precede a fatal error that
1149	causes method failure. In cases like that, it may be desirable to preserve
1150	information about all errors happened during method invocation and deliver
1151	it to the caller. The <link to="#next"/> attribute is intended
1152	specifically for this purpose and allows to represent a chain of errors
1153	through a single IVirtualBoxErrorInfo object set after method invocation.
1154
1155	Note that errors are stored to a chain in the reverse order, i.e. the
1156	initial error object you query right after method invocation is the last
1157	error set by the callee, the object it points to in the @a next attribute
1158	is the previous error and so on, up to the first error (which is the last
1159	in the chain).

1164	Result code of the error.
1165	Usually, it will be the same as the result code returned
1166	by the method that provided this error information, but not
1167	always. For example, on Win32, CoCreateInstance() will most
1168	likely return E_NOINTERFACE upon unsuccessful component
1169	instantiation attempt, but not the value the component factory
1170	returned. Value is typed 'long', not 'result',
1171	to make interface usable from scripting languages.

1601	The IVirtualBox interface represents the main interface exposed by the
1602	product that provides virtual machine management.
1603
1604	An instance of IVirtualBox is required for the product to do anything
1605	useful. Even though the interface does not expose this, internally,
1606	IVirtualBox is implemented as a singleton and actually lives in the
1607	process of the VirtualBox server (VBoxSVC.exe). This makes sure that
1608	IVirtualBox can track the state of all virtual machines on a particular
1609	host, regardless of which frontend started them.

1731	<method name="createMachine">
1732	<desc>
1733	Creates a new virtual machine.
1734
1735	The new machine is created unregistered, with the initial configuration
1736	set according to the specified guest OS type. A typical sequence of
1737	actions to create a new virtual machine is as follows:
1738
1739	<ol>
1740	<li>
1741	Call this method to have a new machine created. The returned machine
1742	object will be "mutable" allowing to change any machine property.
1743	</li>
1744
1745	<li>
1746	Configure the machine using the appropriate attributes and methods.
1747	</li>
1748
1749	<li>
1750	Call <link to="IMachine::saveSettings" /> to write the settings
1751	to the machine's XML settings file. The configuration of the newly
1752	created machine will not be saved to disk until this method is
1753	called.
1754	</li>
1755
1756	<li>
1757	Call <link to="#registerMachine" /> to add the machine to the list
1758	of machines known to VirtualBox.
1759	</li>
1760	</ol>
1761
1762	You should specify valid name for the newly created machine when calling
1763	this method. See the <link to="IMachine::name"/> attribute description
1764	for more details about the machine name.
1765
1766	The specified guest OS type identifier must match an ID of one of known
1767	guest OS types listed in the <link to="IVirtualBox::guestOSTypes"/>
1768	array.
1769
1770	Every machine has a <i>settings file</i> that is used to store
1771	the machine configuration. This file is stored in a directory called the
1772	<i>machine settings subfolder</i>. Both the settings subfolder and file
1773	will have a name that corresponds to the name of the virtual machine.
1774	You can specify where to create the machine setting subfolder using the
1775	@a baseFolder argument. The base folder can be absolute (full path) or
1776	relative to the <link to="IVirtualBox::homeFolder">VirtualBox home
1777	directory</link>.
1778
1779	If @a baseFolder is a @c null or empty string (which is recommended), the
1780	<link to="ISystemProperties::defaultMachineFolder">default machine
1781	settings folder</link> will be used as a base folder for the created
1782	machine. Otherwise the given base folder will be used. In either case,
1783	the full path to the resulting settings file has the following
1784	structure:
1785	<pre>
1786	<base_folder>/<machine_name>/<machine_name>.xml
1787	</pre>
1788
1789	Note that if the resulting settings file already exists, this method
1790	will fail with <link to="VBOX_E_FILE_ERROR"/>.
1791
1792	Optionally, you may specify an UUID of to assign to the created machine.
1793	However, this is not recommended and you should normally pass an empty
1794	(@c null) UUID to this method so that a new UUID will be automatically
1795	generated for every created machine. You can use UUID
1796	00000000-0000-0000-0000-000000000000 as @c null value.
1797
1798	<note>
1799	There is no way to change the name of the settings file or
1800	subfolder of the created machine directly.

2097	Opens a medium from an existing location, optionally replacing
2098	the image UUID and/or parent UUID.
2099
2100	After the medium is successfully opened by this method, it gets
2101	remembered by (known to) this VirtualBox installation and will be
2102	accessible through <link to="#getHardDisk"/> and
2103	<link to="#findHardDisk"/> methods. Remembered base media
2104	are also returned as part of the <link to="#hardDisks"/> array and can
2105	be attached to virtual machines. See IMedium for more details.
2106
2107	If a differencing medium is to be opened by this method, the
2108	operation will succeed only if its parent medium and all ancestors,
2109	if any, are already known to this VirtualBox installation (for example,
2110	were opened by this method before).
2111
2112	This method tries to guess the storage format of the specified medium
2113	by reading medium data at the specified location.
2114
2115	If @a write is ReadWrite (which it should be), the image is opened for
2116	read/write access and must have according permissions, as VirtualBox
2117	may actually write status information into the disk's metadata sections.
2118
2119	Note that write access is required for all typical image usage in VirtualBox,
2120	since VirtualBox may need to write metadata such as a UUID into the image.
2121	The only exception is opening a source image temporarily for copying and
2122	cloning when the image will quickly be closed again.
2123
2124	Note that the format of the location string is storage format specific.

2575	<desc>
2576	Opens a new direct session with the given virtual machine.

2578	A direct session acts as a local lock on the given VM.
2579	There can be only one direct session open at a time for every

2583	and execute the VM in the process space of the session object.
2584
2585	Sessions therefore can be compared to mutex semaphores that
2586	lock a given VM for modification and execution.
2587	See <link to="ISession">ISession</link> for details.
2588
2589	<note>Unless you are writing a new VM frontend, you will not

2600	object, on which you may invoke IMachine methods to change its
2601	settings, will be a different object from the immutable IMachine
2602	objects returned by various IVirtualBox methods. To obtain a
2603	mutable IMachine object (upon which you can invoke settings methods),
2604	use the <link to="ISession::machine" /> attribute.
2605
2606	One must always call <link to="ISession::close" /> to release the
2607	lock on the machine, or the machine's state will eventually be
2608	set to "Aborted".
2609
2610	In other words, to change settings on a machine, the following
2611	sequence is typically performed:
2612
2613	<ol>
2614	<li>Call this method (openSession) to have a machine locked for
2615	the current session.</li>
2616
2617	<li>Obtain a mutable IMachine object from <link to="ISession::machine" />.</li>
2618
2619	<li>Change the settings of the machine.</li>
2620
2621	<li>Call <link to="IMachine::saveSettings" />.</li>
2622
2623	<li>Close the session by calling <link to="ISession::close"/>.</li>

2659	<method name="openRemoteSession">
2660	<desc>
2661	Spawns a new process that executes a virtual machine (called a
2662	"remote session").
2663
2664	Opening a remote session causes the VirtualBox server to start a new
2665	process that opens a direct session with the given VM. As a result, the
2666	VM is locked by that direct session in the new process, preventing
2667	conflicting changes from other processes. Since sessions act as locks
2668	that prevent conflicting changes, one cannot open a remote session
2669	for a VM that already has another open session (direct or remote), or
2670	is currently in the process of opening one (see <link
2671	to="IMachine::sessionState"/>).
2672
2673	While the remote session still provides some level of control over the
2674	VM execution to the caller (using the <link to="IConsole" /> interface),
2675	not all VM settings are available for modification within the remote
2676	session context.
2677
2678	This operation can take some time (a new VM is started in a new process,
2679	for which memory and other resources need to be set up). Because of this,
2680	an <link to="IProgress" /> is returned to allow the caller to wait for this
2681	asynchronous operation to be completed. Until then, the remote session
2682	object remains in the closed state, and accessing the machine or its
2683	console through it is invalid. It is recommended to use
2684	<link to="IProgress::waitForCompletion" /> or similar calls to wait for
2685	completion.
2686
2687	As with all <link to="ISession" /> objects, it is recommended to call
2688	<link to="ISession::close" /> on the local session object once openRemoteSession()
2689	has been called. However, the session's state (see <link to="ISession::state" />)
2690	will not return to "Closed" until the remote session has also closed (i.e.
2691	until the VM is no longer running). In that case, however, the state of
2692	the session will automatically change back to "Closed".
2693
2694	Currently supported session types (values of the @a type
2695	argument) are:
2696	<ul>
2697	<li><tt>"gui"</tt>: VirtualBox Qt GUI session</li>
2698	<li><tt>"vrdp"</tt>: VirtualBox VRDP Server session</li>
2699	<li><tt>"sdl"</tt>: VirtualBox SDL GUI session</li>
2700	</ul>
2701
2702	The @a environment argument is a string containing definitions of
2703	environment variables in the following format:
2704	@code
2705	NAME[=VALUE]\n
2706	NAME[=VALUE]\n
2707	...
2708	@endcode
2709	where <tt>\\n</tt> is the new line character. These environment
2710	variables will be appended to the environment of the VirtualBox server
2711	process. If an environment variable exists both in the server process
2712	and in this list, the value from this list takes precedence over the
2713	server's variable. If the value of the environment variable is
2714	omitted, this variable will be removed from the resulting environment.
2715	If the environment string is @c null or empty, the server environment
2716	is inherited by the started process as is.

2850	Blocks the caller until any of the properties represented by the
2851	@a what argument changes the value or until the given timeout interval
2852	expires.
2853
2854	The @a what argument is a comma separated list of property masks that
2855	describe properties the caller is interested in. The property mask is
2856	a string in the following format:
2857
2858	<pre>
2859	[[group.]subgroup.]name
2860	</pre>
2861
2862	where @c name is the property name and @c group, @c subgroup are zero
2863	or more property group specifiers. Each element (group or name) in
2864	the property mask may be either a Latin string or an asterisk symbol
2865	(@c "*") which is used to match any string for the given element. A
2866	property mask that doesn't contain asterisk symbols represents a
2867	single fully qualified property name.
2868
2869	Groups in the fully qualified property name go from more generic (the
2870	left-most part) to more specific (the right-most part). The first
2871	element is usually a name of the object the property belongs to. The
2872	second element may be either a property name, or a child object name,
2873	or an index if the preceding element names an object which is one of
2874	many objects of the same type. This way, property names form a
2875	hierarchy of properties. Here are some examples of property names:
2876
2877	<table>
2878	<tr>
2879	<td><tt>VirtualBox.version</tt></td>
2880	<td><link to="IVirtualBox::version"/> property</td>
2881	</tr>
2882	<tr>
2883	<td><tt>Machine.<UUID>.name</tt></td>
2884	<td><link to="IMachine::name"/> property of the machine with the
2885	given UUID</td>
2886	</tr>
2887	</table>
2888
2889	Most property names directly correspond to the properties of objects
2890	(components) provided by the VirtualBox library and may be used to
2891	track changes to these properties. However, there may be
2892	pseudo-property names that don't correspond to any existing object's
2893	property directly, as well as there may be object properties that
2894	don't have a corresponding property name that is understood by this
2895	method, and therefore changes to such properties cannot be
2896	tracked. See individual object's property descriptions to get a
2897	fully qualified property name that can be used with this method (if
2898	any).
2899
2900	There is a special property mask @c "*" (i.e. a string consisting of a
2901	single asterisk symbol) that can be used to match all properties.
2902	Below are more examples of property masks:
2903
2904	<table>
2905	<tr>
2906	<td><tt>VirtualBox.*</tt></td>
2907	<td>Track all properties of the VirtualBox object</td>
2908	</tr>
2909	<tr>
2910	<td><tt>Machine.*.name</tt></td>

3189	<desc>
3190	Represents a platform-independent appliance in OVF format. An instance of this is returned
3191	by <link to="IVirtualBox::createAppliance" />, which can then be used to import and export
3192	appliances with VirtualBox.
3193
3194	The OVF standard suggests two different physical file formats:
3195
3196	<ol>
3197	<li>If the OVF is distributed as a set of files, then @a file must be a fully qualified
3198	path name to an existing OVF descriptor file with an <tt>.ovf</tt> file extension. If
3199	this descriptor file references other files, as OVF appliances distributed as a set of
3200	files most likely do, those files must be in the same directory as the descriptor file.</li>
3201
3202	<li>If the OVF is distributed as a single file, it must be in TAR format and have the
3203	<tt>.ova</tt> file extension. This TAR file must then contain at least the OVF descriptor
3204	files and optionally other files.
3205
3206	At this time, VirtualBox does not not yet support the packed (TAR) variant; support will
3207	be added with a later version.</li>
3208	</ol>
3209
3210	<b>Importing</b> an OVF appliance into VirtualBox as instances of
3211	<link to="IMachine" /> involves the following sequence of API calls:
3212
3213	<ol>
3214	<li>Call <link to="IVirtualBox::createAppliance" />. This will create an empty IAppliance object.
3215	</li>
3216
3217	<li>On the new object, call <link to="#read" /> with the full path of the OVF file you
3218	would like to import. So long as this file is syntactically valid, this will succeed
3219	and return an instance of IAppliance that contains the parsed data from the OVF file.
3220	</li>
3221
3222	<li>Next, call <link to="#interpret" />, which analyzes the OVF data and sets up the
3223	contents of the IAppliance attributes accordingly. These can be inspected by a
3224	VirtualBox front-end such as the GUI, and the suggestions can be displayed to the
3225	user. In particular, the <link to="#virtualSystemDescriptions" /> array contains
3226	instances of <link to="IVirtualSystemDescription" /> which represent the virtual
3227	systems in the OVF, which in turn describe the virtual hardware prescribed by the
3228	OVF (network and hardware adapters, virtual disk images, memory size and so on).
3229	The GUI can then give the user the option to confirm and/or change these suggestions.
3230	</li>
3231
3232	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
3233	virtual system to override the suggestions made by the interpret() routine.
3234	</li>
3235
3236	<li>Finally, call <link to="#importMachines" /> to create virtual machines in
3237	VirtualBox as instances of <link to="IMachine" /> that match the information in the
3238	virtual system descriptions.
3239	</li>
3240	</ol>
3241
3242	<b>Exporting</b> VirtualBox machines into an OVF appliance involves the following steps:
3243
3244	<ol>
3245	<li>As with importing, first call <link to="IVirtualBox::createAppliance" /> to create
3246	an empty IAppliance object.
3247	</li>
3248
3249	<li>For each machine you would like to export, call <link to="IMachine::export" />
3250	with the IAppliance object you just created. This creates an instance of
3251	<link to="IVirtualSystemDescription" /> inside the appliance.
3252	</li>
3253
3254	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
3255	virtual system to override the suggestions made by the export() routine.
3256	</li>
3257
3258	<li>Finally, call <link to="#write" /> with a path specification to have the OVF
3259	file written.</li>
3260	</ol>
3261
3262	</desc>
3263
3264	<attribute name="path" type="wstring" readonly="yes">
3265	<desc>Path to the main file of the OVF appliance, which is either the <tt>.ovf</tt> or

3498
3499	<ul>
3500	<li>
3501	"OS": the guest operating system type. There must be exactly one such array item on import. The
3502	corresponding item in aVBoxValues[] contains the suggested guest operating system for VirtualBox.
3503	This will be one of the values listed in <link to="IVirtualBox::guestOSTypes" />. The corresponding
3504	item in aOvfValues[] will contain a numerical value that described the operating system in the OVF.
3505	</li>
3506	<li>
3507	"Name": the name to give to the new virtual machine. There can be at most one such array item;
3508	if none is present on import, then an automatic name will be created from the operating system
3509	type. The correponding item im aOvfValues[] will contain the suggested virtual machine name
3510	from the OVF file, and aVBoxValues[] will contain a suggestion for a unique VirtualBox
3511	<link to="IMachine" /> name that does not exist yet.
3512	</li>
3513	<li>
3514	"Description": an arbitrary description.
3515	</li>
3516	<li>
3517	"License": the EULA section from the OVF, if present. It is the responsibility of the calling
3518	code to display such a license for agreement; the Main API does not enforce any such policy.
3519	</li>
3520	<li>
3521	Miscellaneous: reserved for future use.
3522	</li>
3523	<li>
3524	"CPU": the number of CPUs. There can be at most one such item, which will presently be ignored.
3525	</li>
3526	<li>
3527	"Memory": the amount of guest RAM, in bytes. There can be at most one such array item; if none
3528	is present on import, then VirtualBox will set a meaningful default based on the operating system
3529	type.
3530	</li>
3531	<li>
3532	"HarddiskControllerIDE": an IDE hard disk controller. There can be at most one such item. This
3533	has no value in aOvfValues[] or aVBoxValues[].
3534	The matching item in the aRefs[] array will contain an integer that items of the "Harddisk"
3535	type can use to specify which hard disk controller a virtual disk should be connected to.
3536	</li>
3537	<li>
3538	"HarddiskControllerSATA": an SATA hard disk controller. There can be at most one such item. This
3539	has no value in aOvfValues[] or aVBoxValues[].
3540	The matching item in the aRefs[] array will be used as with IDE controllers (see above).
3541	</li>
3542	<li>
3543	"HarddiskControllerSCSI": a SCSI hard disk controller. There can be at most one such item.
3544	The items in aOvfValues[] and aVBoxValues[] will either be "LsiLogic" or "BusLogic".
3545	The matching item in the aRefs[] array will be used as with IDE controllers (see above).
3546	</li>
3547	<li>
3548	"HardDiskImage": a virtual hard disk, most probably as a reference to an image file. There can be an
3549	arbitrary number of these items, one for each virtual disk image that accompanies the OVF.
3550
3551	The array item in aOvfValues[] will contain the file specification from the OVF file (without
3552	a path since the image file should be in the same location as the OVF file itself), whereas the
3553	item in aVBoxValues[] will contain a qualified path specification to where VirtualBox uses the
3554	hard disk image. This means that on import the image will be copied and converted from the
3555	"ovf" location to the "vbox" location; on export, this will be handled the other way round.
3556	On import, the target image will also be registered with VirtualBox.
3557
3558	The matching item in the aExtraConfigValues[] array must contain a string of the following
3559	format: "controller=<index>;channel=<c>"
3560	In this string, <index> must be an integer specifying the hard disk controller to connect
3561	the image to. That number must be the index of an array item with one of the hard disk controller
3562	types (HarddiskControllerSCSI, HarddiskControllerSATA, HarddiskControllerIDE).
3563	In addition, <c> must specify the channel to use on that controller. For IDE controllers,
3564	this can range from 0-3 (which VirtualBox will interpret as primary master, primary slave, secondary master and
3565	secondary slave. For SATA and SCSI controllers, the channel can range from 0-29.
3566	</li>
3567	<li>
3568	"CDROM": a virtual CD-ROM drive. The matching item in aExtraConfigValue[] contains the same
3569	attachment information as with "HardDiskImage" items.
3570	</li>
3571	<li>
3572	"CDROM": a virtual floppy drive. The matching item in aExtraConfigValue[] contains the same
3573	attachment information as with "HardDiskImage" items.
3574	</li>
3575	<li>
3576	"NetworkAdapter": a network adapter. The array item in aVBoxValues[] will specify the hardware
3577	for the network adapter, whereas the array item in aExtraConfigValues[] will have a string
3578	of the "type=<X>" format, where <X> must be either "NAT" or "Bridged".
3579	</li>
3580	<li>
3581	"USBController": a USB controller. There can be at most one such item. If and only if such an
3582	item ispresent, USB support will be enabled for the new virtual machine.

4162	<desc>
4163	The IMachine interface represents a virtual machine, or guest, created
4164	in VirtualBox.
4165
4166	This interface is used in two contexts. First of all, a collection of
4167	objects implementing this interface is stored in the
4168	<link to="IVirtualBox::machines"/> attribute which lists all the virtual
4169	machines that are currently registered with this VirtualBox
4170	installation. Also, once a session has been opened for the given virtual
4171	machine (e.g. the virtual machine is running), the machine object
4172	associated with the open session can be queried from the session object;
4173	see <link to="ISession"/> for details.
4174
4175	The main role of this interface is to expose the settings of the virtual
4176	machine and provide methods to change various aspects of the virtual
4177	machine's configuration. For machine objects stored in the
4178	<link to="IVirtualBox::machines"/> collection, all attributes are
4179	read-only unless explicitly stated otherwise in individual attribute
4180	and method descriptions. In order to change a machine setting, a session
4181	for this machine must be opened using one of
4182	<link to="IVirtualBox::openSession"/>,
4183	<link to="IVirtualBox::openRemoteSession"/> or
4184	<link to="IVirtualBox::openExistingSession"/> methods. After the
4185	session has been successfully opened, a mutable machine object needs to
4186	be queried from the session object and then the desired settings changes
4187	can be applied to the returned object using IMachine attributes and
4188	methods. See the <link to="ISession"/> interface description for more
4189	information about sessions.
4190
4191	Note that IMachine does not provide methods to control virtual machine
4192	execution (such as start the machine, or power it down) -- these methods
4193	are grouped in a separate interface called <link to="IConsole" />.

4202	<attribute name="accessible" type="boolean" readonly="yes">
4203	<desc>
4204	Whether this virtual machine is currently accessible or not.
4205
4206	A machine is always deemed accessible unless it is registered <i>and</i>
4207	its settings file cannot be read or parsed (either because the file itself
4208	is unavailable or has invalid XML contents).
4209
4210	Every time this property is read, the accessibility state of
4211	this machine is re-evaluated. If the returned value is @c false,
4212	the <link to="#accessError"/> property may be used to get the
4213	detailed error information describing the reason of
4214	inaccessibility, including XML error messages.
4215
4216	When the machine is inaccessible, only the following properties
4217	can be used on it:
4218	<ul>
4219	<li><link to="#parent"/></li>
4220	<li><link to="#id"/></li>
4221	<li><link to="#settingsFilePath"/></li>
4222	<li><link to="#accessible"/></li>
4223	<li><link to="#accessError"/></li>
4224	</ul>
4225
4226	An attempt to access any other property or method will return
4227	an error.
4228
4229	The only possible action you can perform on an inaccessible
4230	machine is to unregister it using the
4231	<link to="IVirtualBox::unregisterMachine"/> call (or, to check
4232	for the accessibility state once more by querying this
4233	property).
4234
4235	<note>
4236	In the current implementation, once this property returns
4237	@c true, the machine will never become inaccessible
4238	later, even if its settings file cannot be successfully
4239	read/written any more (at least, until the VirtualBox
4240	server is restarted). This limitation may be removed in
4241	future releases.

4250
4251	Reading this property is only valid after the last call to
4252	<link to="#accessible"/> returned @c false (i.e. the
4253	machine is currently unaccessible). Otherwise, a @c null
4254	IVirtualBoxErrorInfo object will be returned.

4260	Name of the virtual machine.
4261
4262	Besides being used for human-readable identification purposes
4263	everywhere in VirtualBox, the virtual machine name is also used
4264	as a name of the machine's settings file and as a name of the
4265	subdirectory this settings file resides in. Thus, every time you
4266	change the value of this property, the settings file will be
4267	renamed once you call <link to="#saveSettings"/> to confirm the
4268	change. The containing subdirectory will be also renamed, but
4269	only if it has exactly the same name as the settings file
4270	itself prior to changing this property (for backward compatibility
4271	with previous API releases). The above implies the following
4272	limitations:
4273	<ul>
4274	<li>The machine name cannot be empty.</li>
4275	<li>The machine name can contain only characters that are valid
4276	file name characters according to the rules of the file
4277	system used to store VirtualBox configuration.</li>
4278	<li>You cannot have two or more machines with the same name
4279	if they use the same subdirectory for storing the machine
4280	settings files.</li>
4281	<li>You cannot change the name of the machine if it is running,
4282	or if any file in the directory containing the settings file
4283	is being used by another running machine or by any other
4284	process in the host operating system at a time when
4285	<link to="#saveSettings"/> is called.
4286	</li>
4287	</ul>
4288	If any of the above limitations are hit, <link to="#saveSettings"/>
4289	will return an appropriate error message explaining the exact
4290	reason and the changes you made to this machine will not be
4291	saved.
4292	<note>
4293	For "legacy" machines created using the
4294	<link to="IVirtualBox::createLegacyMachine"/> call,
4295	the above naming limitations do not apply because the
4296	machine name does not affect the settings file name.
4297	The settings file name remains the same as it was specified
4298	during machine creation and never changes.

4733	Attaches a device and optionally mounts a medium to the given storage
4734	controller (<link to="IStorageController" />, identified by @a name),
4735	at the indicated port and device.
4736
4737	This method is intended for managing storage devices in general (it works
4738	for both fixed and removable media). For storage devices supporting removable
4739	media (such as DVDs and floppies), you can also use <link to="IMedium::mountMedium"/>
4740	for changing the media while the machine is running.
4741
4742	For the IDE bus, the @a controllerPort parameter can be either
4743	@c 0 or @c 1, to specify the primary or secondary IDE controller,
4744	respectively. For each of these, @a device can then be either @c 0 or @c 1,
4745	to specify the master or the slave device, respectively. (In the
4746	default configuration of virtual machines, the secondary master is
4747	used for a CD/DVD drive.)
4748
4749	For an SATA controller, @a controllerPort must be a number ranging
4750	from @c 0 to @c 29. For a SCSI controller, @a controllerPort must
4751	be a number ranging from @c 0 to @c 15.
4752
4753	For both SCSI and SATA, the @a device parameter is unused and must
4754	be @c 0.
4755
4756	For fixed media such as hard disks, the given medium identifier cannot
4757	be a zero UUID. It may be a zero UUID for removable media such as DVDs
4758	and floppies.
4759
4760	After calling this returns successfully, a new instance of
4761	<link to="IMediumAttachment"/> will appear in the machine's list of medium
4762	attachments (<link to="IMachine::mediumAttachments"/>).
4763
4764	The specified device slot must not have a device attached to it,
4765	or this method will fail.

4774	</note>
4775	<note>
4776	If the medium is being attached indirectly, a new differencing medium
4777	will implicitly be created for it and attached instead. If the

5932	This interface is used by a client of the Main API that need to
5933	be notified of events. For example, a graphical user interface
5934	can use this to learn about machine state changes so they can
5935	update the list of virtual machines without having to rely
5936	on polling.
5937
5938	Whenever relevant events occur in VirtualBox, the callbacks in
5939	objects of this interface are called. In order for this to be
5940	useful, a client needs to create its own subclass that implements
5941	this interface in which the methods for the relevant callbacks
5942	are overridden. An instance of this subclass interface can then
5943	be passed to <link to="IConsole::registerCallback" />.

5984
5985	The @a shape buffer contains a 1-bpp (bits per pixel) AND mask
5986	followed by a 32-bpp XOR (color) mask.
5987
5988	For pointers without alpha channel the XOR mask pixels are 32
5989	bit values: (lsb)BGR0(msb). For pointers with alpha channel
5990	the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
5991
5992	An AND mask is used for pointers with alpha channel, so if the
5993	callback does not support alpha, the pointer could be
5994	displayed as a normal color pointer.
5995
5996	The AND mask is a 1-bpp bitmap with byte aligned scanlines. The
5997	size of the AND mask therefore is <tt>cbAnd = (width + 7) / 8 *
5998	height</tt>. The padding bits at the end of each scanline are
5999	undefined.
6000
6001	The XOR mask follows the AND mask on the next 4-byte aligned
6002	offset: <tt>uint8_t *pXor = pAnd + (cbAnd + 3) & ~3</tt>.
6003	Bytes in the gap between the AND and the XOR mask are undefined.
6004	The XOR mask scanlines have no gap between them and the size of
6005	the XOR mask is: <tt>cXor = width * 4 * height</tt>.

6008	If @a shape is 0, only the pointer visibility is changed.

6186	<desc>
6187	Notification when an error happens during the virtual
6188	machine execution.
6189
6190	There are three kinds of runtime errors:
6191	<ul>
6192	<li><i>fatal</i></li>
6193	<li><i>non-fatal with retry</i></li>
6194	<li><i>non-fatal warnings</i></li>
6195	</ul>
6196
6197	<b>Fatal</b> errors are indicated by the @a fatal parameter set
6198	to @c true. In case of fatal errors, the virtual machine
6199	execution is always paused before calling this notification, and
6200	the notification handler is supposed either to immediately save
6201	the virtual machine state using <link to="IConsole::saveState"/>
6202	or power it off using <link to="IConsole::powerDown"/>.
6203	Resuming the execution can lead to unpredictable results.
6204
6205	<b>Non-fatal</b> errors and warnings are indicated by the
6206	@a fatal parameter set to @c false. If the virtual machine
6207	is in the Paused state by the time the error notification is
6208	received, it means that the user can <i>try to resume</i> the machine
6209	execution after attempting to solve the problem that caused the
6210	error. In this case, the notification handler is supposed
6211	to show an appropriate message to the user (depending on the
6212	value of the @a id parameter) that offers several actions such
6213	as <i>Retry</i>, <i>Save</i> or <i>Power Off</i>. If the user
6214	wants to retry, the notification handler should continue
6215	the machine execution using the <link to="IConsole::resume"/>
6216	call. If the machine execution is not Paused during this
6217	notification, then it means this notification is a <i>warning</i>
6218	(for example, about a fatal condition that can happen very soon);
6219	no immediate action is required from the user, the machine
6220	continues its normal execution.
6221
6222	Note that in either case the notification handler
6223	<b>must not</b> perform any action directly on a thread
6224	where this notification is called. Everything it is allowed to
6225	do is to post a message to another thread that will then talk
6226	to the user and take the corresponding action.
6227
6228	Currently, the following error identifiers are known:
6229	<ul>
6230	<li><tt>"HostMemoryLow"</tt></li>
6231	<li><tt>"HostAudioNotResponding"</tt></li>
6232	<li><tt>"VDIStorageFull"</tt></li>

6999	<desc>
7000	Starts deleting the specified snapshot asynchronously.
7001	See <link to="ISnapshot" /> for an introduction to snapshots.
7002
7003	The execution state and settings of the associated machine stored in
7004	the snapshot will be deleted. The contents of all differencing media of
7005	this snapshot will be merged with the contents of their dependent child
7006	media to keep the medium chain valid (in other words, all changes
7007	represented by media being discarded will be propagated to their child
7008	medium). After that, this snapshot's differencing medium will be
7009	deleted. The parent of this snapshot will become a new parent for all
7010	its child snapshots.
7011
7012	If the deleted snapshot is the current one, its parent snapshot will
7013	become a new current snapshot. The current machine state is not directly
7014	affected in this case, except that currently attached differencing
7015	media based on media of the discarded snapshot will be also merged as
7016	described above.
7017
7018	If the deleted snapshot is the first or current snapshot, then the
7019	respective IMachine attributes will be adjusted. Deleting the current
7020	snapshot will also implicitly call <link to="IMachine::saveSettings"/>
7021	to make all current machine settings permanent.
7022
7023	Deleting a snapshot has the following preconditions:
7024
7025	<ul>
7026	<li>Child media of all normal media of the discarded snapshot
7027	must be accessible (see <link to="IMedium::state"/>) for this
7028	operation to succeed. In particular, this means that all virtual
7029	machines, whose media are directly or indirectly based on the
7030	media of discarded snapshot, must be powered off.</li>
7031
7032	<li>You cannot delete the snapshot if a medium attached to it has
7033	more than once child medium (differencing images) because otherwise
7034	merging would be impossible. This might be the case if there is
7035	more than one child snapshot or differencing images were created
7036	for other reason (e.g. implicitly because of multiple machine
7037	attachments).</li>
7038	</ul>
7039
7040
7041	The virtual machine's <link to="IMachine::state">state</link> is changed to "DeletingSnapshot"
7042	while this operation is in progress.
7043
7044	<note>
7045	Merging medium contents can be very time and disk space
7046	consuming, if these media are big in size and have many
7047	children. However, if the snapshot being discarded is the last
7048	(head) snapshot on the branch, the operation will be rather
7049	quick.

7929	(<link to="IMediumFormat::id"/>) used in other API calls like
7930	<link to="IVirtualBox::createHardDisk"/> to refer to a particular

7951	Identifier of the default medium format used by VirtualBox.
7952
7953	The medium format set by this attribute is used by VirtualBox
7954	when the medium format was not specified explicitly. One example is
7955	<link to="IVirtualBox::createHardDisk"/> with the empty
7956	format argument. A more complex example is implicit creation of
7957	differencing media when taking a snapshot of a virtual machine:
7958	this operation will try to use a format of the parent medium first
7959	and if this format does not support differencing media the default
7960	format specified by this argument will be used.
7961
7962	The list of supported medium formats may be obtained by the
7963	<link to="#mediaFormats"/> call. Note that the default medium

8013
8014	As opposed to <link to="ISystemProperties::remoteDisplayAuthLibrary" />,
8015	there is no per-VM setting for this, as the webservice is a global
8016	resource (if it is running). Only for this setting (for the webservice),
8017	setting this value to a literal <tt>"null"</tt> string disables authentication,
8018	meaning that <link to="IWebsessionManager::logon" /> will always succeed,
8019	no matter what user name and password are supplied.
8020
8021	The initial value of this property is <tt>"VRDPAuth"</tt>,
8022	meaning that the webservice will use the same authentication
8023	library that is used by default for VBoxVRDP (again, see

8302	The IProgress interface is used to track and control
8303	asynchronous tasks within VirtualBox.
8304
8305	An instance of this is returned every time VirtualBox starts
8306	an asynchronous task (in other words, a separate thread) which
8307	continues to run after a method call returns. For example,
8308	<link to="IConsole::saveState" />, which saves the state of
8309	a running virtual machine, can take a long time to complete.
8310	To be able to display a progress bar, a user interface such as
8311	the VirtualBox graphical user interface can use the IProgress
8312	object returned by that method.
8313
8314	Note that IProgress is a "read-only" interface in the sense
8315	that only the VirtualBox internals behind the Main API can
8316	create and manipulate progress objects, whereas client code
8317	can only use the IProgress object to monitor a task's
8318	progress and, if <link to="#cancelable" /> is @c true,
8319	cancel the task by calling <link to="#cancel" />.
8320
8321	A task represented by IProgress consists of either one or
8322	several sub-operations that run sequentially, one by one (see
8323	<link to="#operation" /> and <link to="#operationCount" />).
8324	Every operation is identified by a number (starting from 0)
8325	and has a separate description.
8326
8327	You can find the individual percentage of completion of the current
8328	operation in <link to="#operationPercent" /> and the
8329	percentage of completion of the task as a whole
8330	in <link to="#percent" />.
8331
8332	Similarly, you can wait for the completion of a particular

8502	<interface
8503	name="ISnapshot" extends="$unknown"
8504	uuid="1a2d0551-58a4-4107-857e-ef414fc42ffc"
8505	wsmap="managed"
8506	>
8507	<desc>
8508	The ISnapshot interface represents a snapshot of the virtual
8509	machine.
8510
8511	Together with the differencing media that are created
8512	when a snapshot is taken, a machine can be brought back to
8513	the exact state it was in when the snapshot was taken.
8514
8515	The ISnapshot interface has no methods, only attributes; snapshots
8516	are controlled through methods of the <link to="IConsole" /> interface
8517	which also manage the media associated with the snapshot.
8518	The following operations exist:
8519
8520	<ul>
8521	<li><link to="IConsole::takeSnapshot"/>: creates a new snapshot
8522	by creating new, empty differencing images for the machine's
8523	media and saving the VM settings and (if the VM is running)
8524	the current VM state in the snapshot.
8525
8526	The differencing images will then receive all data written to
8527	the machine's media, while their parent (base) images
8528	remain unmodified after the snapshot has been taken (see
8529	<link to="IMedium" /> for details about differencing images).
8530	This simplifies restoring a machine to the state of a snapshot:
8531	only the differencing images need to be deleted.
8532
8533	The current machine state is not changed by taking a snapshot.
8534	If the machine is running, it will resume execution after the
8535	snapshot has been taken.
8536	</li>
8537
8538	<li><link to="IConsole::restoreSnapshot"/>: this goes back to
8539	a previous snapshot. This resets the machine's state to that of
8540	the previous snapshot by deleting the differencing image of each
8541	of the machine's media and setting the machine's settings
8542	and state to the state that was saved in the snapshot (if any).
8543
8544	This destroys the machine's current state.
8545	</li>
8546
8547	<li><link to="IConsole::deleteSnapshot"/>: deletes a snapshot
8548	without affecting the current machine state.
8549
8550	This does not change the machine, but instead frees the resources
8551	allocated when the snapshot was taken: the settings and machine state
8552	is deleted (if any), and the snapshot's differencing image for each
8553	of the machine's media gets merged with its parent image.
8554
8555	Neither the current machine state nor other snapshots are affected
8556	by this operation, except that parent media will be modified
8557	to contain the disk data associated with the snapshot being deleted.
8558	</li>
8559	</ul>
8560
8561	Each snapshot contains the settings of the virtual machine (hardware
8562	configuration etc.). In addition, if the machine was running when the
8563	snapshot was taken (<link to="IMachine::state"/> is <link to="MachineState_Running"/>),
8564	the current VM state is saved in the snapshot (similarly to what happens
8565	when a VM's state is saved). The snapshot is then said to
8566	be <i>online</i> because when restoring it, the VM will be running.
8567
8568	If the machine is saved (<link to="MachineState_Saved"/>), the snapshot
8569	receives a copy of the execution state file (<link to="IMachine::stateFilePath"/>).
8570
8571	Otherwise, if the machine was not running (<link to="MachineState_PoweredOff"/>
8572	or <link to="MachineState_Aborted"/>), the snapshot is <i>offline</i>;
8573	it then contains a so-called "zero execution state", representing a
8574	machine that is powered off.
8575
8576	<h3>Snapshot branches and the "current" snapshot</h3>
8577
8578	Snapshots can be chained, whereby every next snapshot is based on the
8579	previous one. This chaining is related to medium branching
8580	(see the <link to="IMedium"/> description) in that every time
8581	a new snapshot is created, a new differencing medium is implicitly
8582	created for all normal media attached to the machine.
8583
8584	Each virtual machine has a "current snapshot", identified by
8585	<link to="IMachine::currentSnapshot"/>. Presently, this is always set
8586	to the last snapshot in the chain. In a future version of VirtualBox,
8587	it will be possible to reset a machine's current state to that of an
8588	earlier snapshot without discarding the current state so that it will be
8589	possible to create alternative snapshot paths in a snapshot tree.
8590
8591	In the current implementation, multiple snapshot branches within one
8592	virtual machine are not allowed. Every machine has a single branch,
8593	and <link to="IConsole::takeSnapshot"/> operation adds a new
8594	snapshot to the top of that branch.

8835	<desc>
8836	The IMedium interface represents virtual storage for a machine's
8837	hard disks, CD/DVD or floppy drives. It will typically represent
8838	a disk image on the host, for example a VDI or VMDK file representing
8839	a virtual hard disk, or an ISO or RAW file representing virtual
8840	removable media, but can also point to a network location (e.g.
8841	for iSCSI targets).
8842
8843	Instances of IMedium are connected to virtual machines by way of
8844	medium attachments (see <link to="IMediumAttachment" />), which link
8845	the storage medium to a particular device slot of a storage controller
8846	of the virtual machine.
8847	In the VirtualBox API, virtual storage is therefore always represented
8848	by the following chain of object links:
8849
8850	<ul>
8851	<li><link to="IMachine::storageControllers"/> contains an array of
8852	storage controllers (IDE, SATA, SCSI or a floppy controller;
8853	these are instances of <link to="IStorageController"/>).</li>
8854	<li><link to="IMachine::mediumAttachments"/> contains an array of
8855	medium attachments (instances of <link to="IMediumAttachment"/>),
8856	each containing a storage controller from the above array, a
8857	port/device specification, and an instance of IMedium representing
8858	the medium storage (image file).
8859
8860	For removable media, the storage medium is optional; a medium
8861	attachment with no medium represents a CD/DVD or floppy drive
8862	with no medium inserted. By contrast, hard disk attachments
8863	will always have an IMedium object attached.</li>
8864	<li>Each IMedium in turn points to a storage unit (such as a file
8865	on the host computer or a network resource) that holds actual
8866	data. This location is represented by the <link to="#location"/>
8867	attribute.</li>
8868	</ul>
8869
8870	Existing media are opened using the following methods, depending on the
8871	media type:
8872	<ul>
8873	<li><link to="IVirtualBox::openHardDisk"/></li>
8874	<li><link to="IVirtualBox::openDVDImage"/></li>
8875	<li><link to="IVirtualBox::openFloppyImage"/></li>
8876	</ul>
8877
8878	New hard disk media can be created with the VirtualBox API using the
8879	<link to="IVirtualBox::createHardDisk"/> method.
8880
8881	CD/DVD and floppy images (ISO and RAW files) are usually created outside
8882	VirtualBox, e.g. by storing a copy of the real medium of the corresponding
8883	type in a regular file.
8884
8885	Only for CD/DVDs and floppies, an IMedium instance can also represent a host
8886	drive; in that case the <link to="#id" /> attribute contains the UUID of
8887	one of the drives in <link to="IHost::DVDDrives" /> or <link to="IHost::floppyDrives" />.
8888
8889	<h3>Known media</h3>
8890
8891	When an existing medium is opened for the first time, it is automatically
8892	remembered by the given VirtualBox installation or, in other words, becomes
8893	a <i>known medium</i>. Known media are stored in the media
8894	registry transparently maintained by VirtualBox and stored in settings
8895	files so that this registry is preserved when VirtualBox is not running.
8896
8897	Newly created virtual media are remembered only when the associated
8898	storage unit is actually created.
8899
8900	All known media can be enumerated using
8901	<link to="IVirtualBox::hardDisks"/>,
8902	<link to="IVirtualBox::DVDImages"/> and
8903	<link to="IVirtualBox::floppyImages"/> attributes. Individual media can be
8904	quickly found by UUID using <link to="IVirtualBox::getHardDisk"/>
8905	and similar methods or by location using
8906	<link to="IVirtualBox::findHardDisk"/> and similar methods.
8907
8908	Only known media can be attached to virtual machines.
8909
8910	Removing known media from the media registry is performed when the given
8911	medium is closed using the <link to="#close"/> method or when its
8912	associated storage unit is deleted.
8913
8914	<h3>Accessibility checks</h3>
8915
8916	VirtualBox defers media accessibility checks until the <link to="#refreshState" />
8917	method is called explicitly on a medium. This is done to make the VirtualBox object
8918	ready for serving requests as fast as possible and let the end-user
8919	application decide if it needs to check media accessibility right away or not.
8920
8921	As a result, when VirtualBox starts up (e.g. the VirtualBox
8922	object gets created for the first time), all known media are in the
8923	"Inaccessible" state, but the value of the <link to="#lastAccessError"/>
8924	attribute is an empty string because no actual accessibility check has
8925	been made yet.
8926
8927	After calling <link to="#refreshState" />, a medium is considered
8928	<i>accessible</i> if its storage unit can be read. In that case, the
8929	<link to="#state"/> attribute has a value of "Created". If the storage
8930	unit cannot be read (for example, because it is located on a disconnected
8931	network resource, or was accidentally deleted outside VirtualBox),
8932	the medium is considered <i>inaccessible</i>, which is indicated by the
8933	"Inaccessible" state. The exact reason why the medium is inaccessible can be
8934	obtained by reading the <link to="#lastAccessError"/> attribute.
8935
8936	<h3>Medium types</h3>
8937
8938	There are three types of medium behavior (see <link to="MediumType" />):
8939	"normal", "immutable" and "writethrough", represented by the
8940	<link to="#type"/> attribute. The type of the medium defines how the
8941	medium is attached to a virtual machine and what happens when a
8942	<link to="ISnapshot">snapshot</link> of the virtual machine with the
8943	attached medium is taken. At the moment DVD and floppy media are always
8944	of type "writethrough".
8945
8946	All media can be also divided in two groups: <i>base</i> media and
8947	<i>differencing</i> media. A base medium contains all sectors of the
8948	medium data in its own storage and therefore can be used independently.
8949	In contrast, a differencing mediun is a "delta" to some other medium and
8950	contains only those sectors which differ from that other medium, which is
8951	then called a <i>parent</i>. The differencing medium is said to be
8952	<i>linked to</i> that parent. The parent may be itself a differencing
8953	medium, thus forming a chain of linked media. The last element in that
8954	chain must always be a base medium. Note that several differencing
8955	media may be linked to the same parent medium.
8956
8957	Differencing media can be distinguished from base media by querying the
8958	<link to="#parent"/> attribute: base media do not have parents they would
8959	depend on, so the value of this attribute is always @c null for them.
8960	Using this attribute, it is possible to walk up the medium tree (from the
8961	child medium to its parent). It is also possible to walk down the tree
8962	using the <link to="#children"/> attribute.
8963
8964	Note that the type of all differencing media is "Normal"; all other
8965	values are meaningless for them. Base media may be of any type.
8966
8967	<h3>Creating hard disks</h3>
8968
8969	New base hard disks are created using
8970	<link to="IVirtualBox::createHardDisk"/>. Existing hard disks are
8971	opened using <link to="IVirtualBox::openHardDisk"/>. Differencing hard
8972	disks are usually implicitly created by VirtualBox when needed but may
8973	also be created explicitly using <link to="#createDiffStorage"/>.
8974
8975	After the hard disk is successfully created (including the storage unit)
8976	or opened, it becomes a known hard disk (remembered in the internal media
8977	registry). Known hard disks can be attached to a virtual machine, accessed
8978	through <link to="IVirtualBox::getHardDisk"/> and
8979	<link to="IVirtualBox::findHardDisk"/> methods or enumerated using the
8980	<link to="IVirtualBox::hardDisks"/> array (only for base hard disks).
8981
8982	The following methods, besides <link to="IMedium::close"/>,
8983	automatically remove the hard disk from the media registry:
8984	<ul>
8985	<li><link to="#deleteStorage"/></li>
8986	<li><link to="#mergeTo"/></li>
8987	</ul>
8988
8989	If the storage unit of the hard disk is a regular file in the host's
8990	file system then the rules stated in the description of the
8991	<link to="IMedium::location"/> attribute apply when setting its value. In
8992	addition, a plain file name without any path may be given, in which case
8993	the <link to="ISystemProperties::defaultHardDiskFolder"> default hard disk
8994	folder</link> will be prepended to it.
8995
8996	<h4>Automatic composition of the file name part</h4>
8997
8998	Another extension to the <link to="IMedium::location"/> attribute is that
8999	there is a possibility to cause VirtualBox to compose a unique value for
9000	the file name part of the location using the UUID of the hard disk. This
9001	applies only to hard disks in <link to="MediumState_NotCreated"/> state,
9002	e.g. before the storage unit is created, and works as follows. You set the
9003	value of the <link to="IMedium::location"/> attribute to a location
9004	specification which only contains the path specification but not the file
9005	name part and ends with either a forward slash or a backslash character.
9006	In response, VirtualBox will generate a new UUID for the hard disk and
9007	compose the file name using the following pattern:
9008	<pre>
9009	<path>/{<uuid>}.<ext>
9010	</pre>
9011	where <tt><path></tt> is the supplied path specification,
9012	<tt><uuid></tt> is the newly generated UUID and <tt><ext></tt>
9013	is the default extension for the storage format of this hard disk. After
9014	that, you may call any of the methods that create a new hard disk storage
9015	unit and they will use the generated UUID and file name.
9016
9017	<h3>Attaching Hard Disks</h3>
9018
9019	Hard disks are attached to virtual machines using the
9020	<link to="IMachine::attachDevice"/> method and detached using the
9021	<link to="IMachine::detachDevice"/> method. Depending on their
9022	<link to="#type"/>, hard disks are attached either
9023	<i>directly</i> or <i>indirectly</i>.
9024
9025	When a hard disk is being attached directly, it is associated with the
9026	virtual machine and used for hard disk operations when the machine is
9027	running. When a hard disk is being attached indirectly, a new differencing
9028	hard disk linked to it is implicitly created and this differencing hard
9029	disk is associated with the machine and used for hard disk operations.
9030	This also means that if <link to="IMachine::attachDevice"/> performs
9031	a direct attachment then the same hard disk will be returned in response
9032	to the subsequent <link to="IMachine::getMedium"/> call; however if
9033	an indirect attachment is performed then
9034	<link to="IMachine::getMedium"/> will return the implicitly created
9035	differencing hard disk, not the original one passed to <link
9036	to="IMachine::attachDevice"/>. In detail:
9037
9038	<ul>
9039	<li><b>Normal base</b> hard disks that do not have children (i.e.
9040	differencing hard disks linked to them) and that are not already
9041	attached to virtual machines in snapshots are attached <b>directly</b>.
9042	Otherwise, they are attached <b>indirectly</b> because having
9043	dependent children or being part of the snapshot makes it impossible
9044	to modify hard disk contents without breaking the integrity of the
9045	dependent party. The <link to="#readOnly"/> attribute allows to
9046	quickly determine the kind of the attachment for the given hard
9047	disk. Note that if a normal base hard disk is to be indirectly
9048	attached to a virtual machine with snapshots then a special
9049	procedure called <i>smart attachment</i> is performed (see below).</li>
9050	<li><b>Normal differencing</b> hard disks are like normal base hard disks:
9051	they are attached <b>directly</b> if they do not have children and are
9052	not attached to virtual machines in snapshots, and <b>indirectly</b>
9053	otherwise. Note that the smart attachment procedure is never performed
9054	for differencing hard disks.</li>
9055	<li><b>Immutable</b> hard disks are always attached <b>indirectly</b> because
9056	they are designed to be non-writable. If an immutable hard disk is
9057	attached to a virtual machine with snapshots then a special
9058	procedure called smart attachment is performed (see below).</li>
9059	<li><b>Writethrough</b> hard disks are always attached <b>directly</b>,
9060	also as designed. This also means that writethrough hard disks cannot
9061	have other hard disks linked to them at all.</li>
9062	</ul>
9063
9064	Note that the same hard disk, regardless of its type, may be attached to
9065	more than one virtual machine at a time. In this case, the machine that is
9066	started first gains exclusive access to the hard disk and attempts to
9067	start other machines having this hard disk attached will fail until the
9068	first machine is powered down.
9069
9070	Detaching hard disks is performed in a <i>deferred</i> fashion. This means
9071	that the given hard disk remains associated with the given machine after a
9072	successful <link to="IMachine::detachDevice"/> call until
9073	<link to="IMachine::saveSettings"/> is called to save all changes to
9074	machine settings to disk. This deferring is necessary to guarantee that
9075	the hard disk configuration may be restored at any time by a call to
9076	<link to="IMachine::discardSettings"/> before the settings
9077	are saved (committed).
9078
9079	Note that if <link to="IMachine::discardSettings"/> is called after
9080	indirectly attaching some hard disks to the machine but before a call to
9081	<link to="IMachine::saveSettings"/> is made, it will implicitly delete
9082	all differencing hard disks implicitly created by
9083	<link to="IMachine::attachDevice"/> for these indirect attachments.
9084	Such implicitly created hard disks will also be immediately deleted when
9085	detached explicitly using the <link to="IMachine::detachDevice"/>
9086	call if it is made before <link to="IMachine::saveSettings"/>. This
9087	implicit deletion is safe because newly created differencing hard
9088	disks do not contain any user data.
9089
9090	However, keep in mind that detaching differencing hard disks that were
9091	implicitly created by <link to="IMachine::attachDevice"/>
9092	before the last <link to="IMachine::saveSettings"/> call will
9093	<b>not</b> implicitly delete them as they may already contain some data
9094	(for example, as a result of virtual machine execution). If these hard
9095	disks are no more necessary, the caller can always delete them explicitly
9096	using <link to="#deleteStorage"/> after they are actually de-associated
9097	from this machine by the <link to="IMachine::saveSettings"/> call.
9098
9099	<h3>Smart Attachment</h3>
9100
9101	When normal base or immutable hard disks are indirectly attached to a
9102	virtual machine then some additional steps are performed to make sure the
9103	virtual machine will have the most recent "view" of the hard disk being
9104	attached. These steps include walking through the machine's snapshots
9105	starting from the current one and going through ancestors up to the first
9106	snapshot. Hard disks attached to the virtual machine in all
9107	of the encountered snapshots are checked whether they are descendants of
9108	the given normal base or immutable hard disk. The first found child (which
9109	is the differencing hard disk) will be used instead of the normal base or
9110	immutable hard disk as a parent for creating a new differencing hard disk
9111	that will be actually attached to the machine. And only if no descendants
9112	are found or if the virtual machine does not have any snapshots then the
9113	normal base or immutable hard disk will be used itself as a parent for
9114	this differencing hard disk.
9115
9116	It is easier to explain what smart attachment does using the
9117	following example:
9118	<pre>
9119	BEFORE attaching B.vdi: AFTER attaching B.vdi:
9120
9121	Snapshot 1 (B.vdi) Snapshot 1 (B.vdi)
9122	Snapshot 2 (D1->B.vdi) Snapshot 2 (D1->B.vdi)
9123	Snapshot 3 (D2->D1.vdi) Snapshot 3 (D2->D1.vdi)
9124	Snapshot 4 (none) Snapshot 4 (none)
9125	CurState (none) CurState (D3->D2.vdi)
9126
9127	NOT
9128	...
9129	CurState (D3->B.vdi)
9130	</pre>
9131	The first column is the virtual machine configuration before the base hard
9132	disk <tt>B.vdi</tt> is attached, the second column shows the machine after
9133	this hard disk is attached. Constructs like <tt>D1->B.vdi</tt> and similar
9134	mean that the hard disk that is actually attached to the machine is a
9135	differencing hard disk, <tt>D1.vdi</tt>, which is linked to (based on)
9136	another hard disk, <tt>B.vdi</tt>.
9137
9138	As we can see from the example, the hard disk <tt>B.vdi</tt> was detached
9139	from the machine before taking Snapshot 4. Later, after Snapshot 4 was
9140	taken, the user decides to attach <tt>B.vdi</tt> again. <tt>B.vdi</tt> has
9141	dependent child hard disks (<tt>D1.vdi</tt>, <tt>D2.vdi</tt>), therefore
9142	it cannot be attached directly and needs an indirect attachment (i.e.
9143	implicit creation of a new differencing hard disk). Due to the smart
9144	attachment procedure, the new differencing hard disk
9145	(<tt>D3.vdi</tt>) will be based on <tt>D2.vdi</tt>, not on
9146	<tt>B.vdi</tt> itself, since <tt>D2.vdi</tt> is the most recent view of
9147	<tt>B.vdi</tt> existing for this snapshot branch of the given virtual
9148	machine.
9149
9150	Note that if there is more than one descendant hard disk of the given base
9151	hard disk found in a snapshot, and there is an exact device, channel and
9152	bus match, then this exact match will be used. Otherwise, the youngest
9153	descendant will be picked up.
9154
9155	There is one more important aspect of the smart attachment procedure which
9156	is not related to snapshots at all. Before walking through the snapshots
9157	as described above, the backup copy of the current list of hard disk
9158	attachment is searched for descendants. This backup copy is created when
9159	the hard disk configuration is changed for the first time after the last
9160	<link to="IMachine::saveSettings"/> call and used by
9161	<link to="IMachine::discardSettings"/> to undo the recent hard disk
9162	changes. When such a descendant is found in this backup copy, it will be
9163	simply re-attached back, without creating a new differencing hard disk for
9164	it. This optimization is necessary to make it possible to re-attach the
9165	base or immutable hard disk to a different bus, channel or device slot
9166	without losing the contents of the differencing hard disk actually
9167	attached to the machine in place of it.

9354
9355	A medium is considered to be read-only when its contents cannot be
9356	modified without breaking the integrity of other parties that depend on
9357	this medium such as its child media or snapshots of virtual machines
9358	where this medium is attached to these machines. If there are no
9359	children and no such snapshots then there is no dependency and the
9360	medium is not read-only.

9362	The value of this attribute can be used to determine the kind of the
9363	attachment that will take place when attaching this medium to a

9365	be attached directly. If the value is @c true then the medium
9366	will be attached indirectly by creating a new differencing child
9367	medium for that. See the interface description for more information.

9459	<desc>
9460	If the current medium state (see <link to="MediumState"/>) is one of

9464
9465	For all other state values, this does not perform a refresh but returns
9466	the state only.
9467
9468	The refresh, if performed, may take a long time (several seconds or even
9469	minutes, depending on the storage unit location and format) because it performs an
9470	accessibility check of the storage unit. This check may cause a significant
9471	delay if the storage unit of the given medium is, for example, a file located
9472	on a network share which is not currently accessible due to connectivity
9473	problems. In that case, the call will not return until a timeout
9474	interval defined by the host OS for this operation expires. For this reason,
9475	it is recommended to never read this attribute on the main UI thread to avoid
9476	making the UI unresponsive.
9477
9478	If the last known state of the medium is "Created" and the accessibility
9479	check fails, then the state would be set to "Inaccessible", and
9480	<link to="#lastAccessError"/> may be used to get more details about the
9481	failure. If the state of the medium is "LockedRead", then it remains the
9482	same, and a non-empty value of <link to="#lastAccessError"/> will
9483	indicate a failed accessibility check in this case.

9523	<method name="lockRead">
9524	<desc>
9525	Locks this medium for reading.
9526
9527	A read lock is shared: many clients can simultaneously lock the
9528	same medium for reading unless it is already locked for writing (see
9529	<link to="#lockWrite"/>) in which case an error is returned.
9530
9531	When the medium is locked for reading, it cannot be modified
9532	from within VirtualBox. This means that any method that changes
9533	the properties of this medium or contents of the storage unit
9534	will return an error (unless explicitly stated otherwise). That
9535	includes an attempt to start a virtual machine that wants to
9536	write to the the medium.
9537
9538	When the virtual machine is started up, it locks for reading all
9539	media it uses in read-only mode. If some medium cannot be locked
9540	for reading, the startup procedure will fail.
9541	A medium is typically locked for reading while it is used by a running
9542	virtual machine but has a depending differencing image that receives
9543	the actual write operations. This way one base medium can have
9544	multiple child differencing images which can be written to
9545	simultaneously. Read-only media such as DVD and floppy images are
9546	also locked for reading only (so they can be in use by multiple
9547	machines simultaneously).
9548
9549	A medium is also locked for reading when it is the source of a
9550	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9551
9552	The medium locked for reading must be unlocked using the <link
9553	to="#unlockRead"/> method. Calls to <link to="#lockRead"/>
9554	can be nested and must be followed by the same number of paired
9555	<link to="#unlockRead"/> calls.
9556
9557	This method sets the medium state (see <link to="#state"/>) to
9558	"LockedRead" on success. The medium's previous state must be
9559	one of "Created", "Inaccessible" or "LockedRead".
9560
9561	Locking an inaccessible medium is not an error; this method performs
9562	a logical lock that prevents modifications of this medium through
9563	the VirtualBox API, not a physical file-system lock of the underlying
9564	storage unit.

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

9952	<method name="mergeTo">
9953	<desc>
9954	Starts merging the contents of this medium and all intermediate
9955	differencing media in the chain to the given target medium.
9956
9957	The target medium must be either a descendant of this medium or
9958	its ancestor (otherwise this method will immediately return a failure).
9959	It follows that there are two logical directions of the merge operation:
9960	from ancestor to descendant (<i>forward merge</i>) and from descendant to
9961	ancestor (<i>backward merge</i>). Let us consider the following medium
9962	chain:
9963
9964	<pre>Base <- Diff_1 <- Diff_2</pre>
9965
9966	Here, calling this method on the <tt>Base</tt> medium object with
9967	<tt>Diff_2</tt> as an argument will be a forward merge; calling it on
9968	<tt>Diff_2</tt> with <tt>Base</tt> as an argument will be a backward
9969	merge. Note that in both cases the contents of the resulting medium
9970	will be the same, the only difference is the medium object that takes
9971	the result of the merge operation. In case of the forward merge in the
9972	above example, the result will be written to <tt>Diff_2</tt>; in case of
9973	the backward merge, the result will be written to <tt>Base</tt>. In
9974	other words, the result of the operation is always stored in the target
9975	medium.
9976
9977	Upon successful operation completion, the storage units of all media in
9978	the chain between this (source) medium and the target medium, including
9979	the source medium itself, will be automatically deleted and the
9980	relevant medium objects (including this medium) will become
9981	uninitialized. This means that any attempt to call any of
9982	their methods or attributes will fail with the
9983	<tt>"Object not ready" (E_ACCESSDENIED)</tt> error. Applied to the above
9984	example, the forward merge of <tt>Base</tt> to <tt>Diff_2</tt> will
9985	delete and uninitialize both <tt>Base</tt> and <tt>Diff_1</tt> media.
9986	Note that <tt>Diff_2</tt> in this case will become a base medium
9987	itself since it will no longer be based on any other medium.
9988
9989	Considering the above, all of the following conditions must be met in
9990	order for the merge operation to succeed:
9991	<ul>
9992	<li>
9993	Neither this (source) medium nor any intermediate
9994	differencing medium in the chain between it and the target
9995	medium is attached to any virtual machine.
9996	</li>
9997	<li>
9998	Neither the source medium nor the target medium is an
9999	<link to="MediumType_Immutable"/> medium.
10000	</li>
10001	<li>
10002	The part of the medium tree from the source medium to the
10003	target medium is a linear chain, i.e. all medium in this
10004	chain have exactly one child which is the next medium in this
10005	chain. The only exception from this rule is the target medium in
10006	the forward merge operation; it is allowed to have any number of
10007	child media because the merge operation will not change its
10008	logical contents (as it is seen by the guest OS or by children).
10009	</li>
10010	<li>
10011	None of the involved media are in
10012	<link to="MediumState_LockedRead"/> or
10013	<link to="MediumState_LockedWrite"/> state.
10014	</li>
10015	</ul>
10016
10017	<note>
10018	This (source) medium and all intermediates will be placed to <link
10019	to="MediumState_Deleting"/> state and the target medium will be
10020	placed to <link to="MediumState_LockedWrite"/> state and for the

10036	Starts creating a clone of this medium in the format and at the

10038
10039	The target medium must be either in <link to="MediumState_NotCreated"/>

10041	<link to="MediumState_Created"/> state (i.e. created and not locked, and
10042	big enough to hold the data or else the copy will be partial). Upon
10043	successful completion, the cloned medium will contain exactly the
10044	same sector data as the medium being cloned, except that in the
10045	first case a new UUID for the clone will be randomly generated, and in
10046	the second case the UUID will remain unchanged.
10047
10048	The @a parent argument defines which medium will be the parent
10049	of the clone. Passing a @c null reference indicates that the clone will
10050	be a base image, i.e. completely independent. It is possible to specify
10051	an arbitrary medium for this parameter, including the parent of the

10745
10746	There are two modes of working with the video buffer of the virtual
10747	machine. The <i>indirect</i> mode implies that the IFramebuffer
10748	implementation allocates a memory buffer for the requested display mode
10749	and provides it to the virtual machine. In <i>direct</i> mode, the
10750	IFramebuffer implementation uses the memory buffer allocated and owned
10751	by the virtual machine. This buffer represents the video memory of the
10752	emulated video adapter (so called <i>guest VRAM</i>). The direct mode is
10753	usually faster because the implementation gets a raw pointer to the
10754	guest VRAM buffer which it can directly use for visualizing the contents
10755	of the virtual display, as opposed to the indirect mode where the
10756	contents of guest VRAM are copied to the memory buffer provided by
10757	the implementation every time a display update occurs.
10758
10759	It is important to note that the direct mode is really fast only when
10760	the implementation uses the given guest VRAM buffer directly, for
10761	example, by blitting it to the window representing the virtual machine's
10762	display, which saves at least one copy operation comparing to the
10763	indirect mode. However, using the guest VRAM buffer directly is not
10764	always possible: the format and the color depth of this buffer may be
10765	not supported by the target window, or it may be unknown (opaque) as in
10766	case of text or non-linear multi-plane VGA video modes. In this case,
10767	the indirect mode (that is always available) should be used as a
10768	fallback: when the guest VRAM contents are copied to the
10769	implementation-provided memory buffer, color and format conversion is
10770	done automatically by the underlying code.
10771
10772	The @a pixelFormat parameter defines whether the direct mode is
10773	available or not. If @a pixelFormat is <link
10774	to="FramebufferPixelFormat_Opaque"/> then direct access to the guest
10775	VRAM buffer is not available -- the @a VRAM, @a bitsPerPixel and
10776	@a bytesPerLine parameters must be ignored and the implementation must use
10777	the indirect mode (where it provides its own buffer in one of the
10778	supported formats). In all other cases, @a pixelFormat together with
10779	@a bitsPerPixel and @a bytesPerLine define the format of the video memory
10780	buffer pointed to by the @a VRAM parameter and the implementation is
10781	free to choose which mode to use. To indicate that this frame buffer uses
10782	the direct mode, the implementation of the <link to="#usesGuestVRAM"/>
10783	attribute must return @c true and <link to="#address"/> must
10784	return exactly the same address that is passed in the @a VRAM parameter
10785	of this method; otherwise it is assumed that the indirect strategy is
10786	chosen.
10787
10788	The @a width and @a height parameters represent the size of the
10789	requested display mode in both modes. In case of indirect mode, the
10790	provided memory buffer should be big enough to store data of the given
10791	display mode. In case of direct mode, it is guaranteed that the given
10792	@a VRAM buffer contains enough space to represent the display mode of the
10793	given size. Note that this frame buffer's <link to="#width"/> and <link
10794	to="#height"/> attributes must return exactly the same values as
10795	passed to this method after the resize is completed (see below).
10796
10797	The @a finished output parameter determines if the implementation has
10798	finished resizing the frame buffer or not. If, for some reason, the
10799	resize cannot be finished immediately during this call, @a finished
10800	must be set to @c false, and the implementation must call
10801	<link to="IDisplay::resizeCompleted"/> after it has returned from
10802	this method as soon as possible. If @a finished is @c false, the
10803	machine will not call any frame buffer methods until
10804	<link to="IDisplay::resizeCompleted"/> is called.
10805
10806	Note that if the direct mode is chosen, the <link to="#bitsPerPixel"/>,
10807	<link to="#bytesPerLine"/> and <link to="#pixelFormat"/> attributes of
10808	this frame buffer must return exactly the same values as specified in the
10809	parameters of this method, after the resize is completed. If the
10810	indirect mode is chosen, these attributes must return values describing
10811	the format of the implementation's own memory buffer <link
10812	to="#address"/> points to. Note also that the <link to="#bitsPerPixel"/>
10813	value must always correlate with <link to="#pixelFormat"/>. Note that
10814	the <link to="#pixelFormat"/> attribute must never return <link
10815	to="FramebufferPixelFormat_Opaque"/> regardless of the selected mode.
10816

10818	This method is called by the IDisplay object under the

11441
11442	In host pipe mode, the #path attribute specifies the path to the pipe on

11444	determines if this pipe is created by the virtual machine process at
11445	machine startup or it must already exist before starting machine
11446	execution.
11447
11448	In host device mode, the #path attribute specifies the name of the
11449	serial port device on the host computer.
11450
11451	There is also a third communication mode: the disconnected mode. In this
11452	mode, the guest OS running inside the virtual machine will be able to
11453	detect the serial port, but all port write operations will be discarded

11942	<desc>
11943	The IUSBDeviceFilter interface represents an USB device filter used
11944	to perform actions on a group of USB devices.
11945
11946	This type of filters is used by running virtual machines to
11947	automatically capture selected USB devices once they are physically
11948	attached to the host computer.
11949
11950	A USB device is matched to the given device filter if and only if all
11951	attributes of the device match the corresponding attributes of the
11952	filter (that is, attributes are joined together using the logical AND
11953	operation). On the other hand, all together, filters in the list of
11954	filters carry the semantics of the logical OR operation. So if it is
11955	desirable to create a match like "this vendor id OR this product id",
11956	one needs to create two filters and specify "any match" (see below)
11957	for unused attributes.
11958
11959	All filter attributes used for matching are strings. Each string
11960	is an expression representing a set of values of the corresponding
11961	device attribute, that will match the given filter. Currently, the
11962	following filtering expressions are supported:
11963
11964	<ul>
11965	<li><i>Interval filters</i>. Used to specify valid intervals for
11966	integer device attributes (Vendor ID, Product ID and Revision).
11967	The format of the string is:
11968
11969	<tt>int:((m)\|([m]-[n]))(,(m)\|([m]-[n]))*</tt>
11970
11971	where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
11972	(starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
11973	or decimal (otherwise) form, so that <tt>m < n</tt>. If <tt>m</tt>
11974	is omitted before a dash (<tt>-</tt>), the minimum possible integer
11975	is assumed; if <tt>n</tt> is omitted after a dash, the maximum
11976	possible integer is assumed.
11977	</li>
11978	<li><i>Boolean filters</i>. Used to specify acceptable values for
11979	boolean device attributes. The format of the string is:
11980
11981	<tt>true\|false\|yes\|no\|0\|1</tt>
11982
11983	</li>
11984	<li><i>Exact match</i>. Used to specify a single value for the given
11985	device attribute. Any string that doesn't start with <tt>int:</tt>
11986	represents the exact match. String device attributes are compared to
11987	this string including case of symbols. Integer attributes are first
11988	converted to a string (see individual filter attributes) and then
11989	compared ignoring case.
11990
11991	</li>
11992	<li><i>Any match</i>. Any value of the corresponding device attribute
11993	will match the given filter. An empty or @c null string is
11994	used to construct this type of filtering expressions.
11995
11996	</li>
11997	</ul>
11998
11999	<note>
12000	On the Windows host platform, interval filters are not currently
12001	available. Also all string filter attributes
12002	(<link to="#manufacturer"/>, <link to="#product"/>,
12003	<link to="#serialNumber"/>) are ignored, so they behave as
12004	<i>any match</i> no matter what string expression is specified.

12048	Note that for interval filters, it's best to use the hexadecimal

12050	so the expression <tt>int:0x0100-0x0199</tt> will match any

12113	of the USB device physically attached to the host computer regarding
12114	its state on the host computer and availability to guest computers
12115	(all currently running virtual machines).
12116
12117	Once a supported USB device is attached to the host, global USB
12118	filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
12119	either ignore the device, or put it to USBDeviceState_Held state, or do
12120	nothing. Unless the device is ignored by global filters, filters of all
12121	currently running guests (<link to="IUSBController::deviceFilters"/>) are
12122	activated that can put it to USBDeviceState_Captured state.
12123
12124	If the device was ignored by global filters, or didn't match
12125	any filters at all (including guest ones), it is handled by the host
12126	in a normal way. In this case, the device state is determined by
12127	the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
12128	or USBDeviceState_Available, depending on the current device usage.
12129
12130	Besides auto-capturing based on filters, the device can be manually
12131	captured by guests (<link to="IConsole::attachUSBDevice"/>) if its
12132	state is USBDeviceState_Busy, USBDeviceState_Available or
12133	USBDeviceState_Held.
12134
12135	<note>
12136	Due to differences in USB stack implementations in Linux and Win32,
12137	states USBDeviceState_Busy and USBDeviceState_vailable are applicable
12138	only to the Linux version of the product. This also means that (<link
12139	to="IConsole::attachUSBDevice"/>) can only succeed on Win32 if the
12140	device state is USBDeviceState_Held.

12424	<interface
12425	name="ISharedFolder" extends="$unknown"

12428	>
12429	<desc>
12430	The ISharedFolder interface represents a folder in the host computer's
12431	file system accessible from the guest OS running inside a virtual
12432	machine using an associated logical name.
12433
12434	There are three types of shared folders:
12435	<ul>
12436	<li><i>Global</i> (<link to="IVirtualBox::sharedFolders"/>), shared
12437	folders available to all virtual machines.</li>
12438	<li><i>Permanent</i> (<link to="IMachine::sharedFolders"/>),
12439	VM-specific shared folders available to the given virtual machine at
12440	startup.</li>
12441	<li><i>Transient</i> (<link to="IConsole::sharedFolders"/>),
12442	VM-specific shared folders created in the session context (for
12443	example, when the virtual machine is running) and automatically
12444	discarded when the session is closed (the VM is powered off).</li>
12445	</ul>
12446
12447	Logical names of shared folders must be unique within the given scope
12448	(global, permanent or transient). However, they do not need to be unique
12449	across scopes. In this case, the definition of the shared folder in a
12450	more specific scope takes precedence over definitions in all other
12451	scopes. The order of precedence is (more specific to more general):
12452	<ol>
12453	<li>Transient definitions</li>
12454	<li>Permanent definitions</li>
12455	<li>Global definitions</li>
12456	</ol>
12457
12458	For example, if MyMachine has a shared folder named
12459	<tt>C_DRIVE</tt> (that points to <tt>C:\\</tt>), then creating a
12460	transient shared folder named <tt>C_DRIVE</tt> (that points
12461	to <tt>C:\\\\WINDOWS</tt>) will change the definition
12462	of <tt>C_DRIVE</tt> in the guest OS so
12463	that <tt>\\\\VBOXSVR\\C_DRIVE</tt> will give access
12464	to <tt>C:\\WINDOWS</tt> instead of <tt>C:\\</tt> on the host
12465	PC. Removing the transient shared folder <tt>C_DRIVE</tt> will restore
12466	the previous (permanent) definition of <tt>C_DRIVE</tt> that points
12467	to <tt>C:\\</tt> if it still exists.
12468
12469	Note that permanent and transient shared folders of different machines
12470	are in different name spaces, so they don't overlap and don't need to
12471	have unique logical names.
12472
12473	<note>
12474	Global shared folders are not implemented in the current version of the
12475	product.

12880	<desc>
12881	The ISession interface represents a serialization primitive for virtual
12882	machines.
12883
12884	With VirtualBox, every time one wishes to manipulate a virtual machine
12885	(e.g. change its settings or start execution), a session object is
12886	required. Such an object must be passed to one of the session methods
12887	that open the given session, which then initiates the machine manipulation.
12888
12889	A session serves several purposes: it identifies to the inter-process VirtualBox
12890	code which process is currently working with the virtual machine, and it ensures
12891	that there are no incompatible requests from several processes for the
12892	same virtual machine. Session objects can therefore be thought of as mutex
12893	semaphores that lock virtual machines to prevent conflicting accesses from
12894	several processes.
12895
12896	How sessions objects are used depends on whether you use the Main API
12897	via COM or via the webservice:
12898
12899	<ul>
12900	<li>When using the COM API directly, an object of the Session class from the
12901	VirtualBox type library needs to be created. In regular COM C++ client code,
12902	this can be done by calling <tt>createLocalObject()</tt>, a standard COM API.
12903	This object will then act as a local session object in further calls to open
12904	a session.
12905	</li>
12906
12907	<li>In the webservice, the session manager (IWebsessionManager) instead creates
12908	one session object automatically when <link to="IWebsessionManager::logon" />
12909	is called. A managed object reference to that session object can be retrieved by
12910	calling <link to="IWebsessionManager::getSessionObject" />. This session object
12911	reference can then be used to open sessions.
12912	</li>
12913	</ul>
12914
12915	Sessions are mainly used in two variations:
12916
12917	<ul>
12918	<li>
12919	To start a virtual machine in a separate process, one would call
12920	<link to="IVirtualBox::openRemoteSession"/>, which requires a session
12921	object as its first parameter. This session then identifies the caller
12922	and lets him control the started machine (for example, pause machine
12923	execution or power it down) as well as be notified about machine
12924	execution state changes.
12925	</li>
12926
12927	<li>To alter machine settings, or to start machine execution within the
12928	current process, one needs to open a direct session for the machine first by
12929	calling <link to="IVirtualBox::openSession"/>. While a direct session
12930	is open within one process, no any other process may open another direct
12931	session for the same machine. This prevents the machine from being changed
12932	by other processes while it is running or while the machine is being configured.
12933	</li>
12934	</ul>
12935
12936	One also can attach to an existing direct session already opened by
12937	another process (for example, in order to send a control request to the
12938	virtual machine such as the pause or the reset request). This is done by
12939	calling <link to="IVirtualBox::openExistingSession"/>.
12940
12941	<note>
12942	Unless you are trying to write a new VirtualBox front-end that
12943	performs direct machine execution (like the VirtualBox or VBoxSDL
12944	front-ends), don't call <link to="IConsole::powerUp"/> in a direct
12945	session opened by <link to="IVirtualBox::openSession"/> and use this
12946	session only to change virtual machine settings. If you simply want to
12947	start virtual machine execution using one of the existing front-ends
12948	(for example the VirtualBox GUI or headless server), simply use
12949	<link to="IVirtualBox::openRemoteSession"/>; these front-ends
12950	will power up the machine automatically for you.

12978	It is recommended that every time an "open session" method (such as
12979	<link to="IVirtualBox::openRemoteSession" /> or
12980	<link to="IVirtualBox::openSession" />) has been called to
12981	manipulate a virtual machine, the caller invoke
12982	ISession::close() when it's done doing so. Since sessions are
12983	serialization primitives much like ordinary mutexes, they are
12984	best used the same way: for each "open" call, there should be
12985	a matching "close" call, even when errors occur.
12986
12987	Otherwise, if a direct session for a machine opened with
12988	<link to="IVirtualBox::openSession"/> is not explicitly closed
12989	when the application terminates, the state of the machine will
12990	be set to <link to="MachineState_Aborted" /> on the server.
12991
12992	Generally, it is recommended to close all open sessions explicitly
12993	before terminating the application (regardless of the reason for
12994	the termination).
12995
12996	<note>
12997	Do not expect the session state (<link to="ISession::state" />
12998	to return to "Closed" immediately after you invoke
12999	ISession::close(), particularly if you have started a remote
13000	session to execute the VM in a new process. The session state will
13001	automatically return to "Closed" once the VM is no longer executing,
13002	which can of course take a very long time.

13370	The IPerformanceCollector interface represents a service that collects and
13371	stores performance metrics data.
13372
13373	Performance metrics are associated with objects of interfaces like IHost and
13374	IMachine. Each object has a distinct set of performance metrics.
13375	The set can be obtained with <link to="IPerformanceCollector::getMetrics"/>.
13376
13377	Metric data is collected at the specified intervals and is retained
13378	internally. The interval and the number of retained samples can be set
13379	with <link to="IPerformanceCollector::setupMetrics" />.
13380
13381	Metrics are organized hierarchically, with each level separated by a
13382	slash (/) character. Generally, the scheme for metric names is like this:
13383
13384	<tt>Category/Metric[/SubMetric][:aggregation]</tt>
13385
13386	"Category/Metric" together form the base metric name. A base metric is the
13387	smallest unit for which a sampling interval and the number of retained
13388	samples can be set. Only base metrics can be enabled and disabled. All
13389	sub-metrics are collected when their base metric is collected.
13390	Collected values for any set of sub-metrics can be queried with
13391	<link to="IPerformanceCollector::queryMetricsData" />.
13392
13393	For example "CPU/Load/User:avg"
13394	metric name stands for the "CPU" category, "Load" metric, "User" submetric,
13395	"average" aggregate. An aggregate function is computed over all retained
13396	data. Valid aggregate functions are:
13397
13398	<ul>
13399	<li>avg -- average</li>
13400	<li>min -- minimum</li>
13401	<li>max -- maximum</li>
13402	</ul>
13403
13404	When setting up
13405	metric parameters, querying metric data, enabling or disabling metrics
13406	wildcards can be used in metric names to specify a subset of metrics. For
13407	example, to select all CPU-related metrics use <tt>CPU/*</tt>, all
13408	averages can be queried using <tt>*:avg</tt> and so on. To query metric
13409	values without aggregates <tt>*:</tt> can be used.
13410
13411	The valid names for base metrics are:
13412
13413	<ul>
13414	<li>CPU/Load</li>
13415	<li>CPU/MHz</li>
13416	<li>RAM/Usage</li>
13417	</ul>
13418
13419	The general sequence for collecting and retrieving the metrics is:
13420	<ul>
13421	<li>
13422	Obtain an instance of IPerformanceCollector with
13423	<link to="IVirtualBox::performanceCollector" />
13424	</li>
13425	<li>
13426	Allocate and populate an array with references to objects the metrics
13427	will be collected for. Use references to IHost and IMachine objects.
13428	</li>
13429	<li>
13430	Allocate and populate an array with base metric names the data will be
13431	collected for.
13432	</li>
13433	<li>
13434	Call <link to="IPerformanceCollector::setupMetrics" />. From now on the
13435	metric data will be collected and stored.
13436	</li>
13437	<li>
13438	Wait for the data to get collected.
13439	</li>
13440	<li>
13441	Allocate and populate an array with references to objects the metric
13442	values will be queried for. You can re-use the object array used for
13443	setting base metrics.
13444	</li>
13445	<li>
13446	Allocate and populate an array with metric names the data will be
13447	collected for. Note that metric names differ from base metric names.
13448	</li>
13449	<li>
13450	Call <link to="IPerformanceCollector::queryMetricsData" />. The data that
13451	have been collected so far are returned. Note that the values are still
13452	retained internally and data collection continues.
13453	</li>
13454	</ul>
