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

238	<desc>
239	This section describes all VirtualBox-specific COM result codes that may
240	be returned by methods of VirtualBox COM interfaces in addition to
241	standard COM result codes.
242
243	Note that along with the result code, every VirtualBox method returns
244	extended error information through the IVirtualBoxErrorInfo interface on
245	failure. This interface is a preferred way to present the error to the end
246	user because it contains a human readable description of the error. Raw
247	result codes, both standard and described in this section, are intended to
248	be used by programs to analyze the reason of a failure and select an
249	appropriate course of action without involving the end user (for example,
250	retry the operation later or make a different call).
251
252	The standard COM result codes that may originate from our methods include:
253
254	<table>
255	<tr><td>E_INVALIDARG</td>
256	<td>
257	Returned when the value of the method's argument is not within the range
258	of valid values. This should not be confused with situations when the
259	value is within the range but simply doesn't suit the current object
260	state and there is a possibility that it will be accepted later (in such
261	cases VirtualBox-specific codes are returned, for example,
262	<link to="VBOX_E_OBJECT_NOT_FOUND"/>).
263	</td>
264	</tr>
265	<tr><td>E_POINTER</td>
266	<td>
267	Returned if a memory pointer for the output argument is invalid (for
268	example, @c null). Note that when pointers representing input
269	arguments (such as strings) are invalid, E_INVALIDARG is returned.
270	</td>
271	</tr>
272	<tr><td>E_ACCESSDENIED</td>
273	<td>
274	Returned when the called object is not ready. Since the lifetime of a
275	public COM object cannot be fully controlled by the implementation,
276	VirtualBox maintains the readiness state for all objects it creates and
277	returns this code in response to any method call on the object that was
278	deactivated by VirtualBox and is not functioning any more.
279	</td>
280	</tr>
281	<tr><td>E_OUTOFMEMORY</td>
282	<td>
283	Returned when a memory allocation operation fails.

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

501	\| +-------- Saving <--------[saveState()]<----------+---------------------+
502	\| \| \|
503	+-------------- Stopping -------[powerDown()]<----------+---------------------+
504	</pre>
505
506	Note that states to the right from PoweredOff, Aborted and Saved in the
507	above diagram are called <i>online VM states</i>. These states
508	represent the virtual machine which is being executed in a dedicated
509	process (usually with a GUI window attached to it where you can see the
510	activity of the virtual machine and interact with it). There are two
511	special pseudo-states, FirstOnline and LastOnline, that can be used in
512	relational expressions to detect if the given machine state is online or
513	not:
514
515	<pre>
516	if (machine.GetState() >= MachineState_FirstOnline &&
517	machine.GetState() <= MachineState_LastOnline)
518	{
519	...the machine is being executed...
520	}
521	</pre>
522
523	When the virtual machine is in one of the online VM states (that is, being
524	executed), only a few machine settings can be modified. Methods working
525	with such settings contain an explicit note about that. An attempt to
526	change any oter setting or perform a modifying operation during this time
527	will result in the <link to="VBOX_E_INVALID_VM_STATE"/> error.
528
529	All online states except Running, Paused and Stuck are transitional: they
530	represent temporary conditions of the virtual machine that will last as
531	long as the operation that initiated such a condition.
532
533	The Stuck state is a special case. It means that execution of the machine
534	has reached the "Guru Meditation" condition. This condition indicates an
535	internal VMM (virtual machine manager) failure which may happen as a
536	result of either an unhandled low-level virtual hardware exception or one
537	of the recompiler exceptions (such as the <i>too-many-traps</i>
538	condition).
539
540	Note also that any online VM state may transit to the Aborted state. This
541	happens if the process that is executing the virtual machine terminates
542	unexpectedly (for example, crashes). Other than that, the Aborted state is
543	equivalent to PoweredOff.
544
545	There are also a few additional state diagrams that do not deal with
546	virtual machine execution and therefore are shown separately. The states
547	shown on these diagrams are called <i>offline VM states</i> (this includes
548	PoweredOff, Aborted and Saved too).
549
550	The first diagram shows what happens when a lengthy setup operation is
551	being executed (such as <link to="IMachine::attachDevice"/>).
552
553	<pre>
554	+----------------------------------(same state as before the call)------+
555	\| \|
556	+-> PoweredOff --+ \|
557	\| \| \|
558	\|-> Aborted -----+-->[lengthy VM configuration call] --> SettingUp -----+
559	\| \|
560	+-> Saved -------+
561	</pre>
562
563	The next two diagrams demonstrate the process of taking a snapshot of a
564	powered off virtual machine and performing one of the "discard..."
565	operations, respectively.
566
567	<pre>
568	+----------------------------------(same state as before the call)------+
569	\| \|
570	+-> PoweredOff --+ \|
571	\| +-->[takeSnapshot()] -------------------> Saving ------+
572	+-> Aborted -----+
573
574	+-> PoweredOff --+
575	\| \|
576	\| Aborted -----+-->[restoreSnapshot() ]-------> RestoringSnapshot -+
577	\| \| [deleteSnapshot() ]-------> DeletingSnapshot --+
578	+-> Saved -------+ \|
579	\| \|
580	+---(Saved if restored from an online snapshot, PoweredOff otherwise)---+
581	</pre>
582
583	Note that the Saving state is present in both the offline state group and
584	online state group. Currently, the only way to determine what group is
585	assumed in a particular case is to remember the previous machine state: if
586	it was Running or Paused, then Saving is an online state, otherwise it is
587	an offline state. This inconsistency may be removed in one of the future
588	versions of VirtualBox by adding a new state.
589
590	<note internal="yes">
591	For whoever decides to touch this enum: In order to keep the
592	comparisons involving FirstOnline and LastOnline pseudo-states valid,
593	the numeric values of these states must be correspondingly updated if
594	needed: for any online VM state, the condition
595	<tt>FirstOnline <= state <= LastOnline</tt> must be
596	@c true. The same relates to transient states for which
597	the condition <tt>FirstOnline <= state <= LastOnline</tt> must be
598	@c true.

1081	name="IVirtualBoxErrorInfo" extends="$errorinfo"
1082	uuid="4b86d186-407e-4f9e-8be8-e50061be8725"

1085	>
1086	<desc>
1087	The IVirtualBoxErrorInfo interface represents extended error information.
1088
1089	Extended error information can be set by VirtualBox components after
1090	unsuccessful or partially successful method invocation. This information
1091	can be retrieved by the calling party as an IVirtualBoxErrorInfo object
1092	and then shown to the client in addition to the plain 32-bit result code.
1093
1094	In MS COM, this interface extends the IErrorInfo interface,
1095	in XPCOM, it extends the nsIException interface. In both cases,
1096	it provides a set of common attributes to retrieve error
1097	information.
1098
1099	Sometimes invocation of some component's method may involve methods of
1100	other components that may also fail (independently of this method's
1101	failure), or a series of non-fatal errors may precede a fatal error that
1102	causes method failure. In cases like that, it may be desirable to preserve
1103	information about all errors happened during method invocation and deliver
1104	it to the caller. The <link to="#next"/> attribute is intended
1105	specifically for this purpose and allows to represent a chain of errors
1106	through a single IVirtualBoxErrorInfo object set after method invocation.
1107
1108	Note that errors are stored to a chain in the reverse order, i.e. the
1109	initial error object you query right after method invocation is the last
1110	error set by the callee, the object it points to in the @a next attribute
1111	is the previous error and so on, up to the first error (which is the last
1112	in the chain).

1114
1115	<attribute name="resultCode" type="long" readonly="yes">
1116	<desc>
1117	Result code of the error.
1118	Usually, it will be the same as the result code returned
1119	by the method that provided this error information, but not
1120	always. For example, on Win32, CoCreateInstance() will most
1121	likely return E_NOINTERFACE upon unsuccessful component
1122	instantiation attempt, but not the value the component factory
1123	returned. Value is typed 'long', not 'result',
1124	to make interface usable from scripting languages.

1684	<method name="createMachine">
1685	<desc>
1686	Creates a new virtual machine.
1687
1688	The new machine is created unregistered, with the initial configuration
1689	set according to the specified guest OS type. A typical sequence of
1690	actions to create a new virtual machine is as follows:
1691
1692	<ol>
1693	<li>
1694	Call this method to have a new machine created. The returned machine
1695	object will be "mutable" allowing to change any machine property.
1696	</li>
1697
1698	<li>
1699	Configure the machine using the appropriate attributes and methods.
1700	</li>
1701
1702	<li>
1703	Call <link to="IMachine::saveSettings" /> to write the settings
1704	to the machine's XML settings file. The configuration of the newly
1705	created machine will not be saved to disk until this method is
1706	called.
1707	</li>
1708
1709	<li>
1710	Call <link to="#registerMachine" /> to add the machine to the list
1711	of machines known to VirtualBox.
1712	</li>
1713	</ol>
1714
1715	You should specify valid name for the newly created machine when calling
1716	this method. See the <link to="IMachine::name"/> attribute description
1717	for more details about the machine name.
1718
1719	The specified guest OS type identifier must match an ID of one of known
1720	guest OS types listed in the <link to="IVirtualBox::guestOSTypes"/>
1721	array.
1722
1723	Every machine has a <i>settings file</i> that is used to store
1724	the machine configuration. This file is stored in a directory called the
1725	<i>machine settings subfolder</i>. Both the settings subfolder and file
1726	will have a name that corresponds to the name of the virtual machine.
1727	You can specify where to create the machine setting subfolder using the
1728	@a baseFolder argument. The base folder can be absolute (full path) or
1729	relative to the <link to="IVirtualBox::homeFolder">VirtualBox home
1730	directory</link>.
1731
1732	If @a baseFolder is a @c null or empty string (which is recommended), the
1733	<link to="ISystemProperties::defaultMachineFolder">default machine
1734	settings folder</link> will be used as a base folder for the created
1735	machine. Otherwise the given base folder will be used. In either case,
1736	the full path to the resulting settings file has the following
1737	structure:
1738	<pre>
1739	<base_folder>/<machine_name>/<machine_name>.xml
1740	</pre>
1741
1742	Note that if the resulting settings file already exists, this method
1743	will fail with <link to="VBOX_E_FILE_ERROR"/>.
1744
1745	Optionally, you may specify an UUID of to assign to the created machine.
1746	However, this is not recommended and you should normally pass an empty
1747	(@c null) UUID to this method so that a new UUID will be automatically
1748	generated for every created machine. You can use UUID
1749	00000000-0000-0000-0000-000000000000 as @c null value.
1750
1751	<note>
1752	There is no way to change the name of the settings file or
1753	subfolder of the created machine directly.

2527	<method name="openSession">
2528	<desc>
2529	Opens a new direct session with the given virtual machine.
2530
2531	A direct session acts as a local lock on the given VM.
2532	There can be only one direct session open at a time for every
2533	virtual machine, protecting the VM from being manipulated by
2534	conflicting actions from different processes. Only after a
2535	direct session has been opened, one can change all VM settings
2536	and execute the VM in the process space of the session object.
2537
2538	Sessions therefore can be compared to mutex semaphores that
2539	lock a given VM for modification and execution.
2540	See <link to="ISession">ISession</link> for details.
2541
2542	<note>Unless you are writing a new VM frontend, you will not
2543	want to execute a VM in the current process. To spawn a new
2544	process that executes a VM, use
2545	<link to="IVirtualBox::openRemoteSession" />
2546	instead.</note>
2547
2548	Upon successful return, the session object can be used to
2549	get access to the machine and to the VM console.
2550
2551	In VirtualBox terminology, the machine becomes "mutable" after
2552	a session has been opened. Note that the "mutable" machine
2553	object, on which you may invoke IMachine methods to change its
2554	settings, will be a different object from the immutable IMachine
2555	objects returned by various IVirtualBox methods. To obtain a
2556	mutable IMachine object (upon which you can invoke settings methods),
2557	use the <link to="ISession::machine" /> attribute.
2558
2559	One must always call <link to="ISession::close" /> to release the
2560	lock on the machine, or the machine's state will eventually be
2561	set to "Aborted".
2562
2563	In other words, to change settings on a machine, the following
2564	sequence is typically performed:
2565
2566	<ol>
2567	<li>Call this method (openSession) to have a machine locked for
2568	the current session.</li>
2569

2571
2572	<li>Change the settings of the machine.</li>

2612	<method name="openRemoteSession">
2613	<desc>
2614	Spawns a new process that executes a virtual machine (called a
2615	"remote session").
2616
2617	Opening a remote session causes the VirtualBox server to start a new
2618	process that opens a direct session with the given VM. As a result, the
2619	VM is locked by that direct session in the new process, preventing
2620	conflicting changes from other processes. Since sessions act as locks
2621	that prevent conflicting changes, one cannot open a remote session
2622	for a VM that already has another open session (direct or remote), or
2623	is currently in the process of opening one (see <link
2624	to="IMachine::sessionState"/>).
2625
2626	While the remote session still provides some level of control over the
2627	VM execution to the caller (using the <link to="IConsole" /> interface),
2628	not all VM settings are available for modification within the remote
2629	session context.
2630
2631	This operation can take some time (a new VM is started in a new process,
2632	for which memory and other resources need to be set up). Because of this,
2633	an <link to="IProgress" /> is returned to allow the caller to wait for this
2634	asynchronous operation to be completed. Until then, the remote session
2635	object remains in the closed state, and accessing the machine or its
2636	console through it is invalid. It is recommended to use
2637	<link to="IProgress::waitForCompletion" /> or similar calls to wait for
2638	completion.
2639
2640	As with all <link to="ISession" /> objects, it is recommended to call
2641	<link to="ISession::close" /> on the local session object once openRemoteSession()
2642	has been called. However, the session's state (see <link to="ISession::state" />)
2643	will not return to "Closed" until the remote session has also closed (i.e.
2644	until the VM is no longer running). In that case, however, the state of
2645	the session will automatically change back to "Closed".
2646
2647	Currently supported session types (values of the @a type
2648	argument) are:
2649	<ul>
2650	<li><tt>"gui"</tt>: VirtualBox Qt GUI session</li>
2651	<li><tt>"vrdp"</tt>: VirtualBox VRDP Server session</li>
2652	<li><tt>"sdl"</tt>: VirtualBox SDL GUI session</li>
2653	</ul>
2654
2655	The @a environment argument is a string containing definitions of
2656	environment variables in the following format:
2657	@code
2658	NAME[=VALUE]\n
2659	NAME[=VALUE]\n
2660	...
2661	@endcode
2662	where <tt>\\n</tt> is the new line character. These environment
2663	variables will be appended to the environment of the VirtualBox server
2664	process. If an environment variable exists both in the server process
2665	and in this list, the value from this list takes precedence over the
2666	server's variable. If the value of the environment variable is
2667	omitted, this variable will be removed from the resulting environment.
2668	If the environment string is @c null or empty, the server environment
2669	is inherited by the started process as is.

2802	<desc>
2803	Blocks the caller until any of the properties represented by the
2804	@a what argument changes the value or until the given timeout interval
2805	expires.
2806
2807	The @a what argument is a comma separated list of property masks that
2808	describe properties the caller is interested in. The property mask is
2809	a string in the following format:
2810
2811	<pre>
2812	[[group.]subgroup.]name
2813	</pre>
2814
2815	where @c name is the property name and @c group, @c subgroup are zero
2816	or more property group specifiers. Each element (group or name) in
2817	the property mask may be either a Latin string or an asterisk symbol
2818	(@c "*") which is used to match any string for the given element. A
2819	property mask that doesn't contain asterisk symbols represents a
2820	single fully qualified property name.
2821
2822	Groups in the fully qualified property name go from more generic (the
2823	left-most part) to more specific (the right-most part). The first
2824	element is usually a name of the object the property belongs to. The
2825	second element may be either a property name, or a child object name,
2826	or an index if the preceding element names an object which is one of
2827	many objects of the same type. This way, property names form a
2828	hierarchy of properties. Here are some examples of property names:
2829
2830	<table>
2831	<tr>
2832	<td><tt>VirtualBox.version</tt></td>
2833	<td><link to="IVirtualBox::version"/> property</td>
2834	</tr>
2835	<tr>
2836	<td><tt>Machine.<UUID>.name</tt></td>
2837	<td><link to="IMachine::name"/> property of the machine with the
2838	given UUID</td>
2839	</tr>
2840	</table>
2841
2842	Most property names directly correspond to the properties of objects
2843	(components) provided by the VirtualBox library and may be used to
2844	track changes to these properties. However, there may be
2845	pseudo-property names that don't correspond to any existing object's
2846	property directly, as well as there may be object properties that
2847	don't have a corresponding property name that is understood by this
2848	method, and therefore changes to such properties cannot be
2849	tracked. See individual object's property descriptions to get a
2850	fully qualified property name that can be used with this method (if
2851	any).
2852
2853	There is a special property mask @c "*" (i.e. a string consisting of a
2854	single asterisk symbol) that can be used to match all properties.
2855	Below are more examples of property masks:
2856
2857	<table>
2858	<tr>
2859	<td><tt>VirtualBox.*</tt></td>
2860	<td>Track all properties of the VirtualBox object</td>
2861	</tr>
2862	<tr>
2863	<td><tt>Machine.*.name</tt></td>
2864	<td>Track changes to the <link to="IMachine::name"/> property of
2865	all registered virtual machines</td>

3118	this descriptor file references other files, as OVF appliances distributed as a set of
3119	files most likely do, those files must be in the same directory as the descriptor file.</li>
3120
3121	<li>If the OVF is distributed as a single file, it must be in TAR format and have the
3122	<tt>.ova</tt> file extension. This TAR file must then contain at least the OVF descriptor
3123	files and optionally other files.

3130	<link to="IMachine" /> involves the following sequence of API calls:
3131
3132	<ol>
3133	<li>Call <link to="IVirtualBox::createAppliance" />. This will create an empty IAppliance object.
3134	</li>
3135
3136	<li>On the new object, call <link to="#read" /> with the full path of the OVF file you
3137	would like to import. So long as this file is syntactically valid, this will succeed
3138	and return an instance of IAppliance that contains the parsed data from the OVF file.
3139	</li>
3140
3141	<li>Next, call <link to="#interpret" />, which analyzes the OVF data and sets up the
3142	contents of the IAppliance attributes accordingly. These can be inspected by a
3143	VirtualBox front-end such as the GUI, and the suggestions can be displayed to the
3144	user. In particular, the <link to="#virtualSystemDescriptions" /> array contains
3145	instances of <link to="IVirtualSystemDescription" /> which represent the virtual
3146	systems in the OVF, which in turn describe the virtual hardware prescribed by the
3147	OVF (network and hardware adapters, virtual disk images, memory size and so on).
3148	The GUI can then give the user the option to confirm and/or change these suggestions.
3149	</li>
3150
3151	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
3152	virtual system to override the suggestions made by the interpret() routine.
3153	</li>
3154
3155	<li>Finally, call <link to="#importMachines" /> to create virtual machines in
3156	VirtualBox as instances of <link to="IMachine" /> that match the information in the
3157	virtual system descriptions.
3158	</li>
3159	</ol>
3160
3161	<b>Exporting</b> VirtualBox machines into an OVF appliance involves the following steps:
3162
3163	<ol>
3164	<li>As with importing, first call <link to="IVirtualBox::createAppliance" /> to create
3165	an empty IAppliance object.
3166	</li>
3167
3168	<li>For each machine you would like to export, call <link to="IMachine::export" />
3169	with the IAppliance object you just created. This creates an instance of
3170	<link to="IVirtualSystemDescription" /> inside the appliance.
3171	</li>
3172
3173	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
3174	virtual system to override the suggestions made by the export() routine.
3175	</li>
3176
3177	<li>Finally, call <link to="#write" /> with a path specification to have the OVF
3178	file written.</li>

3411	The list below identifies the value sets that are possible depending on the
3412	<link to="VirtualSystemDescriptionType" /> enum value in the array item in aTypes[]. In each case,
3413	the array item with the same index in aOvfValues[] will contain the original value as contained
3414	in the OVF file (just for informational purposes), and the corresponding item in aVBoxValues[]
3415	will contain a suggested value to be used for VirtualBox. Depending on the description type,
3416	the aExtraConfigValues[] array item may also be used.
3417
3418	<ul>
3419	<li>
3420	"OS": the guest operating system type. There must be exactly one such array item on import. The
3421	corresponding item in aVBoxValues[] contains the suggested guest operating system for VirtualBox.
3422	This will be one of the values listed in <link to="IVirtualBox::guestOSTypes" />. The corresponding
3423	item in aOvfValues[] will contain a numerical value that described the operating system in the OVF.
3424	</li>
3425	<li>
3426	"Name": the name to give to the new virtual machine. There can be at most one such array item;
3427	if none is present on import, then an automatic name will be created from the operating system
3428	type. The correponding item im aOvfValues[] will contain the suggested virtual machine name
3429	from the OVF file, and aVBoxValues[] will contain a suggestion for a unique VirtualBox
3430	<link to="IMachine" /> name that does not exist yet.
3431	</li>
3432	<li>
3433	"Description": an arbitrary description.
3434	</li>
3435	<li>
3436	"License": the EULA section from the OVF, if present. It is the responsibility of the calling
3437	code to display such a license for agreement; the Main API does not enforce any such policy.
3438	</li>
3439	<li>
3440	Miscellaneous: reserved for future use.
3441	</li>
3442	<li>
3443	"CPU": the number of CPUs. There can be at most one such item, which will presently be ignored.
3444	</li>
3445	<li>
3446	"Memory": the amount of guest RAM, in bytes. There can be at most one such array item; if none
3447	is present on import, then VirtualBox will set a meaningful default based on the operating system
3448	type.
3449	</li>
3450	<li>
3451	"HarddiskControllerIDE": an IDE hard disk controller. There can be at most one such item. This
3452	has no value in aOvfValues[] or aVBoxValues[].
3453	The matching item in the aRefs[] array will contain an integer that items of the "Harddisk"
3454	type can use to specify which hard disk controller a virtual disk should be connected to.
3455	</li>
3456	<li>
3457	"HarddiskControllerSATA": an SATA hard disk controller. There can be at most one such item. This
3458	has no value in aOvfValues[] or aVBoxValues[].
3459	The matching item in the aRefs[] array will be used as with IDE controllers (see above).
3460	</li>
3461	<li>
3462	"HarddiskControllerSCSI": a SCSI hard disk controller. There can be at most one such item.
3463	The items in aOvfValues[] and aVBoxValues[] will either be "LsiLogic" or "BusLogic".
3464	The matching item in the aRefs[] array will be used as with IDE controllers (see above).
3465	</li>
3466	<li>
3467	"HardDiskImage": a virtual hard disk, most probably as a reference to an image file. There can be an
3468	arbitrary number of these items, one for each virtual disk image that accompanies the OVF.
3469
3470	The array item in aOvfValues[] will contain the file specification from the OVF file (without
3471	a path since the image file should be in the same location as the OVF file itself), whereas the
3472	item in aVBoxValues[] will contain a qualified path specification to where VirtualBox uses the
3473	hard disk image. This means that on import the image will be copied and converted from the
3474	"ovf" location to the "vbox" location; on export, this will be handled the other way round.
3475	On import, the target image will also be registered with VirtualBox.
3476
3477	The matching item in the aExtraConfigValues[] array must contain a string of the following
3478	format: "controller=<index>;channel=<c>"
3479	In this string, <index> must be an integer specifying the hard disk controller to connect
3480	the image to. That number must be the index of an array item with one of the hard disk controller
3481	types (HarddiskControllerSCSI, HarddiskControllerSATA, HarddiskControllerIDE).
3482	In addition, <c> must specify the channel to use on that controller. For IDE controllers,
3483	this can range from 0-3 (which VirtualBox will interpret as primary master, primary slave, secondary master and
3484	secondary slave. For SATA and SCSI controllers, the channel can range from 0-29.
3485	</li>
3486	<li>
3487	"NetworkAdapter": a network adapter. The array item in aVBoxValues[] will specify the hardware
3488	for the network adapter, whereas the array item in aExtraConfigValues[] will have a string
3489	of the "type=<X>" format, where <X> must be either "NAT" or "Bridged".
3490	</li>
3491	<li>
3492	"USBController": a USB controller. There can be at most one such item. If and only if such an
3493	item ispresent, USB support will be enabled for the new virtual machine.
3494	</li>
3495	<li>
3496	"SoundCard": a sound card. There can be at most one such item. If and only if such an item is
3497	present, sound support will be enabled for the new virtual machine. Note that the virtual
3498	machine in VirtualBox will always be presented with the standard VirtualBox soundcard, which
3499	may be different from the virtual soundcard expected by the appliance.

4064	<desc>
4065	The IMachine interface represents a virtual machine, or guest, created
4066	in VirtualBox.
4067
4068	This interface is used in two contexts. First of all, a collection of
4069	objects implementing this interface is stored in the
4070	<link to="IVirtualBox::machines"/> attribute which lists all the virtual
4071	machines that are currently registered with this VirtualBox
4072	installation. Also, once a session has been opened for the given virtual
4073	machine (e.g. the virtual machine is running), the machine object
4074	associated with the open session can be queried from the session object;
4075	see <link to="ISession"/> for details.
4076
4077	The main role of this interface is to expose the settings of the virtual
4078	machine and provide methods to change various aspects of the virtual
4079	machine's configuration. For machine objects stored in the
4080	<link to="IVirtualBox::machines"/> collection, all attributes are
4081	read-only unless explicitly stated otherwise in individual attribute
4082	and method descriptions. In order to change a machine setting, a session
4083	for this machine must be opened using one of
4084	<link to="IVirtualBox::openSession"/>,
4085	<link to="IVirtualBox::openRemoteSession"/> or
4086	<link to="IVirtualBox::openExistingSession"/> methods. After the
4087	session has been successfully opened, a mutable machine object needs to
4088	be queried from the session object and then the desired settings changes
4089	can be applied to the returned object using IMachine attributes and
4090	methods. See the <link to="ISession"/> interface description for more
4091	information about sessions.
4092
4093	Note that IMachine does not provide methods to control virtual machine
4094	execution (such as start the machine, or power it down) -- these methods
4095	are grouped in a separate interface called <link to="IConsole" />.

4115	detailed error information describing the reason of
4116	inaccessibility, including XML error messages.
4117
4118	When the machine is inaccessible, only the following properties
4119	can be used on it:
4120	<ul>
4121	<li><link to="#parent"/></li>
4122	<li><link to="#id"/></li>
4123	<li><link to="#settingsFilePath"/></li>
4124	<li><link to="#accessible"/></li>
4125	<li><link to="#accessError"/></li>
4126	</ul>
4127
4128	An attempt to access any other property or method will return
4129	an error.
4130
4131	The only possible action you can perform on an inaccessible
4132	machine is to unregister it using the
4133	<link to="IVirtualBox::unregisterMachine"/> call (or, to check
4134	for the accessibility state once more by querying this
4135	property).
4136
4137	<note>
4138	In the current implementation, once this property returns
4139	@c true, the machine will never become inaccessible
4140	later, even if its settings file cannot be successfully
4141	read/written any more (at least, until the VirtualBox
4142	server is restarted). This limitation may be removed in
4143	future releases.

4162	Name of the virtual machine.
4163
4164	Besides being used for human-readable identification purposes
4165	everywhere in VirtualBox, the virtual machine name is also used
4166	as a name of the machine's settings file and as a name of the
4167	subdirectory this settings file resides in. Thus, every time you
4168	change the value of this property, the settings file will be
4169	renamed once you call <link to="#saveSettings"/> to confirm the
4170	change. The containing subdirectory will be also renamed, but
4171	only if it has exactly the same name as the settings file
4172	itself prior to changing this property (for backward compatibility
4173	with previous API releases). The above implies the following
4174	limitations:
4175	<ul>
4176	<li>The machine name cannot be empty.</li>
4177	<li>The machine name can contain only characters that are valid
4178	file name characters according to the rules of the file
4179	system used to store VirtualBox configuration.</li>
4180	<li>You cannot have two or more machines with the same name
4181	if they use the same subdirectory for storing the machine
4182	settings files.</li>
4183	<li>You cannot change the name of the machine if it is running,
4184	or if any file in the directory containing the settings file
4185	is being used by another running machine or by any other
4186	process in the host operating system at a time when
4187	<link to="#saveSettings"/> is called.
4188	</li>
4189	</ul>
4190	If any of the above limitations are hit, <link to="#saveSettings"/>
4191	will return an appropriate error message explaining the exact
4192	reason and the changes you made to this machine will not be
4193	saved.
4194	<note>
4195	For "legacy" machines created using the
4196	<link to="IVirtualBox::createLegacyMachine"/> call,
4197	the above naming limitations do not apply because the
4198	machine name does not affect the settings file name.
4199	The settings file name remains the same as it was specified
4200	during machine creation and never changes.

4645	@c 0 or @c 1, to specify the primary or secondary IDE controller,
4646	respectively. For each of these, @a device can then be either @c 0 or @c 1,
4647	to specify the master or the slave device, respectively. (In the
4648	default configuration of virtual machines, the secondary master is
4649	used for a CD/DVD drive.)
4650
4651	For an SATA controller, @a controllerPort must be a number ranging
4652	from @c 0 to @c 29. For a SCSI controller, @a controllerPort must
4653	be a number ranging from @c 0 to @c 15.
4654
4655	For both SCSI and SATA, the @a device parameter is unused and must
4656	be @c 0.
4657
4658	For fixed media such as hard disks, the given medium identifier cannot
4659	be a zero UUID. It may be a zero UUID for removable media such as DVDs
4660	and floppies.
4661
4662	After calling this returns successfully, a new instance of
4663	<link to="IMediumAttachment"/> will appear in the machine's list of medium
4664	attachments (<link to="IMachine::mediumAttachments"/>).
4665
4666	The specified device slot must not have a device attached to it,
4667	or this method will fail.
4668

4676	</note>
4677	<note>
4678	If the medium is being attached indirectly, a new differencing medium
4679	will implicitly be created for it and attached instead. If the
4680	changes made to the machine settings (including this indirect
4681	attachment) are later cancelled using <link to="#discardSettings"/>,
4682	this implicitly created differencing medium will implicitly
4683	be deleted.

5630	This interface is used by a client of the Main API that need to
5631	be notified of events. For example, a graphical user interface
5632	can use this to learn about machine state changes so they can
5633	update the list of virtual machines without having to rely
5634	on polling.
5635
5636	Whenever relevant events occur in VirtualBox, the callbacks in
5637	objects of this interface are called. In order for this to be
5638	useful, a client needs to create its own subclass that implements
5639	this interface in which the methods for the relevant callbacks
5640	are overridden. An instance of this subclass interface can then
5641	be passed to <link to="IConsole::registerCallback" />.

5685
5686	For pointers without alpha channel the XOR mask pixels are 32

5688	the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
5689

5692	displayed as a normal color pointer.
5693
5694	The AND mask is a 1-bpp bitmap with byte aligned scanlines. The
5695	size of the AND mask therefore is <tt>cbAnd = (width + 7) / 8 *
5696	height</tt>. The padding bits at the end of each scanline are
5697	undefined.
5698
5699	The XOR mask follows the AND mask on the next 4-byte aligned
5700	offset: <tt>uint8_t *pXor = pAnd + (cbAnd + 3) & ~3</tt>.
5701	Bytes in the gap between the AND and the XOR mask are undefined.
5702	The XOR mask scanlines have no gap between them and the size of
5703	the XOR mask is: <tt>cXor = width * 4 * height</tt>.

5884	<desc>
5885	Notification when an error happens during the virtual
5886	machine execution.
5887
5888	There are three kinds of runtime errors:
5889	<ul>
5890	<li><i>fatal</i></li>
5891	<li><i>non-fatal with retry</i></li>
5892	<li><i>non-fatal warnings</i></li>
5893	</ul>
5894
5895	<b>Fatal</b> errors are indicated by the @a fatal parameter set
5896	to @c true. In case of fatal errors, the virtual machine
5897	execution is always paused before calling this notification, and
5898	the notification handler is supposed either to immediately save
5899	the virtual machine state using <link to="IConsole::saveState"/>
5900	or power it off using <link to="IConsole::powerDown"/>.
5901	Resuming the execution can lead to unpredictable results.
5902
5903	<b>Non-fatal</b> errors and warnings are indicated by the
5904	@a fatal parameter set to @c false. If the virtual machine
5905	is in the Paused state by the time the error notification is
5906	received, it means that the user can <i>try to resume</i> the machine
5907	execution after attempting to solve the problem that caused the
5908	error. In this case, the notification handler is supposed
5909	to show an appropriate message to the user (depending on the
5910	value of the @a id parameter) that offers several actions such
5911	as <i>Retry</i>, <i>Save</i> or <i>Power Off</i>. If the user
5912	wants to retry, the notification handler should continue
5913	the machine execution using the <link to="IConsole::resume"/>
5914	call. If the machine execution is not Paused during this
5915	notification, then it means this notification is a <i>warning</i>
5916	(for example, about a fatal condition that can happen very soon);
5917	no immediate action is required from the user, the machine
5918	continues its normal execution.
5919
5920	Note that in either case the notification handler
5921	<b>must not</b> perform any action directly on a thread
5922	where this notification is called. Everything it is allowed to
5923	do is to post a message to another thread that will then talk
5924	to the user and take the corresponding action.
5925
5926	Currently, the following error identifiers are known:
5927	<ul>
5928	<li><tt>"HostMemoryLow"</tt></li>
5929	<li><tt>"HostAudioNotResponding"</tt></li>
5930	<li><tt>"VDIStorageFull"</tt></li>

5938	IConsole object, make sure you simply do nothing but

5994
5995	Note that many modern window managers on many platforms
5996	implement some sort of focus stealing prevention logic, so
5997	that it may be impossible to activate a window without the
5998	help of the currently active application (which is supposedly
5999	an initiator of this notification). In this case, this method
6000	must return a non-zero identifier that represents the
6001	top-level window of the VM console process. The caller, if it
6002	represents a currently active process, is responsible to use
6003	this identifier (in a platform-dependent manner) to perform
6004	actual window activation.
6005
6006	This method must set @a winId to zero if it has performed all
6007	actions necessary to complete the request and the console
6008	window is now active and in foreground, to indicate that no
6009	further action is required on the caller's side.

6696	<method name="deleteSnapshot">
6697	<desc>
6698	Starts discarding the specified snapshot asynchronously.
6699	See <link to="ISnapshot" /> for an introduction to snapshots.
6700
6701	The execution state and settings of the associated machine stored in
6702	the snapshot will be deleted. The contents of all differencing media of
6703	this snapshot will be merged with the contents of their dependent child
6704	media to keep the medium chain valid (in other words, all changes
6705	represented by media being discarded will be propagated to their child
6706	medium). After that, this snapshot's differencing medium will be
6707	deleted. The parent of this snapshot will become a new parent for all
6708	its child snapshots.
6709
6710	If the discarded snapshot is the current one, its parent
6711	snapshot will become a new current snapshot. The current machine
6712	state is not directly affected in this case, except that
6713	currently attached differencing media based on media
6714	of the discarded snapshot will be also merged as described
6715	above.
6716
6717	If the discarded snapshot is the first one (the root snapshot)
6718	and it has exactly one child snapshot, this child snapshot will
6719	become the first snapshot after discarding. If there are no
6720	children at all (i.e. the first snapshot is the only snapshot of
6721	the machine), both the current and the first snapshot of the
6722	machine will be set to @c null. In all other cases, the first
6723	snapshot cannot be discarded.
6724
6725	You cannot discard the snapshot if it
6726	stores <link to="MediumType_Normal">normal</link> (non-differencing)
6727	media that have differencing media based on them. Snapshots of
6728	such kind can be discarded only when every normal medium has either
6729	no children at all or exactly one child. In the former case, the normal
6730	medium simply becomes unused (i.e. not attached to any VM). In the
6731	latter case, it receives all the changes stored in the child medium,
6732	and then it replaces the child medium in the configuration of the
6733	corresponding snapshot or machine.
6734
6735	Also, you cannot discard the snapshot if it stores media
6736	(of any type) having differencing child media that belong
6737	to other machines. Such snapshots can be only discarded after
6738	you discard all snapshots of other machines containing "foreign"
6739	child media, or detach these "foreign" child media from machines
6740	they are attached to.
6741
6742	One particular example of the snapshot storing normal media
6743	is the first snapshot of a virtual machine that had normal media
6744	attached when taking the snapshot. Be careful when
6745	discarding such snapshots because this implicitly commits
6746	changes (made since the snapshot being discarded has been taken)
6747	to normal media (as described above), which may be not what
6748	you want.
6749
6750	The virtual machine is put to
6751	the <link to="MachineState_Discarding">Discarding</link> state until
6752	the discard operation is completed.
6753
6754	<note>
6755	The machine must not be running, otherwise the operation
6756	will fail.
6757	</note>
6758
6759	<note>

7612	Identifier of the default medium format used by VirtualBox.
7613
7614	The medium format set by this attribute is used by VirtualBox
7615	when the medium format was not specified explicitly. One example is
7616	<link to="IVirtualBox::createHardDisk"/> with the empty
7617	format argument. A more complex example is implicit creation of
7618	differencing media when taking a snapshot of a virtual machine:
7619	this operation will try to use a format of the parent medium first
7620	and if this format does not support differencing media the default
7621	format specified by this argument will be used.
7622
7623	The list of supported medium formats may be obtained by the
7624	<link to="#mediaFormats"/> call. Note that the default medium
7625	format must have a capability to create differencing media;
7626	otherwise operations that create media implicitly may fail

7674
7675	As opposed to <link to="ISystemProperties::remoteDisplayAuthLibrary" />,
7676	there is no per-VM setting for this, as the webservice is a global
7677	resource (if it is running). Only for this setting (for the webservice),
7678	setting this value to a literal <tt>"null"</tt> string disables authentication,
7679	meaning that <link to="IWebsessionManager::logon" /> will always succeed,
7680	no matter what user name and password are supplied.
7681
7682	The initial value of this property is <tt>"VRDPAuth"</tt>,
7683	meaning that the webservice will use the same authentication
7684	library that is used by default for VBoxVRDP (again, see
7685	<link to="ISystemProperties::remoteDisplayAuthLibrary" />).
7686	The format and calling convention of authentication libraries

7948	<desc>
7949	The IProgress interface is used to track and control
7950	asynchronous tasks within VirtualBox.
7951
7952	An instance of this is returned every time VirtualBox starts
7953	an asynchronous task (in other words, a separate thread) which
7954	continues to run after a method call returns. For example,
7955	<link to="IConsole::saveState" />, which saves the state of
7956	a running virtual machine, can take a long time to complete.
7957	To be able to display a progress bar, a user interface such as
7958	the VirtualBox graphical user interface can use the IProgress
7959	object returned by that method.
7960
7961	Note that IProgress is a "read-only" interface in the sense
7962	that only the VirtualBox internals behind the Main API can
7963	create and manipulate progress objects, whereas client code
7964	can only use the IProgress object to monitor a task's
7965	progress and, if <link to="#cancelable" /> is @c true,
7966	cancel the task by calling <link to="#cancel" />.
7967
7968	A task represented by IProgress consists of either one or
7969	several sub-operations that run sequentially, one by one (see
7970	<link to="#operation" /> and <link to="#operationCount" />).
7971	Every operation is identified by a number (starting from 0)
7972	and has a separate description.
7973
7974	You can find the individual percentage of completion of the current
7975	operation in <link to="#operationPercent" /> and the
7976	percentage of completion of the task as a whole
7977	in <link to="#percent" />.
7978
7979	Similarly, you can wait for the completion of a particular
7980	operation via <link to="#waitForOperationCompletion" /> or
7981	for the completion of the whole task via
7982	<link to="#waitForCompletion" />.

8015

8144	wsmap="managed"
8145	>
8146	<desc>
8147	The ISnapshot interface represents a snapshot of the virtual
8148	machine.
8149
8150	Together with the differencing media that are created
8151	when a snapshot is taken, a machine can be brought back to
8152	the exact state it was in when the snapshot was taken.
8153
8154	The ISnapshot interface has no methods, only attributes; snapshots
8155	are controlled through methods of the <link to="IConsole" /> interface
8156	which also manage the media associated with the snapshot.
8157	The following operations exist:
8158
8159	<ul>
8160	<li><link to="IConsole::takeSnapshot"/>: creates a new snapshot
8161	by creating new, empty differencing images for the machine's
8162	media and saving the VM settings and (if the VM is running)
8163	the current VM state in the snapshot.
8164
8165	The differencing images will then receive all data written to
8166	the machine's media, while their parent (base) images
8167	remain unmodified after the snapshot has been taken (see
8168	<link to="IMedium" /> for details about differencing images).
8169	This simplifies restoring a machine to the state of a snapshot:
8170	only the differencing images need to be deleted.
8171
8172	The current machine state is not changed by taking a snapshot.
8173	If the machine is running, it will resume execution after the
8174	snapshot has been taken.
8175	</li>
8176
8177	<li><link to="IConsole::restoreSnapshot"/>: this goes back to
8178	a previous snapshot. This resets the machine's state to that of
8179	the previous snapshot by deleting the differencing image of each
8180	of the machine's media and setting the machine's settings
8181	and state to the state that was saved in the snapshot (if any).
8182
8183	This destroys the machine's current state.
8184	</li>
8185
8186	<li><link to="IConsole::deleteSnapshot"/>: deletes a snapshot
8187	without affecting the current machine state.
8188
8189	This does not change the machine, but instead frees the resources
8190	allocated when the snapshot was taken: the settings and machine state
8191	is deleted (if any), and the snapshot's differencing image for each
8192	of the machine's media gets merged with its parent image.
8193
8194	Neither the current machine state nor other snapshots are affected
8195	by this operation, except that parent media will be modified
8196	to contain the disk data associated with the snapshot being deleted.
8197	</li>
8198	</ul>
8199
8200	Each snapshot contains the settings of the virtual machine (hardware
8201	configuration etc.). In addition, if the machine was running when the
8202	snapshot was taken (<link to="IMachine::state"/> is <link to="MachineState_Running"/>),
8203	the current VM state is saved in the snapshot (similarly to what happens
8204	when a VM's state is saved). The snapshot is then said to
8205	be <i>online</i> because when restoring it, the VM will be running.
8206
8207	If the machine is saved (<link to="MachineState_Saved"/>), the snapshot
8208	receives a copy of the execution state file (<link to="IMachine::stateFilePath"/>).
8209
8210	Otherwise, if the machine was not running (<link to="MachineState_PoweredOff"/>
8211	or <link to="MachineState_Aborted"/>), the snapshot is <i>offline</i>;
8212	it then contains a so-called "zero execution state", representing a
8213	machine that is powered off.
8214
8215	<h3>Snapshot branches and the "current" snapshot</h3>
8216
8217	Snapshots can be chained, whereby every next snapshot is based on the
8218	previous one. This chaining is related to medium branching
8219	(see the <link to="IMedium"/> description) in that every time
8220	a new snapshot is created, a new differencing medium is implicitly
8221	created for all normal media attached to the machine.
8222
8223	Each virtual machine has a "current snapshot", identified by
8224	<link to="IMachine::currentSnapshot"/>. Presently, this is always set
8225	to the last snapshot in the chain. In a future version of VirtualBox,
8226	it will be possible to reset a machine's current state to that of an
8227	earlier snapshot without discarding the current state so that it will be
8228	possible to create alternative snapshot paths in a snapshot tree.
8229
8230	In the current implementation, multiple snapshot branches within one
8231	virtual machine are not allowed. Every machine has a single branch,
8232	and <link to="IConsole::takeSnapshot"/> operation adds a new
8233	snapshot to the top of that branch.

8428	The IMediumAttachment interface represents the attachment
8429	of a storage medium to a virtual machine. Each machine contains
8430	an array of its medium attachments in <link to="IMachine::mediumAttachments"/>.
8431
8432	Each medium attachment specifies a storage controller as well as a port
8433	and device number. Fixed media (hard disks) will always also specify
8434	an instance of IMedium in <link to="#medium" />, referring to the hard disk
8435	medium. For removeable media, the IMedia instance is optional; it can be

8471	<desc>
8472	The IMedium interface represents virtual storage for a machine's
8473	hard disks, CD/DVD or floppy drives. It will typically represent
8474	a disk image on the host, for example a VDI or VMDK file representing
8475	a virtual hard disk, or an ISO or RAW file representing virtual
8476	removable media, but can also point to a network location (e.g.
8477	for iSCSI targets).
8478
8479	Instances of IMedium are connected to virtual machines by way of
8480	medium attachments (see <link to="IMediumAttachment" />), which link
8481	the storage medium to a particular device slot of a storage controller
8482	of the virtual machine.
8483	In the VirtualBox API, virtual storage is therefore always represented
8484	by the following chain of object links:
8485
8486	<ul>
8487	<li><link to="IMachine::storageControllers"/> contains an array of
8488	storage controllers (IDE, SATA, SCSI or a floppy controller;
8489	these are instances of <link to="IStorageController"/>).</li>
8490	<li><link to="IMachine::mediumAttachments"/> contains an array of
8491	medium attachments (instances of <link to="IMediumAttachment"/>),
8492	each containing the name of a storage controller from the above
8493	array, a port/device specification, and an instance of
8494	IMedium representing the medium storage (image file). For removable
8495	media, the storage medium is optional; a medium attachment with no
8496	medium represents a CD/DVD or floppy drive with no medium inserted.
8497	By contrast, hard disk attachments will always have an IMedium
8498	object attached.</li>
8499	<li>Each IMedium in turn points to a storage unit (such as a file on the host
8500	computer or a network resource) that holds actual data. The location of
8501	the storage unit is represented by the <link to="#location"/> attribute.
8502	The value of this attribute is medium type dependent.</li>
8503	</ul>
8504
8505	Existing media are opened using the following methods, depending on the
8506	media type:
8507	<ul>
8508	<li><link to="IVirtualBox::openHardDisk"/></li>
8509	<li><link to="IVirtualBox::openDVDImage"/></li>
8510	<li><link to="IVirtualBox::openFloppyImage"/></li>
8511	</ul>
8512
8513	New hard disk media can be created with the VirtualBox API using the
8514	<link to="IVirtualBox::createHardDisk"/> method.
8515
8516	CD/DVD and floppy images (ISO and RAW files) are usually created outside
8517	VirtualBox, e.g. by storing a copy of the real medium of the corresponding
8518	type in a regular file.
8519
8520	Only for CD/DVDs and floppies, an IMedium instance can also represent a host
8521	drive; in that case the <link to="#id" /> attribute contains the UUID of
8522	one of the drives in <link to="IHost::DVDDrives" /> or <link to="IHost::floppyDrives" />.
8523
8524	<h3>Known media</h3>
8525
8526	When an existing medium is opened for the first time, it is automatically
8527	remembered by the given VirtualBox installation or, in other words, becomes
8528	a <i>known medium</i>. Known media are stored in the media
8529	registry transparently maintained by VirtualBox and stored in settings
8530	files so that this registry is preserved when VirtualBox is not running.
8531
8532	Newly created virtual media are remembered only when the associated
8533	storage unit is actually created.
8534
8535	All known media can be enumerated using
8536	<link to="IVirtualBox::hardDisks"/>,
8537	<link to="IVirtualBox::DVDImages"/> and
8538	<link to="IVirtualBox::floppyImages"/> attributes. Individual media can be
8539	quickly found by UUID using <link to="IVirtualBox::getHardDisk"/>
8540	and similar methods or by location using
8541	<link to="IVirtualBox::findHardDisk"/> and similar methods.
8542
8543	Only known media can be attached to virtual machines.
8544
8545	Removing known media from the media registry is performed when the given
8546	medium is closed using the <link to="#close"/> method or when its
8547	associated storage unit is deleted.
8548
8549	<h3>Accessibility checks</h3>
8550
8551	The given medium (with the created storage unit) is considered to be
8552	<i>accessible</i> when its storage unit can be read. In that case, the
8553	<link to="#state"/> attribute has a value of "Created".
8554	When the storage unit cannot be read (for example, because it is located on
8555	a disconnected network resource, or was accidentally deleted outside VirtualBox),
8556	the medium is considered to be <i>inaccessible</i>, which is indicated by the
8557	"Inaccessible" state. The exact reason why the medium is inaccessible can be
8558	obtained by reading the <link to="#lastAccessError"/> attribute.
8559
8560	A new accessibility check is performed each time the <link to="#state"/>
8561	attribute is read. This check may take long time (several seconds or even
8562	minutes, depending on the storage unit location and format), and will
8563	block the calling thread until finished. For this reason, it is recommended
8564	to never read this attribute on the main UI thread to avoid making the UI
8565	unresponsive.
8566
8567	Note that when VirtualBox starts up (e.g. the VirtualBox object gets
8568	created for the first time), all known media are in the
8569	<link to="MediumState_Inaccessible"/> state but the value of the <link
8570	to="#lastAccessError"/> attribute is an empty string because no actual
8571	accessibility check is made on startup. This is done to make the
8572	VirtualBox object ready for serving requests as
8573	fast as possible and let the end-user application decide if it needs to
8574	check media accessibility right away or not.
8575
8576	<h3>Medium types</h3>
8577
8578	There are three types of medium behavior (see <link to="MediumType" />):
8579	"normal", "immutable" and "writethrough", represented by the
8580	<link to="#type"/> attribute. The type of the medium defines how the
8581	medium is attached to a virtual machine and what happens when a
8582	<link to="ISnapshot">snapshot</link> of the virtual machine with the
8583	attached medium is taken. At the moment DVD and floppy media are always
8584	of type "writethrough".
8585
8586	All media can be also divided in two groups: <i>base</i> media and
8587	<i>differencing</i> media. A base medium contains all sectors of the
8588	medium data in its own storage and therefore can be used independently.
8589	In contrast, a differencing mediun is a "delta" to some other medium and
8590	contains only those sectors which differ from that other medium, which is
8591	then called a <i>parent</i>. The differencing medium is said to be
8592	<i>linked to</i> that parent. The parent may be itself a differencing
8593	medium, thus forming a chain of linked media. The last element in that
8594	chain must always be a base medium. Note that several differencing
8595	media may be linked to the same parent medium.
8596
8597	Differencing media can be distinguished from base media by querying the
8598	<link to="#parent"/> attribute: base media do not have parents they would
8599	depend on, so the value of this attribute is always @c null for them.
8600	Using this attribute, it is possible to walk up the medium tree (from the
8601	child medium to its parent). It is also possible to walk down the tree
8602	using the <link to="#children"/> attribute.
8603
8604	Note that the type of all differencing media is
8605	<link to="MediumType_Normal" />; all other values are meaningless for
8606	them. Base media may be of any type.
8607
8608	<h3>Creating hard disks</h3>
8609
8610	New base hard disks are created using
8611	<link to="IVirtualBox::createHardDisk"/>. Existing hard disks are
8612	opened using <link to="IVirtualBox::openHardDisk"/>. Differencing hard
8613	disks are usually implicitly created by VirtualBox when needed but may
8614	also be created explicitly using <link to="#createDiffStorage"/>.
8615
8616	After the hard disk is successfully created (including the storage unit)
8617	or opened, it becomes a known hard disk (remembered in the internal media
8618	registry). Known hard disks can be attached to a virtual machine, accessed
8619	through <link to="IVirtualBox::getHardDisk"/> and
8620	<link to="IVirtualBox::findHardDisk"/> methods or enumerated using the
8621	<link to="IVirtualBox::hardDisks"/> array (only for base hard disks).
8622
8623	The following methods, besides <link to="IMedium::close"/>,
8624	automatically remove the hard disk from the media registry:
8625	<ul>
8626	<li><link to="#deleteStorage"/></li>
8627	<li><link to="#mergeTo"/></li>
8628	</ul>
8629
8630	If the storage unit of the hard disk is a regular file in the host's
8631	file system then the rules stated in the description of the
8632	<link to="IMedium::location"/> attribute apply when setting its value. In
8633	addition, a plain file name without any path may be given, in which case
8634	the <link to="ISystemProperties::defaultHardDiskFolder"> default hard disk
8635	folder</link> will be prepended to it.
8636
8637	<h4>Automatic composition of the file name part</h4>
8638
8639	Another extension to the <link to="IMedium::location"/> attribute is that
8640	there is a possibility to cause VirtualBox to compose a unique value for
8641	the file name part of the location using the UUID of the hard disk. This
8642	applies only to hard disks in <link to="MediumState_NotCreated"/> state,
8643	e.g. before the storage unit is created, and works as follows. You set the
8644	value of the <link to="IMedium::location"/> attribute to a location
8645	specification which only contains the path specification but not the file
8646	name part and ends with either a forward slash or a backslash character.
8647	In response, VirtualBox will generate a new UUID for the hard disk and
8648	compose the file name using the following pattern:
8649	<pre>
8650	<path>/{<uuid>}.<ext>
8651	</pre>
8652	where <tt><path></tt> is the supplied path specification,
8653	<tt><uuid></tt> is the newly generated UUID and <tt><ext></tt>
8654	is the default extension for the storage format of this hard disk. After
8655	that, you may call any of the methods that create a new hard disk storage
8656	unit and they will use the generated UUID and file name.
8657
8658	<h3>Attaching Hard Disks</h3>
8659
8660	Hard disks are attached to virtual machines using the
8661	<link to="IMachine::attachDevice"/> method and detached using the
8662	<link to="IMachine::detachDevice"/> method. Depending on their
8663	<link to="#type"/>, hard disks are attached either
8664	<i>directly</i> or <i>indirectly</i>.
8665
8666	When a hard disk is being attached directly, it is associated with the
8667	virtual machine and used for hard disk operations when the machine is
8668	running. When a hard disk is being attached indirectly, a new differencing
8669	hard disk linked to it is implicitly created and this differencing hard
8670	disk is associated with the machine and used for hard disk operations.
8671	This also means that if <link to="IMachine::attachDevice"/> performs
8672	a direct attachment then the same hard disk will be returned in response
8673	to the subsequent <link to="IMachine::getMedium"/> call; however if
8674	an indirect attachment is performed then
8675	<link to="IMachine::getMedium"/> will return the implicitly created
8676	differencing hard disk, not the original one passed to <link
8677	to="IMachine::attachDevice"/>. In detail:
8678
8679	<ul>
8680	<li><b>Normal base</b> hard disks that do not have children (i.e.
8681	differencing hard disks linked to them) and that are not already
8682	attached to virtual machines in snapshots are attached <b>directly</b>.
8683	Otherwise, they are attached <b>indirectly</b> because having
8684	dependent children or being part of the snapshot makes it impossible
8685	to modify hard disk contents without breaking the integrity of the
8686	dependent party. The <link to="#readOnly"/> attribute allows to
8687	quickly determine the kind of the attachment for the given hard
8688	disk. Note that if a normal base hard disk is to be indirectly
8689	attached to a virtual machine with snapshots then a special
8690	procedure called <i>smart attachment</i> is performed (see below).</li>
8691	<li><b>Normal differencing</b> hard disks are like normal base hard disks:
8692	they are attached <b>directly</b> if they do not have children and are
8693	not attached to virtual machines in snapshots, and <b>indirectly</b>
8694	otherwise. Note that the smart attachment procedure is never performed
8695	for differencing hard disks.</li>
8696	<li><b>Immutable</b> hard disks are always attached <b>indirectly</b> because
8697	they are designed to be non-writable. If an immutable hard disk is
8698	attached to a virtual machine with snapshots then a special
8699	procedure called smart attachment is performed (see below).</li>
8700	<li><b>Writethrough</b> hard disks are always attached <b>directly</b>,
8701	also as designed. This also means that writethrough hard disks cannot
8702	have other hard disks linked to them at all.</li>
8703	</ul>
8704
8705	Note that the same hard disk, regardless of its type, may be attached to
8706	more than one virtual machine at a time. In this case, the machine that is
8707	started first gains exclusive access to the hard disk and attempts to
8708	start other machines having this hard disk attached will fail until the
8709	first machine is powered down.
8710
8711	Detaching hard disks is performed in a <i>deferred</i> fashion. This means
8712	that the given hard disk remains associated with the given machine after a
8713	successful <link to="IMachine::detachDevice"/> call until
8714	<link to="IMachine::saveSettings"/> is called to save all changes to
8715	machine settings to disk. This deferring is necessary to guarantee that
8716	the hard disk configuration may be restored at any time by a call to
8717	<link to="IMachine::discardSettings"/> before the settings
8718	are saved (committed).
8719
8720	Note that if <link to="IMachine::discardSettings"/> is called after
8721	indirectly attaching some hard disks to the machine but before a call to
8722	<link to="IMachine::saveSettings"/> is made, it will implicitly delete
8723	all differencing hard disks implicitly created by
8724	<link to="IMachine::attachDevice"/> for these indirect attachments.
8725	Such implicitly created hard disks will also be immediately deleted when
8726	detached explicitly using the <link to="IMachine::detachDevice"/>
8727	call if it is made before <link to="IMachine::saveSettings"/>. This
8728	implicit deletion is safe because newly created differencing hard
8729	disks do not contain any user data.
8730
8731	However, keep in mind that detaching differencing hard disks that were
8732	implicitly created by <link to="IMachine::attachDevice"/>
8733	before the last <link to="IMachine::saveSettings"/> call will
8734	<b>not</b> implicitly delete them as they may already contain some data
8735	(for example, as a result of virtual machine execution). If these hard
8736	disks are no more necessary, the caller can always delete them explicitly
8737	using <link to="#deleteStorage"/> after they are actually de-associated
8738	from this machine by the <link to="IMachine::saveSettings"/> call.
8739
8740	<h3>Smart Attachment</h3>
8741
8742	When normal base or immutable hard disks are indirectly attached to a
8743	virtual machine then some additional steps are performed to make sure the
8744	virtual machine will have the most recent "view" of the hard disk being
8745	attached. These steps include walking through the machine's snapshots
8746	starting from the current one and going through ancestors up to the first
8747	snapshot. Hard disks attached to the virtual machine in all
8748	of the encountered snapshots are checked whether they are descendants of
8749	the given normal base or immutable hard disk. The first found child (which
8750	is the differencing hard disk) will be used instead of the normal base or
8751	immutable hard disk as a parent for creating a new differencing hard disk
8752	that will be actually attached to the machine. And only if no descendants
8753	are found or if the virtual machine does not have any snapshots then the
8754	normal base or immutable hard disk will be used itself as a parent for
8755	this differencing hard disk.
8756
8757	It is easier to explain what smart attachment does using the
8758	following example:
8759	<pre>
8760	BEFORE attaching B.vdi: AFTER attaching B.vdi:
8761
8762	Snapshot 1 (B.vdi) Snapshot 1 (B.vdi)
8763	Snapshot 2 (D1->B.vdi) Snapshot 2 (D1->B.vdi)
8764	Snapshot 3 (D2->D1.vdi) Snapshot 3 (D2->D1.vdi)
8765	Snapshot 4 (none) Snapshot 4 (none)
8766	CurState (none) CurState (D3->D2.vdi)
8767
8768	NOT
8769	...
8770	CurState (D3->B.vdi)
8771	</pre>
8772	The first column is the virtual machine configuration before the base hard
8773	disk <tt>B.vdi</tt> is attached, the second column shows the machine after
8774	this hard disk is attached. Constructs like <tt>D1->B.vdi</tt> and similar
8775	mean that the hard disk that is actually attached to the machine is a
8776	differencing hard disk, <tt>D1.vdi</tt>, which is linked to (based on)
8777	another hard disk, <tt>B.vdi</tt>.
8778
8779	As we can see from the example, the hard disk <tt>B.vdi</tt> was detached
8780	from the machine before taking Snapshot 4. Later, after Snapshot 4 was
8781	taken, the user decides to attach <tt>B.vdi</tt> again. <tt>B.vdi</tt> has
8782	dependent child hard disks (<tt>D1.vdi</tt>, <tt>D2.vdi</tt>), therefore
8783	it cannot be attached directly and needs an indirect attachment (i.e.
8784	implicit creation of a new differencing hard disk). Due to the smart
8785	attachment procedure, the new differencing hard disk
8786	(<tt>D3.vdi</tt>) will be based on <tt>D2.vdi</tt>, not on
8787	<tt>B.vdi</tt> itself, since <tt>D2.vdi</tt> is the most recent view of
8788	<tt>B.vdi</tt> existing for this snapshot branch of the given virtual
8789	machine.
8790
8791	Note that if there is more than one descendant hard disk of the given base
8792	hard disk found in a snapshot, and there is an exact device, channel and
8793	bus match, then this exact match will be used. Otherwise, the youngest
8794	descendant will be picked up.
8795
8796	There is one more important aspect of the smart attachment procedure which
8797	is not related to snapshots at all. Before walking through the snapshots
8798	as described above, the backup copy of the current list of hard disk
8799	attachment is searched for descendants. This backup copy is created when
8800	the hard disk configuration is changed for the first time after the last
8801	<link to="IMachine::saveSettings"/> call and used by
8802	<link to="IMachine::discardSettings"/> to undo the recent hard disk
8803	changes. When such a descendant is found in this backup copy, it will be
8804	simply re-attached back, without creating a new differencing hard disk for
8805	it. This optimization is necessary to make it possible to re-attach the
8806	base or immutable hard disk to a different bus, channel or device slot
8807	without losing the contents of the differencing hard disk actually
8808	attached to the machine in place of it.

8848	Reading this attribute may take a long time because an accessibility
8849	check of the storage unit is performed each time the attribute is read.
8850	This check may cause a significant delay if the storage unit of the
8851	given medium is, for example, a file located on a network share which is
8852	not currently accessible due to connectivity problems -- the call will
8853	not return until a timeout interval defined by the host OS for this

8871	Location of the storage unit holding medium data.
8872
8873	The format of the location string is medium type specific. For medium
8874	types using regular files in a host's file system, the location
8875	string is the full file name.
8876
8877	Some medium types may support changing the storage unit location by

8882	When setting a value of the location attribute which is a regular file
8883	in the host's file system, the given file name may be either relative to
8884	the <link to="IVirtualBox::homeFolder">VirtualBox home folder</link> or
8885	absolute. Note that if the given location specification does not contain

9548	<method name="mergeTo">
9549	<desc>
9550	Starts merging the contents of this medium and all intermediate
9551	differencing media in the chain to the given target medium.
9552
9553	The target medium must be either a descendant of this medium or
9554	its ancestor (otherwise this method will immediately return a failure).
9555	It follows that there are two logical directions of the merge operation:
9556	from ancestor to descendant (<i>forward merge</i>) and from descendant to
9557	ancestor (<i>backward merge</i>). Let us consider the following medium
9558	chain:
9559
9560	<pre>Base <- Diff_1 <- Diff_2</pre>
9561
9562	Here, calling this method on the <tt>Base</tt> medium object with
9563	<tt>Diff_2</tt> as an argument will be a forward merge; calling it on
9564	<tt>Diff_2</tt> with <tt>Base</tt> as an argument will be a backward
9565	merge. Note that in both cases the contents of the resulting medium
9566	will be the same, the only difference is the medium object that takes
9567	the result of the merge operation. In case of the forward merge in the
9568	above example, the result will be written to <tt>Diff_2</tt>; in case of
9569	the backward merge, the result will be written to <tt>Base</tt>. In
9570	other words, the result of the operation is always stored in the target
9571	medium.
9572
9573	Upon successful operation completion, the storage units of all media in
9574	the chain between this (source) medium and the target medium, including
9575	the source medium itself, will be automatically deleted and the
9576	relevant medium objects (including this medium) will become
9577	uninitialized. This means that any attempt to call any of
9578	their methods or attributes will fail with the
9579	<tt>"Object not ready" (E_ACCESSDENIED)</tt> error. Applied to the above
9580	example, the forward merge of <tt>Base</tt> to <tt>Diff_2</tt> will
9581	delete and uninitialize both <tt>Base</tt> and <tt>Diff_1</tt> media.
9582	Note that <tt>Diff_2</tt> in this case will become a base medium
9583	itself since it will no longer be based on any other medium.
9584
9585	Considering the above, all of the following conditions must be met in
9586	order for the merge operation to succeed:
9587	<ul>
9588	<li>
9589	Neither this (source) medium nor any intermediate
9590	differencing medium in the chain between it and the target
9591	medium is attached to any virtual machine.
9592	</li>
9593	<li>
9594	Neither the source medium nor the target medium is an
9595	<link to="MediumType_Immutable"/> medium.
9596	</li>
9597	<li>
9598	The part of the medium tree from the source medium to the
9599	target medium is a linear chain, i.e. all medium in this
9600	chain have exactly one child which is the next medium in this
9601	chain. The only exception from this rule is the target medium in
9602	the forward merge operation; it is allowed to have any number of
9603	child media because the merge operation will not change its
9604	logical contents (as it is seen by the guest OS or by children).
9605	</li>
9606	<li>
9607	None of the involved media are in
9608	<link to="MediumState_LockedRead"/> or
9609	<link to="MediumState_LockedWrite"/> state.
9610	</li>
9611	</ul>
9612
9613	<note>
9614	This (source) medium and all intermediates will be placed to <link
9615	to="MediumState_Deleting"/> state and the target medium will be
9616	placed to <link to="MediumState_LockedWrite"/> state and for the
9617	duration of this operation.

9632	Starts creating a clone of this medium in the format and at the

9634
9635	The target medium must be either in <link to="MediumState_NotCreated"/>
9636	state (i.e. must not have an existing storage unit) or in
9637	<link to="MediumState_Created"/> state (i.e. created and not locked, and

9643
9644	The @a parent argument defines which medium will be the parent
9645	of the clone. Passing a @c null reference indicates that the clone will

9861	The IMediumFormat interface represents a medium format.

9867	Each medium format is identified by a string represented by the

10340	There are two modes of working with the video buffer of the virtual
10341	machine. The <i>indirect</i> mode implies that the IFramebuffer
10342	implementation allocates a memory buffer for the requested display mode
10343	and provides it to the virtual machine. In <i>direct</i> mode, the
10344	IFramebuffer implementation uses the memory buffer allocated and owned
10345	by the virtual machine. This buffer represents the video memory of the
10346	emulated video adapter (so called <i>guest VRAM</i>). The direct mode is
10347	usually faster because the implementation gets a raw pointer to the
10348	guest VRAM buffer which it can directly use for visualizing the contents
10349	of the virtual display, as opposed to the indirect mode where the
10350	contents of guest VRAM are copied to the memory buffer provided by
10351	the implementation every time a display update occurs.
10352
10353	It is important to note that the direct mode is really fast only when
10354	the implementation uses the given guest VRAM buffer directly, for
10355	example, by blitting it to the window representing the virtual machine's
10356	display, which saves at least one copy operation comparing to the
10357	indirect mode. However, using the guest VRAM buffer directly is not
10358	always possible: the format and the color depth of this buffer may be
10359	not supported by the target window, or it may be unknown (opaque) as in
10360	case of text or non-linear multi-plane VGA video modes. In this case,
10361	the indirect mode (that is always available) should be used as a
10362	fallback: when the guest VRAM contents are copied to the
10363	implementation-provided memory buffer, color and format conversion is
10364	done automatically by the underlying code.
10365
10366	The @a pixelFormat parameter defines whether the direct mode is
10367	available or not. If @a pixelFormat is <link
10368	to="FramebufferPixelFormat_Opaque"/> then direct access to the guest
10369	VRAM buffer is not available -- the @a VRAM, @a bitsPerPixel and
10370	@a bytesPerLine parameters must be ignored and the implementation must use
10371	the indirect mode (where it provides its own buffer in one of the
10372	supported formats). In all other cases, @a pixelFormat together with
10373	@a bitsPerPixel and @a bytesPerLine define the format of the video memory
10374	buffer pointed to by the @a VRAM parameter and the implementation is
10375	free to choose which mode to use. To indicate that this frame buffer uses
10376	the direct mode, the implementation of the <link to="#usesGuestVRAM"/>
10377	attribute must return @c true and <link to="#address"/> must
10378	return exactly the same address that is passed in the @a VRAM parameter
10379	of this method; otherwise it is assumed that the indirect strategy is
10380	chosen.
10381
10382	The @a width and @a height parameters represent the size of the
10383	requested display mode in both modes. In case of indirect mode, the
10384	provided memory buffer should be big enough to store data of the given
10385	display mode. In case of direct mode, it is guaranteed that the given
10386	@a VRAM buffer contains enough space to represent the display mode of the
10387	given size. Note that this frame buffer's <link to="#width"/> and <link
10388	to="#height"/> attributes must return exactly the same values as
10389	passed to this method after the resize is completed (see below).
10390
10391	The @a finished output parameter determines if the implementation has
10392	finished resizing the frame buffer or not. If, for some reason, the
10393	resize cannot be finished immediately during this call, @a finished
10394	must be set to @c false, and the implementation must call
10395	<link to="IDisplay::resizeCompleted"/> after it has returned from
10396	this method as soon as possible. If @a finished is @c false, the
10397	machine will not call any frame buffer methods until
10398	<link to="IDisplay::resizeCompleted"/> is called.
10399
10400	Note that if the direct mode is chosen, the <link to="#bitsPerPixel"/>,
10401	<link to="#bytesPerLine"/> and <link to="#pixelFormat"/> attributes of
10402	this frame buffer must return exactly the same values as specified in the
10403	parameters of this method, after the resize is completed. If the
10404	indirect mode is chosen, these attributes must return values describing
10405	the format of the implementation's own memory buffer <link
10406	to="#address"/> points to. Note also that the <link to="#bitsPerPixel"/>
10407	value must always correlate with <link to="#pixelFormat"/>. Note that
10408	the <link to="#pixelFormat"/> attribute must never return <link
10409	to="FramebufferPixelFormat_Opaque"/> regardless of the selected mode.
10410
10411	<note>
10412	This method is called by the IDisplay object under the
10413	<link to="#lock"/> provided by this IFramebuffer
10414	implementation. If this method returns @c false in @a finished, then
10415	this lock is not released until

11533	<desc>
11534	The IUSBDeviceFilter interface represents an USB device filter used
11535	to perform actions on a group of USB devices.
11536
11537	This type of filters is used by running virtual machines to
11538	automatically capture selected USB devices once they are physically
11539	attached to the host computer.
11540
11541	A USB device is matched to the given device filter if and only if all
11542	attributes of the device match the corresponding attributes of the
11543	filter (that is, attributes are joined together using the logical AND
11544	operation). On the other hand, all together, filters in the list of
11545	filters carry the semantics of the logical OR operation. So if it is
11546	desirable to create a match like "this vendor id OR this product id",
11547	one needs to create two filters and specify "any match" (see below)
11548	for unused attributes.
11549
11550	All filter attributes used for matching are strings. Each string
11551	is an expression representing a set of values of the corresponding
11552	device attribute, that will match the given filter. Currently, the
11553	following filtering expressions are supported:
11554
11555	<ul>
11556	<li><i>Interval filters</i>. Used to specify valid intervals for
11557	integer device attributes (Vendor ID, Product ID and Revision).
11558	The format of the string is:
11559
11560	<tt>int:((m)\|([m]-[n]))(,(m)\|([m]-[n]))*</tt>
11561
11562	where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
11563	(starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
11564	or decimal (otherwise) form, so that <tt>m < n</tt>. If <tt>m</tt>
11565	is omitted before a dash (<tt>-</tt>), the minimum possible integer
11566	is assumed; if <tt>n</tt> is omitted after a dash, the maximum
11567	possible integer is assumed.
11568	</li>
11569	<li><i>Boolean filters</i>. Used to specify acceptable values for
11570	boolean device attributes. The format of the string is:
11571
11572	<tt>true\|false\|yes\|no\|0\|1</tt>
11573
11574	</li>
11575	<li><i>Exact match</i>. Used to specify a single value for the given
11576	device attribute. Any string that doesn't start with <tt>int:</tt>
11577	represents the exact match. String device attributes are compared to
11578	this string including case of symbols. Integer attributes are first
11579	converted to a string (see individual filter attributes) and then
11580	compared ignoring case.
11581
11582	</li>
11583	<li><i>Any match</i>. Any value of the corresponding device attribute
11584	will match the given filter. An empty or @c null string is
11585	used to construct this type of filtering expressions.
11586
11587	</li>
11588	</ul>
11589
11590	<note>
11591	On the Windows host platform, interval filters are not currently
11592	available. Also all string filter attributes
11593	(<link to="#manufacturer"/>, <link to="#product"/>,
11594	<link to="#serialNumber"/>) are ignored, so they behave as
11595	<i>any match</i> no matter what string expression is specified.

11639	Note that for interval filters, it's best to use the hexadecimal

11704	of the USB device physically attached to the host computer regarding
11705	its state on the host computer and availability to guest computers
11706	(all currently running virtual machines).
11707
11708	Once a supported USB device is attached to the host, global USB
11709	filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
11710	either ignore the device, or put it to USBDeviceState_Held state, or do
11711	nothing. Unless the device is ignored by global filters, filters of all
11712	currently running guests (<link to="IUSBController::deviceFilters"/>) are
11713	activated that can put it to USBDeviceState_Captured state.
11714
11715	If the device was ignored by global filters, or didn't match
11716	any filters at all (including guest ones), it is handled by the host
11717	in a normal way. In this case, the device state is determined by
11718	the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
11719	or USBDeviceState_Available, depending on the current device usage.
11720
11721	Besides auto-capturing based on filters, the device can be manually
11722	captured by guests (<link to="IConsole::attachUSBDevice"/>) if its
11723	state is USBDeviceState_Busy, USBDeviceState_Available or
11724	USBDeviceState_Held.
11725
11726	<note>
11727	Due to differences in USB stack implementations in Linux and Win32,
11728	states USBDeviceState_Busy and USBDeviceState_vailable are applicable
11729	only to the Linux version of the product. This also means that (<link

12019	>
12020	<desc>
12021	The ISharedFolder interface represents a folder in the host computer's
12022	file system accessible from the guest OS running inside a virtual
12023	machine using an associated logical name.
12024
12025	There are three types of shared folders:
12026	<ul>
12027	<li><i>Global</i> (<link to="IVirtualBox::sharedFolders"/>), shared
12028	folders available to all virtual machines.</li>
12029	<li><i>Permanent</i> (<link to="IMachine::sharedFolders"/>),
12030	VM-specific shared folders available to the given virtual machine at
12031	startup.</li>
12032	<li><i>Transient</i> (<link to="IConsole::sharedFolders"/>),
12033	VM-specific shared folders created in the session context (for
12034	example, when the virtual machine is running) and automatically
12035	discarded when the session is closed (the VM is powered off).</li>
12036	</ul>
12037
12038	Logical names of shared folders must be unique within the given scope
12039	(global, permanent or transient). However, they do not need to be unique
12040	across scopes. In this case, the definition of the shared folder in a
12041	more specific scope takes precedence over definitions in all other
12042	scopes. The order of precedence is (more specific to more general):
12043	<ol>
12044	<li>Transient definitions</li>
12045	<li>Permanent definitions</li>
12046	<li>Global definitions</li>
12047	</ol>
12048
12049	For example, if MyMachine has a shared folder named
12050	<tt>C_DRIVE</tt> (that points to <tt>C:\\</tt>), then creating a
12051	transient shared folder named <tt>C_DRIVE</tt> (that points
12052	to <tt>C:\\\\WINDOWS</tt>) will change the definition
12053	of <tt>C_DRIVE</tt> in the guest OS so
12054	that <tt>\\\\VBOXSVR\\C_DRIVE</tt> will give access
12055	to <tt>C:\\WINDOWS</tt> instead of <tt>C:\\</tt> on the host
12056	PC. Removing the transient shared folder <tt>C_DRIVE</tt> will restore
12057	the previous (permanent) definition of <tt>C_DRIVE</tt> that points
12058	to <tt>C:\\</tt> if it still exists.
12059
12060	Note that permanent and transient shared folders of different machines
12061	are in different name spaces, so they don't overlap and don't need to
12062	have unique logical names.
12063
12064	<note>
12065	Global shared folders are not implemented in the current version of the
12066	product.

12470	<desc>
12471	The ISession interface represents a serialization primitive for virtual
12472	machines.
12473
12474	With VirtualBox, every time one wishes to manipulate a virtual machine
12475	(e.g. change its settings or start execution), a session object is
12476	required. Such an object must be passed to one of the session methods
12477	that open the given session, which then initiates the machine manipulation.
12478
12479	A session serves several purposes: it identifies to the inter-process VirtualBox
12480	code which process is currently working with the virtual machine, and it ensures
12481	that there are no incompatible requests from several processes for the
12482	same virtual machine. Session objects can therefore be thought of as mutex
12483	semaphores that lock virtual machines to prevent conflicting accesses from
12484	several processes.
12485
12486	How sessions objects are used depends on whether you use the Main API
12487	via COM or via the webservice:
12488
12489	<ul>
12490	<li>When using the COM API directly, an object of the Session class from the
12491	VirtualBox type library needs to be created. In regular COM C++ client code,
12492	this can be done by calling <tt>createLocalObject()</tt>, a standard COM API.
12493	This object will then act as a local session object in further calls to open
12494	a session.
12495	</li>
12496
12497	<li>In the webservice, the session manager (IWebsessionManager) instead creates
12498	one session object automatically when <link to="IWebsessionManager::logon" />
12499	is called. A managed object reference to that session object can be retrieved by
12500	calling <link to="IWebsessionManager::getSessionObject" />. This session object
12501	reference can then be used to open sessions.
12502	</li>
12503	</ul>
12504
12505	Sessions are mainly used in two variations:
12506
12507	<ul>
12508	<li>
12509	To start a virtual machine in a separate process, one would call
12510	<link to="IVirtualBox::openRemoteSession"/>, which requires a session
12511	object as its first parameter. This session then identifies the caller
12512	and lets him control the started machine (for example, pause machine
12513	execution or power it down) as well as be notified about machine
12514	execution state changes.
12515	</li>
12516
12517	<li>To alter machine settings, or to start machine execution within the
12518	current process, one needs to open a direct session for the machine first by
12519	calling <link to="IVirtualBox::openSession"/>. While a direct session
12520	is open within one process, no any other process may open another direct
12521	session for the same machine. This prevents the machine from being changed
12522	by other processes while it is running or while the machine is being configured.
12523	</li>
12524	</ul>
12525
12526	One also can attach to an existing direct session already opened by
12527	another process (for example, in order to send a control request to the
12528	virtual machine such as the pause or the reset request). This is done by
12529	calling <link to="IVirtualBox::openExistingSession"/>.
12530
12531	<note>
12532	Unless you are trying to write a new VirtualBox front-end that
12533	performs direct machine execution (like the VirtualBox or VBoxSDL
12534	front-ends), don't call <link to="IConsole::powerUp"/> in a direct
12535	session opened by <link to="IVirtualBox::openSession"/> and use this
12536	session only to change virtual machine settings. If you simply want to
12537	start virtual machine execution using one of the existing front-ends
12538	(for example the VirtualBox GUI or headless server), simply use
12539	<link to="IVirtualBox::openRemoteSession"/>; these front-ends
12540	will power up the machine automatically for you.

12568	It is recommended that every time an "open session" method (such as
12569	<link to="IVirtualBox::openRemoteSession" /> or
12570	<link to="IVirtualBox::openSession" />) has been called to
12571	manipulate a virtual machine, the caller invoke
12572	ISession::close() when it's done doing so. Since sessions are
12573	serialization primitives much like ordinary mutexes, they are
12574	best used the same way: for each "open" call, there should be
12575	a matching "close" call, even when errors occur.
12576
12577	Otherwise, if a direct session for a machine opened with
12578	<link to="IVirtualBox::openSession"/> is not explicitly closed
12579	when the application terminates, the state of the machine will
12580	be set to <link to="MachineState_Aborted" /> on the server.
12581
12582	Generally, it is recommended to close all open sessions explicitly
12583	before terminating the application (regardless of the reason for
12584	the termination).
12585
12586	<note>
12587	Do not expect the session state (<link to="ISession::state" />
12588	to return to "Closed" immediately after you invoke
12589	ISession::close(), particularly if you have started a remote
12590	session to execute the VM in a new process. The session state will
12591	automatically return to "Closed" once the VM is no longer executing,
12592	which can of course take a very long time.

12959	<desc>
12960	The IPerformanceCollector interface represents a service that collects and
12961	stores performance metrics data.
12962
12963	Performance metrics are associated with objects of interfaces like IHost and
12964	IMachine. Each object has a distinct set of performance metrics.
12965	The set can be obtained with <link to="IPerformanceCollector::getMetrics"/>.
12966
12967	Metric data is collected at the specified intervals and is retained
12968	internally. The interval and the number of retained samples can be set
12969	with <link to="IPerformanceCollector::setupMetrics" />.
12970
12971	Metrics are organized hierarchically, with each level separated by a
12972	slash (/) character. Generally, the scheme for metric names is like this:
12973
12974	<tt>Category/Metric[/SubMetric][:aggregation]</tt>
12975
12976	"Category/Metric" together form the base metric name. A base metric is the
12977	smallest unit for which a sampling interval and the number of retained
12978	samples can be set. Only base metrics can be enabled and disabled. All
12979	sub-metrics are collected when their base metric is collected.
12980	Collected values for any set of sub-metrics can be queried with
12981	<link to="IPerformanceCollector::queryMetricsData" />.
12982
12983	For example "CPU/Load/User:avg"
12984	metric name stands for the "CPU" category, "Load" metric, "User" submetric,
12985	"average" aggregate. An aggregate function is computed over all retained
12986	data. Valid aggregate functions are:
12987
12988	<ul>
12989	<li>avg -- average</li>
12990	<li>min -- minimum</li>
12991	<li>max -- maximum</li>
12992	</ul>
12993
12994	When setting up
12995	metric parameters, querying metric data, enabling or disabling metrics
12996	wildcards can be used in metric names to specify a subset of metrics. For
12997	example, to select all CPU-related metrics use <tt>CPU/*</tt>, all
12998	averages can be queried using <tt>*:avg</tt> and so on. To query metric
12999	values without aggregates <tt>*:</tt> can be used.
13000
13001	The valid names for base metrics are:
13002
13003	<ul>
13004	<li>CPU/Load</li>
13005	<li>CPU/MHz</li>
13006	<li>RAM/Usage</li>
13007	</ul>
13008
13009	The general sequence for collecting and retrieving the metrics is:
13010	<ul>
13011	<li>
13012	Obtain an instance of IPerformanceCollector with
13013	<link to="IVirtualBox::performanceCollector" />
13014	</li>
13015	<li>
13016	Allocate and populate an array with references to objects the metrics
13017	will be collected for. Use references to IHost and IMachine objects.
13018	</li>
13019	<li>
13020	Allocate and populate an array with base metric names the data will be
13021	collected for.
13022	</li>
13023	<li>
13024	Call <link to="IPerformanceCollector::setupMetrics" />. From now on the
13025	metric data will be collected and stored.
13026	</li>
13027	<li>
13028	Wait for the data to get collected.
13029	</li>
13030	<li>
13031	Allocate and populate an array with references to objects the metric
13032	values will be queried for. You can re-use the object array used for
13033	setting base metrics.
13034	</li>
13035	<li>
13036	Allocate and populate an array with metric names the data will be
13037	collected for. Note that metric names differ from base metric names.
13038	</li>
13039	<li>
13040	Call <link to="IPerformanceCollector::queryMetricsData" />. The data that
13041	have been collected so far are returned. Note that the values are still
13042	retained internally and data collection continues.
13043	</li>
13044	</ul>
