VirtualBox.xidl@ 32857

Last change on this file since 32857 was 32852, checked in by vboxsync, 14 years ago

Guest Execution:

Implemented "ignore orphaned childs" flag (--flags ignoreorphanedchilds); this flag will tell the host to not bitch about an executed process which still is alive when VBoxService (or the entire guest OS) shuts down.
Fixed shutdown/notification hang when waiting for std output which never arrives.

Property svn:eol-style set to native

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	\| \| ^ \| ^ \|

516	\| \| +-- Saving <--------[takeSnapshot()]<-------+---------------------+
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.

1168	>
1169	<desc>
1170	The IVirtualBoxErrorInfo interface represents extended error information.
1171
1172	Extended error information can be set by VirtualBox components after
1173	unsuccessful or partially successful method invocation. This information
1174	can be retrieved by the calling party as an IVirtualBoxErrorInfo object
1175	and then shown to the client in addition to the plain 32-bit result code.
1176
1177	In MS COM, this interface extends the IErrorInfo interface,
1178	in XPCOM, it extends the nsIException interface. In both cases,
1179	it provides a set of common attributes to retrieve error
1180	information.
1181
1182	Sometimes invocation of some component's method may involve methods of
1183	other components that may also fail (independently of this method's
1184	failure), or a series of non-fatal errors may precede a fatal error that
1185	causes method failure. In cases like that, it may be desirable to preserve
1186	information about all errors happened during method invocation and deliver
1187	it to the caller. The <link to="#next"/> attribute is intended
1188	specifically for this purpose and allows to represent a chain of errors
1189	through a single IVirtualBoxErrorInfo object set after method invocation.
1190
1191	Note that errors are stored to a chain in the reverse order, i.e. the
1192	initial error object you query right after method invocation is the last
1193	error set by the callee, the object it points to in the @a next attribute
1194	is the previous error and so on, up to the first error (which is the last
1195	in the chain).

1203	always. For example, on Win32, CoCreateInstance() will most
1204	likely return E_NOINTERFACE upon unsuccessful component
1205	instantiation attempt, but not the value the component factory
1206	returned. Value is typed 'long', not 'result',
1207	to make interface usable from scripting languages.

1531	<li>
1532	Configure the machine using the appropriate attributes and methods.
1533	</li>
1534
1535	<li>
1536	Call <link to="IMachine::saveSettings" /> to write the settings
1537	to the machine's XML settings file. The configuration of the newly
1538	created machine will not be saved to disk until this method is
1539	called.
1540	</li>
1541
1542	<li>
1543	Call <link to="#registerMachine" /> to add the machine to the list
1544	of machines known to VirtualBox.
1545	</li>
1546	</ol>
1547
1548	You should specify valid name for the newly created machine when calling
1549	this method. See the <link to="IMachine::name"/> attribute description
1550	for more details about the machine name.
1551
1552	The specified guest OS type identifier must match an ID of one of known
1553	guest OS types listed in the <link to="IVirtualBox::guestOSTypes"/>
1554	array.
1555
1556	Every machine has a <i>settings file</i> that is used to store
1557	the machine configuration. This file is stored in a directory called the
1558	<i>machine settings subfolder</i>. Both the settings subfolder and file
1559	will have a name that corresponds to the name of the virtual machine.
1560	You can specify where to create the machine setting subfolder using the
1561	@a baseFolder argument. The base folder can be absolute (full path) or
1562	relative to the <link to="IVirtualBox::homeFolder">VirtualBox home
1563	directory</link>.
1564
1565	If @a baseFolder is a @c null or empty string (which is recommended), the
1566	<link to="ISystemProperties::defaultMachineFolder">default machine
1567	settings folder</link> will be used as a base folder for the created
1568	machine. Otherwise the given base folder will be used. In either case,
1569	the full path to the resulting settings file has the following
1570	structure:
1571	<pre>
1572	<base_folder>/<machine_name>/<machine_name>.xml
1573	</pre>
1574
1575	Note that if the resulting settings file already exists, this method
1576	will fail with <link to="VBOX_E_FILE_ERROR"/>.
1577
1578	Optionally, you may specify an UUID of to assign to the created machine.
1579	However, this is not recommended and you should normally pass an empty
1580	(@c null) UUID to this method so that a new UUID will be automatically
1581	generated for every created machine. You can use UUID
1582	00000000-0000-0000-0000-000000000000 as @c null value.
1583
1584	<note>
1585	There is no way to change the name of the settings file or
1586	subfolder of the created machine directly.

1725	to virtual machines, you must call one of the following methods to

1776	Opens a medium from an existing storage location.
1777
1778	Once a medium has been opened, it can be passed to other VirtualBox
1779	methods, in particular to <link to="IMachine::attachDevice" />.
1780
1781	Depending on the given device type, the file at the storage location
1782	must be in one of the media formats understood by VirtualBox:
1783
1784	<ul>
1785	<li>With a "HardDisk" device type, the file must be a hard disk image
1786	in one of the formats supported by VirtualBox (see
1787	<link to="ISystemProperties::mediumFormats" />).
1788	After this method succeeds, if the medium is a base medium, it
1789	will be added to the <link to="#hardDisks"/> array attribute. </li>
1790	<li>With a "DVD" device type, the file must be an ISO 9960 CD/DVD image.
1791	After this method succeeds, the medium will be added to the
1792	<link to="#DVDImages"/> array attribute.</li>
1793	<li>With a "Floppy" device type, the file must be an RAW floppy image.
1794	After this method succeeds, the medium will be added to the
1795	<link to="#floppyImages"/> array attribute.</li>
1796	</ul>
1797
1798	After having been opened, the medium can be found by the <link to="#findMedium"/>
1799	method and can be attached to virtual machines. See <link to="IMedium" /> for more details.
1800
1801	The UUID of the newly opened medium will either be retrieved from the
1802	storage location, if the format supports it (e.g. for hard disk images),
1803	or a new UUID will be randomly generated (e.g. for ISO and RAW files).
1804	If for some reason you need to change the medium's UUID, use
1805	<link to="IMedium::setIDs" />.
1806
1807	If a differencing hard disk medium is to be opened by this method, the
1808	operation will succeed only if its parent medium and all ancestors,
1809	if any, are already known to this VirtualBox installation (for example,
1810	were opened by this method before).
1811
1812	This method attempts to guess the storage format of the specified medium
1813	by reading medium data at the specified location.
1814
1815	If @a accessMode is ReadWrite (which it should be for hard disks and floppies),
1816	the image is opened for read/write access and must have according permissions,
1817	as VirtualBox may actually write status information into the disk's metadata
1818	sections.
1819
1820	Note that write access is required for all typical hard disk usage in VirtualBox,
1821	since VirtualBox may need to write metadata such as a UUID into the image.
1822	The only exception is opening a source image temporarily for copying and
1823	cloning (see <link to="IMedium::cloneTo" /> when the image will be closed
1824	again soon.
1825
1826	The format of the location string is storage format specific. See
1827	<link to="IMedium::location"/>, IMedium and
1828	<link to="ISystemProperties::defaultHardDiskFolder"/> for more details.
1829
1830	Prior to VirtualBox 3.3, opening a medium added it to a global media
1831	registry in the VirtualBox.xml file, which was shared between
1832	all machines and made transporting machines and their media from one
1833	host to another difficult.
1834
1835	Starting with VirtualBox 3.3, media are only added to a registry when
1836	they are attached to a machine. Machines created with VirtualBox 3.3
1837	or later can have their own media registry. As a result, a medium attached
1838	to such a machine will be remembered in that machine's XML settings file.
1839	Media attached to older machines will continue to be added to the global
1840	registry.

2057	Blocks the caller until any of the properties represented by the
2058	@a what argument changes the value or until the given timeout interval
2059	expires.
2060
2061	The @a what argument is a comma separated list of property masks that
2062	describe properties the caller is interested in. The property mask is
2063	a string in the following format:
2064
2065	<pre>
2066	[[group.]subgroup.]name
2067	</pre>
2068
2069	where @c name is the property name and @c group, @c subgroup are zero
2070	or more property group specifiers. Each element (group or name) in
2071	the property mask may be either a Latin string or an asterisk symbol
2072	(@c "*") which is used to match any string for the given element. A
2073	property mask that doesn't contain asterisk symbols represents a
2074	single fully qualified property name.
2075
2076	Groups in the fully qualified property name go from more generic (the
2077	left-most part) to more specific (the right-most part). The first
2078	element is usually a name of the object the property belongs to. The
2079	second element may be either a property name, or a child object name,
2080	or an index if the preceding element names an object which is one of
2081	many objects of the same type. This way, property names form a
2082	hierarchy of properties. Here are some examples of property names:
2083
2084	<table>
2085	<tr>
2086	<td><tt>VirtualBox.version</tt></td>
2087	<td><link to="IVirtualBox::version"/> property</td>
2088	</tr>
2089	<tr>
2090	<td><tt>Machine.<UUID>.name</tt></td>
2091	<td><link to="IMachine::name"/> property of the machine with the
2092	given UUID</td>
2093	</tr>
2094	</table>
2095
2096	Most property names directly correspond to the properties of objects
2097	(components) provided by the VirtualBox library and may be used to
2098	track changes to these properties. However, there may be
2099	pseudo-property names that don't correspond to any existing object's
2100	property directly, as well as there may be object properties that
2101	don't have a corresponding property name that is understood by this
2102	method, and therefore changes to such properties cannot be
2103	tracked. See individual object's property descriptions to get a
2104	fully qualified property name that can be used with this method (if
2105	any).
2106
2107	There is a special property mask @c "*" (i.e. a string consisting of a
2108	single asterisk symbol) that can be used to match all properties.
2109	Below are more examples of property masks:
2110
2111	<table>
2112	<tr>
2113	<td><tt>VirtualBox.*</tt></td>
2114	<td>Track all properties of the VirtualBox object</td>
2115	</tr>
2116	<tr>
2117	<td><tt>Machine.*.name</tt></td>
2118	<td>Track changes to the <link to="IMachine::name"/> property of
2119	all registered virtual machines</td>
2120	</tr>

2397	Represents a platform-independent appliance in OVF format. An instance of this is returned
2398	by <link to="IVirtualBox::createAppliance" />, which can then be used to import and export
2399	virtual machines within an appliance with VirtualBox.
2400
2401	The OVF standard suggests two different physical file formats:
2402
2403	<ol>
2404	<li>If the appliance is distributed as a set of files, there must be at least one XML descriptor
2405	file that conforms to the OVF standard and carries an <tt>.ovf</tt> file extension. If
2406	this descriptor file references other files such as disk images, as OVF appliances typically
2407	do, those additional files must be in the same directory as the descriptor file.</li>
2408
2409	<li>If the appliance is distributed as a single file, it must be in TAR format and have the
2410	<tt>.ova</tt> file extension. This TAR file must then contain at least the OVF descriptor
2411	files and optionally other files.
2412
2413	At this time, VirtualBox does not not yet support the packed (TAR) variant; support will
2414	be added with a later version.</li>
2415	</ol>
2416
2417	<b>Importing</b> an OVF appliance into VirtualBox as instances of
2418	<link to="IMachine" /> involves the following sequence of API calls:
2419
2420	<ol>
2421	<li>Call <link to="IVirtualBox::createAppliance" />. This will create an empty IAppliance object.
2422	</li>
2423
2424	<li>On the new object, call <link to="#read" /> with the full path of the OVF file you
2425	would like to import. So long as this file is syntactically valid, this will succeed
2426	and fill the appliance object with the parsed data from the OVF file.
2427	</li>
2428
2429	<li>Next, call <link to="#interpret" />, which analyzes the OVF data and sets up the
2430	contents of the IAppliance attributes accordingly. These can be inspected by a
2431	VirtualBox front-end such as the GUI, and the suggestions can be displayed to the
2432	user. In particular, the <link to="#virtualSystemDescriptions" /> array contains
2433	instances of <link to="IVirtualSystemDescription" /> which represent the virtual
2434	systems (machines) in the OVF, which in turn describe the virtual hardware prescribed
2435	by the OVF (network and hardware adapters, virtual disk images, memory size and so on).
2436	The GUI can then give the user the option to confirm and/or change these suggestions.
2437	</li>
2438
2439	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
2440	virtual system (machine) to override the suggestions made by the interpret() routine.
2441	</li>
2442
2443	<li>Finally, call <link to="#importMachines" /> to create virtual machines in
2444	VirtualBox as instances of <link to="IMachine" /> that match the information in the
2445	virtual system descriptions. After this call suceeded, the UUIDs of the machines created
2446	can be found in the <link to="#machines" /> array attribute.
2447	</li>
2448	</ol>
2449
2450	<b>Exporting</b> VirtualBox machines into an OVF appliance involves the following steps:
2451
2452	<ol>
2453	<li>As with importing, first call <link to="IVirtualBox::createAppliance" /> to create
2454	an empty IAppliance object.
2455	</li>
2456
2457	<li>For each machine you would like to export, call <link to="IMachine::export" />
2458	with the IAppliance object you just created. Each such call creates one instance of
2459	<link to="IVirtualSystemDescription" /> inside the appliance.
2460	</li>
2461
2462	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
2463	virtual system (machine) to override the suggestions made by the export() routine.
2464	</li>
2465
2466	<li>Finally, call <link to="#write" /> with a path specification to have the OVF
2467	file written.</li>
2468	</ol>
2469
2470	</desc>
2471
2472	<attribute name="path" type="wstring" readonly="yes">
2473	<desc>Path to the main file of the OVF appliance, which is either the <tt>.ovf</tt> or

2716	<desc>Returns information about the virtual system as arrays of instruction items. In each array, the
2717	items with the same indices correspond and jointly represent an import instruction for VirtualBox.
2718
2719	The list below identifies the value sets that are possible depending on the
2720	<link to="VirtualSystemDescriptionType" /> enum value in the array item in @a aTypes[]. In each case,
2721	the array item with the same index in @a aOvfValues[] will contain the original value as contained
2722	in the OVF file (just for informational purposes), and the corresponding item in @a aVBoxValues[]
2723	will contain a suggested value to be used for VirtualBox. Depending on the description type,
2724	the @a aExtraConfigValues[] array item may also be used.
2725
2726	<ul>
2727	<li>
2728	"OS": the guest operating system type. There must be exactly one such array item on import. The
2729	corresponding item in @a aVBoxValues[] contains the suggested guest operating system for VirtualBox.
2730	This will be one of the values listed in <link to="IVirtualBox::guestOSTypes" />. The corresponding
2731	item in @a aOvfValues[] will contain a numerical value that described the operating system in the OVF.
2732	</li>
2733	<li>
2734	"Name": the name to give to the new virtual machine. There can be at most one such array item;
2735	if none is present on import, then an automatic name will be created from the operating system
2736	type. The correponding item im @a aOvfValues[] will contain the suggested virtual machine name
2737	from the OVF file, and @a aVBoxValues[] will contain a suggestion for a unique VirtualBox
2738	<link to="IMachine" /> name that does not exist yet.
2739	</li>
2740	<li>
2741	"Description": an arbitrary description.
2742	</li>
2743	<li>
2744	"License": the EULA section from the OVF, if present. It is the responsibility of the calling
2745	code to display such a license for agreement; the Main API does not enforce any such policy.
2746	</li>
2747	<li>
2748	Miscellaneous: reserved for future use.
2749	</li>
2750	<li>
2751	"CPU": the number of CPUs. There can be at most one such item, which will presently be ignored.
2752	</li>
2753	<li>
2754	"Memory": the amount of guest RAM, in bytes. There can be at most one such array item; if none
2755	is present on import, then VirtualBox will set a meaningful default based on the operating system
2756	type.
2757	</li>
2758	<li>
2759	"HardDiskControllerIDE": an IDE hard disk controller. There can be at most two such items.
2760	An optional value in @a aOvfValues[] and @a aVBoxValues[] can be "PIIX3" or "PIIX4" to specify
2761	the type of IDE controller; this corresponds to the ResourceSubType element which VirtualBox
2762	writes into the OVF.
2763	The matching item in the @a aRefs[] array will contain an integer that items of the "Harddisk"
2764	type can use to specify which hard disk controller a virtual disk should be connected to.
2765	Note that in OVF, an IDE controller has two channels, corresponding to "master" and "slave"
2766	in traditional terminology, whereas the IDE storage controller that VirtualBox supports in
2767	its virtual machines supports four channels (primary master, primary slave, secondary master,
2768	secondary slave) and thus maps to two IDE controllers in the OVF sense.
2769	</li>
2770	<li>
2771	"HardDiskControllerSATA": an SATA hard disk controller. There can be at most one such item. This
2772	has no value in @a aOvfValues[] or @a aVBoxValues[].
2773	The matching item in the @a aRefs[] array will be used as with IDE controllers (see above).
2774	</li>
2775	<li>
2776	"HardDiskControllerSCSI": a SCSI hard disk controller. There can be at most one such item.
2777	The items in @a aOvfValues[] and @a aVBoxValues[] will either be "LsiLogic", "BusLogic" or
2778	"LsiLogicSas". (Note that in OVF, the LsiLogicSas controller is treated as a SCSI controller
2779	whereas VirtualBox considers it a class of storage controllers of its own; see
2780	<link to="StorageControllerType" />).
2781	The matching item in the @a aRefs[] array will be used as with IDE controllers (see above).
2782	</li>
2783	<li>
2784	"HardDiskImage": a virtual hard disk, most probably as a reference to an image file. There can be an
2785	arbitrary number of these items, one for each virtual disk image that accompanies the OVF.
2786
2787	The array item in @a aOvfValues[] will contain the file specification from the OVF file (without
2788	a path since the image file should be in the same location as the OVF file itself), whereas the
2789	item in @a aVBoxValues[] will contain a qualified path specification to where VirtualBox uses the
2790	hard disk image. This means that on import the image will be copied and converted from the
2791	"ovf" location to the "vbox" location; on export, this will be handled the other way round.
2792
2793	The matching item in the @a aExtraConfigValues[] array must contain a string of the following
2794	format: "controller=<index>;channel=<c>"
2795	In this string, <index> must be an integer specifying the hard disk controller to connect
2796	the image to. That number must be the index of an array item with one of the hard disk controller
2797	types (HardDiskControllerSCSI, HardDiskControllerSATA, HardDiskControllerIDE).
2798	In addition, <c> must specify the channel to use on that controller. For IDE controllers,
2799	this can be 0 or 1 for master or slave, respectively. For compatibility with VirtualBox versions
2800	before 3.2, the values 2 and 3 (for secondary master and secondary slave) are also supported, but
2801	no longer exported. For SATA and SCSI controllers, the channel can range from 0-29.
2802	</li>
2803	<li>
2804	"CDROM": a virtual CD-ROM drive. The matching item in @a aExtraConfigValue[] contains the same
2805	attachment information as with "HardDiskImage" items.
2806	</li>
2807	<li>
2808	"CDROM": a virtual floppy drive. The matching item in @a aExtraConfigValue[] contains the same
2809	attachment information as with "HardDiskImage" items.
2810	</li>
2811	<li>
2812	"NetworkAdapter": a network adapter. The array item in @a aVBoxValues[] will specify the hardware
2813	for the network adapter, whereas the array item in @a aExtraConfigValues[] will have a string
2814	of the "type=<X>" format, where <X> must be either "NAT" or "Bridged".
2815	</li>
2816	<li>
2817	"USBController": a USB controller. There can be at most one such item. If and only if such an
2818	item ispresent, USB support will be enabled for the new virtual machine.
2819	</li>
2820	<li>
2821	"SoundCard": a sound card. There can be at most one such item. If and only if such an item is
2822	present, sound support will be enabled for the new virtual machine. Note that the virtual
2823	machine in VirtualBox will always be presented with the standard VirtualBox soundcard, which
2824	may be different from the virtual soundcard expected by the appliance.

3438	<desc>
3439	The IMachine interface represents a virtual machine, or guest, created
3440	in VirtualBox.
3441
3442	This interface is used in two contexts. First of all, a collection of
3443	objects implementing this interface is stored in the
3444	<link to="IVirtualBox::machines"/> attribute which lists all the virtual
3445	machines that are currently registered with this VirtualBox
3446	installation. Also, once a session has been opened for the given virtual
3447	machine (e.g. the virtual machine is running), the machine object
3448	associated with the open session can be queried from the session object;
3449	see <link to="ISession"/> for details.
3450
3451	The main role of this interface is to expose the settings of the virtual
3452	machine and provide methods to change various aspects of the virtual
3453	machine's configuration. For machine objects stored in the
3454	<link to="IVirtualBox::machines"/> collection, all attributes are
3455	read-only unless explicitly stated otherwise in individual attribute
3456	and method descriptions.
3457
3458	In order to change a machine setting, a session for this machine must be
3459	opened using one of the <link to="IMachine::lockMachine" /> or
3460	<link to="IMachine::launchVMProcess"/> methods. After the
3461	machine has been successfully locked for a session, a mutable machine object
3462	needs to be queried from the session object and then the desired settings
3463	changes can be applied to the returned object using IMachine attributes and
3464	methods. See the <link to="ISession"/> interface description for more
3465	information about sessions.
3466
3467	Note that IMachine does not provide methods to control virtual machine
3468	execution (such as start the machine, or power it down) -- these methods
3469	are grouped in a separate interface called <link to="IConsole" />.

3476	</attribute>
3477
3478	<attribute name="accessible" type="boolean" readonly="yes">
3479	<desc>
3480	Whether this virtual machine is currently accessible or not.
3481
3482	A machine is always deemed accessible unless it is registered <i>and</i>
3483	its settings file cannot be read or parsed (either because the file itself
3484	is unavailable or has invalid XML contents).
3485
3486	Every time this property is read, the accessibility state of
3487	this machine is re-evaluated. If the returned value is @c false,
3488	the <link to="#accessError"/> property may be used to get the
3489	detailed error information describing the reason of
3490	inaccessibility, including XML error messages.
3491
3492	When the machine is inaccessible, only the following properties
3493	can be used on it:
3494	<ul>
3495	<li><link to="#parent"/></li>
3496	<li><link to="#id"/></li>
3497	<li><link to="#settingsFilePath"/></li>
3498	<li><link to="#accessible"/></li>
3499	<li><link to="#accessError"/></li>
3500	</ul>
3501
3502	An attempt to access any other property or method will return
3503	an error.
3504
3505	The only possible action you can perform on an inaccessible
3506	machine is to unregister it using the
3507	<link to="IMachine::unregister"/> call (or, to check
3508	for the accessibility state once more by querying this
3509	property).
3510
3511	<note>
3512	In the current implementation, once this property returns
3513	@c true, the machine will never become inaccessible
3514	later, even if its settings file cannot be successfully
3515	read/written any more (at least, until the VirtualBox
3516	server is restarted). This limitation may be removed in
3517	future releases.

3526
3527	Reading this property is only valid after the last call to
3528	<link to="#accessible"/> returned @c false (i.e. the
3529	machine is currently unaccessible). Otherwise, a @c null
3530	IVirtualBoxErrorInfo object will be returned.

3538	Besides being used for human-readable identification purposes
3539	everywhere in VirtualBox, the virtual machine name is also used
3540	as a name of the machine's settings file and as a name of the
3541	subdirectory this settings file resides in. Thus, every time you
3542	change the value of this property, the settings file will be
3543	renamed once you call <link to="#saveSettings"/> to confirm the

4027	<desc>
4028	Locks the machine for the given session to enable the caller
4029	to make changes to the machine or start the VM or control
4030	VM execution.
4031
4032	There are two ways to lock a machine for such uses:
4033
4034	<ul>
4035	<li>If you want to make changes to the machine settings,
4036	you must obtain an exclusive write lock on the machine
4037	by setting @a lockType to @c Write.
4038
4039	This will only succeed if no other process has locked
4040	the machine to prevent conflicting changes. Only after
4041	an exclusive write lock has been obtained using this method, one
4042	can change all VM settings or execute the VM in the process
4043	space of the session object. (Note that the latter is only of
4044	interest if you actually want to write a new front-end for
4045	virtual machines; but this API gets called internally by
4046	the existing front-ends such as VBoxHeadless and the VirtualBox
4047	GUI to acquire a write lock on the machine that they are running.)
4048
4049	On success, write-locking the machine for a session creates
4050	a second copy of the IMachine object. It is this second object
4051	upon which changes can be made; in VirtualBox terminology, the
4052	second copy is "mutable". It is only this second, mutable machine
4053	object upon which you can call methods that change the
4054	machine state. After having called this method, you can
4055	obtain this second, mutable machine object using the
4056	<link to="ISession::machine" /> attribute.
4057	</li>
4058	<li>If you only want to check the machine state or control
4059	machine execution without actually changing machine
4060	settings (e.g. to get access to VM statistics or take
4061	a snapshot or save the machine state), then set the
4062	@a lockType argument to @c Shared.
4063
4064	If no other session has obtained a lock, you will obtain an
4065	exclusive write lock as described above. However, if another
4066	session has already obtained such a lock, then a link to that
4067	existing session will be established which allows you
4068	to control that existing session.
4069
4070	To find out which type of lock was obtained, you can
4071	inspect <link to="ISession::type" />, which will have been
4072	set to either @c WriteLock or @c Shared.
4073	</li>
4074	</ul>
4075
4076	In either case, you can get access to the <link to="IConsole" />
4077	object which controls VM execution.
4078
4079	Also in all of the above cases, one must always call
4080	<link to="ISession::unlockMachine" /> to release the lock on the machine, or
4081	the machine's state will eventually be set to "Aborted".
4082
4083	To change settings on a machine, the following sequence is typically
4084	performed:
4085
4086	<ol>
4087	<li>Call this method to obtain an exclusive write lock for the current session.</li>
4088
4089	<li>Obtain a mutable IMachine object from <link to="ISession::machine" />.</li>
4090
4091	<li>Change the settings of the machine by invoking IMachine methods.</li>
4092
4093	<li>Call <link to="IMachine::saveSettings" />.</li>
4094

4124
4125	<method name="launchVMProcess">
4126	<desc>
4127	Spawns a new process that will execute the virtual machine and obtains a shared
4128	lock on the machine for the calling session.
4129
4130	If launching the VM succeeds, the new VM process will create its own session
4131	and write-lock the machine for it, preventing conflicting changes from other
4132	processes. If the machine is already locked (because it is already running or
4133	because another session has a write lock), launching the VM process will therefore
4134	fail. Reversely, future attempts to obtain a write lock will also fail while the
4135	machine is running.
4136
4137	The caller's session object remains separate from the session opened by the new
4138	VM process. It receives its own <link to="IConsole" /> object which can be used
4139	to control machine execution, but it cannot be used to change all VM settings
4140	which would be available after a <link to="#lockMachine" /> call.
4141
4142	The caller must eventually release the session's shared lock by calling
4143	<link to="ISession::unlockMachine" /> on the local session object once this call
4144	has returned. However, the session's state (see <link to="ISession::state" />)
4145	will not return to "Unlocked" until the remote session has also unlocked
4146	the machine (i.e. the machine has stopped running).
4147
4148	Lauching a VM process can take some time (a new VM is started in a new process,
4149	for which memory and other resources need to be set up). Because of this,
4150	an <link to="IProgress" /> object is returned to allow the caller to wait
4151	for this asynchronous operation to be completed. Until then, the caller's
4152	session object remains in the "Unlocked" state, and its <link to="ISession::machine" />
4153	and <link to="ISession::console" /> attributes cannot be accessed.
4154	It is recommended to use <link to="IProgress::waitForCompletion" /> or
4155	similar calls to wait for completion. Completion is signalled when the VM
4156	is powered on. If launching the VM fails, error messages can be queried
4157	via the progress object, if available.
4158
4159	The progress object will have at least 2 sub-operations. The first
4160	operation covers the period up to the new VM process calls powerUp.
4161	The subsequent operations mirror the <link to="IConsole::powerUp"/>
4162	progress object. Because <link to="IConsole::powerUp"/> may require
4163	some extra sub-operations, the <link to="IProgress::operationCount"/>
4164	may change at the completion of operation.
4165
4166	For details on the teleportation progress operation, see
4167	<link to="IConsole::powerUp"/>.
4168
4169	The @a environment argument is a string containing definitions of
4170	environment variables in the following format:
4171	@code
4172	NAME[=VALUE]\n
4173	NAME[=VALUE]\n
4174	...
4175	@endcode
4176	where <tt>\\n</tt> is the new line character. These environment
4177	variables will be appended to the environment of the VirtualBox server
4178	process. If an environment variable exists both in the server process
4179	and in this list, the value from this list takes precedence over the
4180	server's variable. If the value of the environment variable is
4181	omitted, this variable will be removed from the resulting environment.
4182	If the environment string is @c null or empty, the server environment
4183	is inherited by the started process as is.

4301
4302	This method is intended for managing storage devices in general while a
4303	machine is powered off. It can be used to attach and detach fixed
4304	and removeable media. The following kind of media can be attached
4305	to a machine:
4306
4307	<ul>
4308	<li>For fixed and removable media, you can pass in a medium that was
4309	previously opened using <link to="IVirtualBox::openMedium" />.
4310	</li>
4311
4312	<li>Only for storage devices supporting removable media (such as
4313	DVDs and floppies), you can also specify a null pointer to
4314	indicate an empty drive or one of the medium objects listed
4315	in the <link to="IHost::DVDDrives" /> and <link to="IHost::floppyDrives"/>
4316	arrays to indicate a host drive.
4317	For removeable devices, you can also use <link to="IMachine::mountMedium"/>
4318	to change the media while the machine is running.
4319	</li>
4320	</ul>
4321
4322	In a VM's default configuration of virtual machines, the secondary
4323	master of the IDE controller is used for a CD/DVD drive.
4324
4325	After calling this returns successfully, a new instance of
4326	<link to="IMediumAttachment"/> will appear in the machine's list of medium
4327	attachments (see <link to="IMachine::mediumAttachments"/>).
4328
4329	See <link to="IMedium"/> and <link to="IMediumAttachment"/> for more
4330	information about attaching media.

4332	The specified device slot must not have a device attached to it,
4333	or this method will fail.
4334
4335	<note>
4336	You cannot attach a device to a newly created machine until
4337	this machine's settings are saved to disk using
4338	<link to="#saveSettings"/>.
4339	</note>
4340	<note>
4341	If the medium is being attached indirectly, a new differencing medium
4342	will implicitly be created for it and attached instead. If the
4343	changes made to the machine settings (including this indirect
4344	attachment) are later cancelled using <link to="#discardSettings"/>,

5026	This method does not delete any files. It only changes the machine configuration and
5027	the list of registered machines in the VirtualBox object. To delete the files which
5028	belonged to the machine, including the XML file of the machine itself, call
5029	<link to="#delete"/>, optionally with the array of IMedium objects which was returned
5030	from this method.
5031
5032	How thoroughly this method cleans up the machine configuration before unregistering
5033	the machine depends on the @a cleanupMode argument.
5034
5035	<ul>
5036	<li>With "UnregisterOnly", the machine will only be unregistered, but no additional
5037	cleanup will be performed. The call will fail if the machine is in "Saved" state
5038	or has any snapshots or any media attached (see <link to="IMediumAttachment" />.
5039	It is the responsibility of the caller to delete all such configuration in this mode.
5040	In this mode, the API behaves like the former @c IVirtualBox::unregisterMachine() API
5041	which it replaces.</li>
5042	<li>With "DetachAllReturnNone", the call will succeed even if the machine is in "Saved"
5043	state or if it has snapshots or media attached. All media attached to the current machine
5044	state or in snapshots will be detached. No medium objects will be returned; all of the
5045	machine's media will remain open.</li>
5046	<li>With "DetachAllReturnHardDisksOnly", the call will behave like with "DetachAllReturnNone",
5047	except that all the hard disk medium objects which were detached from the machine will
5048	be returned as an array. This allows for quickly passing them to the <link to="#delete" />
5049	API for closing and deletion.</li>
5050	<li>With "Full", the call will behave like with "DetachAllReturnHardDisksOnly", except
5051	that all media will be returned in the array, including removeable media like DVDs and
5052	floppies. This might be useful if the user wants to inspect in detail which media were
5053	attached to the machine. Be careful when passing the media array to <link to="#delete" />
5054	in that case because users will typically want to preserve ISO and RAW image files.</li>
5055	</ul>
5056
5057	This API does not verify whether the media files returned in the array are still
5058	attached to other machines (i.e. shared between several machines). If such a shared
5059	image is passed to <link to="#delete" /> however, closing the image will fail there
5060	and the image will be silently skipped.
5061
5062	A typical implementation will use "DetachAllReturnHardDisksOnly" and then pass the
5063	resulting IMedia array to <link to="#delete"/>. This way, the machine is completely
5064	deleted with all its saved states and hard disk images, but images for removeable
5065	drives (such as ISO and RAW files) will remain on disk.
5066
5067	The call will fail if the machine is currently locked (see <link to="ISession" />).
5068	It implicitly calls <link to="#saveSettings"/> to save all current machine settings
5069	before unregistering it.
5070
5071	After successful method invocation, the <link to="IMachineRegisteredEvent"/> event
5072	is fired.
5073
5074	<note>
5075	If the given machine is inaccessible (see <link to="#accessible"/>), it
5076	will be unregistered and fully uninitialized right afterwards. As a result,
5077	the returned machine object will be unusable and an attempt to call
5078	<b>any</b> method will return the "Object not ready" error.

5099	the same as the one returned from a previous <link to="#unregister" /> call.
5100
5101	This method must only be called on machines which are either write-locked (i.e. on instances
5102	returned by <link to="ISession::machine"/>) or on unregistered machines (i.e. not yet
5103	registered machines created by <link to="IVirtualBox::createMachine"/> or opened by
5104	<link to="IVirtualBox::openMachine"/>, or after having called <link to="#unregister"/>).
5105
5106	The following files will be deleted by this method:
5107	<ul>
5108	<li>If <link to="#unregister" /> had been previously called with a @a cleanupMode
5109	argument other than "UnregisterOnly", this will delete all saved state files that
5110	the machine had in use; possibly one if the machine was in "Saved" state and one
5111	for each online snapshot that the machine had.</li>
5112	<li>On each medium object passed in the @a aMedia array, this will call
5113	<link to="IMedium::close" />. If that succeeds, this will attempt to delete the
5114	medium's storage on disk. Since the close() call will fail if the medium is still
5115	in use, e.g. because it is still attached to a second machine; in that case the
5116	storage will not be deleted.</li>
5117	<li>Finally, the machine's own XML file will be deleted.</li>
5118	</ul>
5119
5120	Since deleting large disk image files can be a time-consuming I/O operation, this
5121	method operates asynchronously and returns an IProgress object to allow the caller
5122	to monitor the progress. There will be one sub-operation for each file that is
5123	being deleted (saved state or medium storage file).
5124
5125	<note>
5126	<link to="#settingsModified"/> will return @c true after this
5127	method successfully returns.

6440
6441	The execution state and settings of the associated machine stored in
6442	the snapshot will be deleted. The contents of all differencing media of
6443	this snapshot will be merged with the contents of their dependent child
6444	media to keep the medium chain valid (in other words, all changes
6445	represented by media being deleted will be propagated to their child
6446	medium). After that, this snapshot's differencing medium will be
6447	deleted. The parent of this snapshot will become a new parent for all
6448	its child snapshots.
6449
6450	If the deleted snapshot is the current one, its parent snapshot will
6451	become a new current snapshot. The current machine state is not directly
6452	affected in this case, except that currently attached differencing
6453	media based on media of the deleted snapshot will be also merged as
6454	described above.
6455
6456	If the deleted snapshot is the first or current snapshot, then the
6457	respective IMachine attributes will be adjusted. Deleting the current
6458	snapshot will also implicitly call <link to="IMachine::saveSettings"/>
6459	to make all current machine settings permanent.
6460
6461	Deleting a snapshot has the following preconditions:
6462
6463	<ul>
6464	<li>Child media of all normal media of the deleted snapshot
6465	must be accessible (see <link to="IMedium::state"/>) for this
6466	operation to succeed. In particular, this means that all virtual
6467	machines, whose media are directly or indirectly based on the
6468	media of deleted snapshot, must be powered off.</li>
6469
6470	<li>You cannot delete the snapshot if a medium attached to it has
6471	more than once child medium (differencing images) because otherwise
6472	merging would be impossible. This might be the case if there is
6473	more than one child snapshot or differencing images were created
6474	for other reason (e.g. implicitly because of multiple machine
6475	attachments).</li>
6476	</ul>
6477
6478
6479	The virtual machine's <link to="IMachine::state">state</link> is
6480	changed to "DeletingSnapshot", "DeletingSnapshotOnline" or
6481	"DeletingSnapshotPaused" while this operation is in progress.
6482
6483	<note>
6484	Merging medium contents can be very time and disk space
6485	consuming, if these media are big in size and have many
6486	children. However, if the snapshot being deleted is the last
6487	(head) snapshot on the branch, the operation will be rather
6488	quick.

7356	List of all medium storage formats supported by this VirtualBox

7358
7359	Keep in mind that the medium format identifier
7360	(<link to="IMediumFormat::id"/>) used in other API calls like
7361	<link to="IVirtualBox::createHardDisk"/> to refer to a particular

7365	"VDI"
7366	"vdi"
7367	"VdI"</pre>
7368	refer to the same medium format.

7370	Note that the virtual medium framework is backend-based, therefore
7371	the list of supported formats depends on what backends are currently

7381	<desc>
7382	Identifier of the default medium format used by VirtualBox.
7383
7384	The medium format set by this attribute is used by VirtualBox
7385	when the medium format was not specified explicitly. One example is
7386	<link to="IVirtualBox::createHardDisk"/> with the empty
7387	format argument. A more complex example is implicit creation of
7388	differencing media when taking a snapshot of a virtual machine:
7389	this operation will try to use a format of the parent medium first
7390	and if this format does not support differencing media the default
7391	format specified by this argument will be used.
7392
7393	The list of supported medium formats may be obtained by the
7394	<link to="#mediumFormats"/> call. Note that the default medium
7395	format must have a capability to create differencing media;
7396	otherwise operations that create media implicitly may fail
7397	unexpectedly.

7399	The initial value of this property is <tt>"VDI"</tt> in the current

7466
7467	As opposed to <link to="ISystemProperties::remoteDisplayAuthLibrary" />,

7469	resource (if it is running). Only for this setting (for the webservice),
7470	setting this value to a literal <tt>"null"</tt> string disables authentication,

7472	no matter what user name and password are supplied.
7473
7474	The initial value of this property is <tt>"VRDPAuth"</tt>,
7475	meaning that the webservice will use the same authentication
7476	library that is used by default for VBoxVRDP (again, see

8025	<desc>
8026	The IProgress interface is used to track and control
8027	asynchronous tasks within VirtualBox.
8028
8029	An instance of this is returned every time VirtualBox starts
8030	an asynchronous task (in other words, a separate thread) which
8031	continues to run after a method call returns. For example,
8032	<link to="IConsole::saveState" />, which saves the state of
8033	a running virtual machine, can take a long time to complete.
8034	To be able to display a progress bar, a user interface such as
8035	the VirtualBox graphical user interface can use the IProgress
8036	object returned by that method.
8037
8038	Note that IProgress is a "read-only" interface in the sense
8039	that only the VirtualBox internals behind the Main API can
8040	create and manipulate progress objects, whereas client code
8041	can only use the IProgress object to monitor a task's
8042	progress and, if <link to="#cancelable" /> is @c true,
8043	cancel the task by calling <link to="#cancel" />.
8044
8045	A task represented by IProgress consists of either one or
8046	several sub-operations that run sequentially, one by one (see
8047	<link to="#operation" /> and <link to="#operationCount" />).
8048	Every operation is identified by a number (starting from 0)
8049	and has a separate description.
8050
8051	You can find the individual percentage of completion of the current
8052	operation in <link to="#operationPercent" /> and the
8053	percentage of completion of the task as a whole
8054	in <link to="#percent" />.
8055
8056	Similarly, you can wait for the completion of a particular
8057	operation via <link to="#waitForOperationCompletion" /> or
8058	for the completion of the whole task via
8059	<link to="#waitForCompletion" />.

8092
8093	Even if a value is returned, the estimate will be unreliable
8094	for low progress values. It will become more reliable as the

8242	wsmap="managed"
8243	>
8244	<desc>
8245	The ISnapshot interface represents a snapshot of the virtual
8246	machine.
8247
8248	Together with the differencing media that are created
8249	when a snapshot is taken, a machine can be brought back to
8250	the exact state it was in when the snapshot was taken.
8251
8252	The ISnapshot interface has no methods, only attributes; snapshots
8253	are controlled through methods of the <link to="IConsole" /> interface
8254	which also manage the media associated with the snapshot.
8255	The following operations exist:
8256
8257	<ul>
8258	<li><link to="IConsole::takeSnapshot"/> creates a new snapshot
8259	by creating new, empty differencing images for the machine's
8260	media and saving the VM settings and (if the VM is running)
8261	the current VM state in the snapshot.
8262
8263	The differencing images will then receive all data written to
8264	the machine's media, while their parent (base) images
8265	remain unmodified after the snapshot has been taken (see
8266	<link to="IMedium" /> for details about differencing images).
8267	This simplifies restoring a machine to the state of a snapshot:
8268	only the differencing images need to be deleted.
8269
8270	The current machine state is not changed by taking a snapshot.
8271	If the machine is running, it will resume execution after the
8272	snapshot has been taken. After calling this,
8273	<link to="IMachine::currentSnapshot" /> is set to the snapshot
8274	just created.
8275	</li>
8276
8277	<li><link to="IConsole::restoreSnapshot"/> resets a machine to
8278	the state of a previous snapshot by deleting the differencing
8279	image of each of the machine's media and setting the machine's
8280	settings and state to the state that was saved in the snapshot (if any).
8281
8282	This destroys the machine's current state. After calling this,
8283	<link to="IMachine::currentSnapshot" /> is set to the snapshot that was
8284	restored.
8285	</li>
8286
8287	<li><link to="IConsole::deleteSnapshot"/> deletes a snapshot
8288	without affecting the current machine state.
8289
8290	This does not change the current machine state, but instead frees the
8291	resources allocated when the snapshot was taken: the settings and machine
8292	state file are deleted (if any), and the snapshot's differencing image for
8293	each of the machine's media gets merged with its parent image.
8294
8295	Neither the current machine state nor other snapshots are affected
8296	by this operation, except that parent media will be modified
8297	to contain the disk data associated with the snapshot being deleted.

8299	When deleting the current snapshot, the <link to="IMachine::currentSnapshot" />

8308	the current VM state is saved in the snapshot (similarly to what happens
8309	when a VM's state is saved). The snapshot is then said to
8310	be <i>online</i> because when restoring it, the VM will be running.
8311
8312	If the machine is saved (<link to="MachineState_Saved"/>), the snapshot

8316	or <link to="MachineState_Aborted"/>), the snapshot is <i>offline</i>;

8583	<desc>
8584	The IMedium interface represents virtual storage for a machine's
8585	hard disks, CD/DVD or floppy drives. It will typically represent
8586	a disk image on the host, for example a VDI or VMDK file representing
8587	a virtual hard disk, or an ISO or RAW file representing virtual
8588	removable media, but can also point to a network location (e.g.
8589	for iSCSI targets).
8590
8591	Instances of IMedium are connected to virtual machines by way of
8592	medium attachments (see <link to="IMediumAttachment" />), which link
8593	the storage medium to a particular device slot of a storage controller
8594	of the virtual machine.
8595	In the VirtualBox API, virtual storage is therefore always represented
8596	by the following chain of object links:
8597
8598	<ul>
8599	<li><link to="IMachine::storageControllers"/> contains an array of
8600	storage controllers (IDE, SATA, SCSI, SAS or a floppy controller;
8601	these are instances of <link to="IStorageController"/>).</li>
8602	<li><link to="IMachine::mediumAttachments"/> contains an array of
8603	medium attachments (instances of <link to="IMediumAttachment"/>),
8604	each containing a storage controller from the above array, a
8605	port/device specification, and an instance of IMedium representing
8606	the medium storage (image file).
8607
8608	For removable media, the storage medium is optional; a medium
8609	attachment with no medium represents a CD/DVD or floppy drive
8610	with no medium inserted. By contrast, hard disk attachments
8611	will always have an IMedium object attached.</li>
8612	<li>Each IMedium in turn points to a storage unit (such as a file
8613	on the host computer or a network resource) that holds actual
8614	data. This location is represented by the <link to="#location"/>
8615	attribute.</li>
8616	</ul>
8617
8618	Existing media are opened using <link to="IVirtualBox::openMedium"/>;
8619	new hard disk media can be created with the VirtualBox API using the
8620	<link to="IVirtualBox::createHardDisk"/> method.
8621
8622	CD/DVD and floppy images (ISO and RAW files) are usually created outside
8623	VirtualBox, e.g. by storing a copy of the real medium of the corresponding
8624	type in a regular file.
8625
8626	Only for CD/DVDs and floppies, an IMedium instance can also represent a host
8627	drive; in that case the <link to="#id" /> attribute contains the UUID of
8628	one of the drives in <link to="IHost::DVDDrives" /> or <link to="IHost::floppyDrives" />.
8629
8630	<h3>Known media</h3>
8631
8632	When an existing medium is opened for the first time, it is automatically
8633	remembered by the given VirtualBox installation or, in other words, becomes
8634	a <i>known medium</i>. Known media are stored in the media
8635	registry transparently maintained by VirtualBox and stored in settings
8636	files so that this registry is preserved when VirtualBox is not running.
8637
8638	Newly created virtual media are remembered only when the associated
8639	storage unit is actually created.
8640
8641	All known media can be enumerated using
8642	<link to="IVirtualBox::hardDisks"/>,
8643	<link to="IVirtualBox::DVDImages"/> and
8644	<link to="IVirtualBox::floppyImages"/> attributes. Individual media can be
8645	quickly found using the <link to="IVirtualBox::findMedium"/> method.
8646
8647	Only known media can be attached to virtual machines.
8648
8649	Removing known media from the media registry is performed when the given
8650	medium is closed using the <link to="#close"/> method or when its
8651	associated storage unit is deleted.
8652
8653	<h3>Accessibility checks</h3>
8654
8655	VirtualBox defers media accessibility checks until the <link to="#refreshState" />
8656	method is called explicitly on a medium. This is done to make the VirtualBox object
8657	ready for serving requests as fast as possible and let the end-user
8658	application decide if it needs to check media accessibility right away or not.
8659
8660	As a result, when VirtualBox starts up (e.g. the VirtualBox
8661	object gets created for the first time), all known media are in the
8662	"Inaccessible" state, but the value of the <link to="#lastAccessError"/>
8663	attribute is an empty string because no actual accessibility check has
8664	been made yet.
8665
8666	After calling <link to="#refreshState" />, a medium is considered
8667	<i>accessible</i> if its storage unit can be read. In that case, the
8668	<link to="#state"/> attribute has a value of "Created". If the storage
8669	unit cannot be read (for example, because it is located on a disconnected
8670	network resource, or was accidentally deleted outside VirtualBox),
8671	the medium is considered <i>inaccessible</i>, which is indicated by the
8672	"Inaccessible" state. The exact reason why the medium is inaccessible can be
8673	obtained by reading the <link to="#lastAccessError"/> attribute.
8674
8675	<h3>Medium types</h3>
8676
8677	There are four types of medium behavior (see <link to="MediumType" />):
8678	"normal", "immutable", "writethrough" and "shareable", represented by the
8679	<link to="#type"/> attribute. The type of the medium defines how the
8680	medium is attached to a virtual machine and what happens when a
8681	<link to="ISnapshot">snapshot</link> of the virtual machine with the
8682	attached medium is taken. At the moment DVD and floppy media are always
8683	of type "writethrough".
8684
8685	All media can be also divided in two groups: <i>base</i> media and
8686	<i>differencing</i> media. A base medium contains all sectors of the
8687	medium data in its own storage and therefore can be used independently.
8688	In contrast, a differencing mediun is a "delta" to some other medium and
8689	contains only those sectors which differ from that other medium, which is
8690	then called a <i>parent</i>. The differencing medium is said to be
8691	<i>linked to</i> that parent. The parent may be itself a differencing
8692	medium, thus forming a chain of linked media. The last element in that
8693	chain must always be a base medium. Note that several differencing
8694	media may be linked to the same parent medium.
8695
8696	Differencing media can be distinguished from base media by querying the
8697	<link to="#parent"/> attribute: base media do not have parents they would
8698	depend on, so the value of this attribute is always @c null for them.
8699	Using this attribute, it is possible to walk up the medium tree (from the
8700	child medium to its parent). It is also possible to walk down the tree
8701	using the <link to="#children"/> attribute.
8702
8703	Note that the type of all differencing media is "normal"; all other
8704	values are meaningless for them. Base media may be of any type.
8705
8706	<h3>Creating hard disks</h3>
8707
8708	New base hard disks are created using
8709	<link to="IVirtualBox::createHardDisk"/>. Existing hard disks are
8710	opened using <link to="IVirtualBox::openMedium"/>. Differencing hard
8711	disks are usually implicitly created by VirtualBox when needed but may
8712	also be created explicitly using <link to="#createDiffStorage"/>.
8713
8714	After the hard disk is successfully created (including the storage unit)
8715	or opened, it becomes a known hard disk (remembered in the internal media
8716	registry). Known hard disks can be attached to a virtual machine, accessed
8717	through <link to="IVirtualBox::findMedium"/> or enumerated using the
8718	<link to="IVirtualBox::hardDisks"/> array (only for base hard disks).
8719
8720	The following methods, besides <link to="IMedium::close"/>,
8721	automatically remove the hard disk from the media registry:
8722	<ul>
8723	<li><link to="#deleteStorage"/></li>
8724	<li><link to="#mergeTo"/></li>
8725	</ul>
8726
8727	If the storage unit of the hard disk is a regular file in the host's
8728	file system then the rules stated in the description of the
8729	<link to="IMedium::location"/> attribute apply when setting its value. In
8730	addition, a plain file name without any path may be given, in which case
8731	the <link to="ISystemProperties::defaultHardDiskFolder"> default hard disk
8732	folder</link> will be prepended to it.
8733
8734	<h4>Automatic composition of the file name part</h4>
8735
8736	Another extension to the <link to="IMedium::location"/> attribute is that
8737	there is a possibility to cause VirtualBox to compose a unique value for
8738	the file name part of the location using the UUID of the hard disk. This
8739	applies only to hard disks in <link to="MediumState_NotCreated"/> state,
8740	e.g. before the storage unit is created, and works as follows. You set the
8741	value of the <link to="IMedium::location"/> attribute to a location
8742	specification which only contains the path specification but not the file
8743	name part and ends with either a forward slash or a backslash character.
8744	In response, VirtualBox will generate a new UUID for the hard disk and
8745	compose the file name using the following pattern:
8746	<pre>
8747	<path>/{<uuid>}.<ext>
8748	</pre>
8749	where <tt><path></tt> is the supplied path specification,
8750	<tt><uuid></tt> is the newly generated UUID and <tt><ext></tt>
8751	is the default extension for the storage format of this hard disk. After
8752	that, you may call any of the methods that create a new hard disk storage
8753	unit and they will use the generated UUID and file name.
8754
8755	<h3>Attaching Hard Disks</h3>
8756
8757	Hard disks are attached to virtual machines using the
8758	<link to="IMachine::attachDevice"/> method and detached using the
8759	<link to="IMachine::detachDevice"/> method. Depending on their
8760	<link to="#type"/>, hard disks are attached either
8761	<i>directly</i> or <i>indirectly</i>.
8762
8763	When a hard disk is being attached directly, it is associated with the
8764	virtual machine and used for hard disk operations when the machine is
8765	running. When a hard disk is being attached indirectly, a new differencing
8766	hard disk linked to it is implicitly created and this differencing hard
8767	disk is associated with the machine and used for hard disk operations.
8768	This also means that if <link to="IMachine::attachDevice"/> performs
8769	a direct attachment then the same hard disk will be returned in response
8770	to the subsequent <link to="IMachine::getMedium"/> call; however if
8771	an indirect attachment is performed then
8772	<link to="IMachine::getMedium"/> will return the implicitly created
8773	differencing hard disk, not the original one passed to <link
8774	to="IMachine::attachDevice"/>. In detail:
8775
8776	<ul>
8777	<li><b>Normal base</b> hard disks that do not have children (i.e.
8778	differencing hard disks linked to them) and that are not already
8779	attached to virtual machines in snapshots are attached <b>directly</b>.
8780	Otherwise, they are attached <b>indirectly</b> because having
8781	dependent children or being part of the snapshot makes it impossible
8782	to modify hard disk contents without breaking the integrity of the
8783	dependent party. The <link to="#readOnly"/> attribute allows to
8784	quickly determine the kind of the attachment for the given hard
8785	disk. Note that if a normal base hard disk is to be indirectly
8786	attached to a virtual machine with snapshots then a special
8787	procedure called <i>smart attachment</i> is performed (see below).</li>
8788	<li><b>Normal differencing</b> hard disks are like normal base hard disks:
8789	they are attached <b>directly</b> if they do not have children and are
8790	not attached to virtual machines in snapshots, and <b>indirectly</b>
8791	otherwise. Note that the smart attachment procedure is never performed
8792	for differencing hard disks.</li>
8793	<li><b>Immutable</b> hard disks are always attached <b>indirectly</b> because
8794	they are designed to be non-writable. If an immutable hard disk is
8795	attached to a virtual machine with snapshots then a special
8796	procedure called smart attachment is performed (see below).</li>
8797	<li><b>Writethrough</b> hard disks are always attached <b>directly</b>,
8798	also as designed. This also means that writethrough hard disks cannot
8799	have other hard disks linked to them at all.</li>
8800	<li><b>Shareable</b> hard disks are always attached <b>directly</b>,
8801	also as designed. This also means that shareable hard disks cannot
8802	have other hard disks linked to them at all. They behave almost
8803	like writethrough hard disks, except that shareable hard disks can
8804	be attached to several virtual machines which are running, allowing
8805	concurrent accesses. You need special cluster software running in
8806	the virtual machines to make use of such disks.</li>
8807	</ul>
8808
8809	Note that the same hard disk, regardless of its type, may be attached to
8810	more than one virtual machine at a time. In this case, the machine that is
8811	started first gains exclusive access to the hard disk and attempts to
8812	start other machines having this hard disk attached will fail until the
8813	first machine is powered down.
8814
8815	Detaching hard disks is performed in a <i>deferred</i> fashion. This means
8816	that the given hard disk remains associated with the given machine after a
8817	successful <link to="IMachine::detachDevice"/> call until
8818	<link to="IMachine::saveSettings"/> is called to save all changes to
8819	machine settings to disk. This deferring is necessary to guarantee that
8820	the hard disk configuration may be restored at any time by a call to
8821	<link to="IMachine::discardSettings"/> before the settings
8822	are saved (committed).
8823
8824	Note that if <link to="IMachine::discardSettings"/> is called after
8825	indirectly attaching some hard disks to the machine but before a call to
8826	<link to="IMachine::saveSettings"/> is made, it will implicitly delete
8827	all differencing hard disks implicitly created by
8828	<link to="IMachine::attachDevice"/> for these indirect attachments.
8829	Such implicitly created hard disks will also be immediately deleted when
8830	detached explicitly using the <link to="IMachine::detachDevice"/>
8831	call if it is made before <link to="IMachine::saveSettings"/>. This
8832	implicit deletion is safe because newly created differencing hard
8833	disks do not contain any user data.
8834
8835	However, keep in mind that detaching differencing hard disks that were
8836	implicitly created by <link to="IMachine::attachDevice"/>
8837	before the last <link to="IMachine::saveSettings"/> call will
8838	<b>not</b> implicitly delete them as they may already contain some data
8839	(for example, as a result of virtual machine execution). If these hard
8840	disks are no more necessary, the caller can always delete them explicitly
8841	using <link to="#deleteStorage"/> after they are actually de-associated
8842	from this machine by the <link to="IMachine::saveSettings"/> call.
8843
8844	<h3>Smart Attachment</h3>
8845
8846	When normal base or immutable hard disks are indirectly attached to a
8847	virtual machine then some additional steps are performed to make sure the
8848	virtual machine will have the most recent "view" of the hard disk being
8849	attached. These steps include walking through the machine's snapshots
8850	starting from the current one and going through ancestors up to the first
8851	snapshot. Hard disks attached to the virtual machine in all
8852	of the encountered snapshots are checked whether they are descendants of
8853	the given normal base or immutable hard disk. The first found child (which
8854	is the differencing hard disk) will be used instead of the normal base or
8855	immutable hard disk as a parent for creating a new differencing hard disk
8856	that will be actually attached to the machine. And only if no descendants
8857	are found or if the virtual machine does not have any snapshots then the
8858	normal base or immutable hard disk will be used itself as a parent for
8859	this differencing hard disk.
8860
8861	It is easier to explain what smart attachment does using the
8862	following example:
8863	<pre>
8864	BEFORE attaching B.vdi: AFTER attaching B.vdi:
8865
8866	Snapshot 1 (B.vdi) Snapshot 1 (B.vdi)
8867	Snapshot 2 (D1->B.vdi) Snapshot 2 (D1->B.vdi)
8868	Snapshot 3 (D2->D1.vdi) Snapshot 3 (D2->D1.vdi)
8869	Snapshot 4 (none) Snapshot 4 (none)
8870	CurState (none) CurState (D3->D2.vdi)
8871
8872	NOT
8873	...
8874	CurState (D3->B.vdi)
8875	</pre>
8876	The first column is the virtual machine configuration before the base hard
8877	disk <tt>B.vdi</tt> is attached, the second column shows the machine after
8878	this hard disk is attached. Constructs like <tt>D1->B.vdi</tt> and similar
8879	mean that the hard disk that is actually attached to the machine is a
8880	differencing hard disk, <tt>D1.vdi</tt>, which is linked to (based on)
8881	another hard disk, <tt>B.vdi</tt>.
8882
8883	As we can see from the example, the hard disk <tt>B.vdi</tt> was detached
8884	from the machine before taking Snapshot 4. Later, after Snapshot 4 was
8885	taken, the user decides to attach <tt>B.vdi</tt> again. <tt>B.vdi</tt> has
8886	dependent child hard disks (<tt>D1.vdi</tt>, <tt>D2.vdi</tt>), therefore
8887	it cannot be attached directly and needs an indirect attachment (i.e.
8888	implicit creation of a new differencing hard disk). Due to the smart
8889	attachment procedure, the new differencing hard disk
8890	(<tt>D3.vdi</tt>) will be based on <tt>D2.vdi</tt>, not on
8891	<tt>B.vdi</tt> itself, since <tt>D2.vdi</tt> is the most recent view of
8892	<tt>B.vdi</tt> existing for this snapshot branch of the given virtual
8893	machine.
8894
8895	Note that if there is more than one descendant hard disk of the given base
8896	hard disk found in a snapshot, and there is an exact device, channel and
8897	bus match, then this exact match will be used. Otherwise, the youngest
8898	descendant will be picked up.
8899
8900	There is one more important aspect of the smart attachment procedure which
8901	is not related to snapshots at all. Before walking through the snapshots
8902	as described above, the backup copy of the current list of hard disk
8903	attachment is searched for descendants. This backup copy is created when
8904	the hard disk configuration is changed for the first time after the last
8905	<link to="IMachine::saveSettings"/> call and used by
8906	<link to="IMachine::discardSettings"/> to undo the recent hard disk
8907	changes. When such a descendant is found in this backup copy, it will be
8908	simply re-attached back, without creating a new differencing hard disk for
8909	it. This optimization is necessary to make it possible to re-attach the
8910	base or immutable hard disk to a different bus, channel or device slot
8911	without losing the contents of the differencing hard disk actually
8912	attached to the machine in place of it.

9263	<desc>
9264	If the current medium state (see <link to="MediumState"/>) is one of
9265	"Created", "Inaccessible" or "LockedRead", then this performs an
9266	accessibility check on the medium and sets the value of the <link to="#state"/>
9267	attribute accordingly; that value is also returned for convenience.
9268
9269	For all other state values, this does not perform a refresh but returns
9270	the state only.
9271
9272	The refresh, if performed, may take a long time (several seconds or even
9273	minutes, depending on the storage unit location and format) because it performs an
9274	accessibility check of the storage unit. This check may cause a significant
9275	delay if the storage unit of the given medium is, for example, a file located
9276	on a network share which is not currently accessible due to connectivity
9277	problems. In that case, the call will not return until a timeout
9278	interval defined by the host OS for this operation expires. For this reason,
9279	it is recommended to never read this attribute on the main UI thread to avoid
9280	making the UI unresponsive.
9281
9282	If the last known state of the medium is "Created" and the accessibility
9283	check fails, then the state would be set to "Inaccessible", and
9284	<link to="#lastAccessError"/> may be used to get more details about the
9285	failure. If the state of the medium is "LockedRead", then it remains the
9286	same, and a non-empty value of <link to="#lastAccessError"/> will
9287	indicate a failed accessibility check in this case.

9327	<method name="lockRead">
9328	<desc>
9329	Locks this medium for reading.
9330
9331	A read lock is shared: many clients can simultaneously lock the
9332	same medium for reading unless it is already locked for writing (see
9333	<link to="#lockWrite"/>) in which case an error is returned.
9334
9335	When the medium is locked for reading, it cannot be modified
9336	from within VirtualBox. This means that any method that changes
9337	the properties of this medium or contents of the storage unit
9338	will return an error (unless explicitly stated otherwise). That
9339	includes an attempt to start a virtual machine that wants to
9340	write to the the medium.
9341
9342	When the virtual machine is started up, it locks for reading all
9343	media it uses in read-only mode. If some medium cannot be locked
9344	for reading, the startup procedure will fail.
9345	A medium is typically locked for reading while it is used by a running
9346	virtual machine but has a depending differencing image that receives
9347	the actual write operations. This way one base medium can have
9348	multiple child differencing images which can be written to
9349	simultaneously. Read-only media such as DVD and floppy images are
9350	also locked for reading only (so they can be in use by multiple
9351	machines simultaneously).
9352
9353	A medium is also locked for reading when it is the source of a
9354	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9355
9356	The medium locked for reading must be unlocked using the <link
9357	to="#unlockRead"/> method. Calls to <link to="#lockRead"/>
9358	can be nested and must be followed by the same number of paired
9359	<link to="#unlockRead"/> calls.
9360
9361	This method sets the medium state (see <link to="#state"/>) to
9362	"LockedRead" on success. The medium's previous state must be
9363	one of "Created", "Inaccessible" or "LockedRead".
9364
9365	Locking an inaccessible medium is not an error; this method performs
9366	a logical lock that prevents modifications of this medium through
9367	the VirtualBox API, not a physical file-system lock of the underlying
9368	storage unit.

9407	<method name="lockWrite">
9408	<desc>
9409	Locks this medium for writing.
9410
9411	A write lock, as opposed to <link to="#lockRead"/>, is
9412	exclusive: there may be only one client holding a write lock,
9413	and there may be no read locks while the write lock is held.
9414	As a result, read-locking fails if a write lock is held, and
9415	write-locking fails if either a read or another write lock is held.
9416
9417	When a medium is locked for writing, it cannot be modified
9418	from within VirtualBox, and it is not guaranteed that the values
9419	of its properties are up-to-date. Any method that changes the
9420	properties of this medium or contents of the storage unit will
9421	return an error (unless explicitly stated otherwise).
9422
9423	When a virtual machine is started up, it locks for writing all
9424	media it uses to write data to. If any medium could not be locked
9425	for writing, the startup procedure will fail. If a medium has
9426	differencing images, then while the machine is running, only
9427	the last ("leaf") differencing image is locked for writing,
9428	whereas its parents are locked for reading only.
9429
9430	A medium is also locked for writing when it is the target of a
9431	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9432
9433	The medium locked for writing must be unlocked using the <link
9434	to="#unlockWrite"/> method. Write locks <i>cannot</i> be nested.
9435
9436	This method sets the medium state (see <link to="#state"/>) to

9770	Here, calling this method on the <tt>Base</tt> medium object with
9771	<tt>Diff_2</tt> as an argument will be a forward merge; calling it on
9772	<tt>Diff_2</tt> with <tt>Base</tt> as an argument will be a backward
9773	merge. Note that in both cases the contents of the resulting medium
9774	will be the same, the only difference is the medium object that takes
9775	the result of the merge operation. In case of the forward merge in the
9776	above example, the result will be written to <tt>Diff_2</tt>; in case of
9777	the backward merge, the result will be written to <tt>Base</tt>. In
9778	other words, the result of the operation is always stored in the target
9779	medium.
9780
9781	Upon successful operation completion, the storage units of all media in
9782	the chain between this (source) medium and the target medium, including
9783	the source medium itself, will be automatically deleted and the
9784	relevant medium objects (including this medium) will become
9785	uninitialized. This means that any attempt to call any of
9786	their methods or attributes will fail with the
9787	<tt>"Object not ready" (E_ACCESSDENIED)</tt> error. Applied to the above
9788	example, the forward merge of <tt>Base</tt> to <tt>Diff_2</tt> will
9789	delete and uninitialize both <tt>Base</tt> and <tt>Diff_1</tt> media.
9790	Note that <tt>Diff_2</tt> in this case will become a base medium
9791	itself since it will no longer be based on any other medium.
9792
9793	Considering the above, all of the following conditions must be met in
9794	order for the merge operation to succeed:
9795	<ul>
9796	<li>
9797	Neither this (source) medium nor any intermediate
9798	differencing medium in the chain between it and the target
9799	medium is attached to any virtual machine.
9800	</li>
9801	<li>
9802	Neither the source medium nor the target medium is an
9803	<link to="MediumType_Immutable"/> medium.
9804	</li>
9805	<li>
9806	The part of the medium tree from the source medium to the
9807	target medium is a linear chain, i.e. all medium in this
9808	chain have exactly one child which is the next medium in this
9809	chain. The only exception from this rule is the target medium in
9810	the forward merge operation; it is allowed to have any number of
9811	child media because the merge operation will not change its
9812	logical contents (as it is seen by the guest OS or by children).
9813	</li>
9814	<li>
9815	None of the involved media are in
9816	<link to="MediumState_LockedRead"/> or
9817	<link to="MediumState_LockedWrite"/> state.
9818	</li>
9819	</ul>
9820
9821	<note>
9822	This (source) medium and all intermediates will be placed to <link
9823	to="MediumState_Deleting"/> state and the target medium will be
9824	placed to <link to="MediumState_LockedWrite"/> state and for the
9825	duration of this operation.

9846	big enough to hold the data or else the copy will be partial). Upon
9847	successful completion, the cloned medium will contain exactly the
9848	same sector data as the medium being cloned, except that in the
9849	first case a new UUID for the clone will be randomly generated, and in
9850	the second case the UUID will remain unchanged.
9851
9852	The @a parent argument defines which medium will be the parent
9853	of the clone. Passing a @c null reference indicates that the clone will
9854	be a base image, i.e. completely independent. It is possible to specify
9855	an arbitrary medium for this parameter, including the parent of the
9856	medium which is being cloned. Even cloning to a child of the source
9857	medium is possible. Note that when cloning to an existing image, the

9859
9860	After the returned progress object reports that the operation is

9920
9921	Resizing usually needs additional disk space, and possibly also

10585
10586	There are two modes of working with the video buffer of the virtual
10587	machine. The <i>indirect</i> mode implies that the IFramebuffer
10588	implementation allocates a memory buffer for the requested display mode
10589	and provides it to the virtual machine. In <i>direct</i> mode, the
10590	IFramebuffer implementation uses the memory buffer allocated and owned
10591	by the virtual machine. This buffer represents the video memory of the
10592	emulated video adapter (so called <i>guest VRAM</i>). The direct mode is
10593	usually faster because the implementation gets a raw pointer to the
10594	guest VRAM buffer which it can directly use for visualizing the contents
10595	of the virtual display, as opposed to the indirect mode where the
10596	contents of guest VRAM are copied to the memory buffer provided by
10597	the implementation every time a display update occurs.
10598
10599	It is important to note that the direct mode is really fast only when
10600	the implementation uses the given guest VRAM buffer directly, for
10601	example, by blitting it to the window representing the virtual machine's
10602	display, which saves at least one copy operation comparing to the
10603	indirect mode. However, using the guest VRAM buffer directly is not
10604	always possible: the format and the color depth of this buffer may be
10605	not supported by the target window, or it may be unknown (opaque) as in
10606	case of text or non-linear multi-plane VGA video modes. In this case,
10607	the indirect mode (that is always available) should be used as a
10608	fallback: when the guest VRAM contents are copied to the
10609	implementation-provided memory buffer, color and format conversion is
10610	done automatically by the underlying code.
10611
10612	The @a pixelFormat parameter defines whether the direct mode is
10613	available or not. If @a pixelFormat is <link
10614	to="FramebufferPixelFormat_Opaque"/> then direct access to the guest
10615	VRAM buffer is not available -- the @a VRAM, @a bitsPerPixel and
10616	@a bytesPerLine parameters must be ignored and the implementation must use
10617	the indirect mode (where it provides its own buffer in one of the
10618	supported formats). In all other cases, @a pixelFormat together with
10619	@a bitsPerPixel and @a bytesPerLine define the format of the video memory
10620	buffer pointed to by the @a VRAM parameter and the implementation is
10621	free to choose which mode to use. To indicate that this frame buffer uses
10622	the direct mode, the implementation of the <link to="#usesGuestVRAM"/>
10623	attribute must return @c true and <link to="#address"/> must
10624	return exactly the same address that is passed in the @a VRAM parameter
10625	of this method; otherwise it is assumed that the indirect strategy is
10626	chosen.
10627
10628	The @a width and @a height parameters represent the size of the
10629	requested display mode in both modes. In case of indirect mode, the
10630	provided memory buffer should be big enough to store data of the given
10631	display mode. In case of direct mode, it is guaranteed that the given
10632	@a VRAM buffer contains enough space to represent the display mode of the
10633	given size. Note that this frame buffer's <link to="#width"/> and <link
10634	to="#height"/> attributes must return exactly the same values as
10635	passed to this method after the resize is completed (see below).
10636
10637	The @a finished output parameter determines if the implementation has
10638	finished resizing the frame buffer or not. If, for some reason, the
10639	resize cannot be finished immediately during this call, @a finished
10640	must be set to @c false, and the implementation must call
10641	<link to="IDisplay::resizeCompleted"/> after it has returned from
10642	this method as soon as possible. If @a finished is @c false, the
10643	machine will not call any frame buffer methods until
10644	<link to="IDisplay::resizeCompleted"/> is called.
10645
10646	Note that if the direct mode is chosen, the <link to="#bitsPerPixel"/>,
10647	<link to="#bytesPerLine"/> and <link to="#pixelFormat"/> attributes of
10648	this frame buffer must return exactly the same values as specified in the
10649	parameters of this method, after the resize is completed. If the
10650	indirect mode is chosen, these attributes must return values describing
10651	the format of the implementation's own memory buffer <link
10652	to="#address"/> points to. Note also that the <link to="#bitsPerPixel"/>
10653	value must always correlate with <link to="#pixelFormat"/>. Note that
10654	the <link to="#pixelFormat"/> attribute must never return <link
10655	to="FramebufferPixelFormat_Opaque"/> regardless of the selected mode.

10658	This method is called by the IDisplay object under the

11360	The virtual serial port device acts like an ordinary serial port

11363
11364	In host pipe mode, the #path attribute specifies the path to the pipe on
11365	the host computer that represents a serial port. The #server attribute
11366	determines if this pipe is created by the virtual machine process at
11367	machine startup or it must already exist before starting machine
11368	execution.
11369
11370	In host device mode, the #path attribute specifies the name of the
11371	serial port device on the host computer.
11372
11373	There is also a third communication mode: the disconnected mode. In this
11374	mode, the guest OS running inside the virtual machine will be able to
11375	detect the serial port, but all port write operations will be discarded
11376	and all port read operations will return no data.

11870	<desc>
11871	The IUSBDeviceFilter interface represents an USB device filter used
11872	to perform actions on a group of USB devices.
11873
11874	This type of filters is used by running virtual machines to
11875	automatically capture selected USB devices once they are physically
11876	attached to the host computer.
11877
11878	A USB device is matched to the given device filter if and only if all
11879	attributes of the device match the corresponding attributes of the
11880	filter (that is, attributes are joined together using the logical AND
11881	operation). On the other hand, all together, filters in the list of
11882	filters carry the semantics of the logical OR operation. So if it is
11883	desirable to create a match like "this vendor id OR this product id",
11884	one needs to create two filters and specify "any match" (see below)
11885	for unused attributes.
11886
11887	All filter attributes used for matching are strings. Each string
11888	is an expression representing a set of values of the corresponding
11889	device attribute, that will match the given filter. Currently, the
11890	following filtering expressions are supported:
11891
11892	<ul>
11893	<li><i>Interval filters</i>. Used to specify valid intervals for
11894	integer device attributes (Vendor ID, Product ID and Revision).
11895	The format of the string is:
11896
11897	<tt>int:((m)\|([m]-[n]))(,(m)\|([m]-[n]))*</tt>
11898
11899	where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
11900	(starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
11901	or decimal (otherwise) form, so that <tt>m < n</tt>. If <tt>m</tt>
11902	is omitted before a dash (<tt>-</tt>), the minimum possible integer
11903	is assumed; if <tt>n</tt> is omitted after a dash, the maximum
11904	possible integer is assumed.
11905	</li>
11906	<li><i>Boolean filters</i>. Used to specify acceptable values for
11907	boolean device attributes. The format of the string is:
11908
11909	<tt>true\|false\|yes\|no\|0\|1</tt>
11910
11911	</li>
11912	<li><i>Exact match</i>. Used to specify a single value for the given
11913	device attribute. Any string that doesn't start with <tt>int:</tt>
11914	represents the exact match. String device attributes are compared to
11915	this string including case of symbols. Integer attributes are first
11916	converted to a string (see individual filter attributes) and then
11917	compared ignoring case.
11918
11919	</li>
11920	<li><i>Any match</i>. Any value of the corresponding device attribute
11921	will match the given filter. An empty or @c null string is
11922	used to construct this type of filtering expressions.
11923
11924	</li>
11925	</ul>
11926
11927	<note>
11928	On the Windows host platform, interval filters are not currently
11929	available. Also all string filter attributes
11930	(<link to="#manufacturer"/>, <link to="#product"/>,
11931	<link to="#serialNumber"/>) are ignored, so they behave as
11932	<i>any match</i> no matter what string expression is specified.

11976	Note that for interval filters, it's best to use the hexadecimal

11978	so the expression <tt>int:0x0100-0x0199</tt> will match any

12041	of the USB device physically attached to the host computer regarding
12042	its state on the host computer and availability to guest computers
12043	(all currently running virtual machines).
12044
12045	Once a supported USB device is attached to the host, global USB
12046	filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
12047	either ignore the device, or put it to USBDeviceState_Held state, or do
12048	nothing. Unless the device is ignored by global filters, filters of all
12049	currently running guests (<link to="IUSBController::deviceFilters"/>) are
12050	activated that can put it to USBDeviceState_Captured state.
12051
12052	If the device was ignored by global filters, or didn't match
12053	any filters at all (including guest ones), it is handled by the host
12054	in a normal way. In this case, the device state is determined by
12055	the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
12056	or USBDeviceState_Available, depending on the current device usage.
12057
12058	Besides auto-capturing based on filters, the device can be manually
12059	captured by guests (<link to="IConsole::attachUSBDevice"/>) if its
12060	state is USBDeviceState_Busy, USBDeviceState_Available or
12061	USBDeviceState_Held.
12062
12063	<note>
12064	Due to differences in USB stack implementations in Linux and Win32,
12065	states USBDeviceState_Busy and USBDeviceState_vailable are applicable
12066	only to the Linux version of the product. This also means that (<link
12067	to="IConsole::attachUSBDevice"/>) can only succeed on Win32 if the
12068	device state is USBDeviceState_Held.

12366	name="ISharedFolder" extends="$unknown"

12369	>
12370	<desc>
12371	The ISharedFolder interface represents a folder in the host computer's
12372	file system accessible from the guest OS running inside a virtual
12373	machine using an associated logical name.
12374
12375	There are three types of shared folders:
12376	<ul>
12377	<li><i>Global</i> (<link to="IVirtualBox::sharedFolders"/>), shared
12378	folders available to all virtual machines.</li>
12379	<li><i>Permanent</i> (<link to="IMachine::sharedFolders"/>),
12380	VM-specific shared folders available to the given virtual machine at
12381	startup.</li>
12382	<li><i>Transient</i> (<link to="IConsole::sharedFolders"/>),
12383	VM-specific shared folders created in the session context (for
12384	example, when the virtual machine is running) and automatically
12385	discarded when the session is closed (the VM is powered off).</li>
12386	</ul>
12387
12388	Logical names of shared folders must be unique within the given scope
12389	(global, permanent or transient). However, they do not need to be unique
12390	across scopes. In this case, the definition of the shared folder in a
12391	more specific scope takes precedence over definitions in all other
12392	scopes. The order of precedence is (more specific to more general):
12393	<ol>
12394	<li>Transient definitions</li>
12395	<li>Permanent definitions</li>
12396	<li>Global definitions</li>
12397	</ol>
12398
12399	For example, if MyMachine has a shared folder named
12400	<tt>C_DRIVE</tt> (that points to <tt>C:\\</tt>), then creating a
12401	transient shared folder named <tt>C_DRIVE</tt> (that points
12402	to <tt>C:\\\\WINDOWS</tt>) will change the definition
12403	of <tt>C_DRIVE</tt> in the guest OS so
12404	that <tt>\\\\VBOXSVR\\C_DRIVE</tt> will give access
12405	to <tt>C:\\WINDOWS</tt> instead of <tt>C:\\</tt> on the host
12406	PC. Removing the transient shared folder <tt>C_DRIVE</tt> will restore
12407	the previous (permanent) definition of <tt>C_DRIVE</tt> that points
12408	to <tt>C:\\</tt> if it still exists.
12409
12410	Note that permanent and transient shared folders of different machines
12411	are in different name spaces, so they don't overlap and don't need to
12412	have unique logical names.
12413
12414	<note>
12415	Global shared folders are not implemented in the current version of the
12416	product.

12898	<desc>
12899	The ISession interface represents a client process and allows for locking
12900	virtual machines (represented by IMachine objects) to prevent conflicting
12901	changes to the machine.
12902
12903	Any caller wishing to manipulate a virtual machine needs to create a session
12904	object first, which lives in its own process space. Such session objects are
12905	then associated with <link to="IMachine" /> objects living in the VirtualBox
12906	server process to coordinate such changes.
12907
12908	There are two typical scenarios in which sessions are used:
12909
12910	<ul>
12911	<li>To alter machine settings or control a running virtual machine, one
12912	needs to lock a machine for a given session (client process) by calling
12913	<link to="IMachine::lockMachine"/>.
12914
12915	Whereas multiple sessions may control a running virtual machine, only
12916	one process can obtain a write lock on the machine to prevent conflicting
12917	changes. A write lock is also needed if a process wants to actually run a
12918	virtual machine in its own context, such as the VirtualBox GUI or
12919	VBoxHeadless front-ends. They must also lock a machine for their own
12920	sessions before they are allowed to power up the virtual machine.
12921
12922	As a result, no machine settings can be altered while another process is
12923	already using it, either because that process is modifying machine settings
12924	or because the machine is running.
12925	</li>
12926	<li>
12927	To start a VM using one of the existing VirtualBox front-ends (e.g. the
12928	VirtualBox GUI or VBoxHeadless), one would use
12929	<link to="IMachine::launchVMProcess"/>, which also takes a session object
12930	as its first parameter. This session then identifies the caller and lets the
12931	caller control the started machine (for example, pause machine execution or
12932	power it down) as well as be notified about machine execution state changes.
12933	</li>
12934	</ul>
12935
12936	How sessions objects are created in a client process depends on whether you use
12937	the Main API via COM or via the webservice:
12938
12939	<ul>
12940	<li>When using the COM API directly, an object of the Session class from the
12941	VirtualBox type library needs to be created. In regular COM C++ client code,
12942	this can be done by calling <tt>createLocalObject()</tt>, a standard COM API.
12943	This object will then act as a local session object in further calls to open
12944	a session.
12945	</li>
12946
12947	<li>In the webservice, the session manager (IWebsessionManager) instead creates
12948	a session object automatically whenever <link to="IWebsessionManager::logon" />
12949	is called. A managed object reference to that session object can be retrieved by
12950	calling <link to="IWebsessionManager::getSessionObject" />.
12951	</li>
12952	</ul>

12980	for a particular session using the <link to="IMachine::launchVMProcess" />
12981	or <link to="IMachine::lockMachine" /> calls. Otherwise the state of
12982	the machine will be set to <link to="MachineState_Aborted" /> on the
12983	server, and changes made to the machine settings will be lost.
12984
12985	Generally, it is recommended to unlock all machines explicitly
12986	before terminating the application (regardless of the reason for
12987	the termination).
12988
12989	<note>
12990	Do not expect the session state (<link to="ISession::state" />
12991	to return to "Unlocked" immediately after you invoke this method,
12992	particularly if you have started a new VM process. The session
12993	state will automatically return to "Unlocked" once the VM is no
12994	longer executing, which can of course take a very long time.

13399	<desc>
13400	The IPerformanceCollector interface represents a service that collects
13401	and stores performance metrics data.
13402
13403	Performance metrics are associated with objects of interfaces like IHost
13404	and IMachine. Each object has a distinct set of performance metrics. The
13405	set can be obtained with <link to="IPerformanceCollector::getMetrics"/>.
13406
13407	Metric data is collected at the specified intervals and is retained
13408	internally. The interval and the number of retained samples can be set
13409	with <link to="IPerformanceCollector::setupMetrics" />. Both metric data
13410	and collection settings are not persistent, they are discarded as soon as
13411	VBoxSVC process terminates. Moreover, metric settings and data associated
13412	with a particular VM only exist while VM is running. They disappear as
13413	soon as VM shuts down. It is not possible to set up metrics for machines
13414	that are powered off. One needs to start VM first, then set up metric
13415	collection parameters.
13416
13417	Metrics are organized hierarchically, with each level separated by a
13418	slash (/) character. Generally, the scheme for metric names is like this:
13419
13420	<tt>Category/Metric[/SubMetric][:aggregation]</tt>
13421
13422	"Category/Metric" together form the base metric name. A base metric is
13423	the smallest unit for which a sampling interval and the number of
13424	retained samples can be set. Only base metrics can be enabled and
13425	disabled. All sub-metrics are collected when their base metric is
13426	collected. Collected values for any set of sub-metrics can be queried
13427	with <link to="IPerformanceCollector::queryMetricsData" />.
13428
13429	For example "CPU/Load/User:avg" metric name stands for the "CPU"
13430	category, "Load" metric, "User" submetric, "average" aggregate. An
13431	aggregate function is computed over all retained data. Valid aggregate
13432	functions are:
13433
13434	<ul>
13435	<li>avg -- average</li>
13436	<li>min -- minimum</li>
13437	<li>max -- maximum</li>
13438	</ul>
13439
13440	When setting up metric parameters, querying metric data, enabling or
13441	disabling metrics wildcards can be used in metric names to specify a
13442	subset of metrics. For example, to select all CPU-related metrics
13443	use <tt>CPU/</tt>, all averages can be queried using <tt>:avg</tt> and
13444	so on. To query metric values without aggregates <tt>*:</tt> can be used.
13445
13446	The valid names for base metrics are:
13447
13448	<ul>
13449	<li>CPU/Load</li>
13450	<li>CPU/MHz</li>
13451	<li>RAM/Usage</li>
13452	</ul>
13453
13454	The general sequence for collecting and retrieving the metrics is:
13455	<ul>
13456	<li>
13457	Obtain an instance of IPerformanceCollector with
13458	<link to="IVirtualBox::performanceCollector" />
13459	</li>
13460	<li>
13461	Allocate and populate an array with references to objects the metrics
13462	will be collected for. Use references to IHost and IMachine objects.
13463	</li>
13464	<li>
13465	Allocate and populate an array with base metric names the data will
13466	be collected for.
13467	</li>
13468	<li>
13469	Call <link to="IPerformanceCollector::setupMetrics" />. From now on
13470	the metric data will be collected and stored.
13471	</li>
13472	<li>
13473	Wait for the data to get collected.
13474	</li>
13475	<li>
13476	Allocate and populate an array with references to objects the metric
13477	values will be queried for. You can re-use the object array used for
13478	setting base metrics.
13479	</li>
13480	<li>
13481	Allocate and populate an array with metric names the data will be
13482	collected for. Note that metric names differ from base metric names.
13483	</li>
13484	<li>
13485	Call <link to="IPerformanceCollector::queryMetricsData" />. The data
13486	that have been collected so far are returned. Note that the values
13487	are still retained internally and data collection continues.
13488	</li>
13489	</ul>

14262	Abstract parent interface for VirtualBox events. Actual events will typically implement
14263	a more specific interface which derives from this (see below).
14264
14265	<b>Introduction to VirtualBox events</b>
14266
14267	Generally speaking, an event (represented by this interface) signals that something
14268	happened, while an event listener (see <link to="IEventListener" />) represents an
14269	entity that is interested in certain events. In order for this to work with
14270	unidirectional protocols (i.e. web services), the concepts of passive and active
14271	listener are used.
14272
14273	Event consumers can register themselves as listeners, providing an array of
14274	events they are interested in (see <link to="IEventSource::registerListener" />).
14275	When an event triggers, the listener is notified about the event. The exact
14276	mechanism of the notification depends on whether the listener was registered as
14277	an active or passive listener:
14278
14279	<ul>
14280	<li>An active listener is very similar to a callback: it is a function invoked
14281	by the API. As opposed to the callbacks that were used in the API before
14282	VirtualBox 3.3 however, events are now objects with an interface hierarchy.
14283	</li>
14284
14285	<li>Passive listeners are somewhat tricker to implement, but do not require
14286	a client function to be callable, which is not an option with scripting
14287	languages or web service clients. Internally the <link to="IEventSource" />
14288	implementation maintains an event queue for each passive listener, and
14289	newly arrived events are put in this queue. When the listener calls
14290	<link to="IEventSource::getEvent"/>, first element from its internal event
14291	queue is returned. When the client completes processing of an event,
14292	the <link to="IEventSource::eventProcessed" /> function must be called,
14293	acknowledging that the event was processed. It supports implementing
14294	waitable events. On passive listener unregistration, all events from its
14295	queue are auto-acknowledged.
14296	</li>
14297	</ul>
14298
14299	Waitable events are useful in situations where the event generator wants to track
14300	delivery or a party wants to wait until all listeners have completed the event. A
14301	typical example would be a vetoable event (see <link to="IVetoEvent" />) where a
14302	listeners might veto a certain action, and thus the event producer has to make
14303	sure that all listeners have processed the event and not vetoed before taking
14304	the action.
14305
14306	A given event may have both passive and active listeners at the same time.
14307
14308	<b>Using events</b>
14309
14310	Any VirtualBox object capable of producing externally visible events provides an
14311	@c eventSource read-only attribute, which is of the type <link to="IEventSource" />.
14312	This event source object is notified by VirtualBox once something has happened, so
14313	consumers may register event listeners with this event source. To register a listener,
14314	an object implementing the <link to="IEventListener" /> interface must be provided.
14315	For active listeners, such an object is typically created by the consumer, while for
14316	passive listeners <link to="IEventSource::createListener" /> should be used. Please
14317	note that a listener created with @c createListener() must not be used as an active listener.
14318
14319	Once created, the listener must be registered to listen for the desired events
14320	(see <link to="IEventSource::registerListener" />), providing an array of
14321	<link to="VBoxEventType" /> enums. Those elements can either be the individual
14322	event IDs or wildcards matching multiple event IDs.
14323
14324	After registration, the callback's <link to="IEventListener::handleEvent" /> method is
14325	called automatically when the event is triggered, while passive listeners have to call
14326	<link to="IEventSource::getEvent" /> and <link to="IEventSource::eventProcessed" /> in
14327	an event processing loop.
14328
14329	The IEvent interface is an abstract parent interface for all such VirtualBox events
14330	coming in. As a result, the standard use pattern inside <link to="IEventListener::handleEvent" />
14331	or the event processing loop is to check the <link to="#type" /> attribute of the event and
14332	then cast to the appropriate specific interface using @c QueryInterface().

14351	as no additional overhead associated with waitability imposed.
14352	Waitable events are needed when one need to be able to wait for particular event processed,
14353	for example for vetoable changes, or if event refers to some resource which need to be kept immutable

14959	<desc>
14960	Notification when an error happens during the virtual
14961	machine execution.
14962
14963	There are three kinds of runtime errors:
14964	<ul>
14965	<li><i>fatal</i></li>
14966	<li><i>non-fatal with retry</i></li>
14967	<li><i>non-fatal warnings</i></li>
14968	</ul>
14969
14970	<b>Fatal</b> errors are indicated by the @a fatal parameter set
14971	to @c true. In case of fatal errors, the virtual machine
14972	execution is always paused before calling this notification, and
14973	the notification handler is supposed either to immediately save
14974	the virtual machine state using <link to="IConsole::saveState"/>
14975	or power it off using <link to="IConsole::powerDown"/>.
14976	Resuming the execution can lead to unpredictable results.
14977
14978	<b>Non-fatal</b> errors and warnings are indicated by the
14979	@a fatal parameter set to @c false. If the virtual machine
14980	is in the Paused state by the time the error notification is
14981	received, it means that the user can <i>try to resume</i> the machine
14982	execution after attempting to solve the problem that caused the
14983	error. In this case, the notification handler is supposed
14984	to show an appropriate message to the user (depending on the
14985	value of the @a id parameter) that offers several actions such
14986	as <i>Retry</i>, <i>Save</i> or <i>Power Off</i>. If the user
14987	wants to retry, the notification handler should continue
14988	the machine execution using the <link to="IConsole::resume"/>
14989	call. If the machine execution is not Paused during this
14990	notification, then it means this notification is a <i>warning</i>
14991	(for example, about a fatal condition that can happen very soon);
14992	no immediate action is required from the user, the machine
14993	continues its normal execution.
14994
14995	Note that in either case the notification handler
14996	<b>must not</b> perform any action directly on a thread
14997	where this notification is called. Everything it is allowed to
14998	do is to post a message to another thread that will then talk
14999	to the user and take the corresponding action.
15000
15001	Currently, the following error identifiers are known:
15002	<ul>
15003	<li><tt>"HostMemoryLow"</tt></li>

15174	Notification when a call to
15175	<link to="IMachine::showConsoleWindow"/>
15176	requests the console window to be activated and brought to
15177	foreground on the desktop of the host PC.
15178
15179	This notification should cause the VM console process to
15180	perform the requested action as described above. If it is
15181	impossible to do it at a time of this notification, this
15182	method should return a failure.
15183
15184	Note that many modern window managers on many platforms
15185	implement some sort of focus stealing prevention logic, so
15186	that it may be impossible to activate a window without the
15187	help of the currently active application (which is supposedly
15188	an initiator of this notification). In this case, this method
15189	must return a non-zero identifier that represents the
15190	top-level window of the VM console process. The caller, if it
15191	represents a currently active process, is responsible to use
15192	this identifier (in a platform-dependent manner) to perform
15193	actual window activation.
15194
15195	This method must set @a winId to zero if it has performed all
15196	actions necessary to complete the request and the console
15197	window is now active and in foreground, to indicate that no
15198	further action is required on the caller's side.
