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	and the VBoxManage command-line interface) 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.

512	Virtual machine execution state.
513
514	This enumeration represents possible values of the <link
515	to="IMachine::state"/> attribute.
516
517	Below is the basic virtual machine state diagram. It shows how the state
518	changes during virtual machine execution. The text in square braces shows
519	a method of the IConsole interface that performs the given state
520	transition.
521

528	\| \| ^ \| ^ \|

534	\| \| \| \|
535	\| +-------- Saving <--------[saveState()]<----------+---------------------+
536	\| \| \|
537	+-------------- Stopping -------[powerDown()]<----------+---------------------+
538	</pre>
539
540	Note that states to the right from PoweredOff, Aborted and Saved in the
541	above diagram are called <i>online VM states</i>. These states
542	represent the virtual machine which is being executed in a dedicated
543	process (usually with a GUI window attached to it where you can see the
544	activity of the virtual machine and interact with it). There are two
545	special pseudo-states, FirstOnline and LastOnline, that can be used in
546	relational expressions to detect if the given machine state is online or
547	not:
548
549	<pre>
550	if (machine.GetState() >= MachineState_FirstOnline &&
551	machine.GetState() <= MachineState_LastOnline)
552	{
553	...the machine is being executed...
554	}
555	</pre>
556
557	When the virtual machine is in one of the online VM states (that is, being
558	executed), only a few machine settings can be modified. Methods working
559	with such settings contain an explicit note about that. An attempt to
560	change any oter setting or perform a modifying operation during this time
561	will result in the <link to="VBOX_E_INVALID_VM_STATE"/> error.
562
563	All online states except Running, Paused and Stuck are transitional: they
564	represent temporary conditions of the virtual machine that will last as
565	long as the operation that initiated such a condition.
566
567	The Stuck state is a special case. It means that execution of the machine
568	has reached the "Guru Meditation" condition. This condition indicates an
569	internal VMM (virtual machine manager) failure which may happen as a
570	result of either an unhandled low-level virtual hardware exception or one
571	of the recompiler exceptions (such as the <i>too-many-traps</i>
572	condition).
573
574	Note also that any online VM state may transit to the Aborted state. This
575	happens if the process that is executing the virtual machine terminates
576	unexpectedly (for example, crashes). Other than that, the Aborted state is
577	equivalent to PoweredOff.
578
579	There are also a few additional state diagrams that do not deal with
580	virtual machine execution and therefore are shown separately. The states
581	shown on these diagrams are called <i>offline VM states</i> (this includes
582	PoweredOff, Aborted and Saved too).
583
584	The first diagram shows what happens when a lengthy setup operation is
585	being executed (such as <link to="IMachine::attachDevice"/>).
586
587	<pre>
588	+----------------------------------(same state as before the call)------+
589	\| \|
590	+-> PoweredOff --+ \|
591	\| \| \|
592	\|-> Aborted -----+-->[lengthy VM configuration call] --> SettingUp -----+
593	\| \|
594	+-> Saved -------+
595	</pre>
596
597	The next two diagrams demonstrate the process of taking a snapshot of a
598	powered off virtual machine, restoring the state to that as of a snapshot
599	or deleting a snapshot, respectively.
600
601	<pre>
602	+----------------------------------(same state as before the call)------+
603	\| \|
604	+-> PoweredOff --+ \|
605	\| +-->[takeSnapshot()] -------------------> Saving ------+
606	+-> Aborted -----+
607
608	+-> PoweredOff --+
609	\| \|
610	\| Aborted -----+-->[restoreSnapshot() ]-------> RestoringSnapshot -+
611	\| \| [deleteSnapshot() ]-------> DeletingSnapshot --+
612	+-> Saved -------+ \|
613	\| \|
614	+---(Saved if restored from an online snapshot, PoweredOff otherwise)---+
615	</pre>
616
617	Note that the Saving state is present in both the offline state group and
618	online state group. Currently, the only way to determine what group is
619	assumed in a particular case is to remember the previous machine state: if
620	it was Running or Paused, then Saving is an online state, otherwise it is
621	an offline state. This inconsistency may be removed in one of the future
622	versions of VirtualBox by adding a new state.
623
624	<note internal="yes">
625	For whoever decides to touch this enum: In order to keep the
626	comparisons involving FirstOnline and LastOnline pseudo-states valid,
627	the numeric values of these states must be correspondingly updated if
628	needed: for any online VM state, the condition
629	<tt>FirstOnline <= state <= LastOnline</tt> must be
630	@c true. The same relates to transient states for which
631	the condition <tt>FirstOnline <= state <= LastOnline</tt> must be
632	@c true.

1185	>
1186	<desc>
1187	The IVirtualBoxErrorInfo interface represents extended error information.
1188
1189	Extended error information can be set by VirtualBox components after
1190	unsuccessful or partially successful method invocation. This information
1191	can be retrieved by the calling party as an IVirtualBoxErrorInfo object
1192	and then shown to the client in addition to the plain 32-bit result code.
1193
1194	In MS COM, this interface extends the IErrorInfo interface,
1195	in XPCOM, it extends the nsIException interface. In both cases,
1196	it provides a set of common attributes to retrieve error
1197	information.
1198
1199	Sometimes invocation of some component's method may involve methods of
1200	other components that may also fail (independently of this method's
1201	failure), or a series of non-fatal errors may precede a fatal error that
1202	causes method failure. In cases like that, it may be desirable to preserve
1203	information about all errors happened during method invocation and deliver
1204	it to the caller. The <link to="#next"/> attribute is intended
1205	specifically for this purpose and allows to represent a chain of errors
1206	through a single IVirtualBoxErrorInfo object set after method invocation.
1207
1208	Note that errors are stored to a chain in the reverse order, i.e. the
1209	initial error object you query right after method invocation is the last
1210	error set by the callee, the object it points to in the @a next attribute
1211	is the previous error and so on, up to the first error (which is the last
1212	in the chain).

1220	always. For example, on Win32, CoCreateInstance() will most
1221	likely return E_NOINTERFACE upon unsuccessful component
1222	instantiation attempt, but not the value the component factory
1223	returned. Value is typed 'long', not 'result',
1224	to make interface usable from scripting languages.

1585	<desc>
1586	Creates a new virtual machine by creating a machine settings file at
1587	the given location.
1588
1589	VirtualBox machine settings files use a custom XML dialect. Starting
1590	with VirtualBox 4.0, a ".vbox" extension is recommended, but not enforced,
1591	and machine files can be created at arbitrary locations.
1592
1593	However, it is is recommended that machines be created in the default
1594	machine folder (e.g. "/home/user/VirtualBox VMs/name/name.vbox"; see
1595	<link to="ISystemProperties::defaultMachineFolder" />). If you specify
1596	NULL for the @a settingsFile argument, <link to="#composeMachineFilename" />
1597	is called automatically to have such a recommended name composed based
1598	on the machine name given in the @a name argument.
1599
1600	If the resulting settings file already exists, this method will fail,
1601	unless @a forceOverwrite is set.
1602
1603	The new machine is created unregistered, with the initial configuration
1604	set according to the specified guest OS type. A typical sequence of
1605	actions to create a new virtual machine is as follows:
1606
1607	<ol>
1608	<li>
1609	Call this method to have a new machine created. The returned machine
1610	object will be "mutable" allowing to change any machine property.
1611	</li>
1612
1613	<li>
1614	Configure the machine using the appropriate attributes and methods.
1615	</li>
1616
1617	<li>
1618	Call <link to="IMachine::saveSettings" /> to write the settings
1619	to the machine's XML settings file. The configuration of the newly
1620	created machine will not be saved to disk until this method is
1621	called.
1622	</li>
1623
1624	<li>
1625	Call <link to="#registerMachine" /> to add the machine to the list
1626	of machines known to VirtualBox.
1627	</li>
1628	</ol>
1629
1630	The specified guest OS type identifier must match an ID of one of known
1631	guest OS types listed in the <link to="IVirtualBox::guestOSTypes"/>
1632	array.
1633
1634	Optionally, you may specify an UUID of to assign to the created machine.
1635	However, this is not recommended and you should normally pass an empty
1636	(@c null) UUID to this method so that a new UUID will be automatically
1637	generated for every created machine. You can use UUID
1638	00000000-0000-0000-0000-000000000000 as @c null value.

1768
1769	Note that the actual storage unit is not created by this method. In
1770	order to do it, and before you are able to attach the created medium
1771	to virtual machines, you must call one of the following methods to
1772	allocate a format-specific storage unit at the specified location:

1785
1786	The list of all storage formats supported by this VirtualBox

1821	Opens a medium from an existing storage location.
1822
1823	Once a medium has been opened, it can be passed to other VirtualBox
1824	methods, in particular to <link to="IMachine::attachDevice" />.
1825
1826	Depending on the given device type, the file at the storage location
1827	must be in one of the media formats understood by VirtualBox:
1828
1829	<ul>
1830	<li>With a "HardDisk" device type, the file must be a hard disk image
1831	in one of the formats supported by VirtualBox (see
1832	<link to="ISystemProperties::mediumFormats" />).
1833	After this method succeeds, if the medium is a base medium, it
1834	will be added to the <link to="#hardDisks"/> array attribute. </li>
1835	<li>With a "DVD" device type, the file must be an ISO 9960 CD/DVD image.
1836	After this method succeeds, the medium will be added to the
1837	<link to="#DVDImages"/> array attribute.</li>
1838	<li>With a "Floppy" device type, the file must be an RAW floppy image.
1839	After this method succeeds, the medium will be added to the
1840	<link to="#floppyImages"/> array attribute.</li>
1841	</ul>
1842
1843	After having been opened, the medium can be found by the <link to="#findMedium"/>
1844	method and can be attached to virtual machines. See <link to="IMedium" /> for more details.
1845
1846	The UUID of the newly opened medium will either be retrieved from the
1847	storage location, if the format supports it (e.g. for hard disk images),
1848	or a new UUID will be randomly generated (e.g. for ISO and RAW files).
1849	If for some reason you need to change the medium's UUID, use
1850	<link to="IMedium::setIDs" />.
1851
1852	If a differencing hard disk medium is to be opened by this method, the
1853	operation will succeed only if its parent medium and all ancestors,
1854	if any, are already known to this VirtualBox installation (for example,
1855	were opened by this method before).
1856
1857	This method attempts to guess the storage format of the specified medium
1858	by reading medium data at the specified location.
1859
1860	If @a accessMode is ReadWrite (which it should be for hard disks and floppies),
1861	the image is opened for read/write access and must have according permissions,
1862	as VirtualBox may actually write status information into the disk's metadata
1863	sections.
1864
1865	Note that write access is required for all typical hard disk usage in VirtualBox,
1866	since VirtualBox may need to write metadata such as a UUID into the image.
1867	The only exception is opening a source image temporarily for copying and
1868	cloning (see <link to="IMedium::cloneTo" /> when the image will be closed
1869	again soon.

2338	Represents a platform-independent appliance in OVF format. An instance of this is returned
2339	by <link to="IVirtualBox::createAppliance" />, which can then be used to import and export
2340	virtual machines within an appliance with VirtualBox.
2341
2342	The OVF standard suggests two different physical file formats:
2343
2344	<ol>
2345	<li>If the appliance is distributed as a set of files, there must be at least one XML descriptor
2346	file that conforms to the OVF standard and carries an <tt>.ovf</tt> file extension. If
2347	this descriptor file references other files such as disk images, as OVF appliances typically
2348	do, those additional files must be in the same directory as the descriptor file.</li>
2349
2350	<li>If the appliance is distributed as a single file, it must be in TAR format and have the
2351	<tt>.ova</tt> file extension. This TAR file must then contain at least the OVF descriptor
2352	files and optionally other files.
2353
2354	At this time, VirtualBox does not not yet support the packed (TAR) variant; support will
2355	be added with a later version.</li>
2356	</ol>
2357
2358	<b>Importing</b> an OVF appliance into VirtualBox as instances of
2359	<link to="IMachine" /> involves the following sequence of API calls:
2360
2361	<ol>
2362	<li>Call <link to="IVirtualBox::createAppliance" />. This will create an empty IAppliance object.
2363	</li>
2364
2365	<li>On the new object, call <link to="#read" /> with the full path of the OVF file you
2366	would like to import. So long as this file is syntactically valid, this will succeed
2367	and fill the appliance object with the parsed data from the OVF file.
2368	</li>
2369
2370	<li>Next, call <link to="#interpret" />, which analyzes the OVF data and sets up the
2371	contents of the IAppliance attributes accordingly. These can be inspected by a
2372	VirtualBox front-end such as the GUI, and the suggestions can be displayed to the
2373	user. In particular, the <link to="#virtualSystemDescriptions" /> array contains
2374	instances of <link to="IVirtualSystemDescription" /> which represent the virtual
2375	systems (machines) in the OVF, which in turn describe the virtual hardware prescribed
2376	by the OVF (network and hardware adapters, virtual disk images, memory size and so on).
2377	The GUI can then give the user the option to confirm and/or change these suggestions.
2378	</li>
2379
2380	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
2381	virtual system (machine) to override the suggestions made by the interpret() routine.
2382	</li>
2383
2384	<li>Finally, call <link to="#importMachines" /> to create virtual machines in
2385	VirtualBox as instances of <link to="IMachine" /> that match the information in the
2386	virtual system descriptions. After this call succeeded, the UUIDs of the machines created
2387	can be found in the <link to="#machines" /> array attribute.
2388	</li>
2389	</ol>
2390
2391	<b>Exporting</b> VirtualBox machines into an OVF appliance involves the following steps:
2392
2393	<ol>
2394	<li>As with importing, first call <link to="IVirtualBox::createAppliance" /> to create
2395	an empty IAppliance object.
2396	</li>
2397
2398	<li>For each machine you would like to export, call <link to="IMachine::export" />
2399	with the IAppliance object you just created. Each such call creates one instance of
2400	<link to="IVirtualSystemDescription" /> inside the appliance.
2401	</li>
2402
2403	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
2404	virtual system (machine) to override the suggestions made by the export() routine.
2405	</li>
2406
2407	<li>Finally, call <link to="#write" /> with a path specification to have the OVF
2408	file written.</li>
2409	</ol>
2410
2411	</desc>
2412
2413	<attribute name="path" type="wstring" readonly="yes">
2414	<desc>Path to the main file of the OVF appliance, which is either the <tt>.ovf</tt> or
2415	the <tt>.ova</tt> file passed to <link to="#read" /> (for import) or

2426
2427	The caller should be prepared for additional fields being appended to
2428	this string in future versions of VirtualBox and therefore check for
2429	the number of tabs in the strings returned.

2446	then the disk should be created on import)</li>
2447
2448	<li>Image size (optional unsigned integer indicating the size of the image,

2656	<method name="getDescription">
2657	<desc>Returns information about the virtual system as arrays of instruction items. In each array, the
2658	items with the same indices correspond and jointly represent an import instruction for VirtualBox.
2659
2660	The list below identifies the value sets that are possible depending on the
2661	<link to="VirtualSystemDescriptionType" /> enum value in the array item in @a aTypes[]. In each case,
2662	the array item with the same index in @a aOvfValues[] will contain the original value as contained
2663	in the OVF file (just for informational purposes), and the corresponding item in @a aVBoxValues[]
2664	will contain a suggested value to be used for VirtualBox. Depending on the description type,
2665	the @a aExtraConfigValues[] array item may also be used.
2666
2667	<ul>
2668	<li>
2669	"OS": the guest operating system type. There must be exactly one such array item on import. The
2670	corresponding item in @a aVBoxValues[] contains the suggested guest operating system for VirtualBox.
2671	This will be one of the values listed in <link to="IVirtualBox::guestOSTypes" />. The corresponding
2672	item in @a aOvfValues[] will contain a numerical value that described the operating system in the OVF.
2673	</li>
2674	<li>
2675	"Name": the name to give to the new virtual machine. There can be at most one such array item;
2676	if none is present on import, then an automatic name will be created from the operating system
2677	type. The corresponding item im @a aOvfValues[] will contain the suggested virtual machine name
2678	from the OVF file, and @a aVBoxValues[] will contain a suggestion for a unique VirtualBox
2679	<link to="IMachine" /> name that does not exist yet.
2680	</li>
2681	<li>
2682	"Description": an arbitrary description.
2683	</li>
2684	<li>
2685	"License": the EULA section from the OVF, if present. It is the responsibility of the calling
2686	code to display such a license for agreement; the Main API does not enforce any such policy.
2687	</li>
2688	<li>
2689	Miscellaneous: reserved for future use.
2690	</li>
2691	<li>
2692	"CPU": the number of CPUs. There can be at most one such item, which will presently be ignored.
2693	</li>
2694	<li>
2695	"Memory": the amount of guest RAM, in bytes. There can be at most one such array item; if none
2696	is present on import, then VirtualBox will set a meaningful default based on the operating system
2697	type.
2698	</li>
2699	<li>
2700	"HardDiskControllerIDE": an IDE hard disk controller. There can be at most two such items.
2701	An optional value in @a aOvfValues[] and @a aVBoxValues[] can be "PIIX3" or "PIIX4" to specify
2702	the type of IDE controller; this corresponds to the ResourceSubType element which VirtualBox
2703	writes into the OVF.
2704	The matching item in the @a aRefs[] array will contain an integer that items of the "Harddisk"
2705	type can use to specify which hard disk controller a virtual disk should be connected to.
2706	Note that in OVF, an IDE controller has two channels, corresponding to "master" and "slave"
2707	in traditional terminology, whereas the IDE storage controller that VirtualBox supports in
2708	its virtual machines supports four channels (primary master, primary slave, secondary master,
2709	secondary slave) and thus maps to two IDE controllers in the OVF sense.
2710	</li>
2711	<li>
2712	"HardDiskControllerSATA": an SATA hard disk controller. There can be at most one such item. This
2713	has no value in @a aOvfValues[] or @a aVBoxValues[].
2714	The matching item in the @a aRefs[] array will be used as with IDE controllers (see above).
2715	</li>
2716	<li>
2717	"HardDiskControllerSCSI": a SCSI hard disk controller. There can be at most one such item.
2718	The items in @a aOvfValues[] and @a aVBoxValues[] will either be "LsiLogic", "BusLogic" or
2719	"LsiLogicSas". (Note that in OVF, the LsiLogicSas controller is treated as a SCSI controller
2720	whereas VirtualBox considers it a class of storage controllers of its own; see
2721	<link to="StorageControllerType" />).
2722	The matching item in the @a aRefs[] array will be used as with IDE controllers (see above).
2723	</li>
2724	<li>
2725	"HardDiskImage": a virtual hard disk, most probably as a reference to an image file. There can be an
2726	arbitrary number of these items, one for each virtual disk image that accompanies the OVF.
2727
2728	The array item in @a aOvfValues[] will contain the file specification from the OVF file (without
2729	a path since the image file should be in the same location as the OVF file itself), whereas the
2730	item in @a aVBoxValues[] will contain a qualified path specification to where VirtualBox uses the
2731	hard disk image. This means that on import the image will be copied and converted from the
2732	"ovf" location to the "vbox" location; on export, this will be handled the other way round.
2733
2734	The matching item in the @a aExtraConfigValues[] array must contain a string of the following
2735	format: "controller=<index>;channel=<c>"
2736	In this string, <index> must be an integer specifying the hard disk controller to connect
2737	the image to. That number must be the index of an array item with one of the hard disk controller
2738	types (HardDiskControllerSCSI, HardDiskControllerSATA, HardDiskControllerIDE).
2739	In addition, <c> must specify the channel to use on that controller. For IDE controllers,
2740	this can be 0 or 1 for master or slave, respectively. For compatibility with VirtualBox versions
2741	before 3.2, the values 2 and 3 (for secondary master and secondary slave) are also supported, but
2742	no longer exported. For SATA and SCSI controllers, the channel can range from 0-29.
2743	</li>
2744	<li>
2745	"CDROM": a virtual CD-ROM drive. The matching item in @a aExtraConfigValue[] contains the same
2746	attachment information as with "HardDiskImage" items.
2747	</li>
2748	<li>
2749	"CDROM": a virtual floppy drive. The matching item in @a aExtraConfigValue[] contains the same
2750	attachment information as with "HardDiskImage" items.
2751	</li>
2752	<li>
2753	"NetworkAdapter": a network adapter. The array item in @a aVBoxValues[] will specify the hardware
2754	for the network adapter, whereas the array item in @a aExtraConfigValues[] will have a string
2755	of the "type=<X>" format, where <X> must be either "NAT" or "Bridged".
2756	</li>
2757	<li>
2758	"USBController": a USB controller. There can be at most one such item. If and only if such an
2759	item ispresent, USB support will be enabled for the new virtual machine.
2760	</li>
2761	<li>
2762	"SoundCard": a sound card. There can be at most one such item. If and only if such an item is
2763	present, sound support will be enabled for the new virtual machine. Note that the virtual
2764	machine in VirtualBox will always be presented with the standard VirtualBox soundcard, which
2765	may be different from the virtual soundcard expected by the appliance.

3503	<desc>
3504	The IMachine interface represents a virtual machine, or guest, created
3505	in VirtualBox.
3506
3507	This interface is used in two contexts. First of all, a collection of
3508	objects implementing this interface is stored in the
3509	<link to="IVirtualBox::machines"/> attribute which lists all the virtual
3510	machines that are currently registered with this VirtualBox
3511	installation. Also, once a session has been opened for the given virtual
3512	machine (e.g. the virtual machine is running), the machine object
3513	associated with the open session can be queried from the session object;
3514	see <link to="ISession"/> for details.
3515
3516	The main role of this interface is to expose the settings of the virtual
3517	machine and provide methods to change various aspects of the virtual
3518	machine's configuration. For machine objects stored in the
3519	<link to="IVirtualBox::machines"/> collection, all attributes are
3520	read-only unless explicitly stated otherwise in individual attribute
3521	and method descriptions.
3522
3523	In order to change a machine setting, a session for this machine must be
3524	opened using one of the <link to="IMachine::lockMachine" /> or
3525	<link to="IMachine::launchVMProcess"/> methods. After the
3526	machine has been successfully locked for a session, a mutable machine object
3527	needs to be queried from the session object and then the desired settings
3528	changes can be applied to the returned object using IMachine attributes and
3529	methods. See the <link to="ISession"/> interface description for more
3530	information about sessions.
3531
3532	Note that IMachine does not provide methods to control virtual machine
3533	execution (such as start the machine, or power it down) -- these methods
3534	are grouped in a separate interface called <link to="IConsole" />.

3543	<attribute name="accessible" type="boolean" readonly="yes">
3544	<desc>
3545	Whether this virtual machine is currently accessible or not.
3546
3547	A machine is always deemed accessible unless it is registered <i>and</i>
3548	its settings file cannot be read or parsed (either because the file itself
3549	is unavailable or has invalid XML contents).
3550
3551	Every time this property is read, the accessibility state of
3552	this machine is re-evaluated. If the returned value is @c false,
3553	the <link to="#accessError"/> property may be used to get the
3554	detailed error information describing the reason of
3555	inaccessibility, including XML error messages.
3556
3557	When the machine is inaccessible, only the following properties
3558	can be used on it:
3559	<ul>
3560	<li><link to="#parent"/></li>
3561	<li><link to="#id"/></li>
3562	<li><link to="#settingsFilePath"/></li>
3563	<li><link to="#accessible"/></li>
3564	<li><link to="#accessError"/></li>
3565	</ul>
3566
3567	An attempt to access any other property or method will return
3568	an error.

3570	The only possible action you can perform on an inaccessible
3571	machine is to unregister it using the
3572	<link to="IMachine::unregister"/> call (or, to check
3573	for the accessibility state once more by querying this
3574	property).
3575
3576	<note>
3577	In the current implementation, once this property returns
3578	@c true, the machine will never become inaccessible
3579	later, even if its settings file cannot be successfully
3580	read/written any more (at least, until the VirtualBox
3581	server is restarted). This limitation may be removed in

3601	Name of the virtual machine.
3602
3603	Besides being used for human-readable identification purposes
3604	everywhere in VirtualBox, the virtual machine name is also used
3605	as a name of the machine's settings file and as a name of the
3606	subdirectory this settings file resides in. Thus, every time you
3607	change the value of this property, the settings file will be
3608	renamed once you call <link to="#saveSettings"/> to confirm the
3609	change. The containing subdirectory will be also renamed, but
3610	only if it has exactly the same name as the settings file
3611	itself prior to changing this property (for backward compatibility
3612	with previous API releases). The above implies the following
3613	limitations:
3614	<ul>
3615	<li>The machine name cannot be empty.</li>
3616	<li>The machine name can contain only characters that are valid
3617	file name characters according to the rules of the file
3618	system used to store VirtualBox configuration.</li>
3619	<li>You cannot have two or more machines with the same name
3620	if they use the same subdirectory for storing the machine
3621	settings files.</li>
3622	<li>You cannot change the name of the machine if it is running,
3623	or if any file in the directory containing the settings file
3624	is being used by another running machine or by any other
3625	process in the host operating system at a time when
3626	<link to="#saveSettings"/> is called.
3627	</li>
3628	</ul>
3629	If any of the above limitations are hit, <link to="#saveSettings"/>
3630	will return an appropriate error message explaining the exact
3631	reason and the changes you made to this machine will not be saved.
3632
3633	Starting with VirtualBox 4.0, a “.vbox” extension of the settings

4108	<method name="lockMachine">
4109	<desc>
4110	Locks the machine for the given session to enable the caller
4111	to make changes to the machine or start the VM or control
4112	VM execution.
4113
4114	There are two ways to lock a machine for such uses:
4115
4116	<ul>
4117	<li>If you want to make changes to the machine settings,
4118	you must obtain an exclusive write lock on the machine
4119	by setting @a lockType to @c Write.
4120
4121	This will only succeed if no other process has locked
4122	the machine to prevent conflicting changes. Only after
4123	an exclusive write lock has been obtained using this method, one
4124	can change all VM settings or execute the VM in the process
4125	space of the session object. (Note that the latter is only of
4126	interest if you actually want to write a new front-end for
4127	virtual machines; but this API gets called internally by
4128	the existing front-ends such as VBoxHeadless and the VirtualBox
4129	GUI to acquire a write lock on the machine that they are running.)
4130
4131	On success, write-locking the machine for a session creates
4132	a second copy of the IMachine object. It is this second object
4133	upon which changes can be made; in VirtualBox terminology, the
4134	second copy is "mutable". It is only this second, mutable machine
4135	object upon which you can call methods that change the
4136	machine state. After having called this method, you can
4137	obtain this second, mutable machine object using the
4138	<link to="ISession::machine" /> attribute.
4139	</li>
4140	<li>If you only want to check the machine state or control
4141	machine execution without actually changing machine
4142	settings (e.g. to get access to VM statistics or take
4143	a snapshot or save the machine state), then set the
4144	@a lockType argument to @c Shared.
4145
4146	If no other session has obtained a lock, you will obtain an
4147	exclusive write lock as described above. However, if another
4148	session has already obtained such a lock, then a link to that
4149	existing session will be established which allows you
4150	to control that existing session.
4151
4152	To find out which type of lock was obtained, you can
4153	inspect <link to="ISession::type" />, which will have been
4154	set to either @c WriteLock or @c Shared.
4155	</li>
4156	</ul>
4157
4158	In either case, you can get access to the <link to="IConsole" />
4159	object which controls VM execution.
4160
4161	Also in all of the above cases, one must always call
4162	<link to="ISession::unlockMachine" /> to release the lock on the machine, or
4163	the machine's state will eventually be set to "Aborted".
4164
4165	To change settings on a machine, the following sequence is typically
4166	performed:
4167
4168	<ol>
4169	<li>Call this method to obtain an exclusive write lock for the current session.</li>
4170
4171	<li>Obtain a mutable IMachine object from <link to="ISession::machine" />.</li>
4172
4173	<li>Change the settings of the machine by invoking IMachine methods.</li>
4174
4175	<li>Call <link to="IMachine::saveSettings" />.</li>
4176
4177	<li>Release the write lock by calling <link to="ISession::unlockMachine"/>.</li>

4206
4207	<method name="launchVMProcess">
4208	<desc>
4209	Spawns a new process that will execute the virtual machine and obtains a shared
4210	lock on the machine for the calling session.
4211
4212	If launching the VM succeeds, the new VM process will create its own session
4213	and write-lock the machine for it, preventing conflicting changes from other
4214	processes. If the machine is already locked (because it is already running or
4215	because another session has a write lock), launching the VM process will therefore
4216	fail. Reversely, future attempts to obtain a write lock will also fail while the
4217	machine is running.
4218
4219	The caller's session object remains separate from the session opened by the new
4220	VM process. It receives its own <link to="IConsole" /> object which can be used
4221	to control machine execution, but it cannot be used to change all VM settings
4222	which would be available after a <link to="#lockMachine" /> call.
4223
4224	The caller must eventually release the session's shared lock by calling
4225	<link to="ISession::unlockMachine" /> on the local session object once this call
4226	has returned. However, the session's state (see <link to="ISession::state" />)
4227	will not return to "Unlocked" until the remote session has also unlocked
4228	the machine (i.e. the machine has stopped running).
4229
4230	Launching a VM process can take some time (a new VM is started in a new process,
4231	for which memory and other resources need to be set up). Because of this,
4232	an <link to="IProgress" /> object is returned to allow the caller to wait
4233	for this asynchronous operation to be completed. Until then, the caller's
4234	session object remains in the "Unlocked" state, and its <link to="ISession::machine" />
4235	and <link to="ISession::console" /> attributes cannot be accessed.
4236	It is recommended to use <link to="IProgress::waitForCompletion" /> or
4237	similar calls to wait for completion. Completion is signalled when the VM
4238	is powered on. If launching the VM fails, error messages can be queried
4239	via the progress object, if available.
4240
4241	The progress object will have at least 2 sub-operations. The first
4242	operation covers the period up to the new VM process calls powerUp.
4243	The subsequent operations mirror the <link to="IConsole::powerUp"/>
4244	progress object. Because <link to="IConsole::powerUp"/> may require
4245	some extra sub-operations, the <link to="IProgress::operationCount"/>
4246	may change at the completion of operation.
4247
4248	For details on the teleportation progress operation, see
4249	<link to="IConsole::powerUp"/>.
4250
4251	The @a environment argument is a string containing definitions of
4252	environment variables in the following format:
4253	@code
4254	NAME[=VALUE]\n
4255	NAME[=VALUE]\n
4256	...
4257	@endcode
4258	where <tt>\\n</tt> is the new line character. These environment
4259	variables will be appended to the environment of the VirtualBox server
4260	process. If an environment variable exists both in the server process
4261	and in this list, the value from this list takes precedence over the
4262	server's variable. If the value of the environment variable is
4263	omitted, this variable will be removed from the resulting environment.
4264	If the environment string is @c null or empty, the server environment
4265	is inherited by the started process as is.

4384	This method is intended for managing storage devices in general while a

4387	to a machine:
4388
4389	<ul>
4390	<li>For fixed and removable media, you can pass in a medium that was

4392	</li>
4393
4394	<li>Only for storage devices supporting removable media (such as

4396	indicate an empty drive or one of the medium objects listed
4397	in the <link to="IHost::DVDDrives" /> and <link to="IHost::floppyDrives"/>
4398	arrays to indicate a host drive.
4399	For removable devices, you can also use <link to="IMachine::mountMedium"/>
4400	to change the media while the machine is running.
4401	</li>
4402	</ul>
4403

4596	This method is intended only for managing removable media, where the

5220	Unregisters a machine previously registered with
5221	<link to="IVirtualBox::registerMachine"/> and optionally do additional
5222	cleanup before the machine is unregistered.
5223
5224	This method does not delete any files. It only changes the machine configuration and
5225	the list of registered machines in the VirtualBox object. To delete the files which
5226	belonged to the machine, including the XML file of the machine itself, call
5227	<link to="#delete"/>, optionally with the array of IMedium objects which was returned
5228	from this method.
5229
5230	How thoroughly this method cleans up the machine configuration before unregistering
5231	the machine depends on the @a cleanupMode argument.
5232
5233	<ul>
5234	<li>With "UnregisterOnly", the machine will only be unregistered, but no additional
5235	cleanup will be performed. The call will fail if the machine is in "Saved" state
5236	or has any snapshots or any media attached (see <link to="IMediumAttachment" />).
5237	It is the responsibility of the caller to delete all such configuration in this mode.
5238	In this mode, the API behaves like the former @c IVirtualBox::unregisterMachine() API
5239	which it replaces.</li>
5240	<li>With "DetachAllReturnNone", the call will succeed even if the machine is in "Saved"
5241	state or if it has snapshots or media attached. All media attached to the current machine
5242	state or in snapshots will be detached. No medium objects will be returned;
5243	all of the machine's media will remain open.</li>
5244	<li>With "DetachAllReturnHardDisksOnly", the call will behave like with "DetachAllReturnNone",
5245	except that all the hard disk medium objects which were detached from the machine will
5246	be returned as an array. This allows for quickly passing them to the <link to="#delete" />
5247	API for closing and deletion.</li>
5248	<li>With "Full", the call will behave like with "DetachAllReturnHardDisksOnly", except
5249	that all media will be returned in the array, including removable media like DVDs and
5250	floppies. This might be useful if the user wants to inspect in detail which media were
5251	attached to the machine. Be careful when passing the media array to <link to="#delete" />
5252	in that case because users will typically want to preserve ISO and RAW image files.</li>
5253	</ul>
5254
5255	A typical implementation will use "DetachAllReturnHardDisksOnly" and then pass the
5256	resulting IMedium array to <link to="#delete"/>. This way, the machine is completely
5257	deleted with all its saved states and hard disk images, but images for removable
5258	drives (such as ISO and RAW files) will remain on disk.
5259
5260	This API does not verify whether the media files returned in the array are still
5261	attached to other machines (i.e. shared between several machines). If such a shared
5262	image is passed to <link to="#delete" /> however, closing the image will fail there
5263	and the image will be silently skipped.
5264
5265	This API may, however, move media from this machine's media registry to other media
5266	registries (see <link to="IMedium" /> for details on media registries). For machines
5267	created with VirtualBox 4.0 or later, if media from this machine's media registry
5268	are also attached to another machine (shared attachments), each such medium will be
5269	moved to another machine's registry. This is because without this machine's media
5270	registry, the other machine cannot find its media any more and would become inaccessible.
5271
5272	This API implicitly calls <link to="#saveSettings"/> to save all current machine settings
5273	before unregistering it. It may also silently call saveSettings() on other machines
5274	if media are moved to other machines' media registries.
5275
5276	After successful method invocation, the <link to="IMachineRegisteredEvent"/> event
5277	is fired.
5278
5279	The call will fail if the machine is currently locked (see <link to="ISession" />).
5280
5281	<note>
5282	If the given machine is inaccessible (see <link to="#accessible"/>), it
5283	will be unregistered and fully uninitialized right afterwards. As a result,
5284	the returned machine object will be unusable and an attempt to call
5285	<b>any</b> method will return the "Object not ready" error.

5303	Deletes the files associated with this machine from disk. If medium objects are passed
5304	in with the @a aMedia argument, they are closed and, if closing was successful, their
5305	storage files are deleted as well. For convenience, this array of media files can be
5306	the same as the one returned from a previous <link to="#unregister" /> call.
5307
5308	This method must only be called on machines which are either write-locked (i.e. on instances
5309	returned by <link to="ISession::machine"/>) or on unregistered machines (i.e. not yet
5310	registered machines created by <link to="IVirtualBox::createMachine"/> or opened by
5311	<link to="IVirtualBox::openMachine"/>, or after having called <link to="#unregister"/>).
5312
5313	The following files will be deleted by this method:
5314	<ul>
5315	<li>If <link to="#unregister" /> had been previously called with a @a cleanupMode
5316	argument other than "UnregisterOnly", this will delete all saved state files that
5317	the machine had in use; possibly one if the machine was in "Saved" state and one
5318	for each online snapshot that the machine had.</li>
5319	<li>On each medium object passed in the @a aMedia array, this will call
5320	<link to="IMedium::close" />. If that succeeds, this will attempt to delete the
5321	medium's storage on disk. Since the close() call will fail if the medium is still
5322	in use, e.g. because it is still attached to a second machine; in that case the
5323	storage will not be deleted.</li>
5324	<li>Finally, the machine's own XML file will be deleted.</li>
5325	</ul>
5326
5327	Since deleting large disk image files can be a time-consuming I/O operation, this
5328	method operates asynchronously and returns an IProgress object to allow the caller
5329	to monitor the progress. There will be one sub-operation for each file that is
5330	being deleted (saved state or medium storage file).
5331
5332	<note>
5333	<link to="#settingsModified"/> will return @c true after this

6628	The execution state and settings of the associated machine stored in
6629	the snapshot will be deleted. The contents of all differencing media of
6630	this snapshot will be merged with the contents of their dependent child
6631	media to keep the medium chain valid (in other words, all changes
6632	represented by media being deleted will be propagated to their child
6633	medium). After that, this snapshot's differencing medium will be
6634	deleted. The parent of this snapshot will become a new parent for all
6635	its child snapshots.
6636
6637	If the deleted snapshot is the current one, its parent snapshot will
6638	become a new current snapshot. The current machine state is not directly

6645	snapshot will also implicitly call <link to="IMachine::saveSettings"/>

6648	Deleting a snapshot has the following preconditions:
6649
6650	<ul>
6651	<li>Child media of all normal media of the deleted snapshot
6652	must be accessible (see <link to="IMedium::state"/>) for this
6653	operation to succeed. In particular, this means that all virtual
6654	machines whose media are directly or indirectly based on the
6655	media of deleted snapshot must be powered off.</li>
6656
6657	<li>You cannot delete the snapshot if a medium attached to it has
6658	more than once child medium (differencing images) because otherwise
6659	merging would be impossible. This might be the case if there is
6660	more than one child snapshot or differencing images were created
6661	for other reason (e.g. implicitly because of multiple machine
6662	attachments).</li>
6663	</ul>
6664
6665

6668	"DeletingSnapshotPaused" while this operation is in progress.
6669
6670	<note>
6671	Merging medium contents can be very time and disk space
6672	consuming, if these media are big in size and have many
6673	children. However, if the snapshot being deleted is the last
6674	(head) snapshot on the branch, the operation will be rather

7466
7467	Starting with VirtualBox 4.0, by default, this attribute contains
7468	the full path of folder named "VirtualBox VMs" in the user's
7469	home directory, which depends on the host platform.
7470
7471	When setting this attribute, a full path must be specified.

7490
7491	Keep in mind that the medium format identifier
7492	(<link to="IMediumFormat::id"/>) used in other API calls like
7493	<link to="IVirtualBox::createHardDisk"/> to refer to a particular
7494	medium format is a case-insensitive string. This means that, for

7497	"VDI"
7498	"vdi"
7499	"VdI"</pre>
7500	refer to the same medium format.

7513	<desc>
7514	Identifier of the default medium format used by VirtualBox.
7515
7516	The medium format set by this attribute is used by VirtualBox
7517	when the medium format was not specified explicitly. One example is
7518	<link to="IVirtualBox::createHardDisk"/> with the empty
7519	format argument. A more complex example is implicit creation of
7520	differencing media when taking a snapshot of a virtual machine:
7521	this operation will try to use a format of the parent medium first
7522	and if this format does not support differencing media the default
7523	format specified by this argument will be used.
7524
7525	The list of supported medium formats may be obtained by the
7526	<link to="#mediumFormats"/> call. Note that the default medium
7527	format must have a capability to create differencing media;
7528	otherwise operations that create media implicitly may fail
7529	unexpectedly.
7530
7531	The initial value of this property is <tt>"VDI"</tt> in the current
7532	version of the VirtualBox product, but may change in the future.

7599	As opposed to <link to="ISystemProperties::VRDEAuthLibrary" />,

7604	no matter what user name and password are supplied.
7605
7606	The initial value of this property is <tt>"VBoxAuth"</tt>,
7607	meaning that the webservice will use the same authentication

8519	<desc>
8520	The IProgress interface is used to track and control
8521	asynchronous tasks within VirtualBox.
8522
8523	An instance of this is returned every time VirtualBox starts
8524	an asynchronous task (in other words, a separate thread) which
8525	continues to run after a method call returns. For example,
8526	<link to="IConsole::saveState" />, which saves the state of
8527	a running virtual machine, can take a long time to complete.
8528	To be able to display a progress bar, a user interface such as
8529	the VirtualBox graphical user interface can use the IProgress
8530	object returned by that method.
8531
8532	Note that IProgress is a "read-only" interface in the sense
8533	that only the VirtualBox internals behind the Main API can
8534	create and manipulate progress objects, whereas client code
8535	can only use the IProgress object to monitor a task's
8536	progress and, if <link to="#cancelable" /> is @c true,
8537	cancel the task by calling <link to="#cancel" />.
8538
8539	A task represented by IProgress consists of either one or
8540	several sub-operations that run sequentially, one by one (see
8541	<link to="#operation" /> and <link to="#operationCount" />).
8542	Every operation is identified by a number (starting from 0)
8543	and has a separate description.
8544
8545	You can find the individual percentage of completion of the current
8546	operation in <link to="#operationPercent" /> and the
8547	percentage of completion of the task as a whole
8548	in <link to="#percent" />.
8549
8550	Similarly, you can wait for the completion of a particular
8551	operation via <link to="#waitForOperationCompletion" /> or
8552	for the completion of the whole task via
8553	<link to="#waitForCompletion" />.

8586
8587	Even if a value is returned, the estimate will be unreliable
8588	for low progress values. It will become more reliable as the

8733	<interface
8734	name="ISnapshot" extends="$unknown"
8735	uuid="1a2d0551-58a4-4107-857e-ef414fc42ffc"
8736	wsmap="managed"
8737	>
8738	<desc>
8739	The ISnapshot interface represents a snapshot of the virtual
8740	machine.
8741
8742	Together with the differencing media that are created
8743	when a snapshot is taken, a machine can be brought back to
8744	the exact state it was in when the snapshot was taken.
8745
8746	The ISnapshot interface has no methods, only attributes; snapshots
8747	are controlled through methods of the <link to="IConsole" /> interface
8748	which also manage the media associated with the snapshot.
8749	The following operations exist:
8750
8751	<ul>
8752	<li><link to="IConsole::takeSnapshot"/> creates a new snapshot
8753	by creating new, empty differencing images for the machine's
8754	media and saving the VM settings and (if the VM is running)
8755	the current VM state in the snapshot.
8756
8757	The differencing images will then receive all data written to
8758	the machine's media, while their parent (base) images
8759	remain unmodified after the snapshot has been taken (see
8760	<link to="IMedium" /> for details about differencing images).
8761	This simplifies restoring a machine to the state of a snapshot:
8762	only the differencing images need to be deleted.
8763
8764	The current machine state is not changed by taking a snapshot
8765	except that <link to="IMachine::currentSnapshot" /> is set to
8766	the newly created snapshot, which is also added to the machine's
8767	snapshots tree.
8768	</li>
8769
8770	<li><link to="IConsole::restoreSnapshot"/> resets a machine to
8771	the state of a previous snapshot by deleting the differencing
8772	image of each of the machine's media and setting the machine's
8773	settings and state to the state that was saved in the snapshot (if any).
8774
8775	This destroys the machine's current state. After calling this,
8776	<link to="IMachine::currentSnapshot" /> points to the snapshot
8777	that was restored.
8778	</li>
8779
8780	<li><link to="IConsole::deleteSnapshot"/> deletes a snapshot
8781	without affecting the current machine state.
8782
8783	This does not change the current machine state, but instead frees the
8784	resources allocated when the snapshot was taken: the settings and machine
8785	state file are deleted (if any), and the snapshot's differencing image for
8786	each of the machine's media gets merged with its parent image.
8787
8788	Neither the current machine state nor other snapshots are affected
8789	by this operation, except that parent media will be modified
8790	to contain the disk data associated with the snapshot being deleted.
8791
8792	When deleting the current snapshot, the <link to="IMachine::currentSnapshot" />
8793	attribute is set to the current snapshot's parent or NULL if it
8794	has no parent. Otherwise the attribute is unchanged.
8795	</li>
8796	</ul>
8797
8798	Each snapshot contains a copy of virtual machine's settings (hardware
8799	configuration etc.). This copy is contained in an immutable (read-only)
8800	instance of <link to="IMachine" /> which is available from the snapshot's
8801	<link to="#machine" /> attribute. When restoring the snapshot, these
8802	settings are copied back to the original machine.
8803
8804	In addition, if the machine was running when the
8805	snapshot was taken (<link to="IMachine::state"/> is <link to="MachineState_Running"/>),
8806	the current VM state is saved in the snapshot (similarly to what happens
8807	when a VM's state is saved). The snapshot is then said to be <i>online</i>
8808	because when restoring it, the VM will be running.
8809
8810	If the machine was in <link to="MachineState_Saved">saved</link> saved,
8811	the snapshot receives a copy of the execution state file
8812	(<link to="IMachine::stateFilePath"/>).
8813
8814	Otherwise, if the machine was not running (<link to="MachineState_PoweredOff"/>
8815	or <link to="MachineState_Aborted"/>), the snapshot is <i>offline</i>;
8816	it then contains a so-called "zero execution state", representing a
8817	machine that is powered off.

9045	The IMediumAttachment interface links storage media to virtual machines.
9046	For each medium (<link to="IMedium"/>) which has been attached to a
9047	storage controller (<link to="IStorageController"/>) of a machine
9048	(<link to="IMachine"/>) via the <link to="IMachine::attachDevice" />
9049	method, one instance of IMediumAttachment is added to the machine's
9050	<link to="IMachine::mediumAttachments"/> array attribute.
9051
9052	Each medium attachment specifies the storage controller as well as a
9053	port and device number and the IMedium instance representing a virtual
9054	hard disk or floppy or DVD image.
9055
9056	For removable media (DVDs or floppies), there are two additional
9057	options. For one, the IMedium instance can be @c null to represent
9058	an empty drive with no media inserted (see <link to="IMachine::mountMedium" />);
9059	secondly, the medium can be one of the pseudo-media for host drives
9060	listed in <link to="IHost::DVDDrives"/> or <link to="IHost::floppyDrives"/>.
9061
9062	<h3>Attaching Hard Disks</h3>
9063
9064	Hard disks are attached to virtual machines using the
9065	<link to="IMachine::attachDevice"/> method and detached using the
9066	<link to="IMachine::detachDevice"/> method. Depending on a medium's
9067	type (see <link to="IMedium::type" />), hard disks are attached either
9068	<i>directly</i> or <i>indirectly</i>.
9069
9070	When a hard disk is being attached directly, it is associated with the
9071	virtual machine and used for hard disk operations when the machine is
9072	running. When a hard disk is being attached indirectly, a new differencing
9073	hard disk linked to it is implicitly created and this differencing hard
9074	disk is associated with the machine and used for hard disk operations.
9075	This also means that if <link to="IMachine::attachDevice"/> performs
9076	a direct attachment then the same hard disk will be returned in response
9077	to the subsequent <link to="IMachine::getMedium"/> call; however if
9078	an indirect attachment is performed then
9079	<link to="IMachine::getMedium"/> will return the implicitly created
9080	differencing hard disk, not the original one passed to <link
9081	to="IMachine::attachDevice"/>. In detail:
9082
9083	<ul>
9084	<li><b>Normal base</b> hard disks that do not have children (i.e.
9085	differencing hard disks linked to them) and that are not already
9086	attached to virtual machines in snapshots are attached <b>directly</b>.
9087	Otherwise, they are attached <b>indirectly</b> because having
9088	dependent children or being part of the snapshot makes it impossible
9089	to modify hard disk contents without breaking the integrity of the
9090	dependent party. The <link to="IMedium::readOnly"/> attribute allows to
9091	quickly determine the kind of the attachment for the given hard
9092	disk. Note that if a normal base hard disk is to be indirectly
9093	attached to a virtual machine with snapshots then a special
9094	procedure called <i>smart attachment</i> is performed (see below).</li>
9095	<li><b>Normal differencing</b> hard disks are like normal base hard disks:
9096	they are attached <b>directly</b> if they do not have children and are
9097	not attached to virtual machines in snapshots, and <b>indirectly</b>
9098	otherwise. Note that the smart attachment procedure is never performed
9099	for differencing hard disks.</li>
9100	<li><b>Immutable</b> hard disks are always attached <b>indirectly</b> because
9101	they are designed to be non-writable. If an immutable hard disk is
9102	attached to a virtual machine with snapshots then a special
9103	procedure called smart attachment is performed (see below).</li>
9104	<li><b>Writethrough</b> hard disks are always attached <b>directly</b>,
9105	also as designed. This also means that writethrough hard disks cannot
9106	have other hard disks linked to them at all.</li>
9107	<li><b>Shareable</b> hard disks are always attached <b>directly</b>,
9108	also as designed. This also means that shareable hard disks cannot
9109	have other hard disks linked to them at all. They behave almost
9110	like writethrough hard disks, except that shareable hard disks can
9111	be attached to several virtual machines which are running, allowing
9112	concurrent accesses. You need special cluster software running in
9113	the virtual machines to make use of such disks.</li>
9114	</ul>
9115
9116	Note that the same hard disk, regardless of its type, may be attached to
9117	more than one virtual machine at a time. In this case, the machine that is
9118	started first gains exclusive access to the hard disk and attempts to
9119	start other machines having this hard disk attached will fail until the
9120	first machine is powered down.
9121
9122	Detaching hard disks is performed in a <i>deferred</i> fashion. This means
9123	that the given hard disk remains associated with the given machine after a
9124	successful <link to="IMachine::detachDevice"/> call until
9125	<link to="IMachine::saveSettings"/> is called to save all changes to
9126	machine settings to disk. This deferring is necessary to guarantee that
9127	the hard disk configuration may be restored at any time by a call to
9128	<link to="IMachine::discardSettings"/> before the settings
9129	are saved (committed).
9130
9131	Note that if <link to="IMachine::discardSettings"/> is called after
9132	indirectly attaching some hard disks to the machine but before a call to
9133	<link to="IMachine::saveSettings"/> is made, it will implicitly delete
9134	all differencing hard disks implicitly created by
9135	<link to="IMachine::attachDevice"/> for these indirect attachments.
9136	Such implicitly created hard disks will also be immediately deleted when
9137	detached explicitly using the <link to="IMachine::detachDevice"/>
9138	call if it is made before <link to="IMachine::saveSettings"/>. This
9139	implicit deletion is safe because newly created differencing hard
9140	disks do not contain any user data.
9141
9142	However, keep in mind that detaching differencing hard disks that were
9143	implicitly created by <link to="IMachine::attachDevice"/>
9144	before the last <link to="IMachine::saveSettings"/> call will
9145	<b>not</b> implicitly delete them as they may already contain some data
9146	(for example, as a result of virtual machine execution). If these hard
9147	disks are no more necessary, the caller can always delete them explicitly
9148	using <link to="IMedium::deleteStorage"/> after they are actually de-associated
9149	from this machine by the <link to="IMachine::saveSettings"/> call.
9150
9151	<h3>Smart Attachment</h3>
9152
9153	When normal base or immutable hard disks are indirectly attached to a
9154	virtual machine then some additional steps are performed to make sure the
9155	virtual machine will have the most recent "view" of the hard disk being
9156	attached. These steps include walking through the machine's snapshots
9157	starting from the current one and going through ancestors up to the first
9158	snapshot. Hard disks attached to the virtual machine in all
9159	of the encountered snapshots are checked whether they are descendants of
9160	the given normal base or immutable hard disk. The first found child (which
9161	is the differencing hard disk) will be used instead of the normal base or
9162	immutable hard disk as a parent for creating a new differencing hard disk
9163	that will be actually attached to the machine. And only if no descendants
9164	are found or if the virtual machine does not have any snapshots then the
9165	normal base or immutable hard disk will be used itself as a parent for
9166	this differencing hard disk.
9167
9168	It is easier to explain what smart attachment does using the
9169	following example:
9170	<pre>
9171	BEFORE attaching B.vdi: AFTER attaching B.vdi:
9172
9173	Snapshot 1 (B.vdi) Snapshot 1 (B.vdi)
9174	Snapshot 2 (D1->B.vdi) Snapshot 2 (D1->B.vdi)
9175	Snapshot 3 (D2->D1.vdi) Snapshot 3 (D2->D1.vdi)
9176	Snapshot 4 (none) Snapshot 4 (none)
9177	CurState (none) CurState (D3->D2.vdi)
9178
9179	NOT
9180	...
9181	CurState (D3->B.vdi)
9182	</pre>
9183	The first column is the virtual machine configuration before the base hard
9184	disk <tt>B.vdi</tt> is attached, the second column shows the machine after
9185	this hard disk is attached. Constructs like <tt>D1->B.vdi</tt> and similar
9186	mean that the hard disk that is actually attached to the machine is a
9187	differencing hard disk, <tt>D1.vdi</tt>, which is linked to (based on)
9188	another hard disk, <tt>B.vdi</tt>.
9189
9190	As we can see from the example, the hard disk <tt>B.vdi</tt> was detached
9191	from the machine before taking Snapshot 4. Later, after Snapshot 4 was
9192	taken, the user decides to attach <tt>B.vdi</tt> again. <tt>B.vdi</tt> has
9193	dependent child hard disks (<tt>D1.vdi</tt>, <tt>D2.vdi</tt>), therefore
9194	it cannot be attached directly and needs an indirect attachment (i.e.
9195	implicit creation of a new differencing hard disk). Due to the smart
9196	attachment procedure, the new differencing hard disk
9197	(<tt>D3.vdi</tt>) will be based on <tt>D2.vdi</tt>, not on
9198	<tt>B.vdi</tt> itself, since <tt>D2.vdi</tt> is the most recent view of
9199	<tt>B.vdi</tt> existing for this snapshot branch of the given virtual
9200	machine.
9201
9202	Note that if there is more than one descendant hard disk of the given base
9203	hard disk found in a snapshot, and there is an exact device, channel and
9204	bus match, then this exact match will be used. Otherwise, the youngest
9205	descendant will be picked up.
9206
9207	There is one more important aspect of the smart attachment procedure which
9208	is not related to snapshots at all. Before walking through the snapshots
9209	as described above, the backup copy of the current list of hard disk
9210	attachment is searched for descendants. This backup copy is created when
9211	the hard disk configuration is changed for the first time after the last
9212	<link to="IMachine::saveSettings"/> call and used by
9213	<link to="IMachine::discardSettings"/> to undo the recent hard disk
9214	changes. When such a descendant is found in this backup copy, it will be
9215	simply re-attached back, without creating a new differencing hard disk for
9216	it. This optimization is necessary to make it possible to re-attach the
9217	base or immutable hard disk to a different bus, channel or device slot
9218	without losing the contents of the differencing hard disk actually
9219	attached to the machine in place of it.

9266	The IMedium interface represents virtual storage for a machine's
9267	hard disks, CD/DVD or floppy drives. It will typically represent
9268	a disk image on the host, for example a VDI or VMDK file representing
9269	a virtual hard disk, or an ISO or RAW file representing virtual
9270	removable media, but can also point to a network location (e.g.
9271	for iSCSI targets).
9272
9273	Instances of IMedium are connected to virtual machines by way of medium
9274	attachments, which link the storage medium to a particular device slot
9275	of a storage controller of the virtual machine.
9276	In the VirtualBox API, virtual storage is therefore always represented
9277	by the following chain of object links:
9278
9279	<ul>
9280	<li><link to="IMachine::storageControllers"/> contains an array of
9281	storage controllers (IDE, SATA, SCSI, SAS or a floppy controller;
9282	these are instances of <link to="IStorageController"/>).</li>
9283	<li><link to="IMachine::mediumAttachments"/> contains an array of
9284	medium attachments (instances of <link to="IMediumAttachment"/>
9285	created by <link to="IMachine::attachDevice" />),
9286	each containing a storage controller from the above array, a
9287	port/device specification, and an instance of IMedium representing
9288	the medium storage (image file).
9289
9290	For removable media, the storage medium is optional; a medium
9291	attachment with no medium represents a CD/DVD or floppy drive
9292	with no medium inserted. By contrast, hard disk attachments
9293	will always have an IMedium object attached.</li>
9294	<li>Each IMedium in turn points to a storage unit (such as a file
9295	on the host computer or a network resource) that holds actual
9296	data. This location is represented by the <link to="#location"/>
9297	attribute.</li>
9298	</ul>
9299
9300	Existing media are opened using <link to="IVirtualBox::openMedium"/>;
9301	new hard disk media can be created with the VirtualBox API using the
9302	<link to="IVirtualBox::createHardDisk"/> method. Differencing hard
9303	disks (see below) are usually implicitly created by VirtualBox as
9304	needed, but may also be created explicitly using <link to="#createDiffStorage"/>.
9305	VirtualBox cannot create CD/DVD or floppy images (ISO and RAW files); these
9306	should be created with external tools and then opened from within VirtualBox.
9307
9308	Only for CD/DVDs and floppies, an IMedium instance can also represent a host
9309	drive. In that case the <link to="#id" /> attribute contains the UUID of
9310	one of the drives in <link to="IHost::DVDDrives" /> or <link to="IHost::floppyDrives" />.
9311
9312	<h3>Media registries</h3>
9313
9314	When a medium has been opened or created using one of the aforementioned
9315	APIs, it becomes "known" to VirtualBox. Known media can be attached
9316	to virtual machines and accessed through <link to="IVirtualBox::findMedium"/>.
9317	They also appear in the global
9318	<link to="IVirtualBox::hardDisks" />,
9319	<link to="IVirtualBox::DVDImages" /> and
9320	<link to="IVirtualBox::floppyImages" /> arrays.
9321
9322	Prior to VirtualBox 4.0, opening a medium added it to a global media registry
9323	in the VirtualBox.xml file, which was shared between all machines and made
9324	transporting machines and their media from one host to another difficult.
9325
9326	Starting with VirtualBox 4.0, media are only added to a registry when they are
9327	<i>attached</i> to a machine using <link to="IMachine::attachDevice" />. For
9328	backwards compatibility, which registry a medium is added to depends on which
9329	VirtualBox version created a machine:
9330
9331	<ul>
9332	<li>If the medium has first been attached to a machine which was created by
9333	VirtualBox 4.0 or later, it is added to that machine's media registry in
9334	the machine XML settings file. This way all information about a machine's
9335	media attachments is contained in a single file and can be transported
9336	easily.</li>
9337	<li>For older media attachments (i.e. if the medium was first attached to a
9338	machine which was created with a VirtualBox version before 4.0), media
9339	continue to be registered in the global VirtualBox settings file, for
9340	backwards compatibility.</li>
9341	</ul>
9342
9343	See <link to="IVirtualBox::openMedium" /> for more information.
9344
9345	Media are removed from media registries by the <link to="#close"/>,
9346	<link to="#deleteStorage"/> and <link to="#mergeTo"/> methods.
9347
9348	<h3>Accessibility checks</h3>
9349
9350	VirtualBox defers media accessibility checks until the <link to="#refreshState" />
9351	method is called explicitly on a medium. This is done to make the VirtualBox object
9352	ready for serving requests as fast as possible and let the end-user
9353	application decide if it needs to check media accessibility right away or not.
9354
9355	As a result, when VirtualBox starts up (e.g. the VirtualBox
9356	object gets created for the first time), all known media are in the
9357	"Inaccessible" state, but the value of the <link to="#lastAccessError"/>
9358	attribute is an empty string because no actual accessibility check has
9359	been made yet.
9360
9361	After calling <link to="#refreshState" />, a medium is considered
9362	<i>accessible</i> if its storage unit can be read. In that case, the
9363	<link to="#state"/> attribute has a value of "Created". If the storage
9364	unit cannot be read (for example, because it is located on a disconnected
9365	network resource, or was accidentally deleted outside VirtualBox),
9366	the medium is considered <i>inaccessible</i>, which is indicated by the
9367	"Inaccessible" state. The exact reason why the medium is inaccessible can be
9368	obtained by reading the <link to="#lastAccessError"/> attribute.
9369
9370	<h3>Medium types</h3>
9371
9372	There are five types of medium behavior which are stored in the
9373	<link to="#type"/> attribute (see <link to="MediumType" />) and
9374	which define the medium's behavior with attachments and snapshots.
9375
9376	All media can be also divided in two groups: <i>base</i> media and
9377	<i>differencing</i> media. A base medium contains all sectors of the
9378	medium data in its own storage and therefore can be used independently.
9379	In contrast, a differencing medium is a "delta" to some other medium and
9380	contains only those sectors which differ from that other medium, which is
9381	then called a <i>parent</i>. The differencing medium is said to be
9382	<i>linked to</i> that parent. The parent may be itself a differencing
9383	medium, thus forming a chain of linked media. The last element in that
9384	chain must always be a base medium. Note that several differencing
9385	media may be linked to the same parent medium.
9386
9387	Differencing media can be distinguished from base media by querying the
9388	<link to="#parent"/> attribute: base media do not have parents they would
9389	depend on, so the value of this attribute is always @c null for them.
9390	Using this attribute, it is possible to walk up the medium tree (from the
9391	child medium to its parent). It is also possible to walk down the tree
9392	using the <link to="#children"/> attribute.
9393
9394	Note that the type of all differencing media is "normal"; all other
9395	values are meaningless for them. Base media may be of any type.
9396
9397	<h3>Automatic composition of the file name part</h3>
9398
9399	Another extension to the <link to="IMedium::location"/> attribute is that
9400	there is a possibility to cause VirtualBox to compose a unique value for
9401	the file name part of the location using the UUID of the hard disk. This
9402	applies only to hard disks in <link to="MediumState_NotCreated"/> state,
9403	e.g. before the storage unit is created, and works as follows. You set the
9404	value of the <link to="IMedium::location"/> attribute to a location
9405	specification which only contains the path specification but not the file
9406	name part and ends with either a forward slash or a backslash character.
9407	In response, VirtualBox will generate a new UUID for the hard disk and
9408	compose the file name using the following pattern:
9409	<pre>
9410	<path>/{<uuid>}.<ext>
9411	</pre>
9412	where <tt><path></tt> is the supplied path specification,
9413	<tt><uuid></tt> is the newly generated UUID and <tt><ext></tt>
9414	is the default extension for the storage format of this hard disk. After
9415	that, you may call any of the methods that create a new hard disk storage
9416	unit and they will use the generated UUID and file name.
9417	</desc>
9418
9419	<attribute name="id" type="uuid" mod="string" readonly="yes">
9420	<desc>
9421	UUID of the medium. For a newly created medium, this value is a randomly
9422	generated UUID.
9423
9424	<note>
9425	For media in one of MediumState_NotCreated, MediumState_Creating or
9426	MediumState_Deleting states, the value of this property is undefined
9427	and will most likely be an empty UUID.

9431
9432	<attribute name="description" type="wstring">

9434	Optional description of the medium. For a newly created medium the value
9435	of this attribute is an empty string.
9436
9437	Medium types that don't support this attribute will return E_NOTIMPL in
9438	attempt to get or set this attribute's value.
9439
9440	<note>
9441	For some storage types, reading this attribute may return an outdated
9442	(last known) value when <link to="#state"/> is <link
9443	to="MediumState_Inaccessible"/> or <link
9444	to="MediumState_LockedWrite"/> because the value of this attribute is
9445	stored within the storage unit itself. Also note that changing the
9446	attribute value is not possible in such case, as well as when the
9447	medium is the <link to="MediumState_LockedRead"/> state.

9456	If that method has not yet been called on the medium, the state
9457	is "Inaccessible"; as opposed to truly inaccessible media, the
9458	value of <link to="#lastAccessError"/> will be an empty string in
9459	that case.
9460
9461	<note>As of version 3.1, this no longer performs an accessibility check

9475
9476	<attribute name="location" type="wstring">
9477	<desc>
9478	Location of the storage unit holding medium data.
9479
9480	The format of the location string is medium type specific. For medium
9481	types using regular files in a host's file system, the location
9482	string is the full file name.
9483
9484	Some medium types may support changing the storage unit location by
9485	simply changing the value of this property. If this operation is not
9486	supported, the implementation will return E_NOTIMPL in attempt to set
9487	this attribute's value.
9488
9489	When setting a value of the location attribute which is a regular file
9490	in the host's file system, the given file name may be either relative to
9491	the <link to="IVirtualBox::homeFolder">VirtualBox home folder</link> or
9492	absolute. Note that if the given location specification does not contain
9493	the file extension part then a proper default extension will be
9494	automatically appended by the implementation depending on the medium type.

9497
9498	<attribute name="name" type="wstring" readonly="yes">
9499	<desc>
9500	Name of the storage unit holding medium data.
9501
9502	The returned string is a short version of the <link to="#location"/>
9503	attribute that is suitable for representing the medium in situations
9504	where the full location specification is too long (such as lists
9505	and comboboxes in GUI frontends). This string is also used by frontends
9506	to sort the media list alphabetically when needed.
9507
9508	For example, for locations that are regular files in the host's file
9509	system, the value of this attribute is just the file name (+ extension),
9510	without the path specification.
9511
9512	Note that as opposed to the <link to="#location"/> attribute, the name
9513	attribute will not necessary be unique for a list of media of the

9776
9777	The refresh, if performed, may take a long time (several seconds or even

9832	<method name="lockRead">
9833	<desc>
9834	Locks this medium for reading.
9835
9836	A read lock is shared: many clients can simultaneously lock the
9837	same medium for reading unless it is already locked for writing (see
9838	<link to="#lockWrite"/>) in which case an error is returned.
9839
9840	When the medium is locked for reading, it cannot be modified
9841	from within VirtualBox. This means that any method that changes
9842	the properties of this medium or contents of the storage unit
9843	will return an error (unless explicitly stated otherwise). That
9844	includes an attempt to start a virtual machine that wants to
9845	write to the the medium.
9846
9847	When the virtual machine is started up, it locks for reading all
9848	media it uses in read-only mode. If some medium cannot be locked
9849	for reading, the startup procedure will fail.
9850	A medium is typically locked for reading while it is used by a running
9851	virtual machine but has a depending differencing image that receives
9852	the actual write operations. This way one base medium can have
9853	multiple child differencing images which can be written to
9854	simultaneously. Read-only media such as DVD and floppy images are
9855	also locked for reading only (so they can be in use by multiple
9856	machines simultaneously).
9857
9858	A medium is also locked for reading when it is the source of a
9859	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9860
9861	The medium locked for reading must be unlocked using the <link
9862	to="#unlockRead"/> method. Calls to <link to="#lockRead"/>
9863	can be nested and must be followed by the same number of paired
9864	<link to="#unlockRead"/> calls.
9865
9866	This method sets the medium state (see <link to="#state"/>) to
9867	"LockedRead" on success. The medium's previous state must be
9868	one of "Created", "Inaccessible" or "LockedRead".
9869
9870	Locking an inaccessible medium is not an error; this method performs
9871	a logical lock that prevents modifications of this medium through
9872	the VirtualBox API, not a physical file-system lock of the underlying
9873	storage unit.
9874
9875	This method returns the current state of the medium

9912	<method name="lockWrite">
9913	<desc>
9914	Locks this medium for writing.
9915
9916	A write lock, as opposed to <link to="#lockRead"/>, is
9917	exclusive: there may be only one client holding a write lock,
9918	and there may be no read locks while the write lock is held.
9919	As a result, read-locking fails if a write lock is held, and
9920	write-locking fails if either a read or another write lock is held.
9921
9922	When a medium is locked for writing, it cannot be modified
9923	from within VirtualBox, and it is not guaranteed that the values
9924	of its properties are up-to-date. Any method that changes the
9925	properties of this medium or contents of the storage unit will
9926	return an error (unless explicitly stated otherwise).
9927
9928	When a virtual machine is started up, it locks for writing all
9929	media it uses to write data to. If any medium could not be locked
9930	for writing, the startup procedure will fail. If a medium has
9931	differencing images, then while the machine is running, only
9932	the last ("leaf") differencing image is locked for writing,
9933	whereas its parents are locked for reading only.
9934
9935	A medium is also locked for writing when it is the target of a
9936	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9937
9938	The medium locked for writing must be unlocked using the <link

10283	above example, the result will be written to <tt>Diff_2</tt>; in case of
10284	the backward merge, the result will be written to <tt>Base</tt>. In
10285	other words, the result of the operation is always stored in the target
10286	medium.
10287
10288	Upon successful operation completion, the storage units of all media in
10289	the chain between this (source) medium and the target medium, including
10290	the source medium itself, will be automatically deleted and the
10291	relevant medium objects (including this medium) will become
10292	uninitialized. This means that any attempt to call any of
10293	their methods or attributes will fail with the
10294	<tt>"Object not ready" (E_ACCESSDENIED)</tt> error. Applied to the above
10295	example, the forward merge of <tt>Base</tt> to <tt>Diff_2</tt> will
10296	delete and uninitialize both <tt>Base</tt> and <tt>Diff_1</tt> media.
10297	Note that <tt>Diff_2</tt> in this case will become a base medium
10298	itself since it will no longer be based on any other medium.
10299
10300	Considering the above, all of the following conditions must be met in
10301	order for the merge operation to succeed:
10302	<ul>
10303	<li>
10304	Neither this (source) medium nor any intermediate
10305	differencing medium in the chain between it and the target
10306	medium is attached to any virtual machine.
10307	</li>
10308	<li>
10309	Neither the source medium nor the target medium is an
10310	<link to="MediumType_Immutable"/> medium.
10311	</li>
10312	<li>
10313	The part of the medium tree from the source medium to the
10314	target medium is a linear chain, i.e. all medium in this
10315	chain have exactly one child which is the next medium in this
10316	chain. The only exception from this rule is the target medium in
10317	the forward merge operation; it is allowed to have any number of
10318	child media because the merge operation will not change its
10319	logical contents (as it is seen by the guest OS or by children).
10320	</li>
10321	<li>
10322	None of the involved media are in
10323	<link to="MediumState_LockedRead"/> or
10324	<link to="MediumState_LockedWrite"/> state.
10325	</li>
10326	</ul>
10327
10328	<note>
10329	This (source) medium and all intermediates will be placed to <link
10330	to="MediumState_Deleting"/> state and the target medium will be
10331	placed to <link to="MediumState_LockedWrite"/> state and for the
10332	duration of this operation.

10347	Starts creating a clone of this medium in the format and at the

10349
10350	The target medium must be either in <link to="MediumState_NotCreated"/>

10352	<link to="MediumState_Created"/> state (i.e. created and not locked, and
10353	big enough to hold the data or else the copy will be partial). Upon
10354	successful completion, the cloned medium will contain exactly the
10355	same sector data as the medium being cloned, except that in the
10356	first case a new UUID for the clone will be randomly generated, and in
10357	the second case the UUID will remain unchanged.
10358
10359	The @a parent argument defines which medium will be the parent
10360	of the clone. Passing a @c null reference indicates that the clone will
10361	be a base image, i.e. completely independent. It is possible to specify
10362	an arbitrary medium for this parameter, including the parent of the
10363	medium which is being cloned. Even cloning to a child of the source
10364	medium is possible. Note that when cloning to an existing image, the

10427	does not make any assumptions about the medium contents.

10429	Resizing usually needs additional disk space, and possibly also
10430	some temporary disk space. Note that resize does not create a full

11110
11111	There are two modes of working with the video buffer of the virtual
11112	machine. The <i>indirect</i> mode implies that the IFramebuffer
11113	implementation allocates a memory buffer for the requested display mode
11114	and provides it to the virtual machine. In <i>direct</i> mode, the
11115	IFramebuffer implementation uses the memory buffer allocated and owned
11116	by the virtual machine. This buffer represents the video memory of the
11117	emulated video adapter (so called <i>guest VRAM</i>). The direct mode is
11118	usually faster because the implementation gets a raw pointer to the
11119	guest VRAM buffer which it can directly use for visualizing the contents
11120	of the virtual display, as opposed to the indirect mode where the
11121	contents of guest VRAM are copied to the memory buffer provided by
11122	the implementation every time a display update occurs.
11123
11124	It is important to note that the direct mode is really fast only when
11125	the implementation uses the given guest VRAM buffer directly, for
11126	example, by blitting it to the window representing the virtual machine's
11127	display, which saves at least one copy operation comparing to the
11128	indirect mode. However, using the guest VRAM buffer directly is not
11129	always possible: the format and the color depth of this buffer may be
11130	not supported by the target window, or it may be unknown (opaque) as in
11131	case of text or non-linear multi-plane VGA video modes. In this case,
11132	the indirect mode (that is always available) should be used as a
11133	fallback: when the guest VRAM contents are copied to the
11134	implementation-provided memory buffer, color and format conversion is
11135	done automatically by the underlying code.
11136
11137	The @a pixelFormat parameter defines whether the direct mode is
11138	available or not. If @a pixelFormat is <link
11139	to="FramebufferPixelFormat_Opaque"/> then direct access to the guest
11140	VRAM buffer is not available -- the @a VRAM, @a bitsPerPixel and
11141	@a bytesPerLine parameters must be ignored and the implementation must use
11142	the indirect mode (where it provides its own buffer in one of the
11143	supported formats). In all other cases, @a pixelFormat together with
11144	@a bitsPerPixel and @a bytesPerLine define the format of the video memory
11145	buffer pointed to by the @a VRAM parameter and the implementation is
11146	free to choose which mode to use. To indicate that this frame buffer uses
11147	the direct mode, the implementation of the <link to="#usesGuestVRAM"/>
11148	attribute must return @c true and <link to="#address"/> must
11149	return exactly the same address that is passed in the @a VRAM parameter
11150	of this method; otherwise it is assumed that the indirect strategy is
11151	chosen.
11152
11153	The @a width and @a height parameters represent the size of the
11154	requested display mode in both modes. In case of indirect mode, the
11155	provided memory buffer should be big enough to store data of the given
11156	display mode. In case of direct mode, it is guaranteed that the given
11157	@a VRAM buffer contains enough space to represent the display mode of the
11158	given size. Note that this frame buffer's <link to="#width"/> and <link
11159	to="#height"/> attributes must return exactly the same values as
11160	passed to this method after the resize is completed (see below).
11161
11162	The @a finished output parameter determines if the implementation has
11163	finished resizing the frame buffer or not. If, for some reason, the
11164	resize cannot be finished immediately during this call, @a finished
11165	must be set to @c false, and the implementation must call
11166	<link to="IDisplay::resizeCompleted"/> after it has returned from
11167	this method as soon as possible. If @a finished is @c false, the
11168	machine will not call any frame buffer methods until
11169	<link to="IDisplay::resizeCompleted"/> is called.
11170
11171	Note that if the direct mode is chosen, the <link to="#bitsPerPixel"/>,
11172	<link to="#bytesPerLine"/> and <link to="#pixelFormat"/> attributes of
11173	this frame buffer must return exactly the same values as specified in the
11174	parameters of this method, after the resize is completed. If the
11175	indirect mode is chosen, these attributes must return values describing
11176	the format of the implementation's own memory buffer <link
11177	to="#address"/> points to. Note also that the <link to="#bitsPerPixel"/>
11178	value must always correlate with <link to="#pixelFormat"/>. Note that
11179	the <link to="#pixelFormat"/> attribute must never return <link
11180	to="FramebufferPixelFormat_Opaque"/> regardless of the selected mode.
11181
11182	<note>
11183	This method is called by the IDisplay object under the
11184	<link to="#lock"/> provided by this IFramebuffer
11185	implementation. If this method returns @c false in @a finished, then

11889
11890	In host pipe mode, the #path attribute specifies the path to the pipe on
11891	the host computer that represents a serial port. The #server attribute
11892	determines if this pipe is created by the virtual machine process at
11893	machine startup or it must already exist before starting machine
11894	execution.
11895
11896	In host device mode, the #path attribute specifies the name of the
11897	serial port device on the host computer.
11898
11899	There is also a third communication mode: the disconnected mode. In this
11900	mode, the guest OS running inside the virtual machine will be able to
11901	detect the serial port, but all port write operations will be discarded

12714	<desc>
12715	The IUSBDeviceFilter interface represents an USB device filter used
12716	to perform actions on a group of USB devices.
12717
12718	This type of filters is used by running virtual machines to
12719	automatically capture selected USB devices once they are physically
12720	attached to the host computer.
12721
12722	A USB device is matched to the given device filter if and only if all
12723	attributes of the device match the corresponding attributes of the
12724	filter (that is, attributes are joined together using the logical AND
12725	operation). On the other hand, all together, filters in the list of
12726	filters carry the semantics of the logical OR operation. So if it is
12727	desirable to create a match like "this vendor id OR this product id",
12728	one needs to create two filters and specify "any match" (see below)
12729	for unused attributes.
12730
12731	All filter attributes used for matching are strings. Each string
12732	is an expression representing a set of values of the corresponding
12733	device attribute, that will match the given filter. Currently, the
12734	following filtering expressions are supported:
12735
12736	<ul>
12737	<li><i>Interval filters</i>. Used to specify valid intervals for
12738	integer device attributes (Vendor ID, Product ID and Revision).
12739	The format of the string is:
12740
12741	<tt>int:((m)\|([m]-[n]))(,(m)\|([m]-[n]))*</tt>
12742
12743	where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
12744	(starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
12745	or decimal (otherwise) form, so that <tt>m < n</tt>. If <tt>m</tt>
12746	is omitted before a dash (<tt>-</tt>), the minimum possible integer
12747	is assumed; if <tt>n</tt> is omitted after a dash, the maximum
12748	possible integer is assumed.
12749	</li>
12750	<li><i>Boolean filters</i>. Used to specify acceptable values for
12751	boolean device attributes. The format of the string is:
12752
12753	<tt>true\|false\|yes\|no\|0\|1</tt>
12754
12755	</li>
12756	<li><i>Exact match</i>. Used to specify a single value for the given
12757	device attribute. Any string that doesn't start with <tt>int:</tt>
12758	represents the exact match. String device attributes are compared to
12759	this string including case of symbols. Integer attributes are first
12760	converted to a string (see individual filter attributes) and then
12761	compared ignoring case.
12762
12763	</li>
12764	<li><i>Any match</i>. Any value of the corresponding device attribute
12765	will match the given filter. An empty or @c null string is
12766	used to construct this type of filtering expressions.
12767
12768	</li>
12769	</ul>
12770
12771	<note>
12772	On the Windows host platform, interval filters are not currently
12773	available. Also all string filter attributes
12774	(<link to="#manufacturer"/>, <link to="#product"/>,
12775	<link to="#serialNumber"/>) are ignored, so they behave as
12776	<i>any match</i> no matter what string expression is specified.

12884	USB device state. This enumeration represents all possible states
12885	of the USB device physically attached to the host computer regarding
12886	its state on the host computer and availability to guest computers
12887	(all currently running virtual machines).
12888
12889	Once a supported USB device is attached to the host, global USB
12890	filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
12891	either ignore the device, or put it to USBDeviceState_Held state, or do
12892	nothing. Unless the device is ignored by global filters, filters of all
12893	currently running guests (<link to="IUSBController::deviceFilters"/>) are
12894	activated that can put it to USBDeviceState_Captured state.
12895
12896	If the device was ignored by global filters, or didn't match
12897	any filters at all (including guest ones), it is handled by the host
12898	in a normal way. In this case, the device state is determined by
12899	the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
12900	or USBDeviceState_Available, depending on the current device usage.
12901
12902	Besides auto-capturing based on filters, the device can be manually
12903	captured by guests (<link to="IConsole::attachUSBDevice"/>) if its
12904	state is USBDeviceState_Busy, USBDeviceState_Available or
12905	USBDeviceState_Held.
12906
12907	<note>
12908	Due to differences in USB stack implementations in Linux and Win32,
12909	states USBDeviceState_Busy and USBDeviceState_Unavailable are applicable
12910	only to the Linux version of the product. This also means that (<link
12911	to="IConsole::attachUSBDevice"/>) can only succeed on Win32 if the
12912	device state is USBDeviceState_Held.

13240	<desc>
13241	The ISharedFolder interface represents a folder in the host computer's
13242	file system accessible from the guest OS running inside a virtual
13243	machine using an associated logical name.
13244
13245	There are three types of shared folders:
13246	<ul>
13247	<li><i>Global</i> (<link to="IVirtualBox::sharedFolders"/>), shared
13248	folders available to all virtual machines.</li>
13249	<li><i>Permanent</i> (<link to="IMachine::sharedFolders"/>),
13250	VM-specific shared folders available to the given virtual machine at
13251	startup.</li>
13252	<li><i>Transient</i> (<link to="IConsole::sharedFolders"/>),
13253	VM-specific shared folders created in the session context (for
13254	example, when the virtual machine is running) and automatically
13255	discarded when the session is closed (the VM is powered off).</li>
13256	</ul>
13257
13258	Logical names of shared folders must be unique within the given scope
13259	(global, permanent or transient). However, they do not need to be unique
13260	across scopes. In this case, the definition of the shared folder in a
13261	more specific scope takes precedence over definitions in all other
13262	scopes. The order of precedence is (more specific to more general):
13263	<ol>
13264	<li>Transient definitions</li>
13265	<li>Permanent definitions</li>
13266	<li>Global definitions</li>
13267	</ol>
13268
13269	For example, if MyMachine has a shared folder named
13270	<tt>C_DRIVE</tt> (that points to <tt>C:\\</tt>), then creating a
13271	transient shared folder named <tt>C_DRIVE</tt> (that points
13272	to <tt>C:\\\\WINDOWS</tt>) will change the definition
13273	of <tt>C_DRIVE</tt> in the guest OS so
13274	that <tt>\\\\VBOXSVR\\C_DRIVE</tt> will give access
13275	to <tt>C:\\WINDOWS</tt> instead of <tt>C:\\</tt> on the host

13778	The ISession interface represents a client process and allows for locking
13779	virtual machines (represented by IMachine objects) to prevent conflicting
13780	changes to the machine.
13781
13782	Any caller wishing to manipulate a virtual machine needs to create a session
13783	object first, which lives in its own process space. Such session objects are
13784	then associated with <link to="IMachine" /> objects living in the VirtualBox
13785	server process to coordinate such changes.
13786
13787	There are two typical scenarios in which sessions are used:
13788
13789	<ul>
13790	<li>To alter machine settings or control a running virtual machine, one
13791	needs to lock a machine for a given session (client process) by calling
13792	<link to="IMachine::lockMachine"/>.

13794	Whereas multiple sessions may control a running virtual machine, only
13795	one process can obtain a write lock on the machine to prevent conflicting
13796	changes. A write lock is also needed if a process wants to actually run a
13797	virtual machine in its own context, such as the VirtualBox GUI or
13798	VBoxHeadless front-ends. They must also lock a machine for their own
13799	sessions before they are allowed to power up the virtual machine.
13800
13801	As a result, no machine settings can be altered while another process is
13802	already using it, either because that process is modifying machine settings
13803	or because the machine is running.
13804	</li>
13805	<li>
13806	To start a VM using one of the existing VirtualBox front-ends (e.g. the
13807	VirtualBox GUI or VBoxHeadless), one would use
13808	<link to="IMachine::launchVMProcess"/>, which also takes a session object
13809	as its first parameter. This session then identifies the caller and lets the
13810	caller control the started machine (for example, pause machine execution or
13811	power it down) as well as be notified about machine execution state changes.
13812	</li>
13813	</ul>
13814
13815	How sessions objects are created in a client process depends on whether you use
13816	the Main API via COM or via the webservice:
13817
13818	<ul>
13819	<li>When using the COM API directly, an object of the Session class from the
13820	VirtualBox type library needs to be created. In regular COM C++ client code,
13821	this can be done by calling <tt>createLocalObject()</tt>, a standard COM API.
13822	This object will then act as a local session object in further calls to open
13823	a session.
13824	</li>
13825
13826	<li>In the webservice, the session manager (IWebsessionManager) instead creates
13827	a session object automatically whenever <link to="IWebsessionManager::logon" />
13828	is called. A managed object reference to that session object can be retrieved by
13829	calling <link to="IWebsessionManager::getSessionObject" />.

13859	for a particular session using the <link to="IMachine::launchVMProcess" />
13860	or <link to="IMachine::lockMachine" /> calls. Otherwise the state of
13861	the machine will be set to <link to="MachineState_Aborted" /> on the
13862	server, and changes made to the machine settings will be lost.
13863
13864	Generally, it is recommended to unlock all machines explicitly
13865	before terminating the application (regardless of the reason for
13866	the termination).
13867
13868	<note>
13869	Do not expect the session state (<link to="ISession::state" />

14284	<desc>
14285	The IPerformanceCollector interface represents a service that collects
14286	and stores performance metrics data.
14287
14288	Performance metrics are associated with objects of interfaces like IHost
14289	and IMachine. Each object has a distinct set of performance metrics. The
14290	set can be obtained with <link to="IPerformanceCollector::getMetrics"/>.
14291
14292	Metric data is collected at the specified intervals and is retained
14293	internally. The interval and the number of retained samples can be set
14294	with <link to="IPerformanceCollector::setupMetrics" />. Both metric data
14295	and collection settings are not persistent, they are discarded as soon as
14296	VBoxSVC process terminates. Moreover, metric settings and data associated
14297	with a particular VM only exist while VM is running. They disappear as
14298	soon as VM shuts down. It is not possible to set up metrics for machines
14299	that are powered off. One needs to start VM first, then set up metric
14300	collection parameters.
14301
14302	Metrics are organized hierarchically, with each level separated by a
14303	slash (/) character. Generally, the scheme for metric names is like this:
14304
14305	<tt>Category/Metric[/SubMetric][:aggregation]</tt>
14306
14307	"Category/Metric" together form the base metric name. A base metric is
14308	the smallest unit for which a sampling interval and the number of
14309	retained samples can be set. Only base metrics can be enabled and
14310	disabled. All sub-metrics are collected when their base metric is
14311	collected. Collected values for any set of sub-metrics can be queried
14312	with <link to="IPerformanceCollector::queryMetricsData" />.
14313
14314	For example "CPU/Load/User:avg" metric name stands for the "CPU"
14315	category, "Load" metric, "User" submetric, "average" aggregate. An
14316	aggregate function is computed over all retained data. Valid aggregate
14317	functions are:
14318
14319	<ul>
14320	<li>avg -- average</li>
14321	<li>min -- minimum</li>
14322	<li>max -- maximum</li>
14323	</ul>
14324
14325	When setting up metric parameters, querying metric data, enabling or
14326	disabling metrics wildcards can be used in metric names to specify a
14327	subset of metrics. For example, to select all CPU-related metrics
14328	use <tt>CPU/</tt>, all averages can be queried using <tt>:avg</tt> and
14329	so on. To query metric values without aggregates <tt>*:</tt> can be used.
14330
14331	The valid names for base metrics are:
14332
14333	<ul>
14334	<li>CPU/Load</li>
14335	<li>CPU/MHz</li>
14336	<li>RAM/Usage</li>
14337	</ul>
14338
14339	The general sequence for collecting and retrieving the metrics is:
14340	<ul>
14341	<li>
14342	Obtain an instance of IPerformanceCollector with
14343	<link to="IVirtualBox::performanceCollector" />
14344	</li>
14345	<li>
14346	Allocate and populate an array with references to objects the metrics
14347	will be collected for. Use references to IHost and IMachine objects.
14348	</li>
14349	<li>
14350	Allocate and populate an array with base metric names the data will
14351	be collected for.
14352	</li>
14353	<li>
14354	Call <link to="IPerformanceCollector::setupMetrics" />. From now on
14355	the metric data will be collected and stored.
14356	</li>
14357	<li>
14358	Wait for the data to get collected.
14359	</li>
14360	<li>
14361	Allocate and populate an array with references to objects the metric
14362	values will be queried for. You can re-use the object array used for
14363	setting base metrics.
14364	</li>
14365	<li>
14366	Allocate and populate an array with metric names the data will be
14367	collected for. Note that metric names differ from base metric names.
14368	</li>
14369	<li>
14370	Call <link to="IPerformanceCollector::queryMetricsData" />. The data
14371	that have been collected so far are returned. Note that the values
14372	are still retained internally and data collection continues.
14373	</li>
14374	</ul>

15667	Abstract parent interface for VirtualBox events. Actual events will typically implement
15668	a more specific interface which derives from this (see below).
15669
15670	<b>Introduction to VirtualBox events</b>
15671
15672	Generally speaking, an event (represented by this interface) signals that something
15673	happened, while an event listener (see <link to="IEventListener" />) represents an
15674	entity that is interested in certain events. In order for this to work with
15675	unidirectional protocols (i.e. web services), the concepts of passive and active
15676	listener are used.
15677
15678	Event consumers can register themselves as listeners, providing an array of
15679	events they are interested in (see <link to="IEventSource::registerListener" />).
15680	When an event triggers, the listener is notified about the event. The exact
15681	mechanism of the notification depends on whether the listener was registered as
15682	an active or passive listener:
15683
15684	<ul>
15685	<li>An active listener is very similar to a callback: it is a function invoked
15686	by the API. As opposed to the callbacks that were used in the API before
15687	VirtualBox 4.0 however, events are now objects with an interface hierarchy.
15688	</li>
15689
15690	<li>Passive listeners are somewhat trickier to implement, but do not require
15691	a client function to be callable, which is not an option with scripting
15692	languages or web service clients. Internally the <link to="IEventSource" />
15693	implementation maintains an event queue for each passive listener, and
15694	newly arrived events are put in this queue. When the listener calls
15695	<link to="IEventSource::getEvent"/>, first element from its internal event
15696	queue is returned. When the client completes processing of an event,
15697	the <link to="IEventSource::eventProcessed" /> function must be called,
15698	acknowledging that the event was processed. It supports implementing
15699	waitable events. On passive listener unregistration, all events from its
15700	queue are auto-acknowledged.
15701	</li>
15702	</ul>
15703
15704	Waitable events are useful in situations where the event generator wants to track
15705	delivery or a party wants to wait until all listeners have completed the event. A
15706	typical example would be a vetoable event (see <link to="IVetoEvent" />) where a
15707	listeners might veto a certain action, and thus the event producer has to make
15708	sure that all listeners have processed the event and not vetoed before taking
15709	the action.
15710
15711	A given event may have both passive and active listeners at the same time.
15712
15713	<b>Using events</b>
15714
15715	Any VirtualBox object capable of producing externally visible events provides an
15716	@c eventSource read-only attribute, which is of the type <link to="IEventSource" />.
15717	This event source object is notified by VirtualBox once something has happened, so
15718	consumers may register event listeners with this event source. To register a listener,
15719	an object implementing the <link to="IEventListener" /> interface must be provided.
15720	For active listeners, such an object is typically created by the consumer, while for
15721	passive listeners <link to="IEventSource::createListener" /> should be used. Please
15722	note that a listener created with @c createListener() must not be used as an active listener.
15723
15724	Once created, the listener must be registered to listen for the desired events
15725	(see <link to="IEventSource::registerListener" />), providing an array of
15726	<link to="VBoxEventType" /> enums. Those elements can either be the individual
15727	event IDs or wildcards matching multiple event IDs.
15728
15729	After registration, the callback's <link to="IEventListener::handleEvent" /> method is
15730	called automatically when the event is triggered, while passive listeners have to call
15731	<link to="IEventSource::getEvent" /> and <link to="IEventSource::eventProcessed" /> in
15732	an event processing loop.
15733
15734	The IEvent interface is an abstract parent interface for all such VirtualBox events
15735	coming in. As a result, the standard use pattern inside <link to="IEventListener::handleEvent" />
15736	or the event processing loop is to check the <link to="#type" /> attribute of the event and
15737	then cast to the appropriate specific interface using @c QueryInterface().

16427	<desc>
16428	Notification when an error happens during the virtual
16429	machine execution.
16430
16431	There are three kinds of runtime errors:
16432	<ul>
16433	<li><i>fatal</i></li>
16434	<li><i>non-fatal with retry</i></li>
16435	<li><i>non-fatal warnings</i></li>
16436	</ul>
16437
16438	<b>Fatal</b> errors are indicated by the @a fatal parameter set
16439	to @c true. In case of fatal errors, the virtual machine
16440	execution is always paused before calling this notification, and
16441	the notification handler is supposed either to immediately save
16442	the virtual machine state using <link to="IConsole::saveState"/>
16443	or power it off using <link to="IConsole::powerDown"/>.
16444	Resuming the execution can lead to unpredictable results.
16445
16446	<b>Non-fatal</b> errors and warnings are indicated by the
16447	@a fatal parameter set to @c false. If the virtual machine
16448	is in the Paused state by the time the error notification is
16449	received, it means that the user can <i>try to resume</i> the machine
16450	execution after attempting to solve the problem that caused the
16451	error. In this case, the notification handler is supposed
16452	to show an appropriate message to the user (depending on the
16453	value of the @a id parameter) that offers several actions such
16454	as <i>Retry</i>, <i>Save</i> or <i>Power Off</i>. If the user
16455	wants to retry, the notification handler should continue
16456	the machine execution using the <link to="IConsole::resume"/>
16457	call. If the machine execution is not Paused during this
16458	notification, then it means this notification is a <i>warning</i>
16459	(for example, about a fatal condition that can happen very soon);
16460	no immediate action is required from the user, the machine
16461	continues its normal execution.
16462
16463	Note that in either case the notification handler
16464	<b>must not</b> perform any action directly on a thread
16465	where this notification is called. Everything it is allowed to
16466	do is to post a message to another thread that will then talk
16467	to the user and take the corresponding action.
16468
16469	Currently, the following error identifiers are known:
16470	<ul>
16471	<li><tt>"HostMemoryLow"</tt></li>
16472	<li><tt>"HostAudioNotResponding"</tt></li>
