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

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

495	Virtual machine execution state.
496
497	This enumeration represents possible values of the <link
498	to="IMachine::state"/> attribute.
499
500	Below is the basic virtual machine state diagram. It shows how the state
501	changes during virtual machine execution. The text in square braces shows
502	a method of the IConsole interface that performs the given state
503	transition.
504

511	\| \| ^ \| ^ \|

517	\| \| \| \|
518	\| +-------- Saving <--------[saveState()]<----------+---------------------+
519	\| \| \|
520	+-------------- Stopping -------[powerDown()]<----------+---------------------+
521	</pre>
522
523	Note that states to the right from PoweredOff, Aborted and Saved in the
524	above diagram are called <i>online VM states</i>. These states
525	represent the virtual machine which is being executed in a dedicated
526	process (usually with a GUI window attached to it where you can see the
527	activity of the virtual machine and interact with it). There are two
528	special pseudo-states, FirstOnline and LastOnline, that can be used in
529	relational expressions to detect if the given machine state is online or
530	not:
531
532	<pre>
533	if (machine.GetState() >= MachineState_FirstOnline &&
534	machine.GetState() <= MachineState_LastOnline)
535	{
536	...the machine is being executed...
537	}
538	</pre>
539
540	When the virtual machine is in one of the online VM states (that is, being
541	executed), only a few machine settings can be modified. Methods working
542	with such settings contain an explicit note about that. An attempt to
543	change any oter setting or perform a modifying operation during this time
544	will result in the <link to="VBOX_E_INVALID_VM_STATE"/> error.
545
546	All online states except Running, Paused and Stuck are transitional: they
547	represent temporary conditions of the virtual machine that will last as
548	long as the operation that initiated such a condition.
549
550	The Stuck state is a special case. It means that execution of the machine
551	has reached the "Guru Meditation" condition. This condition indicates an
552	internal VMM (virtual machine manager) failure which may happen as a
553	result of either an unhandled low-level virtual hardware exception or one
554	of the recompiler exceptions (such as the <i>too-many-traps</i>
555	condition).
556
557	Note also that any online VM state may transit to the Aborted state. This
558	happens if the process that is executing the virtual machine terminates
559	unexpectedly (for example, crashes). Other than that, the Aborted state is
560	equivalent to PoweredOff.
561
562	There are also a few additional state diagrams that do not deal with
563	virtual machine execution and therefore are shown separately. The states
564	shown on these diagrams are called <i>offline VM states</i> (this includes
565	PoweredOff, Aborted and Saved too).
566
567	The first diagram shows what happens when a lengthy setup operation is
568	being executed (such as <link to="IMachine::attachDevice"/>).
569
570	<pre>
571	+----------------------------------(same state as before the call)------+
572	\| \|
573	+-> PoweredOff --+ \|
574	\| \| \|
575	\|-> Aborted -----+-->[lengthy VM configuration call] --> SettingUp -----+
576	\| \|
577	+-> Saved -------+
578	</pre>
579
580	The next two diagrams demonstrate the process of taking a snapshot of a
581	powered off virtual machine, restoring the state to that as of a snapshot
582	or deleting a snapshot, respectively.
583
584	<pre>
585	+----------------------------------(same state as before the call)------+
586	\| \|
587	+-> PoweredOff --+ \|
588	\| +-->[takeSnapshot()] -------------------> Saving ------+
589	+-> Aborted -----+
590
591	+-> PoweredOff --+
592	\| \|
593	\| Aborted -----+-->[restoreSnapshot() ]-------> RestoringSnapshot -+
594	\| \| [deleteSnapshot() ]-------> DeletingSnapshot --+
595	+-> Saved -------+ \|
596	\| \|
597	+---(Saved if restored from an online snapshot, PoweredOff otherwise)---+
598	</pre>
599
600	Note that the Saving state is present in both the offline state group and
601	online state group. Currently, the only way to determine what group is
602	assumed in a particular case is to remember the previous machine state: if
603	it was Running or Paused, then Saving is an online state, otherwise it is
604	an offline state. This inconsistency may be removed in one of the future
605	versions of VirtualBox by adding a new state.
606
607	<note internal="yes">
608	For whoever decides to touch this enum: In order to keep the
609	comparisons involving FirstOnline and LastOnline pseudo-states valid,
610	the numeric values of these states must be correspondingly updated if
611	needed: for any online VM state, the condition
612	<tt>FirstOnline <= state <= LastOnline</tt> must be
613	@c true. The same relates to transient states for which
614	the condition <tt>FirstOnline <= state <= LastOnline</tt> must be
615	@c true.

1162	>
1163	<desc>
1164	The IVirtualBoxErrorInfo interface represents extended error information.
1165
1166	Extended error information can be set by VirtualBox components after
1167	unsuccessful or partially successful method invocation. This information
1168	can be retrieved by the calling party as an IVirtualBoxErrorInfo object
1169	and then shown to the client in addition to the plain 32-bit result code.
1170
1171	In MS COM, this interface extends the IErrorInfo interface,
1172	in XPCOM, it extends the nsIException interface. In both cases,
1173	it provides a set of common attributes to retrieve error
1174	information.
1175
1176	Sometimes invocation of some component's method may involve methods of
1177	other components that may also fail (independently of this method's
1178	failure), or a series of non-fatal errors may precede a fatal error that
1179	causes method failure. In cases like that, it may be desirable to preserve
1180	information about all errors happened during method invocation and deliver
1181	it to the caller. The <link to="#next"/> attribute is intended
1182	specifically for this purpose and allows to represent a chain of errors
1183	through a single IVirtualBoxErrorInfo object set after method invocation.
1184
1185	Note that errors are stored to a chain in the reverse order, i.e. the
1186	initial error object you query right after method invocation is the last
1187	error set by the callee, the object it points to in the @a next attribute
1188	is the previous error and so on, up to the first error (which is the last
1189	in the chain).

1197	always. For example, on Win32, CoCreateInstance() will most
1198	likely return E_NOINTERFACE upon unsuccessful component
1199	instantiation attempt, but not the value the component factory
1200	returned. Value is typed 'long', not 'result',
1201	to make interface usable from scripting languages.

1518
1519	<ol>
1520	<li>
1521	Call this method to have a new machine created. The returned machine
1522	object will be "mutable" allowing to change any machine property.

1524
1525	<li>
1526	Configure the machine using the appropriate attributes and methods.
1527	</li>
1528
1529	<li>
1530	Call <link to="IMachine::saveSettings" /> to write the settings
1531	to the machine's XML settings file. The configuration of the newly
1532	created machine will not be saved to disk until this method is
1533	called.
1534	</li>
1535
1536	<li>
1537	Call <link to="#registerMachine" /> to add the machine to the list
1538	of machines known to VirtualBox.
1539	</li>
1540	</ol>
1541
1542	You should specify valid name for the newly created machine when calling
1543	this method. See the <link to="IMachine::name"/> attribute description
1544	for more details about the machine name.
1545
1546	The specified guest OS type identifier must match an ID of one of known
1547	guest OS types listed in the <link to="IVirtualBox::guestOSTypes"/>
1548	array.
1549
1550	Every machine has a <i>settings file</i> that is used to store
1551	the machine configuration. This file is stored in a directory called the
1552	<i>machine settings subfolder</i>. Both the settings subfolder and file
1553	will have a name that corresponds to the name of the virtual machine.
1554	You can specify where to create the machine setting subfolder using the
1555	@a baseFolder argument. The base folder can be absolute (full path) or

1769	<desc>
1770	Opens a medium from an existing storage location.
1771
1772	Once a medium has been opened, it can be passed to other VirtualBox
1773	methods, in particular to <link to="IMachine::attachDevice" />.
1774
1775	Depending on the given device type, the file at the storage location
1776	must be in one of the media formats understood by VirtualBox:
1777
1778	<ul>
1779	<li>With a "HardDisk" device type, the file must be a hard disk image
1780	in one of the formats supported by VirtualBox (see
1781	<link to="ISystemProperties::mediumFormats" />).
1782	After this method succeeds, if the medium is a base medium, it
1783	will be added to the <link to="#hardDisks"/> array attribute. </li>
1784	<li>With a "DVD" device type, the file must be an ISO 9960 CD/DVD image.
1785	After this method succeeds, the medium will be added to the
1786	<link to="#DVDImages"/> array attribute.</li>
1787	<li>With a "Floppy" device type, the file must be an RAW floppy image.
1788	After this method succeeds, the medium will be added to the
1789	<link to="#floppyImages"/> array attribute.</li>
1790	</ul>
1791
1792	After having been opened, the medium can be found by the <link to="#findMedium"/>
1793	method and can be attached to virtual machines. See <link to="IMedium" /> for more details.
1794
1795	The UUID of the newly opened medium will either be retrieved from the
1796	storage location, if the format supports it (e.g. for hard disk images),
1797	or a new UUID will be randomly generated (e.g. for ISO and RAW files).
1798	If for some reason you need to change the medium's UUID, use
1799	<link to="IMedium::setIDs" />.
1800
1801	If a differencing hard disk medium is to be opened by this method, the
1802	operation will succeed only if its parent medium and all ancestors,
1803	if any, are already known to this VirtualBox installation (for example,
1804	were opened by this method before).
1805
1806	This method attempts to guess the storage format of the specified medium
1807	by reading medium data at the specified location.
1808
1809	If @a accessMode is ReadWrite (which it should be for hard disks and floppies),
1810	the image is opened for read/write access and must have according permissions,
1811	as VirtualBox may actually write status information into the disk's metadata
1812	sections.
1813
1814	Note that write access is required for all typical hard disk usage in VirtualBox,
1815	since VirtualBox may need to write metadata such as a UUID into the image.
1816	The only exception is opening a source image temporarily for copying and
1817	cloning (see <link to="IMedium::cloneTo" /> when the image will be closed
1818	again soon.
1819
1820	The format of the location string is storage format specific. See
1821	<link to="IMedium::location"/>, IMedium and
1822	<link to="ISystemProperties::defaultHardDiskFolder"/> for more details.
1823
1824	Prior to VirtualBox 3.3, opening a medium added it to a global media
1825	registry in the VirtualBox.xml file, which was shared between
1826	all machines and made transporting machines and their media from one
1827	host to another difficult.
1828
1829	Starting with VirtualBox 3.3, media are only added to a registry when
1830	they are attached to a machine. Machines created with VirtualBox 3.3
1831	or later can have their own media registry. As a result, a medium attached
1832	to such a machine will be remembered in that machine's XML settings file.
1833	Media attached to older machines will continue to be added to the global
1834	registry.

2062
2063	where @c name is the property name and @c group, @c subgroup are zero
2064	or more property group specifiers. Each element (group or name) in
2065	the property mask may be either a Latin string or an asterisk symbol
2066	(@c "*") which is used to match any string for the given element. A
2067	property mask that doesn't contain asterisk symbols represents a
2068	single fully qualified property name.
2069
2070	Groups in the fully qualified property name go from more generic (the
2071	left-most part) to more specific (the right-most part). The first
2072	element is usually a name of the object the property belongs to. The
2073	second element may be either a property name, or a child object name,
2074	or an index if the preceding element names an object which is one of
2075	many objects of the same type. This way, property names form a
2076	hierarchy of properties. Here are some examples of property names:
2077
2078	<table>
2079	<tr>
2080	<td><tt>VirtualBox.version</tt></td>
2081	<td><link to="IVirtualBox::version"/> property</td>
2082	</tr>
2083	<tr>
2084	<td><tt>Machine.<UUID>.name</tt></td>
2085	<td><link to="IMachine::name"/> property of the machine with the
2086	given UUID</td>
2087	</tr>
2088	</table>
2089
2090	Most property names directly correspond to the properties of objects
2091	(components) provided by the VirtualBox library and may be used to
2092	track changes to these properties. However, there may be
2093	pseudo-property names that don't correspond to any existing object's
2094	property directly, as well as there may be object properties that
2095	don't have a corresponding property name that is understood by this
2096	method, and therefore changes to such properties cannot be
2097	tracked. See individual object's property descriptions to get a
2098	fully qualified property name that can be used with this method (if
2099	any).
2100
2101	There is a special property mask @c "*" (i.e. a string consisting of a
2102	single asterisk symbol) that can be used to match all properties.
2103	Below are more examples of property masks:
2104
2105	<table>
2106	<tr>
2107	<td><tt>VirtualBox.*</tt></td>
2108	<td>Track all properties of the VirtualBox object</td>
2109	</tr>
2110	<tr>
2111	<td><tt>Machine.*.name</tt></td>
2112	<td>Track changes to the <link to="IMachine::name"/> property of
2113	all registered virtual machines</td>
2114	</tr>

2391	Represents a platform-independent appliance in OVF format. An instance of this is returned
2392	by <link to="IVirtualBox::createAppliance" />, which can then be used to import and export
2393	virtual machines within an appliance with VirtualBox.
2394
2395	The OVF standard suggests two different physical file formats:
2396
2397	<ol>
2398	<li>If the appliance is distributed as a set of files, there must be at least one XML descriptor
2399	file that conforms to the OVF standard and carries an <tt>.ovf</tt> file extension. If
2400	this descriptor file references other files such as disk images, as OVF appliances typically
2401	do, those additional files must be in the same directory as the descriptor file.</li>
2402
2403	<li>If the appliance is distributed as a single file, it must be in TAR format and have the
2404	<tt>.ova</tt> file extension. This TAR file must then contain at least the OVF descriptor
2405	files and optionally other files.
2406
2407	At this time, VirtualBox does not not yet support the packed (TAR) variant; support will
2408	be added with a later version.</li>
2409	</ol>
2410
2411	<b>Importing</b> an OVF appliance into VirtualBox as instances of
2412	<link to="IMachine" /> involves the following sequence of API calls:
2413
2414	<ol>
2415	<li>Call <link to="IVirtualBox::createAppliance" />. This will create an empty IAppliance object.
2416	</li>
2417
2418	<li>On the new object, call <link to="#read" /> with the full path of the OVF file you
2419	would like to import. So long as this file is syntactically valid, this will succeed
2420	and fill the appliance object with the parsed data from the OVF file.
2421	</li>
2422
2423	<li>Next, call <link to="#interpret" />, which analyzes the OVF data and sets up the
2424	contents of the IAppliance attributes accordingly. These can be inspected by a
2425	VirtualBox front-end such as the GUI, and the suggestions can be displayed to the
2426	user. In particular, the <link to="#virtualSystemDescriptions" /> array contains
2427	instances of <link to="IVirtualSystemDescription" /> which represent the virtual
2428	systems (machines) in the OVF, which in turn describe the virtual hardware prescribed
2429	by the OVF (network and hardware adapters, virtual disk images, memory size and so on).
2430	The GUI can then give the user the option to confirm and/or change these suggestions.
2431	</li>
2432
2433	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
2434	virtual system (machine) to override the suggestions made by the interpret() routine.
2435	</li>
2436
2437	<li>Finally, call <link to="#importMachines" /> to create virtual machines in
2438	VirtualBox as instances of <link to="IMachine" /> that match the information in the
2439	virtual system descriptions. After this call suceeded, the UUIDs of the machines created
2440	can be found in the <link to="#machines" /> array attribute.
2441	</li>
2442	</ol>
2443
2444	<b>Exporting</b> VirtualBox machines into an OVF appliance involves the following steps:
2445
2446	<ol>
2447	<li>As with importing, first call <link to="IVirtualBox::createAppliance" /> to create
2448	an empty IAppliance object.
2449	</li>
2450
2451	<li>For each machine you would like to export, call <link to="IMachine::export" />
2452	with the IAppliance object you just created. Each such call creates one instance of
2453	<link to="IVirtualSystemDescription" /> inside the appliance.
2454	</li>
2455
2456	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
2457	virtual system (machine) to override the suggestions made by the export() routine.
2458	</li>
2459
2460	<li>Finally, call <link to="#write" /> with a path specification to have the OVF
2461	file written.</li>
2462	</ol>
2463
2464	</desc>
2465
2466	<attribute name="path" type="wstring" readonly="yes">
2467	<desc>Path to the main file of the OVF appliance, which is either the <tt>.ovf</tt> or

2703	<method name="getDescription">
2704	<desc>Returns information about the virtual system as arrays of instruction items. In each array, the
2705	items with the same indices correspond and jointly represent an import instruction for VirtualBox.
2706
2707	The list below identifies the value sets that are possible depending on the
2708	<link to="VirtualSystemDescriptionType" /> enum value in the array item in @a aTypes[]. In each case,
2709	the array item with the same index in @a aOvfValues[] will contain the original value as contained
2710	in the OVF file (just for informational purposes), and the corresponding item in @a aVBoxValues[]
2711	will contain a suggested value to be used for VirtualBox. Depending on the description type,
2712	the @a aExtraConfigValues[] array item may also be used.
2713
2714	<ul>
2715	<li>
2716	"OS": the guest operating system type. There must be exactly one such array item on import. The
2717	corresponding item in @a aVBoxValues[] contains the suggested guest operating system for VirtualBox.
2718	This will be one of the values listed in <link to="IVirtualBox::guestOSTypes" />. The corresponding
2719	item in @a aOvfValues[] will contain a numerical value that described the operating system in the OVF.
2720	</li>
2721	<li>
2722	"Name": the name to give to the new virtual machine. There can be at most one such array item;
2723	if none is present on import, then an automatic name will be created from the operating system
2724	type. The correponding item im @a aOvfValues[] will contain the suggested virtual machine name
2725	from the OVF file, and @a aVBoxValues[] will contain a suggestion for a unique VirtualBox
2726	<link to="IMachine" /> name that does not exist yet.
2727	</li>
2728	<li>
2729	"Description": an arbitrary description.
2730	</li>
2731	<li>
2732	"License": the EULA section from the OVF, if present. It is the responsibility of the calling
2733	code to display such a license for agreement; the Main API does not enforce any such policy.
2734	</li>
2735	<li>
2736	Miscellaneous: reserved for future use.
2737	</li>
2738	<li>
2739	"CPU": the number of CPUs. There can be at most one such item, which will presently be ignored.
2740	</li>
2741	<li>
2742	"Memory": the amount of guest RAM, in bytes. There can be at most one such array item; if none
2743	is present on import, then VirtualBox will set a meaningful default based on the operating system
2744	type.
2745	</li>
2746	<li>
2747	"HardDiskControllerIDE": an IDE hard disk controller. There can be at most two such items.
2748	An optional value in @a aOvfValues[] and @a aVBoxValues[] can be "PIIX3" or "PIIX4" to specify
2749	the type of IDE controller; this corresponds to the ResourceSubType element which VirtualBox
2750	writes into the OVF.
2751	The matching item in the @a aRefs[] array will contain an integer that items of the "Harddisk"
2752	type can use to specify which hard disk controller a virtual disk should be connected to.
2753	Note that in OVF, an IDE controller has two channels, corresponding to "master" and "slave"
2754	in traditional terminology, whereas the IDE storage controller that VirtualBox supports in
2755	its virtual machines supports four channels (primary master, primary slave, secondary master,
2756	secondary slave) and thus maps to two IDE controllers in the OVF sense.
2757	</li>
2758	<li>
2759	"HardDiskControllerSATA": an SATA hard disk controller. There can be at most one such item. This
2760	has no value in @a aOvfValues[] or @a aVBoxValues[].
2761	The matching item in the @a aRefs[] array will be used as with IDE controllers (see above).
2762	</li>
2763	<li>
2764	"HardDiskControllerSCSI": a SCSI hard disk controller. There can be at most one such item.
2765	The items in @a aOvfValues[] and @a aVBoxValues[] will either be "LsiLogic", "BusLogic" or
2766	"LsiLogicSas". (Note that in OVF, the LsiLogicSas controller is treated as a SCSI controller
2767	whereas VirtualBox considers it a class of storage controllers of its own; see
2768	<link to="StorageControllerType" />).
2769	The matching item in the @a aRefs[] array will be used as with IDE controllers (see above).
2770	</li>
2771	<li>
2772	"HardDiskImage": a virtual hard disk, most probably as a reference to an image file. There can be an
2773	arbitrary number of these items, one for each virtual disk image that accompanies the OVF.
2774
2775	The array item in @a aOvfValues[] will contain the file specification from the OVF file (without
2776	a path since the image file should be in the same location as the OVF file itself), whereas the
2777	item in @a aVBoxValues[] will contain a qualified path specification to where VirtualBox uses the
2778	hard disk image. This means that on import the image will be copied and converted from the
2779	"ovf" location to the "vbox" location; on export, this will be handled the other way round.
2780
2781	The matching item in the @a aExtraConfigValues[] array must contain a string of the following
2782	format: "controller=<index>;channel=<c>"
2783	In this string, <index> must be an integer specifying the hard disk controller to connect
2784	the image to. That number must be the index of an array item with one of the hard disk controller
2785	types (HardDiskControllerSCSI, HardDiskControllerSATA, HardDiskControllerIDE).
2786	In addition, <c> must specify the channel to use on that controller. For IDE controllers,
2787	this can be 0 or 1 for master or slave, respectively. For compatibility with VirtualBox versions
2788	before 3.2, the values 2 and 3 (for secondary master and secondary slave) are also supported, but
2789	no longer exported. For SATA and SCSI controllers, the channel can range from 0-29.
2790	</li>
2791	<li>
2792	"CDROM": a virtual CD-ROM drive. The matching item in @a aExtraConfigValue[] contains the same
2793	attachment information as with "HardDiskImage" items.
2794	</li>
2795	<li>
2796	"CDROM": a virtual floppy drive. The matching item in @a aExtraConfigValue[] contains the same
2797	attachment information as with "HardDiskImage" items.
2798	</li>
2799	<li>
2800	"NetworkAdapter": a network adapter. The array item in @a aVBoxValues[] will specify the hardware
2801	for the network adapter, whereas the array item in @a aExtraConfigValues[] will have a string
2802	of the "type=<X>" format, where <X> must be either "NAT" or "Bridged".
2803	</li>
2804	<li>
2805	"USBController": a USB controller. There can be at most one such item. If and only if such an
2806	item ispresent, USB support will be enabled for the new virtual machine.
2807	</li>
2808	<li>
2809	"SoundCard": a sound card. There can be at most one such item. If and only if such an item is
2810	present, sound support will be enabled for the new virtual machine. Note that the virtual
2811	machine in VirtualBox will always be presented with the standard VirtualBox soundcard, which
2812	may be different from the virtual soundcard expected by the appliance.

3426	<desc>
3427	The IMachine interface represents a virtual machine, or guest, created
3428	in VirtualBox.
3429
3430	This interface is used in two contexts. First of all, a collection of
3431	objects implementing this interface is stored in the
3432	<link to="IVirtualBox::machines"/> attribute which lists all the virtual
3433	machines that are currently registered with this VirtualBox
3434	installation. Also, once a session has been opened for the given virtual
3435	machine (e.g. the virtual machine is running), the machine object
3436	associated with the open session can be queried from the session object;
3437	see <link to="ISession"/> for details.
3438
3439	The main role of this interface is to expose the settings of the virtual
3440	machine and provide methods to change various aspects of the virtual
3441	machine's configuration. For machine objects stored in the
3442	<link to="IVirtualBox::machines"/> collection, all attributes are
3443	read-only unless explicitly stated otherwise in individual attribute
3444	and method descriptions.
3445
3446	In order to change a machine setting, a session for this machine must be
3447	opened using one of the <link to="IMachine::lockMachine" /> or
3448	<link to="IMachine::launchVMProcess"/> methods. After the
3449	machine has been successfully locked for a session, a mutable machine object
3450	needs to be queried from the session object and then the desired settings
3451	changes can be applied to the returned object using IMachine attributes and
3452	methods. See the <link to="ISession"/> interface description for more
3453	information about sessions.
3454
3455	Note that IMachine does not provide methods to control virtual machine
3456	execution (such as start the machine, or power it down) -- these methods
3457	are grouped in a separate interface called <link to="IConsole" />.

3464	</attribute>
3465
3466	<attribute name="accessible" type="boolean" readonly="yes">
3467	<desc>
3468	Whether this virtual machine is currently accessible or not.
3469
3470	A machine is always deemed accessible unless it is registered <i>and</i>
3471	its settings file cannot be read or parsed (either because the file itself
3472	is unavailable or has invalid XML contents).
3473
3474	Every time this property is read, the accessibility state of
3475	this machine is re-evaluated. If the returned value is @c false,
3476	the <link to="#accessError"/> property may be used to get the
3477	detailed error information describing the reason of
3478	inaccessibility, including XML error messages.
3479
3480	When the machine is inaccessible, only the following properties
3481	can be used on it:
3482	<ul>
3483	<li><link to="#parent"/></li>
3484	<li><link to="#id"/></li>
3485	<li><link to="#settingsFilePath"/></li>
3486	<li><link to="#accessible"/></li>
3487	<li><link to="#accessError"/></li>
3488	</ul>
3489
3490	An attempt to access any other property or method will return
3491	an error.
3492
3493	The only possible action you can perform on an inaccessible
3494	machine is to unregister it using the
3495	<link to="IMachine::unregister"/> call (or, to check
3496	for the accessibility state once more by querying this
3497	property).
3498
3499	<note>
3500	In the current implementation, once this property returns
3501	@c true, the machine will never become inaccessible
3502	later, even if its settings file cannot be successfully
3503	read/written any more (at least, until the VirtualBox
3504	server is restarted). This limitation may be removed in
3505	future releases.

3514
3515	Reading this property is only valid after the last call to
3516	<link to="#accessible"/> returned @c false (i.e. the
3517	machine is currently unaccessible). Otherwise, a @c null
3518	IVirtualBoxErrorInfo object will be returned.

3524	Name of the virtual machine.
3525
3526	Besides being used for human-readable identification purposes
3527	everywhere in VirtualBox, the virtual machine name is also used
3528	as a name of the machine's settings file and as a name of the
3529	subdirectory this settings file resides in. Thus, every time you
3530	change the value of this property, the settings file will be
3531	renamed once you call <link to="#saveSettings"/> to confirm the
3532	change. The containing subdirectory will be also renamed, but
3533	only if it has exactly the same name as the settings file
3534	itself prior to changing this property (for backward compatibility
3535	with previous API releases). The above implies the following
3536	limitations:
3537	<ul>
3538	<li>The machine name cannot be empty.</li>
3539	<li>The machine name can contain only characters that are valid
3540	file name characters according to the rules of the file
3541	system used to store VirtualBox configuration.</li>
3542	<li>You cannot have two or more machines with the same name
3543	if they use the same subdirectory for storing the machine

4002	<method name="lockMachine">
4003	<desc>
4004	Locks the machine for the given session to enable the caller
4005	to make changes to the machine or start the VM or control
4006	VM execution.
4007
4008	There are two ways to lock a machine for such uses:
4009
4010	<ul>
4011	<li>If you want to make changes to the machine settings,
4012	you must obtain an exclusive write lock on the machine
4013	by setting @a lockType to @c Write.
4014
4015	This will only succeed if no other process has locked
4016	the machine to prevent conflicting changes. Only after
4017	an exclusive write lock has been obtained using this method, one
4018	can change all VM settings or execute the VM in the process
4019	space of the session object. (Note that the latter is only of
4020	interest if you actually want to write a new front-end for
4021	virtual machines; but this API gets called internally by
4022	the existing front-ends such as VBoxHeadless and the VirtualBox
4023	GUI to acquire a write lock on the machine that they are running.)
4024
4025	On success, write-locking the machine for a session creates
4026	a second copy of the IMachine object. It is this second object
4027	upon which changes can be made; in VirtualBox terminology, the
4028	second copy is "mutable". It is only this second, mutable machine
4029	object upon which you can call methods that change the
4030	machine state. After having called this method, you can
4031	obtain this second, mutable machine object using the
4032	<link to="ISession::machine" /> attribute.
4033	</li>
4034	<li>If you only want to check the machine state or control
4035	machine execution without actually changing machine
4036	settings (e.g. to get access to VM statistics or take
4037	a snapshot or save the machine state), then set the
4038	@a lockType argument to @c Shared.
4039
4040	If no other session has obtained a lock, you will obtain an
4041	exclusive write lock as described above. However, if another
4042	session has already obtained such a lock, then a link to that
4043	existing session will be established which allows you
4044	to control that existing session.
4045
4046	To find out which type of lock was obtained, you can
4047	inspect <link to="ISession::type" />, which will have been
4048	set to either @c WriteLock or @c Shared.
4049	</li>
4050	</ul>
4051
4052	In either case, you can get access to the <link to="IConsole" />
4053	object which controls VM execution.
4054
4055	Also in all of the above cases, one must always call
4056	<link to="ISession::unlockMachine" /> to release the lock on the machine, or
4057	the machine's state will eventually be set to "Aborted".
4058
4059	To change settings on a machine, the following sequence is typically
4060	performed:
4061
4062	<ol>
4063	<li>Call this method to obtain an exclusive write lock for the current session.</li>
4064
4065	<li>Obtain a mutable IMachine object from <link to="ISession::machine" />.</li>
4066
4067	<li>Change the settings of the machine by invoking IMachine methods.</li>
4068

4101	<method name="launchVMProcess">
4102	<desc>
4103	Spawns a new process that will execute the virtual machine and obtains a shared
4104	lock on the machine for the calling session.
4105
4106	If launching the VM succeeds, the new VM process will create its own session
4107	and write-lock the machine for it, preventing conflicting changes from other
4108	processes. If the machine is already locked (because it is already running or
4109	because another session has a write lock), launching the VM process will therefore
4110	fail. Reversely, future attempts to obtain a write lock will also fail while the
4111	machine is running.
4112
4113	The caller's session object remains separate from the session opened by the new
4114	VM process. It receives its own <link to="IConsole" /> object which can be used
4115	to control machine execution, but it cannot be used to change all VM settings
4116	which would be available after a <link to="#lockMachine" /> call.
4117
4118	The caller must eventually release the session's shared lock by calling
4119	<link to="ISession::unlockMachine" /> on the local session object once this call
4120	has returned. However, the session's state (see <link to="ISession::state" />)
4121	will not return to "Unlocked" until the remote session has also unlocked
4122	the machine (i.e. the machine has stopped running).
4123
4124	Lauching a VM process can take some time (a new VM is started in a new process,
4125	for which memory and other resources need to be set up). Because of this,
4126	an <link to="IProgress" /> object is returned to allow the caller to wait
4127	for this asynchronous operation to be completed. Until then, the caller's
4128	session object remains in the "Unlocked" state, and its <link to="ISession::machine" />
4129	and <link to="ISession::console" /> attributes cannot be accessed.
4130	It is recommended to use <link to="IProgress::waitForCompletion" /> or
4131	similar calls to wait for completion. Completion is signalled when the VM
4132	is powered on. If launching the VM fails, error messages can be queried
4133	via the progress object, if available.
4134
4135	The progress object will have at least 2 sub-operations. The first
4136	operation covers the period up to the new VM process calls powerUp.
4137	The subsequent operations mirror the <link to="IConsole::powerUp"/>
4138	progress object. Because <link to="IConsole::powerUp"/> may require
4139	some extra sub-operations, the <link to="IProgress::operationCount"/>
4140	may change at the completion of operation.
4141
4142	For details on the teleportation progress operation, see
4143	<link to="IConsole::powerUp"/>.
4144
4145	The @a environment argument is a string containing definitions of
4146	environment variables in the following format:
4147	@code
4148	NAME[=VALUE]\n
4149	NAME[=VALUE]\n
4150	...
4151	@endcode
4152	where <tt>\\n</tt> is the new line character. These environment
4153	variables will be appended to the environment of the VirtualBox server
4154	process. If an environment variable exists both in the server process
4155	and in this list, the value from this list takes precedence over the
4156	server's variable. If the value of the environment variable is
4157	omitted, this variable will be removed from the resulting environment.
4158	If the environment string is @c null or empty, the server environment
4159	is inherited by the started process as is.

4277
4278	This method is intended for managing storage devices in general while a
4279	machine is powered off. It can be used to attach and detach fixed
4280	and removeable media. The following kind of media can be attached
4281	to a machine:
4282
4283	<ul>
4284	<li>For fixed and removable media, you can pass in a medium that was
4285	previously opened using <link to="IVirtualBox::openMedium" />.
4286	</li>
4287
4288	<li>Only for storage devices supporting removable media (such as
4289	DVDs and floppies), you can also specify a null pointer to
4290	indicate an empty drive or one of the medium objects listed
4291	in the <link to="IHost::DVDDrives" /> and <link to="IHost::floppyDrives"/>
4292	arrays to indicate a host drive.
4293	For removeable devices, you can also use <link to="IMachine::mountMedium"/>
4294	to change the media while the machine is running.
4295	</li>
4296	</ul>
4297
4298	In a VM's default configuration of virtual machines, the secondary
4299	master of the IDE controller is used for a CD/DVD drive.
4300
4301	After calling this returns successfully, a new instance of
4302	<link to="IMediumAttachment"/> will appear in the machine's list of medium
4303	attachments (see <link to="IMachine::mediumAttachments"/>).
4304
4305	See <link to="IMedium"/> and <link to="IMediumAttachment"/> for more
4306	information about attaching media.

4315	</note>
4316	<note>
4317	If the medium is being attached indirectly, a new differencing medium
4318	will implicitly be created for it and attached instead. If the

5001
5002	This method does not delete any files. It only changes the machine configuration and
5003	the list of registered machines in the VirtualBox object. To delete the files which
5004	belonged to the machine, including the XML file of the machine itself, call
5005	<link to="#delete"/>, optionally with the array of IMedium objects which was returned
5006	from this method.
5007
5008	How thoroughly this method cleans up the machine configuration before unregistering
5009	the machine depends on the @a cleanupMode argument.
5010
5011	<ul>
5012	<li>With "UnregisterOnly", the machine will only be unregistered, but no additional
5013	cleanup will be performed. The call will fail if the machine is in "Saved" state
5014	or has any snapshots or any media attached (see <link to="IMediumAttachment" />.
5015	It is the responsibility of the caller to delete all such configuration in this mode.
5016	In this mode, the API behaves like the former @c IVirtualBox::unregisterMachine() API
5017	which it replaces.</li>
5018	<li>With "DetachAllReturnNone", the call will succeed even if the machine is in "Saved"
5019	state or if it has snapshots or media attached. All media attached to the current machine
5020	state or in snapshots will be detached. No medium objects will be returned; all of the
5021	machine's media will remain open.</li>
5022	<li>With "DetachAllReturnHardDisksOnly", the call will behave like with "DetachAllReturnNone",
5023	except that all the hard disk medium objects which were detached from the machine will
5024	be returned as an array. This allows for quickly passing them to the <link to="#delete" />
5025	API for closing and deletion.</li>
5026	<li>With "Full", the call will behave like with "DetachAllReturnHardDisksOnly", except
5027	that all media will be returned in the array, including removeable media like DVDs and
5028	floppies. This might be useful if the user wants to inspect in detail which media were
5029	attached to the machine. Be careful when passing the media array to <link to="#delete" />
5030	in that case because users will typically want to preserve ISO and RAW image files.</li>
5031	</ul>
5032
5033	This API does not verify whether the media files returned in the array are still
5034	attached to other machines (i.e. shared between several machines). If such a shared
5035	image is passed to <link to="#delete" /> however, closing the image will fail there
5036	and the image will be silently skipped.
5037
5038	A typical implementation will use "DetachAllReturnHardDisksOnly" and then pass the
5039	resulting IMedia array to <link to="#delete"/>. This way, the machine is completely
5040	deleted with all its saved states and hard disk images, but images for removeable
5041	drives (such as ISO and RAW files) will remain on disk.
5042
5043	The call will fail if the machine is currently locked (see <link to="ISession" />).
5044	It implicitly calls <link to="#saveSettings"/> to save all current machine settings
5045	before unregistering it.
5046
5047	After successful method invocation, the <link to="IMachineRegisteredEvent"/> event
5048	is fired.
5049
5050	<note>
5051	If the given machine is inaccessible (see <link to="#accessible"/>), it
5052	will be unregistered and fully uninitialized right afterwards. As a result,
5053	the returned machine object will be unusable and an attempt to call
5054	<b>any</b> method will return the "Object not ready" error.

5074	storage files are deleted as well. For convenience, this array of media files can be
5075	the same as the one returned from a previous <link to="#unregister" /> call.
5076
5077	This method must only be called on machines which are either write-locked (i.e. on instances
5078	returned by <link to="ISession::machine"/>) or on unregistered machines (i.e. not yet
5079	registered machines created by <link to="IVirtualBox::createMachine"/> or opened by
5080	<link to="IVirtualBox::openMachine"/>, or after having called <link to="#unregister"/>).
5081
5082	The following files will be deleted by this method:
5083	<ul>
5084	<li>If <link to="#unregister" /> had been previously called with a @a cleanupMode
5085	argument other than "UnregisterOnly", this will delete all saved state files that
5086	the machine had in use; possibly one if the machine was in "Saved" state and one
5087	for each online snapshot that the machine had.</li>
5088	<li>On each medium object passed in the @a aMedia array, this will call

6369
6370	The execution state and settings of the associated machine stored in
6371	the snapshot will be deleted. The contents of all differencing media of
6372	this snapshot will be merged with the contents of their dependent child
6373	media to keep the medium chain valid (in other words, all changes
6374	represented by media being deleted will be propagated to their child
6375	medium). After that, this snapshot's differencing medium will be
6376	deleted. The parent of this snapshot will become a new parent for all
6377	its child snapshots.
6378
6379	If the deleted snapshot is the current one, its parent snapshot will
6380	become a new current snapshot. The current machine state is not directly
6381	affected in this case, except that currently attached differencing
6382	media based on media of the deleted snapshot will be also merged as
6383	described above.
6384
6385	If the deleted snapshot is the first or current snapshot, then the
6386	respective IMachine attributes will be adjusted. Deleting the current
6387	snapshot will also implicitly call <link to="IMachine::saveSettings"/>
6388	to make all current machine settings permanent.
6389
6390	Deleting a snapshot has the following preconditions:
6391
6392	<ul>
6393	<li>Child media of all normal media of the deleted snapshot
6394	must be accessible (see <link to="IMedium::state"/>) for this
6395	operation to succeed. In particular, this means that all virtual
6396	machines, whose media are directly or indirectly based on the
6397	media of deleted snapshot, must be powered off.</li>
6398
6399	<li>You cannot delete the snapshot if a medium attached to it has
6400	more than once child medium (differencing images) because otherwise
6401	merging would be impossible. This might be the case if there is
6402	more than one child snapshot or differencing images were created
6403	for other reason (e.g. implicitly because of multiple machine
6404	attachments).</li>
6405	</ul>
6406
6407
6408	The virtual machine's <link to="IMachine::state">state</link> is
6409	changed to "DeletingSnapshot", "DeletingSnapshotOnline" or
6410	"DeletingSnapshotPaused" while this operation is in progress.
6411
6412	<note>
6413	Merging medium contents can be very time and disk space
6414	consuming, if these media are big in size and have many
6415	children. However, if the snapshot being deleted is the last
6416	(head) snapshot on the branch, the operation will be rather
6417	quick.

7284	List of all medium storage formats supported by this VirtualBox
7285	installation.
7286
7287	Keep in mind that the medium format identifier
7288	(<link to="IMediumFormat::id"/>) used in other API calls like
7289	<link to="IVirtualBox::createHardDisk"/> to refer to a particular
7290	medium format is a case-insensitive string. This means that, for
7291	example, all of the following strings:
7292	<pre>
7293	"VDI"
7294	"vdi"
7295	"VdI"</pre>
7296	refer to the same medium format.
7297
7298	Note that the virtual medium framework is backend-based, therefore
7299	the list of supported formats depends on what backends are currently
7300	installed.

7309	<desc>
7310	Identifier of the default medium format used by VirtualBox.
7311
7312	The medium format set by this attribute is used by VirtualBox
7313	when the medium format was not specified explicitly. One example is
7314	<link to="IVirtualBox::createHardDisk"/> with the empty
7315	format argument. A more complex example is implicit creation of
7316	differencing media when taking a snapshot of a virtual machine:
7317	this operation will try to use a format of the parent medium first
7318	and if this format does not support differencing media the default
7319	format specified by this argument will be used.
7320
7321	The list of supported medium formats may be obtained by the
7322	<link to="#mediumFormats"/> call. Note that the default medium
7323	format must have a capability to create differencing media;
7324	otherwise operations that create media implicitly may fail
7325	unexpectedly.

7327	The initial value of this property is <tt>"VDI"</tt> in the current

7395	As opposed to <link to="ISystemProperties::remoteDisplayAuthLibrary" />,

7397	resource (if it is running). Only for this setting (for the webservice),
7398	setting this value to a literal <tt>"null"</tt> string disables authentication,

7400	no matter what user name and password are supplied.
7401
7402	The initial value of this property is <tt>"VRDPAuth"</tt>,

7882	<desc>
7883	The IProgress interface is used to track and control
7884	asynchronous tasks within VirtualBox.
7885
7886	An instance of this is returned every time VirtualBox starts
7887	an asynchronous task (in other words, a separate thread) which
7888	continues to run after a method call returns. For example,
7889	<link to="IConsole::saveState" />, which saves the state of
7890	a running virtual machine, can take a long time to complete.
7891	To be able to display a progress bar, a user interface such as
7892	the VirtualBox graphical user interface can use the IProgress
7893	object returned by that method.
7894
7895	Note that IProgress is a "read-only" interface in the sense
7896	that only the VirtualBox internals behind the Main API can
7897	create and manipulate progress objects, whereas client code
7898	can only use the IProgress object to monitor a task's
7899	progress and, if <link to="#cancelable" /> is @c true,
7900	cancel the task by calling <link to="#cancel" />.
7901
7902	A task represented by IProgress consists of either one or
7903	several sub-operations that run sequentially, one by one (see
7904	<link to="#operation" /> and <link to="#operationCount" />).
7905	Every operation is identified by a number (starting from 0)
7906	and has a separate description.
7907
7908	You can find the individual percentage of completion of the current
7909	operation in <link to="#operationPercent" /> and the
7910	percentage of completion of the task as a whole
7911	in <link to="#percent" />.
7912
7913	Similarly, you can wait for the completion of a particular
7914	operation via <link to="#waitForOperationCompletion" /> or
7915	for the completion of the whole task via
7916	<link to="#waitForCompletion" />.

7949

8097	name="ISnapshot" extends="$unknown"

8099	wsmap="managed"
8100	>
8101	<desc>
8102	The ISnapshot interface represents a snapshot of the virtual
8103	machine.
8104
8105	Together with the differencing media that are created
8106	when a snapshot is taken, a machine can be brought back to
8107	the exact state it was in when the snapshot was taken.
8108
8109	The ISnapshot interface has no methods, only attributes; snapshots
8110	are controlled through methods of the <link to="IConsole" /> interface
8111	which also manage the media associated with the snapshot.
8112	The following operations exist:
8113
8114	<ul>
8115	<li><link to="IConsole::takeSnapshot"/>: creates a new snapshot
8116	by creating new, empty differencing images for the machine's
8117	media and saving the VM settings and (if the VM is running)
8118	the current VM state in the snapshot.
8119
8120	The differencing images will then receive all data written to
8121	the machine's media, while their parent (base) images
8122	remain unmodified after the snapshot has been taken (see
8123	<link to="IMedium" /> for details about differencing images).
8124	This simplifies restoring a machine to the state of a snapshot:
8125	only the differencing images need to be deleted.
8126
8127	The current machine state is not changed by taking a snapshot.
8128	If the machine is running, it will resume execution after the
8129	snapshot has been taken.
8130	</li>
8131
8132	<li><link to="IConsole::restoreSnapshot"/>: this goes back to
8133	a previous snapshot. This resets the machine's state to that of
8134	the previous snapshot by deleting the differencing image of each
8135	of the machine's media and setting the machine's settings
8136	and state to the state that was saved in the snapshot (if any).
8137
8138	This destroys the machine's current state.
8139	</li>
8140
8141	<li><link to="IConsole::deleteSnapshot"/>: deletes a snapshot
8142	without affecting the current machine state.
8143
8144	This does not change the machine, but instead frees the resources
8145	allocated when the snapshot was taken: the settings and machine state
8146	is deleted (if any), and the snapshot's differencing image for each
8147	of the machine's media gets merged with its parent image.
8148
8149	Neither the current machine state nor other snapshots are affected
8150	by this operation, except that parent media will be modified
8151	to contain the disk data associated with the snapshot being deleted.
8152	</li>
8153	</ul>
8154
8155	Each snapshot contains the settings of the virtual machine (hardware
8156	configuration etc.). In addition, if the machine was running when the
8157	snapshot was taken (<link to="IMachine::state"/> is <link to="MachineState::Running"/>),
8158	the current VM state is saved in the snapshot (similarly to what happens
8159	when a VM's state is saved). The snapshot is then said to
8160	be <i>online</i> because when restoring it, the VM will be running.
8161
8162	If the machine is saved (<link to="MachineState::Saved"/>), the snapshot
8163	receives a copy of the execution state file (<link to="IMachine::stateFilePath"/>).
8164
8165	Otherwise, if the machine was not running (<link to="MachineState::PoweredOff"/>
8166	or <link to="MachineState::Aborted"/>), the snapshot is <i>offline</i>;
8167	it then contains a so-called "zero execution state", representing a
8168	machine that is powered off.
8169
8170	<h3>Snapshot branches and the "current" snapshot</h3>
8171
8172	Snapshots can be chained, whereby every next snapshot is based on the
8173	previous one. This chaining is related to medium branching
8174	(see the <link to="IMedium"/> description) in that every time
8175	a new snapshot is created, a new differencing medium is implicitly
8176	created for all normal media attached to the machine.
8177
8178	Each virtual machine has a "current snapshot", identified by
8179	<link to="IMachine::currentSnapshot"/>. Presently, this is always set
8180	to the last snapshot in the chain. In a future version of VirtualBox,
8181	it will be possible to reset a machine's current state to that of an
8182	earlier snapshot without deleting the current state so that it will be
8183	possible to create alternative snapshot paths in a snapshot tree.
8184
8185	In the current implementation, multiple snapshot branches within one
8186	virtual machine are not allowed. Every machine has a single branch,
8187	and <link to="IConsole::takeSnapshot"/> operation adds a new
8188	snapshot to the top of that branch.

8453	<desc>
8454	The IMedium interface represents virtual storage for a machine's
8455	hard disks, CD/DVD or floppy drives. It will typically represent
8456	a disk image on the host, for example a VDI or VMDK file representing
8457	a virtual hard disk, or an ISO or RAW file representing virtual
8458	removable media, but can also point to a network location (e.g.
8459	for iSCSI targets).
8460
8461	Instances of IMedium are connected to virtual machines by way of
8462	medium attachments (see <link to="IMediumAttachment" />), which link
8463	the storage medium to a particular device slot of a storage controller
8464	of the virtual machine.
8465	In the VirtualBox API, virtual storage is therefore always represented
8466	by the following chain of object links:
8467
8468	<ul>
8469	<li><link to="IMachine::storageControllers"/> contains an array of
8470	storage controllers (IDE, SATA, SCSI, SAS or a floppy controller;
8471	these are instances of <link to="IStorageController"/>).</li>
8472	<li><link to="IMachine::mediumAttachments"/> contains an array of
8473	medium attachments (instances of <link to="IMediumAttachment"/>),
8474	each containing a storage controller from the above array, a
8475	port/device specification, and an instance of IMedium representing
8476	the medium storage (image file).
8477
8478	For removable media, the storage medium is optional; a medium
8479	attachment with no medium represents a CD/DVD or floppy drive
8480	with no medium inserted. By contrast, hard disk attachments
8481	will always have an IMedium object attached.</li>
8482	<li>Each IMedium in turn points to a storage unit (such as a file
8483	on the host computer or a network resource) that holds actual
8484	data. This location is represented by the <link to="#location"/>
8485	attribute.</li>
8486	</ul>
8487
8488	Existing media are opened using <link to="IVirtualBox::openMedium"/>;
8489	new hard disk media can be created with the VirtualBox API using the
8490	<link to="IVirtualBox::createHardDisk"/> method.
8491
8492	CD/DVD and floppy images (ISO and RAW files) are usually created outside
8493	VirtualBox, e.g. by storing a copy of the real medium of the corresponding
8494	type in a regular file.
8495
8496	Only for CD/DVDs and floppies, an IMedium instance can also represent a host
8497	drive; in that case the <link to="#id" /> attribute contains the UUID of
8498	one of the drives in <link to="IHost::DVDDrives" /> or <link to="IHost::floppyDrives" />.
8499
8500	<h3>Known media</h3>
8501
8502	When an existing medium is opened for the first time, it is automatically
8503	remembered by the given VirtualBox installation or, in other words, becomes
8504	a <i>known medium</i>. Known media are stored in the media
8505	registry transparently maintained by VirtualBox and stored in settings
8506	files so that this registry is preserved when VirtualBox is not running.
8507
8508	Newly created virtual media are remembered only when the associated
8509	storage unit is actually created.
8510
8511	All known media can be enumerated using
8512	<link to="IVirtualBox::hardDisks"/>,
8513	<link to="IVirtualBox::DVDImages"/> and
8514	<link to="IVirtualBox::floppyImages"/> attributes. Individual media can be
8515	quickly found using the <link to="IVirtualBox::findMedium"/> method.
8516
8517	Only known media can be attached to virtual machines.
8518
8519	Removing known media from the media registry is performed when the given
8520	medium is closed using the <link to="#close"/> method or when its
8521	associated storage unit is deleted.
8522
8523	<h3>Accessibility checks</h3>
8524
8525	VirtualBox defers media accessibility checks until the <link to="#refreshState" />
8526	method is called explicitly on a medium. This is done to make the VirtualBox object
8527	ready for serving requests as fast as possible and let the end-user
8528	application decide if it needs to check media accessibility right away or not.
8529
8530	As a result, when VirtualBox starts up (e.g. the VirtualBox
8531	object gets created for the first time), all known media are in the
8532	"Inaccessible" state, but the value of the <link to="#lastAccessError"/>
8533	attribute is an empty string because no actual accessibility check has
8534	been made yet.
8535
8536	After calling <link to="#refreshState" />, a medium is considered
8537	<i>accessible</i> if its storage unit can be read. In that case, the
8538	<link to="#state"/> attribute has a value of "Created". If the storage
8539	unit cannot be read (for example, because it is located on a disconnected
8540	network resource, or was accidentally deleted outside VirtualBox),
8541	the medium is considered <i>inaccessible</i>, which is indicated by the
8542	"Inaccessible" state. The exact reason why the medium is inaccessible can be
8543	obtained by reading the <link to="#lastAccessError"/> attribute.
8544
8545	<h3>Medium types</h3>
8546
8547	There are four types of medium behavior (see <link to="MediumType" />):
8548	"normal", "immutable", "writethrough" and "shareable", represented by the
8549	<link to="#type"/> attribute. The type of the medium defines how the
8550	medium is attached to a virtual machine and what happens when a
8551	<link to="ISnapshot">snapshot</link> of the virtual machine with the
8552	attached medium is taken. At the moment DVD and floppy media are always
8553	of type "writethrough".
8554
8555	All media can be also divided in two groups: <i>base</i> media and
8556	<i>differencing</i> media. A base medium contains all sectors of the
8557	medium data in its own storage and therefore can be used independently.
8558	In contrast, a differencing mediun is a "delta" to some other medium and
8559	contains only those sectors which differ from that other medium, which is
8560	then called a <i>parent</i>. The differencing medium is said to be
8561	<i>linked to</i> that parent. The parent may be itself a differencing
8562	medium, thus forming a chain of linked media. The last element in that
8563	chain must always be a base medium. Note that several differencing
8564	media may be linked to the same parent medium.
8565
8566	Differencing media can be distinguished from base media by querying the
8567	<link to="#parent"/> attribute: base media do not have parents they would
8568	depend on, so the value of this attribute is always @c null for them.
8569	Using this attribute, it is possible to walk up the medium tree (from the
8570	child medium to its parent). It is also possible to walk down the tree
8571	using the <link to="#children"/> attribute.
8572
8573	Note that the type of all differencing media is "normal"; all other
8574	values are meaningless for them. Base media may be of any type.
8575
8576	<h3>Creating hard disks</h3>
8577
8578	New base hard disks are created using
8579	<link to="IVirtualBox::createHardDisk"/>. Existing hard disks are
8580	opened using <link to="IVirtualBox::openMedium"/>. Differencing hard
8581	disks are usually implicitly created by VirtualBox when needed but may
8582	also be created explicitly using <link to="#createDiffStorage"/>.
8583
8584	After the hard disk is successfully created (including the storage unit)
8585	or opened, it becomes a known hard disk (remembered in the internal media
8586	registry). Known hard disks can be attached to a virtual machine, accessed
8587	through <link to="IVirtualBox::findMedium"/> or enumerated using the
8588	<link to="IVirtualBox::hardDisks"/> array (only for base hard disks).
8589
8590	The following methods, besides <link to="IMedium::close"/>,
8591	automatically remove the hard disk from the media registry:
8592	<ul>
8593	<li><link to="#deleteStorage"/></li>
8594	<li><link to="#mergeTo"/></li>
8595	</ul>
8596
8597	If the storage unit of the hard disk is a regular file in the host's
8598	file system then the rules stated in the description of the
8599	<link to="IMedium::location"/> attribute apply when setting its value. In
8600	addition, a plain file name without any path may be given, in which case
8601	the <link to="ISystemProperties::defaultHardDiskFolder"> default hard disk
8602	folder</link> will be prepended to it.
8603
8604	<h4>Automatic composition of the file name part</h4>
8605
8606	Another extension to the <link to="IMedium::location"/> attribute is that
8607	there is a possibility to cause VirtualBox to compose a unique value for
8608	the file name part of the location using the UUID of the hard disk. This
8609	applies only to hard disks in <link to="MediumState::NotCreated"/> state,
8610	e.g. before the storage unit is created, and works as follows. You set the
8611	value of the <link to="IMedium::location"/> attribute to a location
8612	specification which only contains the path specification but not the file
8613	name part and ends with either a forward slash or a backslash character.
8614	In response, VirtualBox will generate a new UUID for the hard disk and
8615	compose the file name using the following pattern:
8616	<pre>
8617	<path>/{<uuid>}.<ext>
8618	</pre>
8619	where <tt><path></tt> is the supplied path specification,
8620	<tt><uuid></tt> is the newly generated UUID and <tt><ext></tt>
8621	is the default extension for the storage format of this hard disk. After
8622	that, you may call any of the methods that create a new hard disk storage
8623	unit and they will use the generated UUID and file name.
8624
8625	<h3>Attaching Hard Disks</h3>
8626
8627	Hard disks are attached to virtual machines using the
8628	<link to="IMachine::attachDevice"/> method and detached using the
8629	<link to="IMachine::detachDevice"/> method. Depending on their
8630	<link to="#type"/>, hard disks are attached either
8631	<i>directly</i> or <i>indirectly</i>.
8632
8633	When a hard disk is being attached directly, it is associated with the
8634	virtual machine and used for hard disk operations when the machine is
8635	running. When a hard disk is being attached indirectly, a new differencing
8636	hard disk linked to it is implicitly created and this differencing hard
8637	disk is associated with the machine and used for hard disk operations.
8638	This also means that if <link to="IMachine::attachDevice"/> performs
8639	a direct attachment then the same hard disk will be returned in response
8640	to the subsequent <link to="IMachine::getMedium"/> call; however if
8641	an indirect attachment is performed then
8642	<link to="IMachine::getMedium"/> will return the implicitly created
8643	differencing hard disk, not the original one passed to <link
8644	to="IMachine::attachDevice"/>. In detail:
8645
8646	<ul>
8647	<li><b>Normal base</b> hard disks that do not have children (i.e.
8648	differencing hard disks linked to them) and that are not already
8649	attached to virtual machines in snapshots are attached <b>directly</b>.
8650	Otherwise, they are attached <b>indirectly</b> because having
8651	dependent children or being part of the snapshot makes it impossible
8652	to modify hard disk contents without breaking the integrity of the
8653	dependent party. The <link to="#readOnly"/> attribute allows to
8654	quickly determine the kind of the attachment for the given hard
8655	disk. Note that if a normal base hard disk is to be indirectly
8656	attached to a virtual machine with snapshots then a special
8657	procedure called <i>smart attachment</i> is performed (see below).</li>
8658	<li><b>Normal differencing</b> hard disks are like normal base hard disks:
8659	they are attached <b>directly</b> if they do not have children and are
8660	not attached to virtual machines in snapshots, and <b>indirectly</b>
8661	otherwise. Note that the smart attachment procedure is never performed
8662	for differencing hard disks.</li>
8663	<li><b>Immutable</b> hard disks are always attached <b>indirectly</b> because
8664	they are designed to be non-writable. If an immutable hard disk is
8665	attached to a virtual machine with snapshots then a special
8666	procedure called smart attachment is performed (see below).</li>
8667	<li><b>Writethrough</b> hard disks are always attached <b>directly</b>,
8668	also as designed. This also means that writethrough hard disks cannot
8669	have other hard disks linked to them at all.</li>
8670	<li><b>Shareable</b> hard disks are always attached <b>directly</b>,
8671	also as designed. This also means that shareable hard disks cannot
8672	have other hard disks linked to them at all. They behave almost
8673	like writethrough hard disks, except that shareable hard disks can
8674	be attached to several virtual machines which are running, allowing
8675	concurrent accesses. You need special cluster software running in
8676	the virtual machines to make use of such disks.</li>
8677	</ul>
8678
8679	Note that the same hard disk, regardless of its type, may be attached to
8680	more than one virtual machine at a time. In this case, the machine that is
8681	started first gains exclusive access to the hard disk and attempts to
8682	start other machines having this hard disk attached will fail until the
8683	first machine is powered down.
8684
8685	Detaching hard disks is performed in a <i>deferred</i> fashion. This means
8686	that the given hard disk remains associated with the given machine after a
8687	successful <link to="IMachine::detachDevice"/> call until
8688	<link to="IMachine::saveSettings"/> is called to save all changes to
8689	machine settings to disk. This deferring is necessary to guarantee that
8690	the hard disk configuration may be restored at any time by a call to
8691	<link to="IMachine::discardSettings"/> before the settings
8692	are saved (committed).
8693
8694	Note that if <link to="IMachine::discardSettings"/> is called after
8695	indirectly attaching some hard disks to the machine but before a call to
8696	<link to="IMachine::saveSettings"/> is made, it will implicitly delete
8697	all differencing hard disks implicitly created by
8698	<link to="IMachine::attachDevice"/> for these indirect attachments.
8699	Such implicitly created hard disks will also be immediately deleted when
8700	detached explicitly using the <link to="IMachine::detachDevice"/>
8701	call if it is made before <link to="IMachine::saveSettings"/>. This
8702	implicit deletion is safe because newly created differencing hard
8703	disks do not contain any user data.
8704
8705	However, keep in mind that detaching differencing hard disks that were
8706	implicitly created by <link to="IMachine::attachDevice"/>
8707	before the last <link to="IMachine::saveSettings"/> call will
8708	<b>not</b> implicitly delete them as they may already contain some data
8709	(for example, as a result of virtual machine execution). If these hard
8710	disks are no more necessary, the caller can always delete them explicitly
8711	using <link to="#deleteStorage"/> after they are actually de-associated
8712	from this machine by the <link to="IMachine::saveSettings"/> call.
8713
8714	<h3>Smart Attachment</h3>
8715
8716	When normal base or immutable hard disks are indirectly attached to a
8717	virtual machine then some additional steps are performed to make sure the
8718	virtual machine will have the most recent "view" of the hard disk being
8719	attached. These steps include walking through the machine's snapshots
8720	starting from the current one and going through ancestors up to the first
8721	snapshot. Hard disks attached to the virtual machine in all
8722	of the encountered snapshots are checked whether they are descendants of
8723	the given normal base or immutable hard disk. The first found child (which
8724	is the differencing hard disk) will be used instead of the normal base or
8725	immutable hard disk as a parent for creating a new differencing hard disk
8726	that will be actually attached to the machine. And only if no descendants
8727	are found or if the virtual machine does not have any snapshots then the
8728	normal base or immutable hard disk will be used itself as a parent for
8729	this differencing hard disk.
8730
8731	It is easier to explain what smart attachment does using the
8732	following example:
8733	<pre>
8734	BEFORE attaching B.vdi: AFTER attaching B.vdi:
8735
8736	Snapshot 1 (B.vdi) Snapshot 1 (B.vdi)
8737	Snapshot 2 (D1->B.vdi) Snapshot 2 (D1->B.vdi)
8738	Snapshot 3 (D2->D1.vdi) Snapshot 3 (D2->D1.vdi)
8739	Snapshot 4 (none) Snapshot 4 (none)
8740	CurState (none) CurState (D3->D2.vdi)
8741
8742	NOT

8744	CurState (D3->B.vdi)
8745	</pre>
8746	The first column is the virtual machine configuration before the base hard
8747	disk <tt>B.vdi</tt> is attached, the second column shows the machine after
8748	this hard disk is attached. Constructs like <tt>D1->B.vdi</tt> and similar
8749	mean that the hard disk that is actually attached to the machine is a
8750	differencing hard disk, <tt>D1.vdi</tt>, which is linked to (based on)
8751	another hard disk, <tt>B.vdi</tt>.
8752
8753	As we can see from the example, the hard disk <tt>B.vdi</tt> was detached
8754	from the machine before taking Snapshot 4. Later, after Snapshot 4 was
8755	taken, the user decides to attach <tt>B.vdi</tt> again. <tt>B.vdi</tt> has
8756	dependent child hard disks (<tt>D1.vdi</tt>, <tt>D2.vdi</tt>), therefore
8757	it cannot be attached directly and needs an indirect attachment (i.e.
8758	implicit creation of a new differencing hard disk). Due to the smart
8759	attachment procedure, the new differencing hard disk
8760	(<tt>D3.vdi</tt>) will be based on <tt>D2.vdi</tt>, not on
8761	<tt>B.vdi</tt> itself, since <tt>D2.vdi</tt> is the most recent view of
8762	<tt>B.vdi</tt> existing for this snapshot branch of the given virtual
8763	machine.
8764
8765	Note that if there is more than one descendant hard disk of the given base
8766	hard disk found in a snapshot, and there is an exact device, channel and
8767	bus match, then this exact match will be used. Otherwise, the youngest
8768	descendant will be picked up.
8769
8770	There is one more important aspect of the smart attachment procedure which
8771	is not related to snapshots at all. Before walking through the snapshots
8772	as described above, the backup copy of the current list of hard disk
8773	attachment is searched for descendants. This backup copy is created when
8774	the hard disk configuration is changed for the first time after the last
8775	<link to="IMachine::saveSettings"/> call and used by
8776	<link to="IMachine::discardSettings"/> to undo the recent hard disk
8777	changes. When such a descendant is found in this backup copy, it will be
8778	simply re-attached back, without creating a new differencing hard disk for
8779	it. This optimization is necessary to make it possible to re-attach the
8780	base or immutable hard disk to a different bus, channel or device slot
8781	without losing the contents of the differencing hard disk actually
8782	attached to the machine in place of it.

9140	the state only.
9141
9142	The refresh, if performed, may take a long time (several seconds or even
9143	minutes, depending on the storage unit location and format) because it performs an
9144	accessibility check of the storage unit. This check may cause a significant
9145	delay if the storage unit of the given medium is, for example, a file located
9146	on a network share which is not currently accessible due to connectivity

9197	<method name="lockRead">
9198	<desc>
9199	Locks this medium for reading.
9200
9201	A read lock is shared: many clients can simultaneously lock the
9202	same medium for reading unless it is already locked for writing (see
9203	<link to="#lockWrite"/>) in which case an error is returned.
9204
9205	When the medium is locked for reading, it cannot be modified
9206	from within VirtualBox. This means that any method that changes
9207	the properties of this medium or contents of the storage unit
9208	will return an error (unless explicitly stated otherwise). That
9209	includes an attempt to start a virtual machine that wants to
9210	write to the the medium.
9211
9212	When the virtual machine is started up, it locks for reading all
9213	media it uses in read-only mode. If some medium cannot be locked
9214	for reading, the startup procedure will fail.
9215	A medium is typically locked for reading while it is used by a running
9216	virtual machine but has a depending differencing image that receives
9217	the actual write operations. This way one base medium can have
9218	multiple child differencing images which can be written to
9219	simultaneously. Read-only media such as DVD and floppy images are
9220	also locked for reading only (so they can be in use by multiple
9221	machines simultaneously).
9222
9223	A medium is also locked for reading when it is the source of a
9224	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9225
9226	The medium locked for reading must be unlocked using the <link
9227	to="#unlockRead"/> method. Calls to <link to="#lockRead"/>
9228	can be nested and must be followed by the same number of paired
9229	<link to="#unlockRead"/> calls.
9230
9231	This method sets the medium state (see <link to="#state"/>) to
9232	"LockedRead" on success. The medium's previous state must be
9233	one of "Created", "Inaccessible" or "LockedRead".
9234
9235	Locking an inaccessible medium is not an error; this method performs
9236	a logical lock that prevents modifications of this medium through
9237	the VirtualBox API, not a physical file-system lock of the underlying
9238	storage unit.

9278	<desc>
9279	Locks this medium for writing.
9280
9281	A write lock, as opposed to <link to="#lockRead"/>, is
9282	exclusive: there may be only one client holding a write lock,
9283	and there may be no read locks while the write lock is held.
9284	As a result, read-locking fails if a write lock is held, and
9285	write-locking fails if either a read or another write lock is held.
9286
9287	When a medium is locked for writing, it cannot be modified
9288	from within VirtualBox, and it is not guaranteed that the values
9289	of its properties are up-to-date. Any method that changes the
9290	properties of this medium or contents of the storage unit will
9291	return an error (unless explicitly stated otherwise).
9292
9293	When a virtual machine is started up, it locks for writing all
9294	media it uses to write data to. If any medium could not be locked
9295	for writing, the startup procedure will fail. If a medium has
9296	differencing images, then while the machine is running, only
9297	the last ("leaf") differencing image is locked for writing,
9298	whereas its parents are locked for reading only.
9299
9300	A medium is also locked for writing when it is the target of a
9301	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9302
9303	The medium locked for writing must be unlocked using the <link

9628	Starts merging the contents of this medium and all intermediate

9630
9631	The target medium must be either a descendant of this medium or
9632	its ancestor (otherwise this method will immediately return a failure).
9633	It follows that there are two logical directions of the merge operation:
9634	from ancestor to descendant (<i>forward merge</i>) and from descendant to
9635	ancestor (<i>backward merge</i>). Let us consider the following medium
9636	chain:
9637
9638	<pre>Base <- Diff_1 <- Diff_2</pre>
9639
9640	Here, calling this method on the <tt>Base</tt> medium object with
9641	<tt>Diff_2</tt> as an argument will be a forward merge; calling it on
9642	<tt>Diff_2</tt> with <tt>Base</tt> as an argument will be a backward
9643	merge. Note that in both cases the contents of the resulting medium
9644	will be the same, the only difference is the medium object that takes
9645	the result of the merge operation. In case of the forward merge in the
9646	above example, the result will be written to <tt>Diff_2</tt>; in case of
9647	the backward merge, the result will be written to <tt>Base</tt>. In
9648	other words, the result of the operation is always stored in the target
9649	medium.
9650
9651	Upon successful operation completion, the storage units of all media in
9652	the chain between this (source) medium and the target medium, including
9653	the source medium itself, will be automatically deleted and the
9654	relevant medium objects (including this medium) will become
9655	uninitialized. This means that any attempt to call any of
9656	their methods or attributes will fail with the
9657	<tt>"Object not ready" (E_ACCESSDENIED)</tt> error. Applied to the above
9658	example, the forward merge of <tt>Base</tt> to <tt>Diff_2</tt> will
9659	delete and uninitialize both <tt>Base</tt> and <tt>Diff_1</tt> media.
9660	Note that <tt>Diff_2</tt> in this case will become a base medium
9661	itself since it will no longer be based on any other medium.
9662
9663	Considering the above, all of the following conditions must be met in
9664	order for the merge operation to succeed:
9665	<ul>
9666	<li>
9667	Neither this (source) medium nor any intermediate
9668	differencing medium in the chain between it and the target
9669	medium is attached to any virtual machine.
9670	</li>
9671	<li>
9672	Neither the source medium nor the target medium is an
9673	<link to="MediumType::Immutable"/> medium.
9674	</li>
9675	<li>
9676	The part of the medium tree from the source medium to the
9677	target medium is a linear chain, i.e. all medium in this
9678	chain have exactly one child which is the next medium in this
9679	chain. The only exception from this rule is the target medium in
9680	the forward merge operation; it is allowed to have any number of
9681	child media because the merge operation will not change its
9682	logical contents (as it is seen by the guest OS or by children).
9683	</li>
9684	<li>
9685	None of the involved media are in
9686	<link to="MediumState::LockedRead"/> or
9687	<link to="MediumState::LockedWrite"/> state.
9688	</li>
9689	</ul>
9690
9691	<note>
9692	This (source) medium and all intermediates will be placed to <link

9760	Starts compacting of this medium. This means that the medium is

9791	Resizing usually needs additional disk space, and possibly also

10442	Requests a size and pixel format change.
10443
10444	There are two modes of working with the video buffer of the virtual
10445	machine. The <i>indirect</i> mode implies that the IFramebuffer
10446	implementation allocates a memory buffer for the requested display mode
10447	and provides it to the virtual machine. In <i>direct</i> mode, the
10448	IFramebuffer implementation uses the memory buffer allocated and owned
10449	by the virtual machine. This buffer represents the video memory of the
10450	emulated video adapter (so called <i>guest VRAM</i>). The direct mode is
10451	usually faster because the implementation gets a raw pointer to the
10452	guest VRAM buffer which it can directly use for visualizing the contents
10453	of the virtual display, as opposed to the indirect mode where the
10454	contents of guest VRAM are copied to the memory buffer provided by
10455	the implementation every time a display update occurs.
10456
10457	It is important to note that the direct mode is really fast only when
10458	the implementation uses the given guest VRAM buffer directly, for
10459	example, by blitting it to the window representing the virtual machine's
10460	display, which saves at least one copy operation comparing to the
10461	indirect mode. However, using the guest VRAM buffer directly is not
10462	always possible: the format and the color depth of this buffer may be
10463	not supported by the target window, or it may be unknown (opaque) as in
10464	case of text or non-linear multi-plane VGA video modes. In this case,
10465	the indirect mode (that is always available) should be used as a
10466	fallback: when the guest VRAM contents are copied to the
10467	implementation-provided memory buffer, color and format conversion is
10468	done automatically by the underlying code.
10469
10470	The @a pixelFormat parameter defines whether the direct mode is
10471	available or not. If @a pixelFormat is <link
10472	to="FramebufferPixelFormat::Opaque"/> then direct access to the guest
10473	VRAM buffer is not available -- the @a VRAM, @a bitsPerPixel and
10474	@a bytesPerLine parameters must be ignored and the implementation must use
10475	the indirect mode (where it provides its own buffer in one of the
10476	supported formats). In all other cases, @a pixelFormat together with
10477	@a bitsPerPixel and @a bytesPerLine define the format of the video memory
10478	buffer pointed to by the @a VRAM parameter and the implementation is
10479	free to choose which mode to use. To indicate that this frame buffer uses
10480	the direct mode, the implementation of the <link to="#usesGuestVRAM"/>
10481	attribute must return @c true and <link to="#address"/> must
10482	return exactly the same address that is passed in the @a VRAM parameter
10483	of this method; otherwise it is assumed that the indirect strategy is
10484	chosen.
10485
10486	The @a width and @a height parameters represent the size of the
10487	requested display mode in both modes. In case of indirect mode, the
10488	provided memory buffer should be big enough to store data of the given
10489	display mode. In case of direct mode, it is guaranteed that the given
10490	@a VRAM buffer contains enough space to represent the display mode of the
10491	given size. Note that this frame buffer's <link to="#width"/> and <link
10492	to="#height"/> attributes must return exactly the same values as
10493	passed to this method after the resize is completed (see below).
10494
10495	The @a finished output parameter determines if the implementation has
10496	finished resizing the frame buffer or not. If, for some reason, the
10497	resize cannot be finished immediately during this call, @a finished
10498	must be set to @c false, and the implementation must call
10499	<link to="IDisplay::resizeCompleted"/> after it has returned from
10500	this method as soon as possible. If @a finished is @c false, the
10501	machine will not call any frame buffer methods until
10502	<link to="IDisplay::resizeCompleted"/> is called.
10503
10504	Note that if the direct mode is chosen, the <link to="#bitsPerPixel"/>,
10505	<link to="#bytesPerLine"/> and <link to="#pixelFormat"/> attributes of
10506	this frame buffer must return exactly the same values as specified in the
10507	parameters of this method, after the resize is completed. If the
10508	indirect mode is chosen, these attributes must return values describing
10509	the format of the implementation's own memory buffer <link
10510	to="#address"/> points to. Note also that the <link to="#bitsPerPixel"/>
10511	value must always correlate with <link to="#pixelFormat"/>. Note that
10512	the <link to="#pixelFormat"/> attribute must never return <link
10513	to="FramebufferPixelFormat::Opaque"/> regardless of the selected mode.
10514

11162	The ISerialPort interface represents the virtual serial port device.
11163
11164	The virtual serial port device acts like an ordinary serial port
11165	inside the virtual machine. This device communicates to the real
11166	serial port hardware in one of two modes: host pipe or host device.
11167
11168	In host pipe mode, the #path attribute specifies the path to the pipe on
11169	the host computer that represents a serial port. The #server attribute
11170	determines if this pipe is created by the virtual machine process at
11171	machine startup or it must already exist before starting machine
11172	execution.
11173
11174	In host device mode, the #path attribute specifies the name of the
11175	serial port device on the host computer.
11176
11177	There is also a third communication mode: the disconnected mode. In this
11178	mode, the guest OS running inside the virtual machine will be able to
11179	detect the serial port, but all port write operations will be discarded
11180	and all port read operations will return no data.

11250	The IParallelPort interface represents the virtual parallel port device.
11251
11252	The virtual parallel port device acts like an ordinary parallel port
11253	inside the virtual machine. This device communicates to the real
11254	parallel port hardware using the name of the parallel device on the host
11255	computer specified in the #path attribute.
11256
11257	Each virtual parallel port device is assigned a base I/O address and an
11258	IRQ number that will be reported to the guest operating system and used
11259	to operate the given parallel port from within the virtual machine.

11674	<desc>
11675	The IUSBDeviceFilter interface represents an USB device filter used
11676	to perform actions on a group of USB devices.
11677
11678	This type of filters is used by running virtual machines to
11679	automatically capture selected USB devices once they are physically
11680	attached to the host computer.
11681
11682	A USB device is matched to the given device filter if and only if all
11683	attributes of the device match the corresponding attributes of the
11684	filter (that is, attributes are joined together using the logical AND
11685	operation). On the other hand, all together, filters in the list of
11686	filters carry the semantics of the logical OR operation. So if it is
11687	desirable to create a match like "this vendor id OR this product id",
11688	one needs to create two filters and specify "any match" (see below)
11689	for unused attributes.
11690
11691	All filter attributes used for matching are strings. Each string
11692	is an expression representing a set of values of the corresponding
11693	device attribute, that will match the given filter. Currently, the
11694	following filtering expressions are supported:
11695
11696	<ul>
11697	<li><i>Interval filters</i>. Used to specify valid intervals for
11698	integer device attributes (Vendor ID, Product ID and Revision).
11699	The format of the string is:
11700
11701	<tt>int:((m)\|([m]-[n]))(,(m)\|([m]-[n]))*</tt>
11702
11703	where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
11704	(starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
11705	or decimal (otherwise) form, so that <tt>m < n</tt>. If <tt>m</tt>
11706	is omitted before a dash (<tt>-</tt>), the minimum possible integer
11707	is assumed; if <tt>n</tt> is omitted after a dash, the maximum
11708	possible integer is assumed.
11709	</li>
11710	<li><i>Boolean filters</i>. Used to specify acceptable values for
11711	boolean device attributes. The format of the string is:
11712
11713	<tt>true\|false\|yes\|no\|0\|1</tt>
11714
11715	</li>
11716	<li><i>Exact match</i>. Used to specify a single value for the given
11717	device attribute. Any string that doesn't start with <tt>int:</tt>
11718	represents the exact match. String device attributes are compared to
11719	this string including case of symbols. Integer attributes are first
11720	converted to a string (see individual filter attributes) and then
11721	compared ignoring case.
11722
11723	</li>
11724	<li><i>Any match</i>. Any value of the corresponding device attribute
11725	will match the given filter. An empty or @c null string is
11726	used to construct this type of filtering expressions.
11727
11728	</li>
11729	</ul>
11730
11731	<note>
11732	On the Windows host platform, interval filters are not currently
11733	available. Also all string filter attributes
11734	(<link to="#manufacturer"/>, <link to="#product"/>,
11735	<link to="#serialNumber"/>) are ignored, so they behave as
11736	<i>any match</i> no matter what string expression is specified.

11844	USB device state. This enumeration represents all possible states
11845	of the USB device physically attached to the host computer regarding
11846	its state on the host computer and availability to guest computers
11847	(all currently running virtual machines).
11848
11849	Once a supported USB device is attached to the host, global USB
11850	filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
11851	either ignore the device, or put it to USBDeviceState_Held state, or do
11852	nothing. Unless the device is ignored by global filters, filters of all
11853	currently running guests (<link to="IUSBController::deviceFilters"/>) are
11854	activated that can put it to USBDeviceState_Captured state.
11855
11856	If the device was ignored by global filters, or didn't match
11857	any filters at all (including guest ones), it is handled by the host
11858	in a normal way. In this case, the device state is determined by
11859	the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
11860	or USBDeviceState_Available, depending on the current device usage.
11861
11862	Besides auto-capturing based on filters, the device can be manually
11863	captured by guests (<link to="IConsole::attachUSBDevice"/>) if its
11864	state is USBDeviceState_Busy, USBDeviceState_Available or
11865	USBDeviceState_Held.
11866
11867	<note>
11868	Due to differences in USB stack implementations in Linux and Win32,
11869	states USBDeviceState_Busy and USBDeviceState_vailable are applicable
11870	only to the Linux version of the product. This also means that (<link
11871	to="IConsole::attachUSBDevice"/>) can only succeed on Win32 if the
11872	device state is USBDeviceState_Held.

12175	The ISharedFolder interface represents a folder in the host computer's
12176	file system accessible from the guest OS running inside a virtual
12177	machine using an associated logical name.
12178
12179	There are three types of shared folders:
12180	<ul>
12181	<li><i>Global</i> (<link to="IVirtualBox::sharedFolders"/>), shared
12182	folders available to all virtual machines.</li>
12183	<li><i>Permanent</i> (<link to="IMachine::sharedFolders"/>),
12184	VM-specific shared folders available to the given virtual machine at
12185	startup.</li>
12186	<li><i>Transient</i> (<link to="IConsole::sharedFolders"/>),
12187	VM-specific shared folders created in the session context (for
12188	example, when the virtual machine is running) and automatically
12189	discarded when the session is closed (the VM is powered off).</li>
12190	</ul>
12191
12192	Logical names of shared folders must be unique within the given scope
12193	(global, permanent or transient). However, they do not need to be unique
12194	across scopes. In this case, the definition of the shared folder in a
12195	more specific scope takes precedence over definitions in all other
12196	scopes. The order of precedence is (more specific to more general):
12197	<ol>
12198	<li>Transient definitions</li>
12199	<li>Permanent definitions</li>
12200	<li>Global definitions</li>
12201	</ol>
12202
12203	For example, if MyMachine has a shared folder named
12204	<tt>C_DRIVE</tt> (that points to <tt>C:\\</tt>), then creating a
12205	transient shared folder named <tt>C_DRIVE</tt> (that points
12206	to <tt>C:\\\\WINDOWS</tt>) will change the definition
12207	of <tt>C_DRIVE</tt> in the guest OS so
12208	that <tt>\\\\VBOXSVR\\C_DRIVE</tt> will give access
12209	to <tt>C:\\WINDOWS</tt> instead of <tt>C:\\</tt> on the host
12210	PC. Removing the transient shared folder <tt>C_DRIVE</tt> will restore
12211	the previous (permanent) definition of <tt>C_DRIVE</tt> that points
12212	to <tt>C:\\</tt> if it still exists.
12213
12214	Note that permanent and transient shared folders of different machines
12215	are in different name spaces, so they don't overlap and don't need to
12216	have unique logical names.
12217
12218	<note>

12701	>
12702	<desc>
12703	The ISession interface represents a client process and allows for locking
12704	virtual machines (represented by IMachine objects) to prevent conflicting
12705	changes to the machine.
12706
12707	Any caller wishing to manipulate a virtual machine needs to create a session
12708	object first, which lives in its own process space. Such session objects are
12709	then associated with <link to="IMachine" /> objects living in the VirtualBox
12710	server process to coordinate such changes.
12711
12712	There are two typical scenarios in which sessions are used:
12713
12714	<ul>
12715	<li>To alter machine settings or control a running virtual machine, one
12716	needs to lock a machine for a given session (client process) by calling
12717	<link to="IMachine::lockMachine"/>.
12718
12719	Whereas multiple sessions may control a running virtual machine, only
12720	one process can obtain a write lock on the machine to prevent conflicting
12721	changes. A write lock is also needed if a process wants to actually run a
12722	virtual machine in its own context, such as the VirtualBox GUI or
12723	VBoxHeadless front-ends. They must also lock a machine for their own
12724	sessions before they are allowed to power up the virtual machine.
12725
12726	As a result, no machine settings can be altered while another process is
12727	already using it, either because that process is modifying machine settings
12728	or because the machine is running.
12729	</li>
12730	<li>
12731	To start a VM using one of the existing VirtualBox front-ends (e.g. the
12732	VirtualBox GUI or VBoxHeadless), one would use
12733	<link to="IMachine::launchVMProcess"/>, which also takes a session object
12734	as its first parameter. This session then identifies the caller and lets the
12735	caller control the started machine (for example, pause machine execution or
12736	power it down) as well as be notified about machine execution state changes.
12737	</li>
12738	</ul>
12739
12740	How sessions objects are created in a client process depends on whether you use
12741	the Main API via COM or via the webservice:
12742
12743	<ul>
12744	<li>When using the COM API directly, an object of the Session class from the
12745	VirtualBox type library needs to be created. In regular COM C++ client code,
12746	this can be done by calling <tt>createLocalObject()</tt>, a standard COM API.
12747	This object will then act as a local session object in further calls to open
12748	a session.
12749	</li>
12750
12751	<li>In the webservice, the session manager (IWebsessionManager) instead creates
12752	a session object automatically whenever <link to="IWebsessionManager::logon" />
12753	is called. A managed object reference to that session object can be retrieved by
12754	calling <link to="IWebsessionManager::getSessionObject" />.
12755	</li>

13185	The IPerformanceCollector interface represents a service that collects
13186	and stores performance metrics data.
13187
13188	Performance metrics are associated with objects of interfaces like IHost
13189	and IMachine. Each object has a distinct set of performance metrics. The
13190	set can be obtained with <link to="IPerformanceCollector::getMetrics"/>.
13191
13192	Metric data is collected at the specified intervals and is retained
13193	internally. The interval and the number of retained samples can be set
13194	with <link to="IPerformanceCollector::setupMetrics" />. Both metric data
13195	and collection settings are not persistent, they are discarded as soon as
13196	VBoxSVC process terminates. Moreover, metric settings and data associated
13197	with a particular VM only exist while VM is running. They disappear as
13198	soon as VM shuts down. It is not possible to set up metrics for machines
13199	that are powered off. One needs to start VM first, then set up metric
13200	collection parameters.
13201
13202	Metrics are organized hierarchically, with each level separated by a
13203	slash (/) character. Generally, the scheme for metric names is like this:
13204
13205	<tt>Category/Metric[/SubMetric][:aggregation]</tt>
13206
13207	"Category/Metric" together form the base metric name. A base metric is
13208	the smallest unit for which a sampling interval and the number of
13209	retained samples can be set. Only base metrics can be enabled and
13210	disabled. All sub-metrics are collected when their base metric is
13211	collected. Collected values for any set of sub-metrics can be queried
13212	with <link to="IPerformanceCollector::queryMetricsData" />.
13213
13214	For example "CPU/Load/User:avg" metric name stands for the "CPU"
13215	category, "Load" metric, "User" submetric, "average" aggregate. An
13216	aggregate function is computed over all retained data. Valid aggregate
13217	functions are:
13218
13219	<ul>
13220	<li>avg -- average</li>
13221	<li>min -- minimum</li>
13222	<li>max -- maximum</li>
13223	</ul>
13224
13225	When setting up metric parameters, querying metric data, enabling or
13226	disabling metrics wildcards can be used in metric names to specify a
13227	subset of metrics. For example, to select all CPU-related metrics
13228	use <tt>CPU/</tt>, all averages can be queried using <tt>:avg</tt> and
13229	so on. To query metric values without aggregates <tt>*:</tt> can be used.
13230
13231	The valid names for base metrics are:
13232
13233	<ul>
13234	<li>CPU/Load</li>
13235	<li>CPU/MHz</li>
13236	<li>RAM/Usage</li>
13237	</ul>
13238
13239	The general sequence for collecting and retrieving the metrics is:
13240	<ul>
13241	<li>
13242	Obtain an instance of IPerformanceCollector with
13243	<link to="IVirtualBox::performanceCollector" />
13244	</li>
13245	<li>
13246	Allocate and populate an array with references to objects the metrics
13247	will be collected for. Use references to IHost and IMachine objects.
13248	</li>
13249	<li>
13250	Allocate and populate an array with base metric names the data will
13251	be collected for.
13252	</li>

14047	Abstract parent interface for VirtualBox events. Actual events will typically implement
14048	a more specific interface which derives from this (see below).
14049
14050	<b>Introduction to VirtualBox events</b>
14051
14052	Generally speaking, an event (represented by this interface) signals that something
14053	happened, while an event listener (see <link to="IEventListener" />) represents an
14054	entity that is interested in certain events. In order for this to work with
14055	unidirectional protocols (i.e. web services), the concepts of passive and active
14056	listener are used.
14057
14058	Event consumers can register themselves as listeners, providing an array of
14059	events they are interested in (see <link to="IEventSource::registerListener" />).
14060	When an event triggers, the listener is notified about the event. The exact
14061	mechanism of the notification depends on whether the listener was registered as
14062	an active or passive listener:
14063
14064	<ul>
14065	<li>An active listener is very similar to a callback: it is a function invoked
14066	by the API. As opposed to the callbacks that were used in the API before
14067	VirtualBox 3.3 however, events are now objects with an interface hierarchy.
14068	</li>
14069
14070	<li>Passive listeners are somewhat tricker to implement, but do not require
14071	a client function to be callable, which is not an option with scripting
14072	languages or web service clients. Internally the <link to="IEventSource" />
14073	implementation maintains an event queue for each passive listener, and
14074	newly arrived events are put in this queue. When the listener calls
14075	<link to="IEventSource::getEvent"/>, first element from its internal event
14076	queue is returned. When the client completes processing of an event,
14077	the <link to="IEventSource::eventProcessed" /> function must be called,
14078	acknowledging that the event was processed. It supports implementing
14079	waitable events. On passive listener unregistration, all events from its
14080	queue are auto-acknowledged.
14081	</li>
14082	</ul>
14083
14084	Waitable events are useful in situations where the event generator wants to track
14085	delivery or a party wants to wait until all listeners have completed the event. A
14086	typical example would be a vetoable event (see <link to="IVetoEvent" />) where a
14087	listeners might veto a certain action, and thus the event producer has to make
14088	sure that all listeners have processed the event and not vetoed before taking
14089	the action.
14090
14091	A given event may have both passive and active listeners at the same time.
14092
14093	<b>Using events</b>
14094
14095	Any VirtualBox object capable of producing externally visible events provides an
14096	@c eventSource read-only attribute, which is of the type <link to="IEventSource" />.
14097	This event source object is notified by VirtualBox once something has happened, so
14098	consumers may register event listeners with this event source. To register a listener,
14099	an object implementing the <link to="IEventListener" /> interface must be provided.
14100	For active listeners, such an object is typically created by the consumer, while for
14101	passive listeners <link to="IEventSource::createListener" /> should be used. Please
14102	note that a listener created with @c createListener() must not be used as an active listener.
14103
14104	Once created, the listener must be registered to listen for the desired events
14105	(see <link to="IEventSource::registerListener" />), providing an array of
14106	<link to="VBoxEventType" /> enums. Those elements can either be the individual
14107	event IDs or wildcards matching multiple event IDs.
14108
14109	After registration, the callback's <link to="IEventListener::handleEvent" /> method is
14110	called automatically when the event is triggered, while passive listeners have to call
14111	<link to="IEventSource::getEvent" /> and <link to="IEventSource::eventProcessed" /> in
14112	an event processing loop.
14113
14114	The IEvent interface is an abstract parent interface for all such VirtualBox events
14115	coming in. As a result, the standard use pattern inside <link to="IEventListener::handleEvent" />
14116	or the event processing loop is to check the <link to="#type" /> attribute of the event and
14117	then cast to the appropriate specific interface using @c QueryInterface().

14137	Waitable events are needed when one need to be able to wait for particular event processed,

14409	The @a shape buffer contains a 1-bpp (bits per pixel) AND mask
14410	followed by a 32-bpp XOR (color) mask.
14411
14412	For pointers without alpha channel the XOR mask pixels are 32
14413	bit values: (lsb)BGR0(msb). For pointers with alpha channel
14414	the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
14415
14416	An AND mask is used for pointers with alpha channel, so if the
14417	callback does not support alpha, the pointer could be
14418	displayed as a normal color pointer.
14419
14420	The AND mask is a 1-bpp bitmap with byte aligned scanlines. The
14421	size of the AND mask therefore is <tt>cbAnd = (width + 7) / 8 *
14422	height</tt>. The padding bits at the end of each scanline are
14423	undefined.
14424
14425	The XOR mask follows the AND mask on the next 4-byte aligned
14426	offset: <tt>uint8_t *pXor = pAnd + (cbAnd + 3) & ~3</tt>.
14427	Bytes in the gap between the AND and the XOR mask are undefined.
14428	The XOR mask scanlines have no gap between them and the size of
14429	the XOR mask is: <tt>cXor = width * 4 * height</tt>.

14744	<desc>
14745	Notification when an error happens during the virtual
14746	machine execution.
14747
14748	There are three kinds of runtime errors:
14749	<ul>
14750	<li><i>fatal</i></li>
14751	<li><i>non-fatal with retry</i></li>
14752	<li><i>non-fatal warnings</i></li>
14753	</ul>
14754
14755	<b>Fatal</b> errors are indicated by the @a fatal parameter set
14756	to @c true. In case of fatal errors, the virtual machine
14757	execution is always paused before calling this notification, and
14758	the notification handler is supposed either to immediately save
14759	the virtual machine state using <link to="IConsole::saveState"/>
14760	or power it off using <link to="IConsole::powerDown"/>.
14761	Resuming the execution can lead to unpredictable results.
14762
14763	<b>Non-fatal</b> errors and warnings are indicated by the
14764	@a fatal parameter set to @c false. If the virtual machine
14765	is in the Paused state by the time the error notification is
14766	received, it means that the user can <i>try to resume</i> the machine
14767	execution after attempting to solve the problem that caused the
14768	error. In this case, the notification handler is supposed
14769	to show an appropriate message to the user (depending on the
14770	value of the @a id parameter) that offers several actions such
14771	as <i>Retry</i>, <i>Save</i> or <i>Power Off</i>. If the user
14772	wants to retry, the notification handler should continue
14773	the machine execution using the <link to="IConsole::resume"/>
14774	call. If the machine execution is not Paused during this
14775	notification, then it means this notification is a <i>warning</i>
14776	(for example, about a fatal condition that can happen very soon);
14777	no immediate action is required from the user, the machine
14778	continues its normal execution.
14779
14780	Note that in either case the notification handler
14781	<b>must not</b> perform any action directly on a thread
14782	where this notification is called. Everything it is allowed to
14783	do is to post a message to another thread that will then talk
14784	to the user and take the corresponding action.
14785
14786	Currently, the following error identifiers are known:
14787	<ul>
14788	<li><tt>"HostMemoryLow"</tt></li>
14789	<li><tt>"HostAudioNotResponding"</tt></li>

14980	This method must set @a winId to zero if it has performed all
