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.
284	</td>

484	Virtual machine execution state.
485
486	This enumeration represents possible values of the <link
487	to="IMachine::state"/> attribute.
488
489	Below is the basic virtual machine state diagram. It shows how the state
490	changes during virtual machine execution. The text in square braces shows
491	a method of the IConsole interface that performs the given state
492	transition.
493

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

1187	>
1188	<desc>
1189	The IVirtualBoxErrorInfo interface represents extended error information.
1190
1191	Extended error information can be set by VirtualBox components after
1192	unsuccessful or partially successful method invocation. This information
1193	can be retrieved by the calling party as an IVirtualBoxErrorInfo object
1194	and then shown to the client in addition to the plain 32-bit result code.
1195
1196	In MS COM, this interface extends the IErrorInfo interface,
1197	in XPCOM, it extends the nsIException interface. In both cases,
1198	it provides a set of common attributes to retrieve error
1199	information.
1200
1201	Sometimes invocation of some component's method may involve methods of
1202	other components that may also fail (independently of this method's
1203	failure), or a series of non-fatal errors may precede a fatal error that
1204	causes method failure. In cases like that, it may be desirable to preserve
1205	information about all errors happened during method invocation and deliver
1206	it to the caller. The <link to="#next"/> attribute is intended
1207	specifically for this purpose and allows to represent a chain of errors
1208	through a single IVirtualBoxErrorInfo object set after method invocation.
1209
1210	Note that errors are stored to a chain in the reverse order, i.e. the
1211	initial error object you query right after method invocation is the last
1212	error set by the callee, the object it points to in the @a next attribute
1213	is the previous error and so on, up to the first error (which is the last
1214	in the chain).

1219	Result code of the error.
1220	Usually, it will be the same as the result code returned
1221	by the method that provided this error information, but not
1222	always. For example, on Win32, CoCreateInstance() will most
1223	likely return E_NOINTERFACE upon unsuccessful component
1224	instantiation attempt, but not the value the component factory
1225	returned. Value is typed 'long', not 'result',
1226	to make interface usable from scripting languages.

1656	The IVirtualBox interface represents the main interface exposed by the
1657	product that provides virtual machine management.
1658
1659	An instance of IVirtualBox is required for the product to do anything
1660	useful. Even though the interface does not expose this, internally,
1661	IVirtualBox is implemented as a singleton and actually lives in the
1662	process of the VirtualBox server (VBoxSVC.exe). This makes sure that
1663	IVirtualBox can track the state of all virtual machines on a particular
1664	host, regardless of which frontend started them.

1786	<method name="createMachine">
1787	<desc>
1788	Creates a new virtual machine.
1789
1790	The new machine is created unregistered, with the initial configuration
1791	set according to the specified guest OS type. A typical sequence of
1792	actions to create a new virtual machine is as follows:
1793
1794	<ol>
1795	<li>
1796	Call this method to have a new machine created. The returned machine
1797	object will be "mutable" allowing to change any machine property.
1798	</li>
1799
1800	<li>
1801	Configure the machine using the appropriate attributes and methods.
1802	</li>
1803
1804	<li>
1805	Call <link to="IMachine::saveSettings" /> to write the settings
1806	to the machine's XML settings file. The configuration of the newly
1807	created machine will not be saved to disk until this method is
1808	called.
1809	</li>
1810
1811	<li>
1812	Call <link to="#registerMachine" /> to add the machine to the list
1813	of machines known to VirtualBox.
1814	</li>
1815	</ol>
1816
1817	You should specify valid name for the newly created machine when calling
1818	this method. See the <link to="IMachine::name"/> attribute description
1819	for more details about the machine name.
1820
1821	The specified guest OS type identifier must match an ID of one of known
1822	guest OS types listed in the <link to="IVirtualBox::guestOSTypes"/>
1823	array.
1824
1825	Every machine has a <i>settings file</i> that is used to store
1826	the machine configuration. This file is stored in a directory called the
1827	<i>machine settings subfolder</i>. Both the settings subfolder and file
1828	will have a name that corresponds to the name of the virtual machine.
1829	You can specify where to create the machine setting subfolder using the
1830	@a baseFolder argument. The base folder can be absolute (full path) or
1831	relative to the <link to="IVirtualBox::homeFolder">VirtualBox home
1832	directory</link>.
1833
1834	If @a baseFolder is a @c null or empty string (which is recommended), the
1835	<link to="ISystemProperties::defaultMachineFolder">default machine
1836	settings folder</link> will be used as a base folder for the created
1837	machine. Otherwise the given base folder will be used. In either case,
1838	the full path to the resulting settings file has the following
1839	structure:
1840	<pre>
1841	<base_folder>/<machine_name>/<machine_name>.xml
1842	</pre>
1843
1844	Note that if the resulting settings file already exists, this method
1845	will fail with <link to="VBOX_E_FILE_ERROR"/>.
1846
1847	Optionally, you may specify an UUID of to assign to the created machine.
1848	However, this is not recommended and you should normally pass an empty
1849	(@c null) UUID to this method so that a new UUID will be automatically
1850	generated for every created machine. You can use UUID
1851	00000000-0000-0000-0000-000000000000 as @c null value.
1852
1853	<note>
1854	There is no way to change the name of the settings file or
1855	subfolder of the created machine directly.

1900	default extension (.xml) will be appended.
1901
1902	Note that the configuration of the newly created machine is not
1903	saved to disk (and therefore no settings file is created)

2094	Creates a new base medium object that will use the given storage
2095	format and location for medium data.
2096
2097	Note that the actual storage unit is not created by this method. In
2098	order to do it, and before you are able to attach the created medium
2099	to virtual machines, you must call one of the following methods to
2100	allocate a format-specific storage unit at the specified location:
2101	<ul>
2102	<li><link to="IMedium::createBaseStorage"/></li>
2103	<li><link to="IMedium::createDiffStorage"/></li>
2104	</ul>
2105
2106	Some medium attributes, such as <link to="IMedium::id"/>, may
2107	remain uninitialized until the medium storage unit is successfully
2108	created by one of the above methods.
2109
2110	After the storage unit is successfully created, the medium gets
2111	remembered by this VirtualBox installation and will be accessible
2112	through <link to="#getHardDisk"/> and <link to="#findHardDisk"/>
2113	methods. Remembered base medium are also returned as part of
2114	the <link to="#hardDisks"/> array. See IMedium for more details.
2115
2116	The list of all storage formats supported by this VirtualBox
2117	installation can be obtained using
2118	<link to="ISystemProperties::mediumFormats"/>. If the @a format
2119	attribute is empty or @c null then the default storage format
2120	specified by <link to="ISystemProperties::defaultHardDiskFormat"/> will
2121	be used for creating a storage unit of the medium.
2122
2123	Note that the format of the location string is storage format specific.

2152	Opens a medium from an existing location, optionally replacing
2153	the image UUID and/or parent UUID.
2154
2155	After the medium is successfully opened by this method, it gets
2156	remembered by (known to) this VirtualBox installation and will be
2157	accessible through <link to="#getHardDisk"/> and
2158	<link to="#findHardDisk"/> methods. Remembered base media
2159	are also returned as part of the <link to="#hardDisks"/> array and can
2160	be attached to virtual machines. See IMedium for more details.
2161
2162	If a differencing medium is to be opened by this method, the
2163	operation will succeed only if its parent medium and all ancestors,
2164	if any, are already known to this VirtualBox installation (for example,
2165	were opened by this method before).
2166
2167	This method tries to guess the storage format of the specified medium
2168	by reading medium data at the specified location.
2169
2170	If @a write is ReadWrite (which it should be), the image is opened for
2171	read/write access and must have according permissions, as VirtualBox
2172	may actually write status information into the disk's metadata sections.
2173
2174	Note that write access is required for all typical image usage in VirtualBox,
2175	since VirtualBox may need to write metadata such as a UUID into the image.
2176	The only exception is opening a source image temporarily for copying and
2177	cloning when the image will quickly be closed again.
2178
2179	Note that the format of the location string is storage format specific.

2629	<method name="openSession">
2630	<desc>
2631	Opens a new direct session with the given virtual machine.
2632
2633	A direct session acts as a local lock on the given VM.
2634	There can be only one direct session open at a time for every
2635	virtual machine, protecting the VM from being manipulated by
2636	conflicting actions from different processes. Only after a
2637	direct session has been opened, one can change all VM settings
2638	and execute the VM in the process space of the session object.
2639
2640	Sessions therefore can be compared to mutex semaphores that
2641	lock a given VM for modification and execution.
2642	See <link to="ISession">ISession</link> for details.
2643
2644	<note>Unless you are writing a new VM frontend, you will not
2645	want to execute a VM in the current process. To spawn a new
2646	process that executes a VM, use
2647	<link to="IVirtualBox::openRemoteSession" />
2648	instead.</note>
2649
2650	Upon successful return, the session object can be used to
2651	get access to the machine and to the VM console.
2652
2653	In VirtualBox terminology, the machine becomes "mutable" after
2654	a session has been opened. Note that the "mutable" machine
2655	object, on which you may invoke IMachine methods to change its
2656	settings, will be a different object from the immutable IMachine
2657	objects returned by various IVirtualBox methods. To obtain a
2658	mutable IMachine object (upon which you can invoke settings methods),
2659	use the <link to="ISession::machine" /> attribute.
2660
2661	One must always call <link to="ISession::close" /> to release the
2662	lock on the machine, or the machine's state will eventually be
2663	set to "Aborted".
2664
2665	In other words, to change settings on a machine, the following
2666	sequence is typically performed:
2667
2668	<ol>
2669	<li>Call this method (openSession) to have a machine locked for
2670	the current session.</li>
2671
2672	<li>Obtain a mutable IMachine object from <link to="ISession::machine" />.</li>
2673
2674	<li>Change the settings of the machine.</li>
2675
2676	<li>Call <link to="IMachine::saveSettings" />.</li>
2677
2678	<li>Close the session by calling <link to="ISession::close"/>.</li>

2714	<method name="openRemoteSession">
2715	<desc>
2716	Spawns a new process that executes a virtual machine (called a
2717	"remote session").
2718
2719	Opening a remote session causes the VirtualBox server to start a new
2720	process that opens a direct session with the given VM. As a result, the
2721	VM is locked by that direct session in the new process, preventing
2722	conflicting changes from other processes. Since sessions act as locks
2723	that prevent conflicting changes, one cannot open a remote session
2724	for a VM that already has another open session (direct or remote), or
2725	is currently in the process of opening one (see <link
2726	to="IMachine::sessionState"/>).
2727
2728	While the remote session still provides some level of control over the
2729	VM execution to the caller (using the <link to="IConsole" /> interface),
2730	not all VM settings are available for modification within the remote
2731	session context.
2732
2733	This operation can take some time (a new VM is started in a new process,
2734	for which memory and other resources need to be set up). Because of this,
2735	an <link to="IProgress" /> is returned to allow the caller to wait for this
2736	asynchronous operation to be completed. Until then, the remote session
2737	object remains in the closed state, and accessing the machine or its
2738	console through it is invalid. It is recommended to use
2739	<link to="IProgress::waitForCompletion" /> or similar calls to wait for
2740	completion. Completion is signalled when the VM is powered on. Error
2741	messages etc. can be queried via the progress object, if available.
2742
2743	As with all <link to="ISession" /> objects, it is recommended to call
2744	<link to="ISession::close" /> on the local session object once openRemoteSession()
2745	has been called. However, the session's state (see <link to="ISession::state" />)
2746	will not return to "Closed" until the remote session has also closed (i.e.
2747	until the VM is no longer running). In that case, however, the state of
2748	the session will automatically change back to "Closed".
2749
2750	Currently supported session types (values of the @a type
2751	argument) are:
2752	<ul>
2753	<li><tt>"gui"</tt>: VirtualBox Qt GUI session</li>
2754	<li><tt>"vrdp"</tt>: VirtualBox VRDP Server session</li>
2755	<li><tt>"sdl"</tt>: VirtualBox SDL GUI session</li>
2756	</ul>
2757
2758	The @a environment argument is a string containing definitions of
2759	environment variables in the following format:
2760	@code
2761	NAME[=VALUE]\n
2762	NAME[=VALUE]\n
2763	...
2764	@endcode
2765	where <tt>\\n</tt> is the new line character. These environment
2766	variables will be appended to the environment of the VirtualBox server
2767	process. If an environment variable exists both in the server process
2768	and in this list, the value from this list takes precedence over the
2769	server's variable. If the value of the environment variable is
2770	omitted, this variable will be removed from the resulting environment.
2771	If the environment string is @c null or empty, the server environment
2772	is inherited by the started process as is.

2906	Blocks the caller until any of the properties represented by the
2907	@a what argument changes the value or until the given timeout interval
2908	expires.
2909
2910	The @a what argument is a comma separated list of property masks that
2911	describe properties the caller is interested in. The property mask is
2912	a string in the following format:
2913
2914	<pre>
2915	[[group.]subgroup.]name
2916	</pre>
2917
2918	where @c name is the property name and @c group, @c subgroup are zero
2919	or more property group specifiers. Each element (group or name) in
2920	the property mask may be either a Latin string or an asterisk symbol
2921	(@c "*") which is used to match any string for the given element. A
2922	property mask that doesn't contain asterisk symbols represents a
2923	single fully qualified property name.
2924
2925	Groups in the fully qualified property name go from more generic (the
2926	left-most part) to more specific (the right-most part). The first
2927	element is usually a name of the object the property belongs to. The
2928	second element may be either a property name, or a child object name,
2929	or an index if the preceding element names an object which is one of
2930	many objects of the same type. This way, property names form a
2931	hierarchy of properties. Here are some examples of property names:
2932
2933	<table>
2934	<tr>
2935	<td><tt>VirtualBox.version</tt></td>
2936	<td><link to="IVirtualBox::version"/> property</td>
2937	</tr>
2938	<tr>
2939	<td><tt>Machine.<UUID>.name</tt></td>
2940	<td><link to="IMachine::name"/> property of the machine with the
2941	given UUID</td>
2942	</tr>
2943	</table>
2944
2945	Most property names directly correspond to the properties of objects
2946	(components) provided by the VirtualBox library and may be used to
2947	track changes to these properties. However, there may be
2948	pseudo-property names that don't correspond to any existing object's
2949	property directly, as well as there may be object properties that
2950	don't have a corresponding property name that is understood by this
2951	method, and therefore changes to such properties cannot be
2952	tracked. See individual object's property descriptions to get a
2953	fully qualified property name that can be used with this method (if
2954	any).
2955
2956	There is a special property mask @c "*" (i.e. a string consisting of a
2957	single asterisk symbol) that can be used to match all properties.
2958	Below are more examples of property masks:
2959
2960	<table>
2961	<tr>
2962	<td><tt>VirtualBox.*</tt></td>
2963	<td>Track all properties of the VirtualBox object</td>
2964	</tr>
2965	<tr>

3246	Represents a platform-independent appliance in OVF format. An instance of this is returned
3247	by <link to="IVirtualBox::createAppliance" />, which can then be used to import and export
3248	appliances with VirtualBox.
3249
3250	The OVF standard suggests two different physical file formats:
3251
3252	<ol>
3253	<li>If the OVF is distributed as a set of files, then @a file must be a fully qualified
3254	path name to an existing OVF descriptor file with an <tt>.ovf</tt> file extension. If
3255	this descriptor file references other files, as OVF appliances distributed as a set of
3256	files most likely do, those files must be in the same directory as the descriptor file.</li>
3257
3258	<li>If the OVF is distributed as a single file, it must be in TAR format and have the
3259	<tt>.ova</tt> file extension. This TAR file must then contain at least the OVF descriptor
3260	files and optionally other files.
3261
3262	At this time, VirtualBox does not not yet support the packed (TAR) variant; support will
3263	be added with a later version.</li>
3264	</ol>
3265
3266	<b>Importing</b> an OVF appliance into VirtualBox as instances of
3267	<link to="IMachine" /> involves the following sequence of API calls:
3268
3269	<ol>
3270	<li>Call <link to="IVirtualBox::createAppliance" />. This will create an empty IAppliance object.
3271	</li>
3272
3273	<li>On the new object, call <link to="#read" /> with the full path of the OVF file you
3274	would like to import. So long as this file is syntactically valid, this will succeed
3275	and return an instance of IAppliance that contains the parsed data from the OVF file.
3276	</li>
3277
3278	<li>Next, call <link to="#interpret" />, which analyzes the OVF data and sets up the
3279	contents of the IAppliance attributes accordingly. These can be inspected by a
3280	VirtualBox front-end such as the GUI, and the suggestions can be displayed to the
3281	user. In particular, the <link to="#virtualSystemDescriptions" /> array contains
3282	instances of <link to="IVirtualSystemDescription" /> which represent the virtual
3283	systems in the OVF, which in turn describe the virtual hardware prescribed by the
3284	OVF (network and hardware adapters, virtual disk images, memory size and so on).
3285	The GUI can then give the user the option to confirm and/or change these suggestions.
3286	</li>
3287
3288	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
3289	virtual system to override the suggestions made by the interpret() routine.
3290	</li>
3291
3292	<li>Finally, call <link to="#importMachines" /> to create virtual machines in
3293	VirtualBox as instances of <link to="IMachine" /> that match the information in the
3294	virtual system descriptions.
3295	</li>
3296	</ol>
3297
3298	<b>Exporting</b> VirtualBox machines into an OVF appliance involves the following steps:
3299
3300	<ol>
3301	<li>As with importing, first call <link to="IVirtualBox::createAppliance" /> to create
3302	an empty IAppliance object.
3303	</li>
3304
3305	<li>For each machine you would like to export, call <link to="IMachine::export" />
3306	with the IAppliance object you just created. This creates an instance of
3307	<link to="IVirtualSystemDescription" /> inside the appliance.
3308	</li>
3309
3310	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
3311	virtual system to override the suggestions made by the export() routine.
3312	</li>
3313
3314	<li>Finally, call <link to="#write" /> with a path specification to have the OVF
3315	file written.</li>
3316	</ol>
3317
3318	</desc>
3319
3320	<attribute name="path" type="wstring" readonly="yes">
3321	<desc>Path to the main file of the OVF appliance, which is either the <tt>.ovf</tt> or

3334	The caller should be prepared for additional fields being appended to
3335	this string in future versions of VirtualBox and therefore check for
3336	the number of tabs in the strings returned.

3599	"HarddiskControllerSCSI": a SCSI hard disk controller. There can be at most one such item.
3600	The items in aOvfValues[] and aVBoxValues[] will either be "LsiLogic" or "BusLogic".
3601	The matching item in the aRefs[] array will be used as with IDE controllers (see above).
3602	</li>
3603	<li>
3604	"HardDiskImage": a virtual hard disk, most probably as a reference to an image file. There can be an
3605	arbitrary number of these items, one for each virtual disk image that accompanies the OVF.
3606
3607	The array item in aOvfValues[] will contain the file specification from the OVF file (without
3608	a path since the image file should be in the same location as the OVF file itself), whereas the
3609	item in aVBoxValues[] will contain a qualified path specification to where VirtualBox uses the
3610	hard disk image. This means that on import the image will be copied and converted from the
3611	"ovf" location to the "vbox" location; on export, this will be handled the other way round.
3612	On import, the target image will also be registered with VirtualBox.
3613
3614	The matching item in the aExtraConfigValues[] array must contain a string of the following
3615	format: "controller=<index>;channel=<c>"
3616	In this string, <index> must be an integer specifying the hard disk controller to connect
3617	the image to. That number must be the index of an array item with one of the hard disk controller
3618	types (HarddiskControllerSCSI, HarddiskControllerSATA, HarddiskControllerIDE).
3619	In addition, <c> must specify the channel to use on that controller. For IDE controllers,
3620	this can range from 0-3 (which VirtualBox will interpret as primary master, primary slave, secondary master and
3621	secondary slave. For SATA and SCSI controllers, the channel can range from 0-29.
3622	</li>
3623	<li>
3624	"CDROM": a virtual CD-ROM drive. The matching item in aExtraConfigValue[] contains the same
3625	attachment information as with "HardDiskImage" items.
3626	</li>
3627	<li>
3628	"CDROM": a virtual floppy drive. The matching item in aExtraConfigValue[] contains the same
3629	attachment information as with "HardDiskImage" items.
3630	</li>
3631	<li>
3632	"NetworkAdapter": a network adapter. The array item in aVBoxValues[] will specify the hardware
3633	for the network adapter, whereas the array item in aExtraConfigValues[] will have a string
3634	of the "type=<X>" format, where <X> must be either "NAT" or "Bridged".
3635	</li>
3636	<li>
3637	"USBController": a USB controller. There can be at most one such item. If and only if such an
3638	item ispresent, USB support will be enabled for the new virtual machine.
3639	</li>
3640	<li>
3641	"SoundCard": a sound card. There can be at most one such item. If and only if such an item is
3642	present, sound support will be enabled for the new virtual machine. Note that the virtual
3643	machine in VirtualBox will always be presented with the standard VirtualBox soundcard, which
3644	may be different from the virtual soundcard expected by the appliance.

4232	<desc>
4233	The IMachine interface represents a virtual machine, or guest, created
4234	in VirtualBox.
4235
4236	This interface is used in two contexts. First of all, a collection of
4237	objects implementing this interface is stored in the
4238	<link to="IVirtualBox::machines"/> attribute which lists all the virtual
4239	machines that are currently registered with this VirtualBox
4240	installation. Also, once a session has been opened for the given virtual
4241	machine (e.g. the virtual machine is running), the machine object
4242	associated with the open session can be queried from the session object;
4243	see <link to="ISession"/> for details.
4244
4245	The main role of this interface is to expose the settings of the virtual
4246	machine and provide methods to change various aspects of the virtual
4247	machine's configuration. For machine objects stored in the
4248	<link to="IVirtualBox::machines"/> collection, all attributes are
4249	read-only unless explicitly stated otherwise in individual attribute
4250	and method descriptions. In order to change a machine setting, a session
4251	for this machine must be opened using one of
4252	<link to="IVirtualBox::openSession"/>,
4253	<link to="IVirtualBox::openRemoteSession"/> or
4254	<link to="IVirtualBox::openExistingSession"/> methods. After the
4255	session has been successfully opened, a mutable machine object needs to
4256	be queried from the session object and then the desired settings changes
4257	can be applied to the returned object using IMachine attributes and
4258	methods. See the <link to="ISession"/> interface description for more
4259	information about sessions.
4260
4261	Note that IMachine does not provide methods to control virtual machine
4262	execution (such as start the machine, or power it down) -- these methods
4263	are grouped in a separate interface called <link to="IConsole" />.

4271
4272	<attribute name="accessible" type="boolean" readonly="yes">
4273	<desc>
4274	Whether this virtual machine is currently accessible or not.
4275
4276	A machine is always deemed accessible unless it is registered <i>and</i>
4277	its settings file cannot be read or parsed (either because the file itself
4278	is unavailable or has invalid XML contents).
4279
4280	Every time this property is read, the accessibility state of
4281	this machine is re-evaluated. If the returned value is @c false,
4282	the <link to="#accessError"/> property may be used to get the
4283	detailed error information describing the reason of
4284	inaccessibility, including XML error messages.
4285
4286	When the machine is inaccessible, only the following properties
4287	can be used on it:
4288	<ul>
4289	<li><link to="#parent"/></li>
4290	<li><link to="#id"/></li>
4291	<li><link to="#settingsFilePath"/></li>
4292	<li><link to="#accessible"/></li>
4293	<li><link to="#accessError"/></li>
4294	</ul>
4295
4296	An attempt to access any other property or method will return
4297	an error.
4298
4299	The only possible action you can perform on an inaccessible
4300	machine is to unregister it using the
4301	<link to="IVirtualBox::unregisterMachine"/> call (or, to check
4302	for the accessibility state once more by querying this
4303	property).
4304
4305	<note>
4306	In the current implementation, once this property returns
4307	@c true, the machine will never become inaccessible
4308	later, even if its settings file cannot be successfully
4309	read/written any more (at least, until the VirtualBox
4310	server is restarted). This limitation may be removed in
4311	future releases.

4319	inaccessibility.
4320
4321	Reading this property is only valid after the last call to
4322	<link to="#accessible"/> returned @c false (i.e. the
4323	machine is currently unaccessible). Otherwise, a @c null
4324	IVirtualBoxErrorInfo object will be returned.

4328	<attribute name="name" type="wstring">
4329	<desc>
4330	Name of the virtual machine.
4331
4332	Besides being used for human-readable identification purposes
4333	everywhere in VirtualBox, the virtual machine name is also used
4334	as a name of the machine's settings file and as a name of the
4335	subdirectory this settings file resides in. Thus, every time you
4336	change the value of this property, the settings file will be
4337	renamed once you call <link to="#saveSettings"/> to confirm the
4338	change. The containing subdirectory will be also renamed, but
4339	only if it has exactly the same name as the settings file
4340	itself prior to changing this property (for backward compatibility
4341	with previous API releases). The above implies the following
4342	limitations:
4343	<ul>
4344	<li>The machine name cannot be empty.</li>
4345	<li>The machine name can contain only characters that are valid
4346	file name characters according to the rules of the file
4347	system used to store VirtualBox configuration.</li>
4348	<li>You cannot have two or more machines with the same name
4349	if they use the same subdirectory for storing the machine
4350	settings files.</li>
4351	<li>You cannot change the name of the machine if it is running,
4352	or if any file in the directory containing the settings file
4353	is being used by another running machine or by any other
4354	process in the host operating system at a time when
4355	<link to="#saveSettings"/> is called.
4356	</li>
4357	</ul>
4358	If any of the above limitations are hit, <link to="#saveSettings"/>
4359	will return an appropriate error message explaining the exact
4360	reason and the changes you made to this machine will not be
4361	saved.
4362	<note>
4363	For "legacy" machines created using the
4364	<link to="IVirtualBox::createLegacyMachine"/> call,
4365	the above naming limitations do not apply because the
4366	machine name does not affect the settings file name.
4367	The settings file name remains the same as it was specified
4368	during machine creation and never changes.

4836	Attaches a device and optionally mounts a medium to the given storage
4837	controller (<link to="IStorageController" />, identified by @a name),
4838	at the indicated port and device.
4839
4840	This method is intended for managing storage devices in general (it works
4841	for both fixed and removable media). For storage devices supporting removable
4842	media (such as DVDs and floppies), you can also use <link to="IMedium::mountMedium"/>
4843	for changing the media while the machine is running.
4844
4845	For the IDE bus, the @a controllerPort parameter can be either
4846	@c 0 or @c 1, to specify the primary or secondary IDE controller,
4847	respectively. For each of these, @a device can then be either @c 0 or @c 1,
4848	to specify the master or the slave device, respectively. (In the
4849	default configuration of virtual machines, the secondary master is
4850	used for a CD/DVD drive.)
4851
4852	For an SATA controller, @a controllerPort must be a number ranging
4853	from @c 0 to @c 29. For a SCSI controller, @a controllerPort must
4854	be a number ranging from @c 0 to @c 15.
4855
4856	For both SCSI and SATA, the @a device parameter is unused and must
4857	be @c 0.
4858
4859	For fixed media such as hard disks, the given medium identifier cannot
4860	be a zero UUID. It may be a zero UUID for removable media such as DVDs
4861	and floppies.
4862
4863	After calling this returns successfully, a new instance of
4864	<link to="IMediumAttachment"/> will appear in the machine's list of medium
4865	attachments (<link to="IMachine::mediumAttachments"/>).
4866
4867	The specified device slot must not have a device attached to it,
4868	or this method will fail.

4877	</note>
4878	<note>
4879	If the medium is being attached indirectly, a new differencing medium
4880	will implicitly be created for it and attached instead. If the

6073	This interface is used by a client of the Main API that need to
6074	be notified of events. For example, a graphical user interface
6075	can use this to learn about machine state changes so they can
6076	update the list of virtual machines without having to rely
6077	on polling.
6078
6079	Whenever relevant events occur in VirtualBox, the callbacks in
6080	objects of this interface are called. In order for this to be
6081	useful, a client needs to create its own subclass that implements
6082	this interface in which the methods for the relevant callbacks
6083	are overridden. An instance of this subclass interface can then

6126	The @a shape buffer contains a 1-bpp (bits per pixel) AND mask

6128
6129	For pointers without alpha channel the XOR mask pixels are 32

6131	the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
6132
6133	An AND mask is used for pointers with alpha channel, so if the
6134	callback does not support alpha, the pointer could be
6135	displayed as a normal color pointer.
6136
6137	The AND mask is a 1-bpp bitmap with byte aligned scanlines. The
6138	size of the AND mask therefore is <tt>cbAnd = (width + 7) / 8 *
6139	height</tt>. The padding bits at the end of each scanline are
6140	undefined.
6141
6142	The XOR mask follows the AND mask on the next 4-byte aligned
6143	offset: <tt>uint8_t *pXor = pAnd + (cbAnd + 3) & ~3</tt>.
6144	Bytes in the gap between the AND and the XOR mask are undefined.
6145	The XOR mask scanlines have no gap between them and the size of
6146	the XOR mask is: <tt>cXor = width * 4 * height</tt>.

6339	<desc>
6340	Notification when an error happens during the virtual
6341	machine execution.
6342
6343	There are three kinds of runtime errors:
6344	<ul>
6345	<li><i>fatal</i></li>
6346	<li><i>non-fatal with retry</i></li>
6347	<li><i>non-fatal warnings</i></li>
6348	</ul>
6349
6350	<b>Fatal</b> errors are indicated by the @a fatal parameter set
6351	to @c true. In case of fatal errors, the virtual machine
6352	execution is always paused before calling this notification, and
6353	the notification handler is supposed either to immediately save
6354	the virtual machine state using <link to="IConsole::saveState"/>
6355	or power it off using <link to="IConsole::powerDown"/>.
6356	Resuming the execution can lead to unpredictable results.
6357
6358	<b>Non-fatal</b> errors and warnings are indicated by the
6359	@a fatal parameter set to @c false. If the virtual machine
6360	is in the Paused state by the time the error notification is
6361	received, it means that the user can <i>try to resume</i> the machine
6362	execution after attempting to solve the problem that caused the
6363	error. In this case, the notification handler is supposed
6364	to show an appropriate message to the user (depending on the
6365	value of the @a id parameter) that offers several actions such
6366	as <i>Retry</i>, <i>Save</i> or <i>Power Off</i>. If the user
6367	wants to retry, the notification handler should continue
6368	the machine execution using the <link to="IConsole::resume"/>
6369	call. If the machine execution is not Paused during this
6370	notification, then it means this notification is a <i>warning</i>
6371	(for example, about a fatal condition that can happen very soon);
6372	no immediate action is required from the user, the machine
6373	continues its normal execution.
6374
6375	Note that in either case the notification handler
6376	<b>must not</b> perform any action directly on a thread
6377	where this notification is called. Everything it is allowed to
6378	do is to post a message to another thread that will then talk
6379	to the user and take the corresponding action.
6380
6381	Currently, the following error identifiers are known:
6382	<ul>
6383	<li><tt>"HostMemoryLow"</tt></li>
6384	<li><tt>"HostAudioNotResponding"</tt></li>
6385	<li><tt>"VDIStorageFull"</tt></li>

6449
6450	Note that many modern window managers on many platforms

6452	that it may be impossible to activate a window without the
6453	help of the currently active application (which is supposedly
6454	an initiator of this notification). In this case, this method
6455	must return a non-zero identifier that represents the
6456	top-level window of the VM console process. The caller, if it
6457	represents a currently active process, is responsible to use
6458	this identifier (in a platform-dependent manner) to perform
6459	actual window activation.
6460
6461	This method must set @a winId to zero if it has performed all
6462	actions necessary to complete the request and the console
6463	window is now active and in foreground, to indicate that no
6464	further action is required on the caller's side.

7154	See <link to="ISnapshot" /> for an introduction to snapshots.
7155
7156	The execution state and settings of the associated machine stored in
7157	the snapshot will be deleted. The contents of all differencing media of
7158	this snapshot will be merged with the contents of their dependent child
7159	media to keep the medium chain valid (in other words, all changes
7160	represented by media being discarded will be propagated to their child
7161	medium). After that, this snapshot's differencing medium will be
7162	deleted. The parent of this snapshot will become a new parent for all
7163	its child snapshots.
7164
7165	If the deleted snapshot is the current one, its parent snapshot will
7166	become a new current snapshot. The current machine state is not directly
7167	affected in this case, except that currently attached differencing
7168	media based on media of the discarded snapshot will be also merged as
7169	described above.
7170
7171	If the deleted snapshot is the first or current snapshot, then the
7172	respective IMachine attributes will be adjusted. Deleting the current
7173	snapshot will also implicitly call <link to="IMachine::saveSettings"/>
7174	to make all current machine settings permanent.
7175
7176	Deleting a snapshot has the following preconditions:
7177
7178	<ul>
7179	<li>Child media of all normal media of the discarded snapshot
7180	must be accessible (see <link to="IMedium::state"/>) for this
7181	operation to succeed. In particular, this means that all virtual
7182	machines, whose media are directly or indirectly based on the
7183	media of discarded snapshot, must be powered off.</li>
7184
7185	<li>You cannot delete the snapshot if a medium attached to it has
7186	more than once child medium (differencing images) because otherwise
7187	merging would be impossible. This might be the case if there is
7188	more than one child snapshot or differencing images were created
7189	for other reason (e.g. implicitly because of multiple machine
7190	attachments).</li>
7191	</ul>
7192
7193
7194	The virtual machine's <link to="IMachine::state">state</link> is changed to "DeletingSnapshot"
7195	while this operation is in progress.
7196
7197	<note>
7198	Merging medium contents can be very time and disk space
7199	consuming, if these media are big in size and have many
7200	children. However, if the snapshot being discarded is the last
7201	(head) snapshot on the branch, the operation will be rather
7202	quick.

8094	refer to the same medium format.

8108	Identifier of the default medium format used by VirtualBox.
8109
8110	The medium format set by this attribute is used by VirtualBox
8111	when the medium format was not specified explicitly. One example is
8112	<link to="IVirtualBox::createHardDisk"/> with the empty
8113	format argument. A more complex example is implicit creation of
8114	differencing media when taking a snapshot of a virtual machine:
8115	this operation will try to use a format of the parent medium first
8116	and if this format does not support differencing media the default
8117	format specified by this argument will be used.
8118
8119	The list of supported medium formats may be obtained by the
8120	<link to="#mediaFormats"/> call. Note that the default medium
8121	format must have a capability to create differencing media;
8122	otherwise operations that create media implicitly may fail
8123	unexpectedly.

8146
8147	The system library extension (".DLL" or ".so") must be omitted.
8148	A full path can be specified; if not, then the library must reside on the
8149	system's default library path.

8170
8171	As opposed to <link to="ISystemProperties::remoteDisplayAuthLibrary" />,
8172	there is no per-VM setting for this, as the webservice is a global
8173	resource (if it is running). Only for this setting (for the webservice),
8174	setting this value to a literal <tt>"null"</tt> string disables authentication,
8175	meaning that <link to="IWebsessionManager::logon" /> will always succeed,
8176	no matter what user name and password are supplied.
8177
8178	The initial value of this property is <tt>"VRDPAuth"</tt>,
8179	meaning that the webservice will use the same authentication
8180	library that is used by default for VBoxVRDP (again, see
8181	<link to="ISystemProperties::remoteDisplayAuthLibrary" />).
8182	The format and calling convention of authentication libraries
8183	is the same for the webservice as it is for VBoxVRDP.

8479	<desc>
8480	The IProgress interface is used to track and control
8481	asynchronous tasks within VirtualBox.
8482
8483	An instance of this is returned every time VirtualBox starts
8484	an asynchronous task (in other words, a separate thread) which
8485	continues to run after a method call returns. For example,
8486	<link to="IConsole::saveState" />, which saves the state of
8487	a running virtual machine, can take a long time to complete.
8488	To be able to display a progress bar, a user interface such as
8489	the VirtualBox graphical user interface can use the IProgress
8490	object returned by that method.
8491
8492	Note that IProgress is a "read-only" interface in the sense
8493	that only the VirtualBox internals behind the Main API can
8494	create and manipulate progress objects, whereas client code
8495	can only use the IProgress object to monitor a task's
8496	progress and, if <link to="#cancelable" /> is @c true,
8497	cancel the task by calling <link to="#cancel" />.
8498
8499	A task represented by IProgress consists of either one or
8500	several sub-operations that run sequentially, one by one (see
8501	<link to="#operation" /> and <link to="#operationCount" />).
8502	Every operation is identified by a number (starting from 0)
8503	and has a separate description.
8504
8505	You can find the individual percentage of completion of the current
8506	operation in <link to="#operationPercent" /> and the
8507	percentage of completion of the task as a whole
8508	in <link to="#percent" />.
8509
8510	Similarly, you can wait for the completion of a particular
8511	operation via <link to="#waitForOperationCompletion" /> or
8512	for the completion of the whole task via
8513	<link to="#waitForCompletion" />.

8546

8683	wsmap="managed"
8684	>
8685	<desc>
8686	The ISnapshot interface represents a snapshot of the virtual
8687	machine.
8688
8689	Together with the differencing media that are created
8690	when a snapshot is taken, a machine can be brought back to
8691	the exact state it was in when the snapshot was taken.
8692
8693	The ISnapshot interface has no methods, only attributes; snapshots
8694	are controlled through methods of the <link to="IConsole" /> interface
8695	which also manage the media associated with the snapshot.
8696	The following operations exist:
8697
8698	<ul>
8699	<li><link to="IConsole::takeSnapshot"/>: creates a new snapshot
8700	by creating new, empty differencing images for the machine's
8701	media and saving the VM settings and (if the VM is running)
8702	the current VM state in the snapshot.
8703
8704	The differencing images will then receive all data written to
8705	the machine's media, while their parent (base) images
8706	remain unmodified after the snapshot has been taken (see
8707	<link to="IMedium" /> for details about differencing images).
8708	This simplifies restoring a machine to the state of a snapshot:
8709	only the differencing images need to be deleted.
8710
8711	The current machine state is not changed by taking a snapshot.
8712	If the machine is running, it will resume execution after the
8713	snapshot has been taken.
8714	</li>
8715
8716	<li><link to="IConsole::restoreSnapshot"/>: this goes back to
8717	a previous snapshot. This resets the machine's state to that of
8718	the previous snapshot by deleting the differencing image of each
8719	of the machine's media and setting the machine's settings
8720	and state to the state that was saved in the snapshot (if any).
8721
8722	This destroys the machine's current state.
8723	</li>
8724
8725	<li><link to="IConsole::deleteSnapshot"/>: deletes a snapshot
8726	without affecting the current machine state.
8727
8728	This does not change the machine, but instead frees the resources
8729	allocated when the snapshot was taken: the settings and machine state
8730	is deleted (if any), and the snapshot's differencing image for each
8731	of the machine's media gets merged with its parent image.
8732
8733	Neither the current machine state nor other snapshots are affected
8734	by this operation, except that parent media will be modified
8735	to contain the disk data associated with the snapshot being deleted.
8736	</li>
8737	</ul>
8738
8739	Each snapshot contains the settings of the virtual machine (hardware
8740	configuration etc.). In addition, if the machine was running when the
8741	snapshot was taken (<link to="IMachine::state"/> is <link to="MachineState_Running"/>),
8742	the current VM state is saved in the snapshot (similarly to what happens
8743	when a VM's state is saved). The snapshot is then said to
8744	be <i>online</i> because when restoring it, the VM will be running.
8745
8746	If the machine is saved (<link to="MachineState_Saved"/>), the snapshot
8747	receives a copy of the execution state file (<link to="IMachine::stateFilePath"/>).
8748
8749	Otherwise, if the machine was not running (<link to="MachineState_PoweredOff"/>
8750	or <link to="MachineState_Aborted"/>), the snapshot is <i>offline</i>;
8751	it then contains a so-called "zero execution state", representing a
8752	machine that is powered off.
8753
8754	<h3>Snapshot branches and the "current" snapshot</h3>
8755
8756	Snapshots can be chained, whereby every next snapshot is based on the
8757	previous one. This chaining is related to medium branching
8758	(see the <link to="IMedium"/> description) in that every time
8759	a new snapshot is created, a new differencing medium is implicitly
8760	created for all normal media attached to the machine.
8761
8762	Each virtual machine has a "current snapshot", identified by
8763	<link to="IMachine::currentSnapshot"/>. Presently, this is always set
8764	to the last snapshot in the chain. In a future version of VirtualBox,
8765	it will be possible to reset a machine's current state to that of an
8766	earlier snapshot without discarding the current state so that it will be
8767	possible to create alternative snapshot paths in a snapshot tree.
8768
8769	In the current implementation, multiple snapshot branches within one
8770	virtual machine are not allowed. Every machine has a single branch,
8771	and <link to="IConsole::takeSnapshot"/> operation adds a new
8772	snapshot to the top of that branch.

8968	The IMediumAttachment interface represents the attachment
8969	of a storage medium to a virtual machine. Each machine contains
8970	an array of its medium attachments in <link to="IMachine::mediumAttachments"/>.
8971
8972	Each medium attachment specifies a storage controller as well as a port
8973	and device number. Fixed media (hard disks) will always also specify
8974	an instance of IMedium in <link to="#medium" />, referring to the hard disk
8975	medium. For removeable media, the IMedia instance is optional; it can be

9013	<desc>
9014	The IMedium interface represents virtual storage for a machine's
9015	hard disks, CD/DVD or floppy drives. It will typically represent
9016	a disk image on the host, for example a VDI or VMDK file representing
9017	a virtual hard disk, or an ISO or RAW file representing virtual
9018	removable media, but can also point to a network location (e.g.
9019	for iSCSI targets).
9020
9021	Instances of IMedium are connected to virtual machines by way of
9022	medium attachments (see <link to="IMediumAttachment" />), which link
9023	the storage medium to a particular device slot of a storage controller
9024	of the virtual machine.
9025	In the VirtualBox API, virtual storage is therefore always represented
9026	by the following chain of object links:
9027
9028	<ul>
9029	<li><link to="IMachine::storageControllers"/> contains an array of
9030	storage controllers (IDE, SATA, SCSI or a floppy controller;
9031	these are instances of <link to="IStorageController"/>).</li>
9032	<li><link to="IMachine::mediumAttachments"/> contains an array of
9033	medium attachments (instances of <link to="IMediumAttachment"/>),
9034	each containing a storage controller from the above array, a
9035	port/device specification, and an instance of IMedium representing
9036	the medium storage (image file).
9037
9038	For removable media, the storage medium is optional; a medium
9039	attachment with no medium represents a CD/DVD or floppy drive
9040	with no medium inserted. By contrast, hard disk attachments
9041	will always have an IMedium object attached.</li>
9042	<li>Each IMedium in turn points to a storage unit (such as a file
9043	on the host computer or a network resource) that holds actual
9044	data. This location is represented by the <link to="#location"/>
9045	attribute.</li>
9046	</ul>
9047
9048	Existing media are opened using the following methods, depending on the
9049	media type:
9050	<ul>
9051	<li><link to="IVirtualBox::openHardDisk"/></li>
9052	<li><link to="IVirtualBox::openDVDImage"/></li>
9053	<li><link to="IVirtualBox::openFloppyImage"/></li>
9054	</ul>
9055
9056	New hard disk media can be created with the VirtualBox API using the
9057	<link to="IVirtualBox::createHardDisk"/> method.
9058
9059	CD/DVD and floppy images (ISO and RAW files) are usually created outside
9060	VirtualBox, e.g. by storing a copy of the real medium of the corresponding
9061	type in a regular file.
9062
9063	Only for CD/DVDs and floppies, an IMedium instance can also represent a host
9064	drive; in that case the <link to="#id" /> attribute contains the UUID of
9065	one of the drives in <link to="IHost::DVDDrives" /> or <link to="IHost::floppyDrives" />.
9066
9067	<h3>Known media</h3>
9068
9069	When an existing medium is opened for the first time, it is automatically
9070	remembered by the given VirtualBox installation or, in other words, becomes
9071	a <i>known medium</i>. Known media are stored in the media
9072	registry transparently maintained by VirtualBox and stored in settings
9073	files so that this registry is preserved when VirtualBox is not running.
9074
9075	Newly created virtual media are remembered only when the associated
9076	storage unit is actually created.
9077
9078	All known media can be enumerated using
9079	<link to="IVirtualBox::hardDisks"/>,
9080	<link to="IVirtualBox::DVDImages"/> and
9081	<link to="IVirtualBox::floppyImages"/> attributes. Individual media can be
9082	quickly found by UUID using <link to="IVirtualBox::getHardDisk"/>
9083	and similar methods or by location using
9084	<link to="IVirtualBox::findHardDisk"/> and similar methods.
9085
9086	Only known media can be attached to virtual machines.
9087
9088	Removing known media from the media registry is performed when the given
9089	medium is closed using the <link to="#close"/> method or when its
9090	associated storage unit is deleted.
9091
9092	<h3>Accessibility checks</h3>
9093
9094	VirtualBox defers media accessibility checks until the <link to="#refreshState" />
9095	method is called explicitly on a medium. This is done to make the VirtualBox object
9096	ready for serving requests as fast as possible and let the end-user
9097	application decide if it needs to check media accessibility right away or not.
9098
9099	As a result, when VirtualBox starts up (e.g. the VirtualBox
9100	object gets created for the first time), all known media are in the
9101	"Inaccessible" state, but the value of the <link to="#lastAccessError"/>
9102	attribute is an empty string because no actual accessibility check has
9103	been made yet.
9104
9105	After calling <link to="#refreshState" />, a medium is considered
9106	<i>accessible</i> if its storage unit can be read. In that case, the
9107	<link to="#state"/> attribute has a value of "Created". If the storage
9108	unit cannot be read (for example, because it is located on a disconnected
9109	network resource, or was accidentally deleted outside VirtualBox),
9110	the medium is considered <i>inaccessible</i>, which is indicated by the
9111	"Inaccessible" state. The exact reason why the medium is inaccessible can be
9112	obtained by reading the <link to="#lastAccessError"/> attribute.
9113
9114	<h3>Medium types</h3>
9115
9116	There are three types of medium behavior (see <link to="MediumType" />):
9117	"normal", "immutable" and "writethrough", represented by the
9118	<link to="#type"/> attribute. The type of the medium defines how the
9119	medium is attached to a virtual machine and what happens when a
9120	<link to="ISnapshot">snapshot</link> of the virtual machine with the
9121	attached medium is taken. At the moment DVD and floppy media are always
9122	of type "writethrough".
9123
9124	All media can be also divided in two groups: <i>base</i> media and
9125	<i>differencing</i> media. A base medium contains all sectors of the
9126	medium data in its own storage and therefore can be used independently.
9127	In contrast, a differencing mediun is a "delta" to some other medium and
9128	contains only those sectors which differ from that other medium, which is
9129	then called a <i>parent</i>. The differencing medium is said to be
9130	<i>linked to</i> that parent. The parent may be itself a differencing
9131	medium, thus forming a chain of linked media. The last element in that
9132	chain must always be a base medium. Note that several differencing
9133	media may be linked to the same parent medium.
9134
9135	Differencing media can be distinguished from base media by querying the
9136	<link to="#parent"/> attribute: base media do not have parents they would
9137	depend on, so the value of this attribute is always @c null for them.
9138	Using this attribute, it is possible to walk up the medium tree (from the
9139	child medium to its parent). It is also possible to walk down the tree
9140	using the <link to="#children"/> attribute.
9141
9142	Note that the type of all differencing media is "Normal"; all other
9143	values are meaningless for them. Base media may be of any type.
9144
9145	<h3>Creating hard disks</h3>
9146
9147	New base hard disks are created using
9148	<link to="IVirtualBox::createHardDisk"/>. Existing hard disks are
9149	opened using <link to="IVirtualBox::openHardDisk"/>. Differencing hard
9150	disks are usually implicitly created by VirtualBox when needed but may
9151	also be created explicitly using <link to="#createDiffStorage"/>.
9152
9153	After the hard disk is successfully created (including the storage unit)
9154	or opened, it becomes a known hard disk (remembered in the internal media
9155	registry). Known hard disks can be attached to a virtual machine, accessed
9156	through <link to="IVirtualBox::getHardDisk"/> and
9157	<link to="IVirtualBox::findHardDisk"/> methods or enumerated using the
9158	<link to="IVirtualBox::hardDisks"/> array (only for base hard disks).
9159
9160	The following methods, besides <link to="IMedium::close"/>,
9161	automatically remove the hard disk from the media registry:
9162	<ul>
9163	<li><link to="#deleteStorage"/></li>
9164	<li><link to="#mergeTo"/></li>
9165	</ul>
9166
9167	If the storage unit of the hard disk is a regular file in the host's
9168	file system then the rules stated in the description of the
9169	<link to="IMedium::location"/> attribute apply when setting its value. In
9170	addition, a plain file name without any path may be given, in which case
9171	the <link to="ISystemProperties::defaultHardDiskFolder"> default hard disk
9172	folder</link> will be prepended to it.
9173
9174	<h4>Automatic composition of the file name part</h4>
9175
9176	Another extension to the <link to="IMedium::location"/> attribute is that
9177	there is a possibility to cause VirtualBox to compose a unique value for
9178	the file name part of the location using the UUID of the hard disk. This
9179	applies only to hard disks in <link to="MediumState_NotCreated"/> state,
9180	e.g. before the storage unit is created, and works as follows. You set the
9181	value of the <link to="IMedium::location"/> attribute to a location
9182	specification which only contains the path specification but not the file
9183	name part and ends with either a forward slash or a backslash character.
9184	In response, VirtualBox will generate a new UUID for the hard disk and
9185	compose the file name using the following pattern:
9186	<pre>
9187	<path>/{<uuid>}.<ext>
9188	</pre>
9189	where <tt><path></tt> is the supplied path specification,
9190	<tt><uuid></tt> is the newly generated UUID and <tt><ext></tt>
9191	is the default extension for the storage format of this hard disk. After
9192	that, you may call any of the methods that create a new hard disk storage
9193	unit and they will use the generated UUID and file name.
9194
9195	<h3>Attaching Hard Disks</h3>
9196
9197	Hard disks are attached to virtual machines using the
9198	<link to="IMachine::attachDevice"/> method and detached using the
9199	<link to="IMachine::detachDevice"/> method. Depending on their
9200	<link to="#type"/>, hard disks are attached either
9201	<i>directly</i> or <i>indirectly</i>.
9202
9203	When a hard disk is being attached directly, it is associated with the
9204	virtual machine and used for hard disk operations when the machine is
9205	running. When a hard disk is being attached indirectly, a new differencing
9206	hard disk linked to it is implicitly created and this differencing hard
9207	disk is associated with the machine and used for hard disk operations.
9208	This also means that if <link to="IMachine::attachDevice"/> performs
9209	a direct attachment then the same hard disk will be returned in response
9210	to the subsequent <link to="IMachine::getMedium"/> call; however if
9211	an indirect attachment is performed then
9212	<link to="IMachine::getMedium"/> will return the implicitly created
9213	differencing hard disk, not the original one passed to <link
9214	to="IMachine::attachDevice"/>. In detail:
9215
9216	<ul>
9217	<li><b>Normal base</b> hard disks that do not have children (i.e.
9218	differencing hard disks linked to them) and that are not already
9219	attached to virtual machines in snapshots are attached <b>directly</b>.
9220	Otherwise, they are attached <b>indirectly</b> because having
9221	dependent children or being part of the snapshot makes it impossible
9222	to modify hard disk contents without breaking the integrity of the
9223	dependent party. The <link to="#readOnly"/> attribute allows to
9224	quickly determine the kind of the attachment for the given hard
9225	disk. Note that if a normal base hard disk is to be indirectly
9226	attached to a virtual machine with snapshots then a special
9227	procedure called <i>smart attachment</i> is performed (see below).</li>
9228	<li><b>Normal differencing</b> hard disks are like normal base hard disks:
9229	they are attached <b>directly</b> if they do not have children and are
9230	not attached to virtual machines in snapshots, and <b>indirectly</b>
9231	otherwise. Note that the smart attachment procedure is never performed
9232	for differencing hard disks.</li>
9233	<li><b>Immutable</b> hard disks are always attached <b>indirectly</b> because
9234	they are designed to be non-writable. If an immutable hard disk is
9235	attached to a virtual machine with snapshots then a special
9236	procedure called smart attachment is performed (see below).</li>
9237	<li><b>Writethrough</b> hard disks are always attached <b>directly</b>,
9238	also as designed. This also means that writethrough hard disks cannot
9239	have other hard disks linked to them at all.</li>
9240	</ul>
9241
9242	Note that the same hard disk, regardless of its type, may be attached to
9243	more than one virtual machine at a time. In this case, the machine that is
9244	started first gains exclusive access to the hard disk and attempts to
9245	start other machines having this hard disk attached will fail until the
9246	first machine is powered down.
9247
9248	Detaching hard disks is performed in a <i>deferred</i> fashion. This means
9249	that the given hard disk remains associated with the given machine after a
9250	successful <link to="IMachine::detachDevice"/> call until
9251	<link to="IMachine::saveSettings"/> is called to save all changes to
9252	machine settings to disk. This deferring is necessary to guarantee that
9253	the hard disk configuration may be restored at any time by a call to
9254	<link to="IMachine::discardSettings"/> before the settings
9255	are saved (committed).
9256
9257	Note that if <link to="IMachine::discardSettings"/> is called after
9258	indirectly attaching some hard disks to the machine but before a call to
9259	<link to="IMachine::saveSettings"/> is made, it will implicitly delete
9260	all differencing hard disks implicitly created by
9261	<link to="IMachine::attachDevice"/> for these indirect attachments.
9262	Such implicitly created hard disks will also be immediately deleted when
9263	detached explicitly using the <link to="IMachine::detachDevice"/>
9264	call if it is made before <link to="IMachine::saveSettings"/>. This
9265	implicit deletion is safe because newly created differencing hard
9266	disks do not contain any user data.
9267
9268	However, keep in mind that detaching differencing hard disks that were
9269	implicitly created by <link to="IMachine::attachDevice"/>
9270	before the last <link to="IMachine::saveSettings"/> call will
9271	<b>not</b> implicitly delete them as they may already contain some data
9272	(for example, as a result of virtual machine execution). If these hard
9273	disks are no more necessary, the caller can always delete them explicitly
9274	using <link to="#deleteStorage"/> after they are actually de-associated
9275	from this machine by the <link to="IMachine::saveSettings"/> call.
9276
9277	<h3>Smart Attachment</h3>
9278
9279	When normal base or immutable hard disks are indirectly attached to a
9280	virtual machine then some additional steps are performed to make sure the
9281	virtual machine will have the most recent "view" of the hard disk being
9282	attached. These steps include walking through the machine's snapshots
9283	starting from the current one and going through ancestors up to the first
9284	snapshot. Hard disks attached to the virtual machine in all
9285	of the encountered snapshots are checked whether they are descendants of
9286	the given normal base or immutable hard disk. The first found child (which
9287	is the differencing hard disk) will be used instead of the normal base or
9288	immutable hard disk as a parent for creating a new differencing hard disk
9289	that will be actually attached to the machine. And only if no descendants
9290	are found or if the virtual machine does not have any snapshots then the
9291	normal base or immutable hard disk will be used itself as a parent for
9292	this differencing hard disk.
9293
9294	It is easier to explain what smart attachment does using the
9295	following example:
9296	<pre>
9297	BEFORE attaching B.vdi: AFTER attaching B.vdi:
9298
9299	Snapshot 1 (B.vdi) Snapshot 1 (B.vdi)
9300	Snapshot 2 (D1->B.vdi) Snapshot 2 (D1->B.vdi)
9301	Snapshot 3 (D2->D1.vdi) Snapshot 3 (D2->D1.vdi)
9302	Snapshot 4 (none) Snapshot 4 (none)
9303	CurState (none) CurState (D3->D2.vdi)
9304
9305	NOT
9306	...
9307	CurState (D3->B.vdi)
9308	</pre>
9309	The first column is the virtual machine configuration before the base hard
9310	disk <tt>B.vdi</tt> is attached, the second column shows the machine after
9311	this hard disk is attached. Constructs like <tt>D1->B.vdi</tt> and similar
9312	mean that the hard disk that is actually attached to the machine is a
9313	differencing hard disk, <tt>D1.vdi</tt>, which is linked to (based on)
9314	another hard disk, <tt>B.vdi</tt>.
9315
9316	As we can see from the example, the hard disk <tt>B.vdi</tt> was detached
9317	from the machine before taking Snapshot 4. Later, after Snapshot 4 was
9318	taken, the user decides to attach <tt>B.vdi</tt> again. <tt>B.vdi</tt> has
9319	dependent child hard disks (<tt>D1.vdi</tt>, <tt>D2.vdi</tt>), therefore
9320	it cannot be attached directly and needs an indirect attachment (i.e.
9321	implicit creation of a new differencing hard disk). Due to the smart
9322	attachment procedure, the new differencing hard disk
9323	(<tt>D3.vdi</tt>) will be based on <tt>D2.vdi</tt>, not on
9324	<tt>B.vdi</tt> itself, since <tt>D2.vdi</tt> is the most recent view of
9325	<tt>B.vdi</tt> existing for this snapshot branch of the given virtual
9326	machine.
9327
9328	Note that if there is more than one descendant hard disk of the given base
9329	hard disk found in a snapshot, and there is an exact device, channel and
9330	bus match, then this exact match will be used. Otherwise, the youngest
9331	descendant will be picked up.
9332
9333	There is one more important aspect of the smart attachment procedure which
9334	is not related to snapshots at all. Before walking through the snapshots
9335	as described above, the backup copy of the current list of hard disk
9336	attachment is searched for descendants. This backup copy is created when
9337	the hard disk configuration is changed for the first time after the last
9338	<link to="IMachine::saveSettings"/> call and used by
9339	<link to="IMachine::discardSettings"/> to undo the recent hard disk
9340	changes. When such a descendant is found in this backup copy, it will be
9341	simply re-attached back, without creating a new differencing hard disk for
9342	it. This optimization is necessary to make it possible to re-attach the

9644	the state only.
9645
9646	The refresh, if performed, may take a long time (several seconds or even
9647	minutes, depending on the storage unit location and format) because it performs an
9648	accessibility check of the storage unit. This check may cause a significant
9649	delay if the storage unit of the given medium is, for example, a file located
9650	on a network share which is not currently accessible due to connectivity
9651	problems. In that case, the call will not return until a timeout
9652	interval defined by the host OS for this operation expires. For this reason,
9653	it is recommended to never read this attribute on the main UI thread to avoid
9654	making the UI unresponsive.

9704
9705	A read lock is shared: many clients can simultaneously lock the
9706	same medium for reading unless it is already locked for writing (see
9707	<link to="#lockWrite"/>) in which case an error is returned.
9708
9709	When the medium is locked for reading, it cannot be modified
9710	from within VirtualBox. This means that any method that changes
9711	the properties of this medium or contents of the storage unit
9712	will return an error (unless explicitly stated otherwise). That
9713	includes an attempt to start a virtual machine that wants to
9714	write to the the medium.
9715
9716	When the virtual machine is started up, it locks for reading all
9717	media it uses in read-only mode. If some medium cannot be locked
9718	for reading, the startup procedure will fail.
9719	A medium is typically locked for reading while it is used by a running
9720	virtual machine but has a depending differencing image that receives
9721	the actual write operations. This way one base medium can have
9722	multiple child differencing images which can be written to
9723	simultaneously. Read-only media such as DVD and floppy images are
9724	also locked for reading only (so they can be in use by multiple
9725	machines simultaneously).
9726
9727	A medium is also locked for reading when it is the source of a
9728	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9729
9730	The medium locked for reading must be unlocked using the <link
9731	to="#unlockRead"/> method. Calls to <link to="#lockRead"/>
9732	can be nested and must be followed by the same number of paired
9733	<link to="#unlockRead"/> calls.
9734
9735	This method sets the medium state (see <link to="#state"/>) to
9736	"LockedRead" on success. The medium's previous state must be
9737	one of "Created", "Inaccessible" or "LockedRead".
9738
9739	Locking an inaccessible medium is not an error; this method performs
9740	a logical lock that prevents modifications of this medium through
9741	the VirtualBox API, not a physical file-system lock of the underlying

9787	and there may be no read locks while the write lock is held.
9788	As a result, read-locking fails if a write lock is held, and
9789	write-locking fails if either a read or another write lock is held.
9790
9791	When a medium is locked for writing, it cannot be modified
9792	from within VirtualBox, and it is not guaranteed that the values
9793	of its properties are up-to-date. Any method that changes the
9794	properties of this medium or contents of the storage unit will
9795	return an error (unless explicitly stated otherwise).
9796
9797	When a virtual machine is started up, it locks for writing all
9798	media it uses to write data to. If any medium could not be locked
9799	for writing, the startup procedure will fail. If a medium has
9800	differencing images, then while the machine is running, only
9801	the last ("leaf") differencing image is locked for writing,
9802	whereas its parents are locked for reading only.
9803
9804	A medium is also locked for writing when it is the target of a
9805	write operation such as <link to="#cloneTo"/> or <link to="#mergeTo"/>.
9806
9807	The medium locked for writing must be unlocked using the <link

10131	<desc>
10132	Starts merging the contents of this medium and all intermediate
10133	differencing media in the chain to the given target medium.
10134
10135	The target medium must be either a descendant of this medium or
10136	its ancestor (otherwise this method will immediately return a failure).
10137	It follows that there are two logical directions of the merge operation:
10138	from ancestor to descendant (<i>forward merge</i>) and from descendant to
10139	ancestor (<i>backward merge</i>). Let us consider the following medium
10140	chain:
10141
10142	<pre>Base <- Diff_1 <- Diff_2</pre>
10143
10144	Here, calling this method on the <tt>Base</tt> medium object with
10145	<tt>Diff_2</tt> as an argument will be a forward merge; calling it on
10146	<tt>Diff_2</tt> with <tt>Base</tt> as an argument will be a backward
10147	merge. Note that in both cases the contents of the resulting medium
10148	will be the same, the only difference is the medium object that takes
10149	the result of the merge operation. In case of the forward merge in the
10150	above example, the result will be written to <tt>Diff_2</tt>; in case of
10151	the backward merge, the result will be written to <tt>Base</tt>. In
10152	other words, the result of the operation is always stored in the target
10153	medium.
10154
10155	Upon successful operation completion, the storage units of all media in
10156	the chain between this (source) medium and the target medium, including
10157	the source medium itself, will be automatically deleted and the
10158	relevant medium objects (including this medium) will become
10159	uninitialized. This means that any attempt to call any of
10160	their methods or attributes will fail with the
10161	<tt>"Object not ready" (E_ACCESSDENIED)</tt> error. Applied to the above
10162	example, the forward merge of <tt>Base</tt> to <tt>Diff_2</tt> will
10163	delete and uninitialize both <tt>Base</tt> and <tt>Diff_1</tt> media.
10164	Note that <tt>Diff_2</tt> in this case will become a base medium
10165	itself since it will no longer be based on any other medium.
10166
10167	Considering the above, all of the following conditions must be met in
10168	order for the merge operation to succeed:
10169	<ul>
10170	<li>
10171	Neither this (source) medium nor any intermediate
10172	differencing medium in the chain between it and the target
10173	medium is attached to any virtual machine.
10174	</li>
10175	<li>
10176	Neither the source medium nor the target medium is an
10177	<link to="MediumType_Immutable"/> medium.
10178	</li>
10179	<li>
10180	The part of the medium tree from the source medium to the
10181	target medium is a linear chain, i.e. all medium in this
10182	chain have exactly one child which is the next medium in this
10183	chain. The only exception from this rule is the target medium in
10184	the forward merge operation; it is allowed to have any number of
10185	child media because the merge operation will not change its
10186	logical contents (as it is seen by the guest OS or by children).
10187	</li>
10188	<li>
10189	None of the involved media are in
10190	<link to="MediumState_LockedRead"/> or
10191	<link to="MediumState_LockedWrite"/> state.
10192	</li>
10193	</ul>
10194
10195	<note>
10196	This (source) medium and all intermediates will be placed to <link
10197	to="MediumState_Deleting"/> state and the target medium will be
10198	placed to <link to="MediumState_LockedWrite"/> state and for the
10199	duration of this operation.

10217	The target medium must be either in <link to="MediumState_NotCreated"/>

10225
10226	The @a parent argument defines which medium will be the parent

10922	Requests a size and pixel format change.
10923
10924	There are two modes of working with the video buffer of the virtual
10925	machine. The <i>indirect</i> mode implies that the IFramebuffer
10926	implementation allocates a memory buffer for the requested display mode
10927	and provides it to the virtual machine. In <i>direct</i> mode, the
10928	IFramebuffer implementation uses the memory buffer allocated and owned
10929	by the virtual machine. This buffer represents the video memory of the
10930	emulated video adapter (so called <i>guest VRAM</i>). The direct mode is
10931	usually faster because the implementation gets a raw pointer to the
10932	guest VRAM buffer which it can directly use for visualizing the contents
10933	of the virtual display, as opposed to the indirect mode where the
10934	contents of guest VRAM are copied to the memory buffer provided by
10935	the implementation every time a display update occurs.
10936
10937	It is important to note that the direct mode is really fast only when
10938	the implementation uses the given guest VRAM buffer directly, for
10939	example, by blitting it to the window representing the virtual machine's
10940	display, which saves at least one copy operation comparing to the
10941	indirect mode. However, using the guest VRAM buffer directly is not
10942	always possible: the format and the color depth of this buffer may be
10943	not supported by the target window, or it may be unknown (opaque) as in
10944	case of text or non-linear multi-plane VGA video modes. In this case,
10945	the indirect mode (that is always available) should be used as a
10946	fallback: when the guest VRAM contents are copied to the
10947	implementation-provided memory buffer, color and format conversion is
10948	done automatically by the underlying code.
10949
10950	The @a pixelFormat parameter defines whether the direct mode is
10951	available or not. If @a pixelFormat is <link
10952	to="FramebufferPixelFormat_Opaque"/> then direct access to the guest
10953	VRAM buffer is not available -- the @a VRAM, @a bitsPerPixel and
10954	@a bytesPerLine parameters must be ignored and the implementation must use
10955	the indirect mode (where it provides its own buffer in one of the
10956	supported formats). In all other cases, @a pixelFormat together with
10957	@a bitsPerPixel and @a bytesPerLine define the format of the video memory
10958	buffer pointed to by the @a VRAM parameter and the implementation is
10959	free to choose which mode to use. To indicate that this frame buffer uses
10960	the direct mode, the implementation of the <link to="#usesGuestVRAM"/>
10961	attribute must return @c true and <link to="#address"/> must
10962	return exactly the same address that is passed in the @a VRAM parameter
10963	of this method; otherwise it is assumed that the indirect strategy is
10964	chosen.
10965
10966	The @a width and @a height parameters represent the size of the
10967	requested display mode in both modes. In case of indirect mode, the
10968	provided memory buffer should be big enough to store data of the given
10969	display mode. In case of direct mode, it is guaranteed that the given
10970	@a VRAM buffer contains enough space to represent the display mode of the
10971	given size. Note that this frame buffer's <link to="#width"/> and <link
10972	to="#height"/> attributes must return exactly the same values as
10973	passed to this method after the resize is completed (see below).
10974
10975	The @a finished output parameter determines if the implementation has
10976	finished resizing the frame buffer or not. If, for some reason, the
10977	resize cannot be finished immediately during this call, @a finished
10978	must be set to @c false, and the implementation must call
10979	<link to="IDisplay::resizeCompleted"/> after it has returned from
10980	this method as soon as possible. If @a finished is @c false, the
10981	machine will not call any frame buffer methods until
10982	<link to="IDisplay::resizeCompleted"/> is called.
10983
10984	Note that if the direct mode is chosen, the <link to="#bitsPerPixel"/>,
10985	<link to="#bytesPerLine"/> and <link to="#pixelFormat"/> attributes of
10986	this frame buffer must return exactly the same values as specified in the
10987	parameters of this method, after the resize is completed. If the
10988	indirect mode is chosen, these attributes must return values describing
10989	the format of the implementation's own memory buffer <link
10990	to="#address"/> points to. Note also that the <link to="#bitsPerPixel"/>
10991	value must always correlate with <link to="#pixelFormat"/>. Note that
10992	the <link to="#pixelFormat"/> attribute must never return <link
10993	to="FramebufferPixelFormat_Opaque"/> regardless of the selected mode.

12121	The IUSBDeviceFilter interface represents an USB device filter used
12122	to perform actions on a group of USB devices.
12123
12124	This type of filters is used by running virtual machines to
12125	automatically capture selected USB devices once they are physically
12126	attached to the host computer.
12127
12128	A USB device is matched to the given device filter if and only if all
12129	attributes of the device match the corresponding attributes of the
12130	filter (that is, attributes are joined together using the logical AND
12131	operation). On the other hand, all together, filters in the list of
12132	filters carry the semantics of the logical OR operation. So if it is
12133	desirable to create a match like "this vendor id OR this product id",
12134	one needs to create two filters and specify "any match" (see below)
12135	for unused attributes.
12136
12137	All filter attributes used for matching are strings. Each string
12138	is an expression representing a set of values of the corresponding
12139	device attribute, that will match the given filter. Currently, the
12140	following filtering expressions are supported:
12141
12142	<ul>
12143	<li><i>Interval filters</i>. Used to specify valid intervals for
12144	integer device attributes (Vendor ID, Product ID and Revision).
12145	The format of the string is:
12146
12147	<tt>int:((m)\|([m]-[n]))(,(m)\|([m]-[n]))*</tt>
12148
12149	where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
12150	(starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
12151	or decimal (otherwise) form, so that <tt>m < n</tt>. If <tt>m</tt>
12152	is omitted before a dash (<tt>-</tt>), the minimum possible integer
12153	is assumed; if <tt>n</tt> is omitted after a dash, the maximum
12154	possible integer is assumed.
12155	</li>
12156	<li><i>Boolean filters</i>. Used to specify acceptable values for
12157	boolean device attributes. The format of the string is:
12158
12159	<tt>true\|false\|yes\|no\|0\|1</tt>
12160
12161	</li>
12162	<li><i>Exact match</i>. Used to specify a single value for the given
12163	device attribute. Any string that doesn't start with <tt>int:</tt>
12164	represents the exact match. String device attributes are compared to
12165	this string including case of symbols. Integer attributes are first
12166	converted to a string (see individual filter attributes) and then
12167	compared ignoring case.
12168
12169	</li>
12170	<li><i>Any match</i>. Any value of the corresponding device attribute
12171	will match the given filter. An empty or @c null string is
12172	used to construct this type of filtering expressions.
12173
12174	</li>
12175	</ul>
12176
12177	<note>
12178	On the Windows host platform, interval filters are not currently
12179	available. Also all string filter attributes
12180	(<link to="#manufacturer"/>, <link to="#product"/>,
12181	<link to="#serialNumber"/>) are ignored, so they behave as
12182	<i>any match</i> no matter what string expression is specified.

12291	of the USB device physically attached to the host computer regarding
12292	its state on the host computer and availability to guest computers
12293	(all currently running virtual machines).
12294
12295	Once a supported USB device is attached to the host, global USB
12296	filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
12297	either ignore the device, or put it to USBDeviceState_Held state, or do
12298	nothing. Unless the device is ignored by global filters, filters of all
12299	currently running guests (<link to="IUSBController::deviceFilters"/>) are
12300	activated that can put it to USBDeviceState_Captured state.
12301
12302	If the device was ignored by global filters, or didn't match
12303	any filters at all (including guest ones), it is handled by the host
12304	in a normal way. In this case, the device state is determined by
12305	the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
12306	or USBDeviceState_Available, depending on the current device usage.
12307
12308	Besides auto-capturing based on filters, the device can be manually
12309	captured by guests (<link to="IConsole::attachUSBDevice"/>) if its
12310	state is USBDeviceState_Busy, USBDeviceState_Available or
12311	USBDeviceState_Held.
12312
12313	<note>
12314	Due to differences in USB stack implementations in Linux and Win32,
12315	states USBDeviceState_Busy and USBDeviceState_vailable are applicable
12316	only to the Linux version of the product. This also means that (<link

12607	<desc>
12608	The ISharedFolder interface represents a folder in the host computer's
12609	file system accessible from the guest OS running inside a virtual
12610	machine using an associated logical name.
12611
12612	There are three types of shared folders:
12613	<ul>
12614	<li><i>Global</i> (<link to="IVirtualBox::sharedFolders"/>), shared
12615	folders available to all virtual machines.</li>
12616	<li><i>Permanent</i> (<link to="IMachine::sharedFolders"/>),
12617	VM-specific shared folders available to the given virtual machine at
12618	startup.</li>
12619	<li><i>Transient</i> (<link to="IConsole::sharedFolders"/>),
12620	VM-specific shared folders created in the session context (for
12621	example, when the virtual machine is running) and automatically
12622	discarded when the session is closed (the VM is powered off).</li>
12623	</ul>
12624
12625	Logical names of shared folders must be unique within the given scope
12626	(global, permanent or transient). However, they do not need to be unique
12627	across scopes. In this case, the definition of the shared folder in a
12628	more specific scope takes precedence over definitions in all other
12629	scopes. The order of precedence is (more specific to more general):
12630	<ol>
12631	<li>Transient definitions</li>
12632	<li>Permanent definitions</li>
12633	<li>Global definitions</li>
12634	</ol>
12635
12636	For example, if MyMachine has a shared folder named
12637	<tt>C_DRIVE</tt> (that points to <tt>C:\\</tt>), then creating a
12638	transient shared folder named <tt>C_DRIVE</tt> (that points
12639	to <tt>C:\\\\WINDOWS</tt>) will change the definition
12640	of <tt>C_DRIVE</tt> in the guest OS so
12641	that <tt>\\\\VBOXSVR\\C_DRIVE</tt> will give access
12642	to <tt>C:\\WINDOWS</tt> instead of <tt>C:\\</tt> on the host
12643	PC. Removing the transient shared folder <tt>C_DRIVE</tt> will restore
12644	the previous (permanent) definition of <tt>C_DRIVE</tt> that points
12645	to <tt>C:\\</tt> if it still exists.
12646
12647	Note that permanent and transient shared folders of different machines
12648	are in different name spaces, so they don't overlap and don't need to
12649	have unique logical names.
12650
12651	<note>
12652	Global shared folders are not implemented in the current version of the
12653	product.

13070	<desc>
13071	The ISession interface represents a serialization primitive for virtual
13072	machines.
13073
13074	With VirtualBox, every time one wishes to manipulate a virtual machine
13075	(e.g. change its settings or start execution), a session object is
13076	required. Such an object must be passed to one of the session methods
13077	that open the given session, which then initiates the machine manipulation.
13078
13079	A session serves several purposes: it identifies to the inter-process VirtualBox
13080	code which process is currently working with the virtual machine, and it ensures
13081	that there are no incompatible requests from several processes for the
13082	same virtual machine. Session objects can therefore be thought of as mutex
13083	semaphores that lock virtual machines to prevent conflicting accesses from
13084	several processes.
13085
13086	How sessions objects are used depends on whether you use the Main API
13087	via COM or via the webservice:
13088
13089	<ul>
13090	<li>When using the COM API directly, an object of the Session class from the
13091	VirtualBox type library needs to be created. In regular COM C++ client code,
13092	this can be done by calling <tt>createLocalObject()</tt>, a standard COM API.
13093	This object will then act as a local session object in further calls to open
13094	a session.
13095	</li>
13096
13097	<li>In the webservice, the session manager (IWebsessionManager) instead creates
13098	one session object automatically when <link to="IWebsessionManager::logon" />
13099	is called. A managed object reference to that session object can be retrieved by
13100	calling <link to="IWebsessionManager::getSessionObject" />. This session object
13101	reference can then be used to open sessions.
13102	</li>
13103	</ul>
13104
13105	Sessions are mainly used in two variations:
13106
13107	<ul>
13108	<li>
13109	To start a virtual machine in a separate process, one would call
13110	<link to="IVirtualBox::openRemoteSession"/>, which requires a session
13111	object as its first parameter. This session then identifies the caller
13112	and lets him control the started machine (for example, pause machine
13113	execution or power it down) as well as be notified about machine
13114	execution state changes.
13115	</li>
13116
13117	<li>To alter machine settings, or to start machine execution within the
13118	current process, one needs to open a direct session for the machine first by
13119	calling <link to="IVirtualBox::openSession"/>. While a direct session
13120	is open within one process, no any other process may open another direct
13121	session for the same machine. This prevents the machine from being changed
13122	by other processes while it is running or while the machine is being configured.
13123	</li>
13124	</ul>
13125
13126	One also can attach to an existing direct session already opened by
13127	another process (for example, in order to send a control request to the
13128	virtual machine such as the pause or the reset request). This is done by
13129	calling <link to="IVirtualBox::openExistingSession"/>.
13130
13131	<note>
13132	Unless you are trying to write a new VirtualBox front-end that
13133	performs direct machine execution (like the VirtualBox or VBoxSDL
13134	front-ends), don't call <link to="IConsole::powerUp"/> in a direct
13135	session opened by <link to="IVirtualBox::openSession"/> and use this
13136	session only to change virtual machine settings. If you simply want to
13137	start virtual machine execution using one of the existing front-ends
13138	(for example the VirtualBox GUI or headless server), simply use
13139	<link to="IVirtualBox::openRemoteSession"/>; these front-ends
13140	will power up the machine automatically for you.

13167
13168	It is recommended that every time an "open session" method (such as
13169	<link to="IVirtualBox::openRemoteSession" /> or
13170	<link to="IVirtualBox::openSession" />) has been called to
13171	manipulate a virtual machine, the caller invoke
13172	ISession::close() when it's done doing so. Since sessions are
13173	serialization primitives much like ordinary mutexes, they are
13174	best used the same way: for each "open" call, there should be
13175	a matching "close" call, even when errors occur.
13176
13177	Otherwise, if a direct session for a machine opened with
13178	<link to="IVirtualBox::openSession"/> is not explicitly closed
13179	when the application terminates, the state of the machine will
13180	be set to <link to="MachineState_Aborted" /> on the server.
13181
13182	Generally, it is recommended to close all open sessions explicitly
13183	before terminating the application (regardless of the reason for
13184	the termination).
13185
13186	<note>
13187	Do not expect the session state (<link to="ISession::state" />
13188	to return to "Closed" immediately after you invoke
13189	ISession::close(), particularly if you have started a remote
13190	session to execute the VM in a new process. The session state will
13191	automatically return to "Closed" once the VM is no longer executing,
13192	which can of course take a very long time.

13277	As opposed to physical hardware, VirtualBox has a very generic concept

13280	There are four types of such virtual storage controllers: IDE, SCSI, SATA
13281	and Floppy (see <link to="#bus" />). Depending on which of these four is

13283	<link to="#controllerType" />.

13564	The IPerformanceCollector interface represents a service that collects and
13565	stores performance metrics data.
13566
13567	Performance metrics are associated with objects of interfaces like IHost and
13568	IMachine. Each object has a distinct set of performance metrics.
13569	The set can be obtained with <link to="IPerformanceCollector::getMetrics"/>.
13570
13571	Metric data is collected at the specified intervals and is retained
13572	internally. The interval and the number of retained samples can be set
13573	with <link to="IPerformanceCollector::setupMetrics" />.
13574
13575	Metrics are organized hierarchically, with each level separated by a
13576	slash (/) character. Generally, the scheme for metric names is like this:
13577
13578	<tt>Category/Metric[/SubMetric][:aggregation]</tt>
13579
13580	"Category/Metric" together form the base metric name. A base metric is the
13581	smallest unit for which a sampling interval and the number of retained
13582	samples can be set. Only base metrics can be enabled and disabled. All
13583	sub-metrics are collected when their base metric is collected.
13584	Collected values for any set of sub-metrics can be queried with
13585	<link to="IPerformanceCollector::queryMetricsData" />.
13586
13587	For example "CPU/Load/User:avg"
13588	metric name stands for the "CPU" category, "Load" metric, "User" submetric,
13589	"average" aggregate. An aggregate function is computed over all retained
13590	data. Valid aggregate functions are:
13591
13592	<ul>
13593	<li>avg -- average</li>
13594	<li>min -- minimum</li>
13595	<li>max -- maximum</li>
13596	</ul>
13597
13598	When setting up
13599	metric parameters, querying metric data, enabling or disabling metrics
13600	wildcards can be used in metric names to specify a subset of metrics. For
13601	example, to select all CPU-related metrics use <tt>CPU/*</tt>, all
13602	averages can be queried using <tt>*:avg</tt> and so on. To query metric
13603	values without aggregates <tt>*:</tt> can be used.
13604
13605	The valid names for base metrics are:
13606
13607	<ul>
13608	<li>CPU/Load</li>
13609	<li>CPU/MHz</li>
13610	<li>RAM/Usage</li>
13611	</ul>
13612
13613	The general sequence for collecting and retrieving the metrics is:
13614	<ul>
13615	<li>
13616	Obtain an instance of IPerformanceCollector with
13617	<link to="IVirtualBox::performanceCollector" />
13618	</li>
13619	<li>
13620	Allocate and populate an array with references to objects the metrics
13621	will be collected for. Use references to IHost and IMachine objects.
13622	</li>
13623	<li>
13624	Allocate and populate an array with base metric names the data will be
13625	collected for.
13626	</li>
13627	<li>
13628	Call <link to="IPerformanceCollector::setupMetrics" />. From now on the
13629	metric data will be collected and stored.
13630	</li>
13631	<li>
13632	Wait for the data to get collected.
13633	</li>
13634	<li>
13635	Allocate and populate an array with references to objects the metric
13636	values will be queried for. You can re-use the object array used for
13637	setting base metrics.
13638	</li>
13639	<li>
13640	Allocate and populate an array with metric names the data will be
13641	collected for. Note that metric names differ from base metric names.
13642	</li>
13643	<li>
13644	Call <link to="IPerformanceCollector::queryMetricsData" />. The data that
13645	have been collected so far are returned. Note that the values are still
13646	retained internally and data collection continues.
