     365    <desc>
     366      The IVirtualBoxErrorInfo interface represents extended error information
     367      that can be set by components after unsuccessful method invocation and
     368      returned to the client in addition to the result code.
     369
     370      In MS COM, this interface extends the IErrorInfo interface,
     371      in XPCOM, it extends the nsIException interface. In both cases,
     372      it provides a set of common attributes to retrieve error
     373      information.
     374
     375      Sometimes invocation of some component's method may involve
     376      methods of other components that may also fail (independently of
     377      this method's failure), or a series of non-fatal errors may
     378      precede a fatal error that causes method failure. In cases like
     379      that, it may be desirable to preserve information about all errors
     380      happened during method invocation and deliver it to the
     381      caller. The <link to="#next"/> attribute is intended specifically
     382      for this purpose and allows to represent a chain of errors through
     383      a single IVirtualBoxErrorInfo instance set after method
     384      invocation. Note that errors are stored to a chain in the reverse
     385      order, i.e. the initial error object you query right after method
     386      invocation is the last error set by the callee, the object it
     387      points to in the @a next attribute is the previous error and so
     388      on, up to the first error (which is the last in the chain).

     391    <attribute name="resultCode" type="result" readonly="yes">
     392      <desc>
     393        Result code of the error.
     394        Usually, it will be the same as the result code returned
     395        by the method that provided this error information, but not
     396        always. For example, on Win32, CoCreateInstance() will most
     397        likely return E_NOINTERFACE upon unsuccessful component
     398        instantiation attempt, but not the value the component factory
     399        returned.
     400        <note>
     401          In MS COM, there is no equivalent.
     402          In XPCOM, it is the same as nsIException::result.

    363             The IVirtualBoxErrorInfo interface represents extended error information
    364             that can be set by components after unsuccessful method invocation and
    365             returned to the client in addition to the result code.
    366 
    367             In MS COM, this interface extends the IErrorInfo interface,
    368             in XPCOM, it extends the nsIException interface. In both cases,
    369             it provides a set of common attributes to retrieve error
    370             information.
    371 
    372             Sometimes invocation of some component's method may involve
    373             methods of other components that may also fail (independently of
    374             this method's failure), or a series of non-fatal errors may
    375             precede a fatal error that causes method failure. In cases like
    376             that, it may be desirable to preserve information about all errors
    377             happened during method invocation and deliver it to the

    380             a single IVirtualBoxErrorInfo instance set after method
    381             invocation. Note that errors are stored to a chain in the reverse

    383             invocation is the last error set by the callee, the object it
    384             points to in the @a next attribute is the previous error and so
    385             on, up to the first error (which is the last in the chain).

    743                 Creates a new virtual machine.
    744 
    745                 Every machine has a <i>settings file</i> that is used to store
    746                 the machine configuration. This file is stored in the directory
    747                 called <i>machine settings subfolder</i>. Both the subfolder
    748                 and the settings file have the same name that corresponds to the
    749                 name of the virtual machine. You can specify where
    750                 to create the machine settings subfolder using the @a
    751                 baseFolder argument. The base folder can be absolute (full path)
    752                 or relative to the <link to="IVirtualBox::homeFolder">
    753                 VirtualBox home directory</link>.
    754 
    755                 If a null or empty string is given as the base folder (which is
    756                 recommended), the <link to="ISystemProperties::defaultMachineFolder">
    757                 default machine settings folder</link> will be used as the base
    758                 folder to create the machine settings subfolder and file. In

    760                 <pre>
    761     &lt;base_folder&gt;/&lt;machine_name&gt;/&lt;machine_name&gt;.xml</pre>
    762 
    763                 Note that the configuration of the newly created machine is not
    764                 saved to disk (and therefore no settings subfolder and file are
    765                 created) until <link to="IMachine::saveSettings()"/> is called.
    766 
    767                 You should also specify a valid name for the machine.
    768                 See the <link to="IMachine::name"/> property

     747
     748        Every machine has a <i>settings file</i> that is used to store
     749        the machine configuration. This file is stored in the directory
     750        called <i>machine settings subfolder</i>. Both the subfolder
     751        and the settings file have the same name that corresponds to the
     752        name of the virtual machine. You can specify where
     753        to create the machine settings subfolder using the @a
     754        baseFolder argument. The base folder can be absolute (full path)
     755        or relative to the <link to="IVirtualBox::homeFolder">
     756          VirtualBox home directory</link>.
     757
     758        If a null or empty string is given as the base folder (which is
     759        recommended), the <link to="ISystemProperties::defaultMachineFolder">
     760          default machine settings folder</link> will be used as the base
     761        folder to create the machine settings subfolder and file. In
     762        any case, the full path to the settings file will look like:
     763        <pre>
     764          &lt;base_folder&gt;/&lt;machine_name&gt;/&lt;machine_name&gt;.xml</pre>
     765
     766        Note that the configuration of the newly created machine is not
     767        saved to disk (and therefore no settings subfolder and file are
     768        created) until <link to="IMachine::saveSettings()"/> is called.
     769
     770        You should also specify a valid name for the machine.
     771        See the <link to="IMachine::name"/> property
     772        description for more details about the machine name.
     773
     774        The created machine remains
     775        unregistered until you call <link to="#registerMachine()"/>.
     776
     777        <note>

    1916                 inaccessibility.
    1917 
    1918                 When the machine is inaccessible, only the following properties
    1919                 can be used on it:
    1920                 <ul>
    1921                     <li><link to="#parent"/></li>
    1922                     <li><link to="#id"/></li>
    1923                     <li><link to="#settingsFilePath"/></li>
    1924                     <li><link to="#accessible"/></li>
    1925                     <li><link to="#accessError"/></li>
    1926                 </ul>
    1927 
    1928                 An attempt to access any other property or method will return
    1929                 an error.
    1930 
    1931                 The only possible action you can perform on an inaccessible
    1932                 machine is to unregister it using the
    1933                 <link to="IVirtualBox::unregisterMachine"/> call (or, to check
    1934                 for the accessibility state once more by querying this
    1935                 property).
    1936 
    1937                 <note>
    1938                     In the current implementation, once this property returns
    1939                     <tt>true</tt>, the machine will never become inaccessible
    1940                     later, even if its settings file cannot be successfully
    1941                     read/written any more (at least, until the VirtualBox
    1942                     server is restarted). This limitation may be removed in
    1943                     future releases.

    1963 
    1964                 Besides being used for human-readable identification purposes
    1965                 everywhere in VirtualBox, the virtual machine name is also used
    1966                 as a name of the machine's settings file and as a name of the
    1967                 subdirectory this settings file resides in. Thus, every time you
    1968                 change the value of this property, the settings file will be
    1969                 renamed once you call <link to="#saveSettings()"/> to confirm the
    1970                 change. The containing subdirectory will be also renamed, but
    1971                 only if it has exactly the same name as the settings file
    1972                 itself prior to changing this property (for backward compatibility
    1973                 with previous API releases). The above implies the following
    1974                 limitations:
    1975                 <ul>
    1976                 <li>The machine name cannot be empty.</li>
    1977                 <li>The machine name can contain only characters that are valid
    1978                     file name characters according to the rules of the file
    1979                     system used to store VirtualBox configuration.</li>
    1980                 <li>You cannot have two or more machines with the same name
    1981                     if they use the same subdirectory for storing the machine
    1982                     settings files.</li>
    1983                 <li>You cannot change the name of the machine if it is running,
    1984                     or if any file in the directory containing the settings file
    1985                     is being used by another running machine or by any other
    1986                     process in the host operating system at a time when
    1987                     <link to="#saveSettings()"/> is called.
    1988                 </li>
    1989                 </ul>
    1990                 If any of the above limitations are hit, <link to="#saveSettings()"/>
    1991                 will return an appropriate error message explaining the exact
    1992                 reason and the changes you made to this machine will not be

    1995                     For "legacy" machines created using the
    1996                     <link to="IVirtualBox::createLegacyMachine()"/> call,
    1997                     the above naming limitations do not apply because the
    1998                     machine name does not affect the settings file name.
    1999                     The settings file name remains the same as it was specified
    2000                     during machine creation and never changes.

    2685 
    2686                     For pointers without alpha channel the XOR mask pixels are 32 bit values: (lsb)BGR0(msb).

    2691 
    2692                     The AND mask is 1 bpp bitmap with byte aligned scanlines. Size of AND mask,
    2693                     therefore, is <tt>cbAnd = (width + 7) / 8 * height</tt>. The padding bits at the

    2698                     Bytes in the gap between the AND and the XOR mask are undefined.
    2699                     XOR mask scanlines have no gap between them and size of XOR mask is:

    2784                 Notification when an error happens during the virtual
    2785                 machine execution.
    2786 
    2787                 There are three kinds of runtime errors:
    2788                 <ul>
    2789                     <li><i>fatal</i></li>
    2790                     <li><i>non-fatal with retry</i></li>
    2791                     <li><i>non-fatal warnings</i></li>
    2792                 </ul>
    2793 
    2794                 <b>Fatal</b> errors are indicated by the @a fatal parameter set
    2795                 to <tt>true</tt>. In case of fatal errors, the virtual machine
    2796                 execution is always paused before calling this notification, and
    2797                 the notification handler is supposed either to immediately save
    2798                 the virtual machine state using <link to="IConsole::saveState()"/>
    2799                 or power it off using <link to="IConsole::powerDown()"/>.
    2800                 Resuming the execution can lead to unpredictable results.
    2801 
    2802                 <b>Non-fatal</b> errors and warnings are indicated by the
    2803                 @a fatal parameter set to <tt>false</tt>. If the virtual machine
    2804                 is in the Paused state by the time the error notification is
    2805                 received, it means that the user can <i>try to resume</i> the machine
    2806                 execution after attempting to solve the probem that caused the
    2807                 error. In this case, the notification handler is supposed
    2808                 to show an appropriate message to the user (depending on the
    2809                 value of the @a id parameter) that offers several actions such
    2810                 as <i>Retry</i>, <i>Save</i> or <i>Power Off</i>. If the user
    2811                 wants to retry, the notification handler should continue
    2812                 the machine execution using the <link to="IConsole::resume()"/>
    2813                 call. If the machine execution is not Paused during this
    2814                 notification, then it means this notification is a <i>warning</i>
    2815                 (for example, about a fatal condition that can happen very soon);
    2816                 no immediate action is required from the user, the machine
    2817                 continues its normal execution.
    2818 
    2819                 Note that in either case the notification handler
    2820                 <b>must not</b> perform any action directly on a thread
    2821                 where this notification is called. Everything it is allowed to
    2822                 do is to post a message to another thread that will then talk
    2823                 to the user and take the corresponding action.
    2824 
    2825                 Currently, the following error identificators are known:
    2826                 <ul>
    2827                 <li><tt>"HostMemoryLow"</tt></li>
    2828                 <li><tt>"HostAudioNotResponding"</tt></li>

    3334             <desc>
    3335 
    3336                 Starts discarding the specified snapshot. The execution state
    3337                 and settings of the associated machine stored in the snapshot
    3338                 will be deleted. The contents of all differencing hard disks of
    3339                 this snapshot will be merged with the contents of their
    3340                 dependent child hard disks to keep the, disks valid (in other
    3341                 words, all changes represented by hard disks being discarded
    3342                 will be propagated to their child hard disks). After that, this
    3343                 snapshot's differencing hard disks will be deleted. The parent
    3344                 of this snapshot will become a new parent for all its child
    3345                 snapshots.
    3346 
    3347                 If the discarded snapshot is the current one, its parent
    3348                 snapshot will become a new current snapshot. The current machine
    3349                 state is not directly affected in this case, except that
    3350                 currently attached differencing hard disks based on hard disks
    3351                 of the discarded snapshot will be also merged as described
    3352                 above.
    3353 
    3354                 If the discarded snapshot is the first one (the root snapshot)
    3355                 and it has exactly one child snapshot, this child snapshot will
    3356                 become the first snapshot after discarding. If there are no
    3357                 children at all (i.e. the first snapshot is the only snapshot of
    3358                 the machine), both the current and the first snapshot of the
    3359                 machine will be set to null. In all other cases, the first
    3360                 snapshot cannot be discarded.
    3361 
    3362                 You cannot discard the snapshot if it stores <link
    3363                 to="HardDiskType::NormalHardDisk">normal</link>
    3364                 (non-differencing) hard disks that have differencing hard disks
    3365                 based on them. Snapshots of such kind can be discarded only when
    3366                 every normal hard disk has either no children at all or exactly
    3367                 one child. In the former case, the normal hard disk simply
    3368                 becomes unused (i.e. not attached to any VM). In the latter
    3369                 case, it receives all the changes strored in the child hard
    3370                 disk, and then it replaces the child hard disk in the
    3371                 configuration of the corresponding snapshot or machine.
    3372 
    3373                 Also, you cannot discard the snapshot if it stores hard disks
    3374                 (of any type) having differencing child hard disks that belong
    3375                 to other machines. Such snapshots can be only discarded after
    3376                 you discard all snapshots of other machines containing "foreign"
    3377                 child disks, or detach these "foreign" child disks from machines
    3378                 they are attached to.
    3379 
    3380                 One particular example of the snapshot storing normal hard disks
    3381                 is the first snapshot of a virtual machine that had normal hard
    3382                 disks attached when taking the snapshot. Be careful when
    3383                 discarding such snapshots because this implicitly commits
    3384                 changes (made since the snapshot being discarded has been taken)
    3385                 to normal hard disks (as described above), which may be not what
    3386                 you want.
    3387 
    3388                 The virtual machine is put to the <link
    3389                 to="MachineState::Discarding">Discarding</link> state until the
    3390                 discard operation is completed.
    3391

    3396                     Child hard disks of all normal hard disks of the
    3397                     discarded snapshot must be <link to="IHardDisk::accessible">
    3398                     accessible</link> for this operation to succeed.
    3399                     In particular, this means that all virtual machines,
    3400                     whose hard disks are directly or indirectly based on
    3401                     the hard disks of discarded snapshot, must be powered off.

    3403                 <note>
    3404                     Merging hard disk contents can be very time and disk space
    3405                     consuming, if these disks are big in size and have many
    3406                     children. However, if the snapshot being discarded is the last
    3407                     (head) snapshot on the branch, the operation will be rather
    3408                     quick.

    3426                 This operation is similar to <link to="#discardSnapshot()"/> but
    3427                 affects the current machine state. This means that the state stored
    3428                 in the current snapshot will become a new current state, and
    3429                 all current settings of the machine and changes stored in
    3430                 differencing hard disks will be lost.
    3431

    3433                 differencing hard disks are created for all normal hard disks

    3435 
    3436                 If the current snapshot of the machine is an online snapshot,
    3437                 the machine will go to the <link to="MachineState::Saved">

    3458                 This method is equivalent to doing <link

    3460                 to="IMachine::currentSnapshot">currentSnapshot</link>.<link

    3462                 to="#discardCurrentState()"/>.
    3463 
    3464                 As a result, the machine will be fully restored from the
    3465                 snapshot preceeding the current snapshot, while both the current
    3466                 snapshot and the current machine state will be discarded.
    3467 
    3468                 If the current snapshot is the first snapshot of the machine
    3469                 (i.e. it has the only snapshot), the current machine state will
    3470                 be discarded <b>before</b> discarding the snapshot. In other
    3471                 words, the machine will be restored from its last snapshot,
    3472                 before discarding it. This differs from performing a single
    3473                 <link to="#discardSnapshot()"/> call (note that no <link
    3474                 to="#discardCurrentState()"/> will be possible after it) to the

     1950          server is restarted). This limitation may be removed in

     1970        Name of the virtual machine.
     1971
     1972        Besides being used for human-readable identification purposes
     1973        everywhere in VirtualBox, the virtual machine name is also used
     1974        as a name of the machine's settings file and as a name of the
     1975        subdirectory this settings file resides in. Thus, every time you
     1976        change the value of this property, the settings file will be
     1977        renamed once you call <link to="#saveSettings()"/> to confirm the
     1978        change. The containing subdirectory will be also renamed, but
     1979        only if it has exactly the same name as the settings file
     1980        itself prior to changing this property (for backward compatibility
     1981        with previous API releases). The above implies the following
     1982        limitations:
     1983        <ul>
     1984          <li>The machine name cannot be empty.</li>
     1985          <li>The machine name can contain only characters that are valid
     1986            file name characters according to the rules of the file
     1987            system used to store VirtualBox configuration.</li>
     1988          <li>You cannot have two or more machines with the same name
     1989            if they use the same subdirectory for storing the machine
     1990            settings files.</li>
     1991          <li>You cannot change the name of the machine if it is running,
     1992            or if any file in the directory containing the settings file
     1993            is being used by another running machine or by any other
     1994            process in the host operating system at a time when
     1995            <link to="#saveSettings()"/> is called.
     1996          </li>
     1997        </ul>
     1998        If any of the above limitations are hit, <link to="#saveSettings()"/>
     1999        will return an appropriate error message explaining the exact
     2000        reason and the changes you made to this machine will not be
     2001        saved.
     2002        <note>
     2003          For "legacy" machines created using the
     2004          <link to="IVirtualBox::createLegacyMachine()"/> call,
     2005          the above naming limitations do not apply because the
     2006          machine name does not affect the settings file name.
     2007          The settings file name remains the same as it was specified
     2008          during machine creation and never changes.

     2701
     2702          The AND mask is 1 bpp bitmap with byte aligned scanlines. Size of AND mask,

     2704          end of any scanline are undefined.
     2705
     2706          The XOR mask follows the AND mask on the next 4 bytes aligned offset:
     2707          <tt>uint8_t *pXor = pAnd + (cbAnd + 3) &amp; ~3</tt>
     2708          Bytes in the gap between the AND and the XOR mask are undefined.
     2709          XOR mask scanlines have no gap between them and size of XOR mask is:
     2710          <tt>cXor = width * 4 * height</tt>.

     2793      <desc>
     2794        Notification when an error happens during the virtual
     2795        machine execution.
     2796
     2797        There are three kinds of runtime errors:
     2798        <ul>
     2799          <li><i>fatal</i></li>
     2800          <li><i>non-fatal with retry</i></li>
     2801          <li><i>non-fatal warnings</i></li>
     2802        </ul>
     2803
     2804        <b>Fatal</b> errors are indicated by the @a fatal parameter set
     2805        to <tt>true</tt>. In case of fatal errors, the virtual machine
     2806        execution is always paused before calling this notification, and
     2807        the notification handler is supposed either to immediately save
     2808        the virtual machine state using <link to="IConsole::saveState()"/>
     2809        or power it off using <link to="IConsole::powerDown()"/>.
     2810        Resuming the execution can lead to unpredictable results.
     2811
     2812        <b>Non-fatal</b> errors and warnings are indicated by the
     2813        @a fatal parameter set to <tt>false</tt>. If the virtual machine
     2814        is in the Paused state by the time the error notification is
     2815        received, it means that the user can <i>try to resume</i> the machine
     2816        execution after attempting to solve the probem that caused the
     2817        error. In this case, the notification handler is supposed
     2818        to show an appropriate message to the user (depending on the
     2819        value of the @a id parameter) that offers several actions such
     2820        as <i>Retry</i>, <i>Save</i> or <i>Power Off</i>. If the user
     2821        wants to retry, the notification handler should continue
     2822        the machine execution using the <link to="IConsole::resume()"/>
     2823        call. If the machine execution is not Paused during this
     2824        notification, then it means this notification is a <i>warning</i>
     2825        (for example, about a fatal condition that can happen very soon);
     2826        no immediate action is required from the user, the machine
     2827        continues its normal execution.
     2828
     2829        Note that in either case the notification handler
     2830        <b>must not</b> perform any action directly on a thread
     2831        where this notification is called. Everything it is allowed to
     2832        do is to post a message to another thread that will then talk
     2833        to the user and take the corresponding action.
     2834
     2835        Currently, the following error identificators are known:
     2836        <ul>
     2837          <li><tt>"HostMemoryLow"</tt></li>
     2838          <li><tt>"HostAudioNotResponding"</tt></li>
     2839          <li><tt>"VDIStorageFull"</tt></li>
     2840        </ul>
     2841
     2842        <note>
     2843          This notification is not designed to be implemented by
     2844          more than one callback at a time. If you have multiple
     2845          IConsoleCallback instances registered on the given
     2846          IConsole object, make sure you simply do nothing but
     2847          return @c S_OK from all but one of them that does actual
     2848          user notification and performs necessary actions.

     2897        foreground on the desktop of the host PC.
     2898
     2899        This notification should cause the VM console process to
     2900        perform the requested action as described above. If it is
     2901        impossible to do it at a time of this notification, this
     2902        method should return a failure.
     2903
     2904        Note that many modern window managers on many platforms
     2905        implement some sort of focus stealing prevention logic, so
     2906        that it may be impossible to activate a window without the
     2907        help of the currently active application (which is supposedly
     2908        an initiator of this notification). In this case, this method
     2909        must return a non-zero identifier that represents the
     2910        top-level window of the VM console process. The caller, if it
     2911        represents a currently active process, is responsible to use
     2912        this identifier (in a platform-dependent manner) to perform
     2913        actual window activation.
     2914
     2915        This method must set @a winId to zero if it has performed all
     2916        actions necessary to complete the request and the console
     2917        window is now active and in foreground, to indicate that no
     2918        further action is required on the caller's side.

     3349        Starts discarding the specified snapshot. The execution state
     3350        and settings of the associated machine stored in the snapshot
     3351        will be deleted. The contents of all differencing hard disks of
     3352        this snapshot will be merged with the contents of their
     3353        dependent child hard disks to keep the, disks valid (in other
     3354        words, all changes represented by hard disks being discarded
     3355        will be propagated to their child hard disks). After that, this
     3356        snapshot's differencing hard disks will be deleted. The parent
     3357        of this snapshot will become a new parent for all its child
     3358        snapshots.
     3359
     3360        If the discarded snapshot is the current one, its parent
     3361        snapshot will become a new current snapshot. The current machine
     3362        state is not directly affected in this case, except that
     3363        currently attached differencing hard disks based on hard disks
     3364        of the discarded snapshot will be also merged as described
     3365        above.
     3366
     3367        If the discarded snapshot is the first one (the root snapshot)
     3368        and it has exactly one child snapshot, this child snapshot will
     3369        become the first snapshot after discarding. If there are no
     3370        children at all (i.e. the first snapshot is the only snapshot of
     3371        the machine), both the current and the first snapshot of the
     3372        machine will be set to null. In all other cases, the first
     3373        snapshot cannot be discarded.
     3374
     3375        You cannot discard the snapshot if it
     3376        stores <link to="HardDiskType::NormalHardDisk">normal</link>
     3377        (non-differencing) hard disks that have differencing hard disks based
     3378        on them. Snapshots of such kind can be discarded only when every
     3379        normal hard disk has either no children at all or exactly one
     3380        child. In the former case, the normal hard disk simply becomes unused
     3381        (i.e. not attached to any VM). In the latter case, it receives all the
     3382        changes strored in the child hard disk, and then it replaces the child
     3383        hard disk in the configuration of the corresponding snapshot or
     3384        machine.
     3385
     3386        Also, you cannot discard the snapshot if it stores hard disks
     3387        (of any type) having differencing child hard disks that belong
     3388        to other machines. Such snapshots can be only discarded after
     3389        you discard all snapshots of other machines containing "foreign"
     3390        child disks, or detach these "foreign" child disks from machines
     3391        they are attached to.
     3392
     3393        One particular example of the snapshot storing normal hard disks
     3394        is the first snapshot of a virtual machine that had normal hard
     3395        disks attached when taking the snapshot. Be careful when
     3396        discarding such snapshots because this implicitly commits
     3397        changes (made since the snapshot being discarded has been taken)
     3398        to normal hard disks (as described above), which may be not what
     3399        you want.
     3400
     3401        The virtual machine is put to
     3402        the <link to="MachineState::Discarding">Discarding</link> state until
     3403        the discard operation is completed.
     3404

     3414          machines, whose hard disks are directly or indirectly based on the
     3415          hard disks of discarded snapshot, must be powered off.
     3416        </note>
     3417        <note>
     3418          Merging hard disk contents can be very time and disk space
     3419          consuming, if these disks are big in size and have many
     3420          children. However, if the snapshot being discarded is the last
     3421          (head) snapshot on the branch, the operation will be rather

    4333             The ISnapshot interface represents a snapshot of the virtual
    4334             machine.
    4335 
    4336             The <i>snapshot</i> stores all the information about a virtual
    4337             machine necessary to bring it to exactly the same state as it was at
    4338             the time of taking the snapshot. The snapshot includes:
    4339 
    4340             <ul>
    4341             <li>all settings of the virtual machine (i.e. its hardware
    4342             configuration: RAM size, attached hard disks, etc.)
    4343             </li>
    4344             <li>the execution state of the virtual machine (memory contents,
    4345             CPU state, etc.).
    4346             </li>
    4347             </ul>
    4348 
    4349             Snapshots can be <i>offline</i> (taken when the VM is powered off)
    4350             or <i>online</i> (taken when the VM is running). The execution
    4351             state of the offline snapshot is called a <i>zero execution state</i>
    4352             (it doesn't actually contain any information about memory contents
    4353             or the CPU state, assuming that all hardware is just powered off).
    4354 
    4355             <h3>Snapshot branches</h3>
    4356 
    4357             Snapshots can be chained. Chained snapshots form a branch where
    4358             every next snapshot is based on the previous one. This chaining is
    4359             mostly related to hard disk branching (see <link to="IHardDisk"/>
    4360             description). This means that every time a new snapshot is created,
    4361             a new differencing hard disk is implicitly created for all normal
    4362             hard disks attached to the given virtual machine. This allows to
    4363             fully restore hard disk contents when the machine is later reverted
    4364             to a particular snapshot.
    4365 
    4366             In the current implelemtation, multiple snapshot branches within one
    4367             virtual machine are not allowed. Every machine has a signle branch,
    4368             and <link to="IConsole::takeSnapshot()"/> operation adds a new
    4369             snapshot to the top of that branch.
    4370 
    4371             Existings snapshots can be discarded using

    4374             <h3>Current snapshot</h3>
    4375 
    4376             Every virtual machine has a current snapshot, identified by
    4377             <link to="IMachine::currentSnapshot"/>. This snapshot is used as
    4378             a base for the <i>current machine state</i> (see below), to the effect
    4379             that all normal hard disks of the machine and its execution
    4380             state are based on this snapshot.
    4381 
    4382             In the current implementation, the current snapshot is always the
    4383             last taken snapshot (i.e. the head snapshot on the branch) and it
    4384             cannot be changed.
    4385 
    4386             The current snapshot is <tt>null</tt> if the machine doesn't have
    4387             snapshots at all; in this case the current machine state is just
    4388             current settings of this machine plus its current execution state.
    4389 
    4390             <h3>Current machine state</h3>
    4391 
    4392             The current machine state is what represened by IMachine instances
    4393             got directly from IVirtualBox using <link
    4394             to="IVirtualBox::getMachine()">getMachine()</link>, <link
    4395             to="IVirtualBox::findMachine()">findMachine()</link>, etc. (as
    4396             opposed to instances returned by <link to="ISnapshot::machine"/>).
    4397             This state is always used when the machine is <link
    4398             to="IConsole::powerUp"> powered on</link>.
    4399 
    4400             The current machine state also includes the current execution state.
    4401             If the machine is being currently executed
    4402             (<link to="IMachine::state"/> is <link to="MachineState::Running"/>
    4403             and above), its execution state is just what's happening now.
    4404             If it is powered off (<link to="MachineState::PoweredOff"/> or
    4405             <link to="MachineState::Aborted"/>), it has a zero execution state.
    4406             If the machine is saved (<link to="MachineState::Saved"/>), its
    4407             execution state is what saved in the execution state file
    4408             (<link to="IMachine::stateFilePath"/>).
    4409 
    4410             If the machine is in the saved state, then, next time it is powered
    4411             on, its execution state will be fully restored from the saved state
    4412             file and the execution will continue from the point where the state
    4413             was saved.
    4414 
    4415             Similarly to snapshots, the current machine state can be discarded
    4416             using <link to="IConsole::discardCurrentState()"/>.

     4350    <desc>
     4351      The ISnapshot interface represents a snapshot of the virtual
     4352      machine.
     4353
     4354      The <i>snapshot</i> stores all the information about a virtual
     4355      machine necessary to bring it to exactly the same state as it was at
     4356      the time of taking the snapshot. The snapshot includes:
     4357
     4358      <ul>
     4359        <li>all settings of the virtual machine (i.e. its hardware
     4360          configuration: RAM size, attached hard disks, etc.)
     4361        </li>
     4362        <li>the execution state of the virtual machine (memory contents,
     4363          CPU state, etc.).
     4364        </li>
     4365      </ul>
     4366
     4367      Snapshots can be <i>offline</i> (taken when the VM is powered off)
     4368      or <i>online</i> (taken when the VM is running). The execution
     4369      state of the offline snapshot is called a <i>zero execution state</i>
     4370      (it doesn't actually contain any information about memory contents
     4371      or the CPU state, assuming that all hardware is just powered off).
     4372
     4373      <h3>Snapshot branches</h3>
     4374
     4375      Snapshots can be chained. Chained snapshots form a branch where
     4376      every next snapshot is based on the previous one. This chaining is
     4377      mostly related to hard disk branching (see <link to="IHardDisk"/>
     4378      description). This means that every time a new snapshot is created,
     4379      a new differencing hard disk is implicitly created for all normal
     4380      hard disks attached to the given virtual machine. This allows to
     4381      fully restore hard disk contents when the machine is later reverted
     4382      to a particular snapshot.
     4383
     4384      In the current implelemtation, multiple snapshot branches within one
     4385      virtual machine are not allowed. Every machine has a signle branch,
     4386      and <link to="IConsole::takeSnapshot()"/> operation adds a new
     4387      snapshot to the top of that branch.
     4388
     4389      Existings snapshots can be discarded using
     4390      <link to="IConsole::discardSnapshot()"/>.
     4391
     4392      <h3>Current snapshot</h3>
     4393
     4394      Every virtual machine has a current snapshot, identified by
     4395      <link to="IMachine::currentSnapshot"/>. This snapshot is used as
     4396      a base for the <i>current machine state</i> (see below), to the effect
     4397      that all normal hard disks of the machine and its execution
     4398      state are based on this snapshot.
     4399
     4400      In the current implementation, the current snapshot is always the
     4401      last taken snapshot (i.e. the head snapshot on the branch) and it
     4402      cannot be changed.
     4403
     4404      The current snapshot is <tt>null</tt> if the machine doesn't have
     4405      snapshots at all; in this case the current machine state is just
     4406      current settings of this machine plus its current execution state.
     4407
     4408      <h3>Current machine state</h3>
     4409
     4410      The current machine state is what represened by IMachine instances got
     4411      directly from IVirtualBox
     4412      using <link
     4413      to="IVirtualBox::getMachine()">getMachine()</link>, <link
     4414      to="IVirtualBox::findMachine()">findMachine()</link>, etc. (as opposed
     4415      to instances returned by <link to="ISnapshot::machine"/>).  This state
     4416      is always used when the machine is <link to="IConsole::powerUp"> powered
     4417      on</link>.
     4418
     4419      The current machine state also includes the current execution state.
     4420      If the machine is being currently executed
     4421      (<link to="IMachine::state"/> is <link to="MachineState::Running"/>
     4422      and above), its execution state is just what's happening now.
     4423      If it is powered off (<link to="MachineState::PoweredOff"/> or
     4424      <link to="MachineState::Aborted"/>), it has a zero execution state.
     4425      If the machine is saved (<link to="MachineState::Saved"/>), its
     4426      execution state is what saved in the execution state file
     4427      (<link to="IMachine::stateFilePath"/>).
     4428
     4429      If the machine is in the saved state, then, next time it is powered
     4430      on, its execution state will be fully restored from the saved state
     4431      file and the execution will continue from the point where the state
     4432      was saved.
     4433
     4434      Similarly to snapshots, the current machine state can be discarded
     4435      using <link to="IConsole::discardCurrentState()"/>.

     4664      The IHardDisk interface represents a virtual hard disk drive
     4665      used by virtual machines.
     4666
     4667      The virtual hard disk drive virtualizes the hard disk hardware and
     4668      looks like a regular hard disk inside the virtual machine and
     4669      the guest OS.
     4670
     4671      <h3>Storage Types</h3>
     4672
     4673      The <link to="HardDiskStorageType">storage type</link> of the
     4674      virtual hard disk determines where and how it stores its data
     4675      (sectors). Currently, the following storage types are supported:
     4676
     4677      <ul>
     4678
     4679        <li>
     4680          <i>Virtual Disk Image (VDI)</i>, a regular file in the file system
     4681          of the host OS (represented by the <link to="IVirtualDiskImage"/>
     4682          interface). This file has a special format optimized so that unused
     4683          sectors of data occupy much less space than on a physical hard disk.
     4684        </li>
     4685
     4686        <li>
     4687          <i>iSCSI Remote Disk</i>, a disk accessed via the Internet SCSI
     4688          protocol over a TCP/IP network link (represented by the
     4689          <link to="IISCSIHardDisk"/> interface).
     4690        </li>
     4691
     4692        <li>
     4693          <i>VMware VMDK Image</i>, a regular file in the file system of the
     4694          host OS (represented by the <link to="IVMDKImage"/> interface).
     4695        </li>
     4696
     4697      </ul>
     4698
     4699      The storage type of the particular hard disk object is indicated by
     4700      the <link to="#storageType"/> property.
     4701
     4702      Each storage type is represented by its own interface (as shown
     4703      above), that allows to query and set properties and perform
     4704      operations specific to that storage type. When an IHardDisk object
     4705      reports it uses some particular storage type, it also guaranteed to
     4706      support the corresponding interface which you can query. And vice
     4707      versa, every object that supports a storage-specific interface, also
     4708      supports IHardDisk.
     4709
     4710      <h3>Virtual Hard Disk Types</h3>
     4711
     4712      The <link to="HardDiskType">type</link> of the virtual hard disk
     4713      determines how it is attached to the virtual machine when you call
     4714      <link to="IMachine::attachHardDisk()"/> and what happens to it when
     4715      a <link to="ISnapshot">snapshot</link> of the virtual machine is
     4716      taken.
     4717
     4718      There are three types of virtual hard disks:
     4719
     4720      <ul>
     4721        <li><i>Normal</i></li>
     4722        <li><i>Immutable</i></li>
     4723        <li><i>Writethrough</i></li>
     4724      </ul>
     4725
     4726      The virtual disk type is indicated by the <link to="#type"/>
     4727      property. Each of the above types is described in detail further
     4728      down.
     4729
     4730      There is also a forth, "hidden" virtual disk type:
     4731      <i>Differencing</i>. It is "hidden" because you cannot directly
     4732      create hard disks of this type -- they are automatically created by
     4733      VirtualBox when necessary.
     4734
     4735      <b>Differencing Hard Disks</b>
     4736
     4737      Unlike disks of other types (that are similar to real hard disks),
     4738      the differencing hard disk does not store the full range of data
     4739      sectors. Instead, it stores only a subset of sectors of some other
     4740      disk that were changed since the differencing hard disk has been
     4741      created. Thus, every differencing hard disk has a parent hard disk
     4742      it is linked to, and represents the difference between the initial
     4743      and the current hard disk state. A differencing hard disk can be
     4744      linked to another differencing hard disk -- this way, differencing
     4745      hard disks can form a branch of changes. More over, a given virtual
     4746      hard disk can have more than one differencing hard disk linked to
     4747      it.
     4748
     4749      A disk the differencing hard disk is linked to (or, in other words,
     4750      based on) is called a <i>parent</i> hard disk and is accessible through
     4751      the <link to="#parent"/> property. Similarly, all existing differencing
     4752      hard disks for a given parent hard disk are called its <i>child</i> hard
     4753      disks (and accessible through the <link to="#children"/> property).
     4754
     4755      All differencing hard disks use Virtual Disk Image files to store
     4756      changed sectors. They have the <link to="#type"/> property set to
     4757      Normal, but can be easily distinguished from normal hard disks using
     4758      the <link to="#parent"/> property: all differencing hard disks have
     4759      a parent, while all normal hard disks don't.
     4760
     4761      When the virtual machine makes an attempt to read a sector that is
     4762      missing in a differencing hard disk, its parent is accessed to
     4763      resolve the sector in question. This process continues until the
     4764      sector is found, or until the root hard disk is encountered, which
     4765      always contains all sectors. As a consequence,
     4766
     4767      <ul>
     4768
     4769        <li>
     4770          The virtual hard disk geometry seen by the guest OS is
     4771          always defined by the root hard disk.
     4772        </li>
     4773
     4774        <li>
     4775          All hard disks on a branch, up to the root, must be
     4776          <link to="#accessible"/> for a given differencing hard disk in order
     4777          to let it function properly when the virtual machine is
     4778          running.
     4779        </li>
     4780
     4781      </ul>
     4782
     4783      Differencing hard disks can be implicitly created by VirtualBox in
     4784      the following cases:
     4785
     4786      <ul>
     4787
     4788        <li>
     4789          When a hard disk is <i>indirectly</i> attached to the virtual
     4790          machine using <link to="IMachine::attachHardDisk()"/>.  In this
     4791          case, all disk writes performed by the guest OS will go to the
     4792          created diffferencing hard disk, as opposed to the
     4793          <i>direct</i> attachment, where all changes are written to the
     4794          attached hard disk itself.
     4795        </li>
     4796
     4797        <li>
     4798          When a <link to="ISnapshot">snapshot</link> of the virtual machine
     4799          is taken. After that, disk writes to hard disks the differencing
     4800          ones have been created for, will be directed to those differencing
     4801          hard disks, to preserve the contents of the original disks.
     4802        </li>
     4803
     4804      </ul>
     4805
     4806      Whether to create a differencing hard disk or not depends on the
     4807      type of the hard disk attached to the virtual machine. This is
     4808      explained below.
     4809
     4810      Note that in the current implementation, only the
     4811      <link to="VirtualDiskImage"/> storage type is used to
     4812      represent differencing hard disks. In other words, all
     4813      differencing hard disks are <link to="IVirtualDiskImage"/>
     4814      objects.
     4815
     4816      <b>Normal Hard Disks</b>
     4817
     4818      Normal hard disks are the most commonly used virtual hard disk. A
     4819      normal hard disk is attached to the machine directly if it is not
     4820      already attached to some other machine. Otherwise, an attempt to
     4821      make an indirect attachment through a differencing hard disk will be
     4822      made. This attempt will fail if the hard disk is attached to a
     4823      virtual machine without snapshots (because it's impossible to create
     4824      a differencing hard disk based on a hard disk that is subject to
     4825      change).
     4826
     4827      When an indirect attachment takes place, in the simplest case, where
     4828      the machine the hard disk is being attached to doesn't have
     4829      snapshots, the differencing hard disk will be based on the normal
     4830      hard disk being attached. Otherwise, the first (i.e. the most
     4831      recent) descendant of the given normal hard disk found in the
     4832      current snapshot branch (starting from the current snapshot and
     4833      going up to the root) will be actually used as a base.
     4834
     4835      Note that when you detach an indirectly attached hard disk from the
     4836      machine, the created differencing hard disk image is simply
     4837      <b>deleted</b>, so <b>all changes are lost</b>. If you attach the
     4838      same disk again, a clean differencing disk will be created based on
     4839      the most recent child, as described above.
     4840
     4841      When taking a snapshot, the contents of all normal hard disks (and
     4842      all differencing disks whose roots are normal hard disks) currently
     4843      attached to the virtual machine is preserved by creating
     4844      differencing hard disks based on them.
     4845
     4846      <b>Immutable Hard Disks</b>
     4847
     4848      Immutable hard disks can be used to provide a sort of read-only
     4849      access. An immutable hard disk is always attached indirectly. The
     4850      created differencing hard disk is automatically wiped out (recreated
     4851      from scratch) every time you power off the virtual machine. Thus,
     4852      the contents of the immutable disk remains unchanged between runs.
     4853
     4854      Detaching an immutable hard disk deletes the differencing disk
     4855      created for it, with the same effect as in case with normal hard
     4856      disks.
     4857
     4858      When taking a snapshot, the differencing part of the immutable
     4859      hard disk is cloned (i.e. copied to a separate Virtual Disk Image
     4860      file) without any changes. This is necessary to preserve the exact
     4861      virtual machine state when you create an online snapshot.
     4862
     4863      <b>Writethrough Hard Disks</b>
     4864
     4865      Hard disks of this type are always attached directly. This means
     4866      that every given writethrough hard disk can be attached only to one
     4867      virtual machine at a time.
     4868
     4869      It is impossible to take a snapshot of a virtual machine with the
     4870      writethrough hard disk attached, because taking a snapshot implies
     4871      saving the execution state and preserving the contents of all hard
     4872      disks, but writethrough hard disks cannot be preserved. Preserving
     4873      hard disk contents is necessary to ensure the guest OS stored in the
     4874      snapshot will get the same hard disk state when restored, which is
     4875      especially important when it has open file handles or when there are
     4876      cached files and directories stored in memory.
     4877
     4878      <h3>Creating, Opening and Registering Hard Disks</h3>
     4879
     4880      Non-differencing hard disks are either created from scratch using
     4881      <link to="IVirtualBox::createHardDisk()"/> or opened from a VDI file
     4882      using <link to="IVirtualBox::openVirtualDiskImage()"/> (only for hard
     4883      disks using the VirtualDiskImage storage type). Once a hard disk is
     4884      created or opened, it needs to be registered using
     4885      <link to="IVirtualBox::registerHardDisk()"/> to make it available for
     4886      attaching to virtual machines. See the documentation of individual
     4887      interfaces for various storage types to get more information.
     4888
     4889      Differencing hard disks are never created explicitly and cannot
     4890      be registered or unregistered; they are automatically registered
     4891      upon creation and deregistered when deleted.
     4892
     4893      <h3>More about Indirect Hard Disk Attachments</h3>
     4894
     4895      Normally, when you attach a hard disk to the virtual machine, and then
     4896      query the corresponding attachment using
     4897      <link to="IMachine::getHardDisk()"/> or
     4898      <link to="IMachine::hardDiskAttachments"/> you will get the same hard
     4899      disk object, whose UUID you passed earlier to
     4900      <link to="IMachine::attachHardDisk()"/>. However, when an indirect
     4901      attachment takes place, calling <link to="IMachine::getHardDisk()"/>
     4902      will return a differencing hard disk object, that is either based on the
     4903      attached hard disk or on another differencing hard disk, the attached
     4904      hard disk is eventually a root for (as described above). In both cases
     4905      the returned hard disk object is the object the virtual machine actually
     4906      uses to perform disk writes to.
     4907
     4908      Regardless of whether the attachment is direct or indirect, the
     4909      <link to="#machineId"/> property of the attached disk will contain an
     4910      UUID of the machine object <link to="IMachine::attachHardDisk()"/>
     4911      has been called on.
     4912
     4913      Note that both <link to="IMachine::attachHardDisk()"/> and
     4914      <link to="IMachine::detachHardDisk()"/> are <i>lazy</i> operations. In
     4915      particular, this means that when an indirect attachment is made,
     4916      differencing hard disks are not created until machine settings are
     4917      committed using <link to="IMachine::saveSettings()"/>. Similarly, when a
     4918      differencing hard disk is detached, it is not deleted until
     4919      <link to="IMachine::saveSettings()"/> is called. Calling
     4920      <link to="IMachine::discardSettings()"/> cancels all lazy attachments or
     4921      detachments made since the last commit and effectively restores the
     4922      previous set of hard disks.
     4923
     4924      <h3>Hard Disk Accessibility</h3>
     4925
     4926      The <link to="#accessible"/> attribute of the hard disk object
     4927      defines the accessibility state of the respective hard disk storage
     4928      (for example, the VDI file for IVirtualDiskImage objects). If the
     4929      value of this attribute is <tt>false</tt> then some hard disk
     4930      attributes may contain invalid or outdated values (for example, the
     4931      virtual or the actual hard disk size) until a new accessibility
     4932      check is done that returns <tt>true</tt> (see the attribute
     4933      description for more details).
     4934
     4935      <note>
     4936        Because of the possible slowness of the accessibility check,
     4937        it is not implicitly performed upon the VirtualBox server startup
     4938        (to prevent the application freeze). In partcular, this means that
     4939        if you try to read hard disk properties that depend on the
     4940        accessibility state without first reading the value of the
     4941        <link to="#accessible"/> attribute and ensuring it's value is
     4942        <tt>true</tt>, you will get wrong (zero) values.

     5211      data.
     5212
     5213      Hard disks using virtual disk images can be either opened using

     5219
     5220      When a new hard disk object is created from scatch, an image file for it
     5221      is not automatically created. To do it, you need to specify a

     5223      <link to="#createFixedImage()"/> or <link to="#createDynamicImage()"/>.
     5224      When it is done, the hard disk object can be registered by calling
     5225      <link to="IVirtualBox::registerHardDisk()"/> and then

     5464      The IVMDKImage interface represents <link to="IHardDisk">virtual hard
     5465      disks</link> that use VMware Virtual Machine Disk image files to store
     5466      hard disk data.
     5467
     5468      Hard disks using VMDK images can be either opened using
     5469      <link to="IVirtualBox::openHardDisk()"/> or created from
     5470      scratch using <link to="IVirtualBox::createHardDisk()"/>.
     5471
     5472      Objects that support this interface also support the
     5473      <link to="IHardDisk"/> interface.
     5474
     5475      When a new hard disk object is created from scatch, an image file for it
     5476      is not automatically created. To do it, you need to specify a
     5477      valid <link to="#filePath">file path</link>, and call
     5478      <link to="#createFixedImage()"/> or <link to="#createDynamicImage()"/>.
     5479      When it is done, the hard disk object can be registered by calling
     5480      <link to="IVirtualBox::registerHardDisk()"/> and then
     5481      <link to="IMachine::attachHardDisk()">attached</link> to
     5482      virtual machines.
     5483
     5484      The <link to="IHardDisk::description">description</link>
     5485      of the VMDK hard disk is stored in the VirtualBox
     5486      configuration file, so it can be changed (at appropriate
     5487      times) even when
     5488      <link to="IHardDisk::accessible">accessible</link> returns
     5489      <tt>false</tt>.  However, the hard disk must not be
     5490      attached to a running virtual machine.
     5491
     5492      <note>
     5493        In the current imlementation, the type of all VMDK hard disks
     5494        is <link to="HardDiskType::WritethroughHardDisk">Writethrough</link>
     5495        and cannot be changed.

     5658
     5659      The <link to="#accessible"/> attribute of the image object
     5660      defines the accessibility state of the image file. If the

     5662      attributes may contain invalid or outdated values (for example, the
     5663      the image file size) until a new accessibility

     5665
     5666      <note>
     5667        Because of the possible slowness of the accessibility check,
     5668        it is not implicitly performed upon the VirtualBox server startup
     5669        (to prevent the application freeze). In partcular, this means that
     5670        if you try to read image properties that depend on the
     5671        accessibility state without first reading the value of the
     5672        <link to="#accessible"/> attribute and ensuring it's value is
     5673        <tt>true</tt>, you will get wrong (zero) values.

     5693        The accessibility check is performed automatically every time

    4645             The IHardDisk interface represents a virtual hard disk drive
    4646             used by virtual machines.
    4647 
    4648             The virtual hard disk drive virtualizes the hard disk hardware and
    4649             looks like a regular hard disk inside the virtual machine and
    4650             the guest OS.

    4652             <h3>Storage Types</h3>
    4653 
    4654             The <link to="HardDiskStorageType">storage type</link> of the
    4655             virtual hard disk determines where and how it stores its data
    4656             (sectors). Currently, the following storage types are supported:
    4657 
    4658             <ul>
    4659 
    4660                 <li><i>Virtual Disk Image (VDI)</i>, a regular file in the file
    4661                 system of the host OS (represented by the <link
    4662                 to="IVirtualDiskImage"/> interface). This file has a special
    4663                 format optimized so that unused sectors of data occupy much less
    4664                 space than on a physical hard disk.</li>
    4665 
    4666                 <li><i>iSCSI Remote Disk</i>, a disk accessed via the Internet
    4667                 SCSI protocol over a TCP/IP network link (represented by the
    4668                 <link to="IISCSIHardDisk"/> interface).</li>
    4669 
    4670                 <li><i>VMware VMDK Image</i>, a regular file in the file
    4671                 system of the host OS (represented by the <link
    4672                 to="IVMDKImage"/> interface).</li>
    4673 
    4674             </ul>
    4675 
    4676             The storage type of the particular hard disk object is indicated by
    4677             the <link to="#storageType"/> property.
    4678 
    4679             Each storage type is represented by its own interface (as shown
    4680             above), that allows to query and set properties and perform
    4681             operations specific to that storage type. When an IHardDisk object
    4682             reports it uses some particular storage type, it also guaranteed to
    4683             support the corresponding interface which you can query. And vice
    4684             versa, every object that supports a storage-specific interface, also
    4685             supports IHardDisk.
    4686 
    4687             <h3>Virtual Hard Disk Types</h3>
    4688 
    4689             The <link to="HardDiskType">type</link> of the virtual hard disk
    4690             determines how it is attached to the virtual machine when you call
    4691             <link to="IMachine::attachHardDisk()"/> and what happens to it when
    4692             a <link to="ISnapshot">snapshot</link> of the virtual machine is
    4693             taken.
    4694 
    4695             There are three types of virtual hard disks:
    4696 
    4697             <ul>
    4698                 <li><i>Normal</i></li>
    4699                 <li><i>Immutable</i></li>
    4700                 <li><i>Writethrough</i></li>
    4701             </ul>
    4702 
    4703             The virtual disk type is indicated by the <link to="#type"/>
    4704             property. Each of the above types is described in detail further
    4705             down.
    4706 
    4707             There is also a forth, "hidden" virtual disk type:
    4708             <i>Differencing</i>. It is "hidden" because you cannot directly
    4709             create hard disks of this type -- they are automatically created by
    4710             VirtualBox when necessary.
    4711 
    4712             <b>Differencing Hard Disks</b>
    4713 
    4714             Unlike disks of other types (that are similar to real hard disks),
    4715             the differencing hard disk does not store the full range of data
    4716             sectors. Instead, it stores only a subset of sectors of some other
    4717             disk that were changed since the differencing hard disk has been
    4718             created. Thus, every differencing hard disk has a parent hard disk
    4719             it is linked to, and represents the difference between the initial
    4720             and the current hard disk state. A differencing hard disk can be
    4721             linked to another differencing hard disk -- this way, differencing
    4722             hard disks can form a branch of changes. More over, a given virtual
    4723             hard disk can have more than one differencing hard disk linked to
    4724             it.
    4725 
    4726             A disk the differencing hard disk is linked to (or, in other
    4727             words, based on) is called a <i>parent</i> hard disk and is
    4728             accessible through the <link to="#parent"/> property. Similarly, all
    4729             existing differencing hard disks for a given parent hard disk are
    4730             called its <i>child</i> hard disks (and accessible through the <link
    4731             to="#children"/> property).
    4732 
    4733             All differencing hard disks use Virtual Disk Image files to store
    4734             changed sectors. They have the <link to="#type"/> property set to
    4735             Normal, but can be easily distinguished from normal hard disks using
    4736             the <link to="#parent"/> property: all differencing hard disks have
    4737             a parent, while all normal hard disks don't.
    4738 
    4739             When the virtual machine makes an attempt to read a sector that is
    4740             missing in a differencing hard disk, its parent is accessed to
    4741             resolve the sector in question. This process continues until the
    4742             sector is found, or until the root hard disk is encountered, which
    4743             always contains all sectors. As a consequence,
    4744 
    4745             <ul>
    4746 
    4747                 <li>The virtual hard disk geometry seen by the guest OS is
    4748                 always defined by the root hard disk.</li>
    4749 
    4750                 <li>All hard disks on a branch, up to the root, must be <link
    4751                 to="#accessible"/> for a given differencing hard disk in order
    4752                 to let it function properly when the virtual machine is
    4753                 running.</li>
    4754 
    4755             </ul>
    4756 
    4757             Differencing hard disks can be implicitly created by VirtualBox in
    4758             the following cases:
    4759 
    4760             <ul>
    4761 
    4762                 <li>When a hard disk is <i>indirectly</i> attached to the
    4763                 virtual machine using <link to="IMachine::attachHardDisk()"/>.
    4764                 In this case, all disk writes performed by the guest OS will go
    4765                 to the created diffferencing hard disk, as opposed to the
    4766                 <i>direct</i> attachment, where all changes are written to the
    4767                 attached hard disk itself.</li>
    4768 
    4769                 <li>When a <link to="ISnapshot">snapshot</link> of the virtual
    4770                 machine is taken. After that, disk writes to hard disks the
    4771                 differencing ones have been created for, will be directed to
    4772                 those differencing hard disks, to preserve the contents of the
    4773                 original disks.</li>
    4774 
    4775             </ul>
    4776 
    4777             Whether to create a differencing hard disk or not depends on the
    4778             type of the hard disk attached to the virtual machine. This is
    4779             explained below.
    4780 
    4781             Note that in the current implementation, only the
    4782             <link to="VirtualDiskImage"/> storage type is used to
    4783             represent differencing hard disks. In other words, all
    4784             differencing hard disks are <link to="IVirtualDiskImage"/>
    4785             objects.
    4786 
    4787             <b>Normal Hard Disks</b>
    4788 
    4789             Normal hard disks are the most commonly used virtual hard disk. A
    4790             normal hard disk is attached to the machine directly if it is not
    4791             already attached to some other machine. Otherwise, an attempt to
    4792             make an indirect attachment through a differencing hard disk will be
    4793             made. This attempt will fail if the hard disk is attached to a
    4794             virtual machine without snapshots (because it's impossible to create
    4795             a differencing hard disk based on a hard disk that is subject to
    4796             change).
    4797 
    4798             When an indirect attachment takes place, in the simplest case, where
    4799             the machine the hard disk is being attached to doesn't have
    4800             snapshots, the differencing hard disk will be based on the normal
    4801             hard disk being attached. Otherwise, the first (i.e. the most
    4802             recent) descendant of the given normal hard disk found in the
    4803             current snapshot branch (starting from the current snapshot and
    4804             going up to the root) will be actually used as a base.
    4805 
    4806             Note that when you detach an indirectly attached hard disk from the
    4807             machine, the created differencing hard disk image is simply
    4808             <b>deleted</b>, so <b>all changes are lost</b>. If you attach the
    4809             same disk again, a clean differencing disk will be created based on
    4810             the most recent child, as described above.
    4811 
    4812             When taking a snapshot, the contents of all normal hard disks (and
    4813             all differencing disks whose roots are normal hard disks) currently
    4814             attached to the virtual machine is preserved by creating
    4815             differencing hard disks based on them.
    4816 
    4817             <b>Immutable Hard Disks</b>
    4818 
    4819             Immutable hard disks can be used to provide a sort of read-only
    4820             access. An immutable hard disk is always attached indirectly. The
    4821             created differencing hard disk is automatically wiped out (recreated
    4822             from scratch) every time you power off the virtual machine. Thus,
    4823             the contents of the immutable disk remains unchanged between runs.
    4824 
    4825             Detaching an immutable hard disk deletes the differencing disk
    4826             created for it, with the same effect as in case with normal hard
    4827             disks.
    4828 
    4829             When taking a snapshot, the differencing part of the immutable
    4830             hard disk is cloned (i.e. copied to a separate Virtual Disk Image
    4831             file) without any changes. This is necessary to preserve the exact
    4832             virtual machine state when you create an online snapshot.
    4833 
    4834             <b>Writethrough Hard Disks</b>
    4835 
    4836             Hard disks of this type are always attached directly. This means
    4837             that every given writethrough hard disk can be attached only to one
    4838             virtual machine at a time.
    4839 
    4840             It is impossible to take a snapshot of a virtual machine with the
    4841             writethrough hard disk attached, because taking a snapshot implies
    4842             saving the execution state and preserving the contents of all hard
    4843             disks, but writethrough hard disks cannot be preserved. Preserving
    4844             hard disk contents is necessary to ensure the guest OS stored in the
    4845             snapshot will get the same hard disk state when restored, which is
    4846             especially important when it has open file handles or when there are
    4847             cached files and directories stored in memory.
    4848 
    4849             <h3>Creating, Opening and Registering Hard Disks</h3>
    4850 
    4851             Non-differencing hard disks are either created from scratch using
    4852             <link to="IVirtualBox::createHardDisk()"/> or opened from a VDI file
    4853             using <link to="IVirtualBox::openVirtualDiskImage()"/> (only for
    4854             hard disks using the VirtualDiskImage storage type). Once a hard
    4855             disk is created or opened, it needs to be registered using <link
    4856             to="IVirtualBox::registerHardDisk()"/> to make it available for
    4857             attaching to virtual machines. See the documentation of individual
    4858             interfaces for various storage types to get more information.
    4859 
    4860             Differencing hard disks are never created explicitly and cannot
    4861             be registered or unregistered; they are automatically registered
    4862             upon creation and deregistered when deleted.
    4863 
    4864             <h3>More about Indirect Hard Disk Attachments</h3>
    4865 
    4866             Normally, when you attach a hard disk to the virtual machine, and
    4867             then query the corresponding attachment using <link
    4868             to="IMachine::getHardDisk()"/> or <link
    4869             to="IMachine::hardDiskAttachments"/> you will get the same hard disk
    4870             object, whose UUID you passed earlier to <link
    4871             to="IMachine::attachHardDisk()"/>. However, when an indirect
    4872             attachment takes place, calling <link to="IMachine::getHardDisk()"/>
    4873             will return a differencing hard disk object, that is either based on
    4874             the attached hard disk or on another differencing hard disk, the
    4875             attached hard disk is eventually a root for (as described above). In
    4876             both cases the returned hard disk object is the object the virtual
    4877             machine actually uses to perform disk writes to.
    4878 
    4879             Regardless of whether the attachment is direct or indirect, the
    4880             <link to="#machineId"/> property of the attached disk will contain an
    4881             UUID of the machine object <link to="IMachine::attachHardDisk()"/>
    4882             has been called on.
    4883 
    4884             Note that both <link to="IMachine::attachHardDisk()"/> and <link
    4885             to="IMachine::detachHardDisk()"/> are <i>lazy</i> operations. In
    4886             particular, this means that when an indirect attachment is made,
    4887             differencing hard disks are not created until machine settings are
    4888             committed using <link to="IMachine::saveSettings()"/>. Similarly,
    4889             when a differencing hard disk is detached, it is not deleted until
    4890             <link to="IMachine::saveSettings()"/> is called. Calling <link
    4891             to="IMachine::discardSettings()"/> cancels all lazy attachments or
    4892             detachments made since the last commit and effectively restores the
    4893             previous set of hard disks.
    4894 
    4895             <h3>Hard Disk Accessibility</h3>
    4896 
    4897             The <link to="#accessible"/> attribute of the hard disk object
    4898             defines the accessibility state of the respective hard disk storage
    4899             (for example, the VDI file for IVirtualDiskImage objects). If the
    4900             value of this attribute is <tt>false</tt> then some hard disk
    4901             attributes may contain invalid or outdated values (for example, the
    4902             virtual or the actual hard disk size) until a new accessibility
    4903             check is done that returns <tt>true</tt> (see the attribute
    4904             description for more details).
    4905 
    4906             <note>
    4907             Because of the possible slowness of the accessibility check,
    4908             it is not implicitly performed upon the VirtualBox server startup
    4909             (to prevent the application freeze). In partcular, this means that
    4910             if you try to read hard disk properties that depend on the
    4911             accessibility state without first reading the value of the
    4912             <link to="#accessible"/> attribute and ensuring it's value is
    4913             <tt>true</tt>, you will get wrong (zero) values.

     6018          a mouse button as follows:
     6019          <table>
     6020            <tr><td>Bit 0 (<tt>0x01</tt>)</td><td>left mouse button</td></tr>
     6021            <tr><td>Bit 1 (<tt>0x02</tt>)</td><td>right mouse button</td></tr>

     6023          </table>
     6024          A value of <tt>1</tt> means the corresponding button is pressed.

    5013                 The storage, for example, can be unaccessible if it doesn't exist
    5014                 or if it is placed on a network resource that is not available
    5015                 by the time this attribute is read.

    5017                 In the current implementation, the value of this property is

    5020 
    5021                 The accessibility check is performed automatically every time
    5022                 this attribute is read. You should keep it in mind that this check
    5023                 may be slow and can block the calling thread for a long time (for
    5024                 example, if the network resourse where the hard disk storage is
    5025                 located is down).
    5026 
    5027                 The following attributes of the hard disk object are considered

    5031                 <li><link to="#actualSize"/></li>
    5032                 </ul>
    5033                 Individual hard disk storage type interfaces may define
    5034                 additional attributes that depend on the accessibility state.

    5429 
    5430             When a new hard disk object is created from scatch, an image file

    5603 
    5604             The <link to="#accessible"/> attribute of the image object
    5605             defines the accessibility state of the image file. If the
    5606             value of this attribute is <tt>false</tt> then some image
    5607             attributes may contain invalid or outdated values (for example, the
    5608             the image file size) until a new accessibility
    5609             check is done that returns <tt>true</tt>.
    5610 
    5611             <note>
    5612             Because of the possible slowness of the accessibility check,
    5613             it is not implicitly performed upon the VirtualBox server startup
    5614             (to prevent the application freeze). In partcular, this means that
    5615             if you try to read image properties that depend on the
    5616             accessibility state without first reading the value of the
    5617             <link to="#accessible"/> attribute and ensuring it's value is
    5618             <tt>true</tt>, you will get wrong (zero) values.

     6070          </table>
     6071          A value of <tt>1</tt> means the corresponding button is pressed.

     6188        Requests a size and pixel format change.
     6189
     6190        The IFramebuffer implementation should try to setup
     6191        a memory buffer suitable for the given pixel format
     6192        and line size.
     6193        The buffer must be page aligned, must contain
     6194        whole number of pages, and one should be able
     6195        to lock it to obtain physical addresses of pages.
     6196        (Note: this method is currently not supported,
     6197        use the below mentioned vram pointer!)
     6198
     6199        If the requested pixel format is not supported,
     6200        or a PixelFormatDefault is requested,
     6201        a default format is set. In that case the memory
     6202        buffer does not have to be aligned and lockable.
     6203
     6204        The callee is also allowed to use the guest video memory
     6205        buffer (pointed to by the @a vram parameter) directly instead
     6206        of allocating its own buffer. To indicate that the framebuffer
     6207        wants to use the guest video memory, its <link to="#address"/>
     6208        implementation must return the same address as it gets in
     6209        the @a vram parameter of this method.
     6210
     6211        For non linear modes (such as text and standard VGA), the @a
     6212        vram parameter is @c NULL and must not be used. When it's not
     6213        NULL, it is recommended to use it to access the guest video
     6214        memory instead of creating a separate buffer as it will at
     6215        least remove one copy operation.
     6216
     6217        The caller checks if the call was successful
     6218        via the <link to="#pixelFormat"/> property.

     6221          This method is called by IDisplay under the IFramebuffer

    5757             The IFloppyImage interface represents a file containing the image
    5758             of a floppy disk.
    5759 
    5760             <h3>Image Accessibility</h3>
    5761 
    5762             The <link to="#accessible"/> attribute of the image object
    5763             defines the accessibility state of the image file. If the
    5764             value of this attribute is <tt>false</tt> then some image
    5765             attributes may contain invalid or outdated values (for example, the
    5766             the image file size) until a new accessibility
    5767             check is done that returns <tt>true</tt>.
    5768 
    5769             <note>
    5770             Because of the possible slowness of the accessibility check,
    5771             it is not implicitly performed upon the VirtualBox server startup
    5772             (to prevent the application freeze). In partcular, this means that
    5773             if you try to read image properties that depend on the
    5774             accessibility state without first reading the value of the
    5775             <link to="#accessible"/> attribute and ensuring it's value is
    5776             <tt>true</tt>, you will get wrong (zero) values.
    5777             </note>
    5778 
     6245          Can the VM start using the new framebuffer immediately
     6246          after this method returns or it should wait for
     6247          <link to="IDisplay::resizeCompleted()"/>.

    5793                 on a network share that is not available by the time
    5794                 this property is read.
    5795 
    5796                 The accessibility check is performed automatically every time

     6253      <desc>
     6254        Returns whether the given acceleration operation is supported
     6255        by the IFramebuffer implementation. If not, the display object
     6256        will not attempt to call the corresponding IFramebuffer entry
     6257        point. Even if an operation is indicated to supported, the
     6258        IFramebuffer implementation always has the option to return non
     6259        supported from the corresponding acceleration method in which
     6260        case the operation will be performed by the display engine. This
     6261        allows for reduced IFramebuffer implementation complexity where
     6262        only common cases are handled.

     6272        the video mode (or for some reason not willing), it should
     6273        return false. Usually this method is called when the guest
     6274        asks the VMM device whether a given video mode is supported
     6275        so the information returned is directly exposed to the guest.
     6276        It is important that this method returns very quickly.

    6152                 wants to use the guest video memory, its <link to="#address"/>
    6153                 implementation must return the same address as it gets in
    6154                 the @a vram parameter of this method.
    6155 
    6156                 For non linear modes (such as text and standard VGA), the @a
    6157                 vram parameter is @c NULL and must not be used. When it's not
    6158                 NULL, it is recommended to use it to access the guest video
    6159                 memory instead of creating a separate buffer as it will at
    6160                 least remove one copy operation.

    6162                 The caller checks if the call was successful

    6496                 if no device has been allocated. On Linux, setting this refers to a permanent TAP
    6497                 device. However, a file descriptor has precedence over the interface name on Linux.
    6498                 Note that when VBox allocates a TAP device, this property will not be set, i.e. the
    6499                 interface name would have to be determined using the file descriptor and /proc/self/fd.

     6977    <desc>
     6978      The IUSBDeviceFilter interface represents an USB device filter used
     6979      to perform actions on a group of USB devices.
     6980
     6981      This type of filters is used by running virtual machines to
     6982      automatically capture selected USB devices once they are physically
     6983      attached to the host computer.
     6984
     6985      A USB device is matched to the given device filter if and only if all
     6986      attributes of the device match the corresponding attributes of the
     6987      filter (that is, attributes are joined together using the logical AND
     6988      operation). On the other hand, all together, filters in the list of
     6989      filters carry the semantics of the logical OR operation. So if it is
     6990      desirable to create a match like "this vendor id OR this product id",
     6991      one needs to create two filters and specify "any match" (see below)
     6992      for unused attributes.
     6993
     6994      All filter attributes used for matching are strings. Each string
     6995      is an expression representing a set of values of the corresponding
     6996      device attribute, that will match the given filter. Currently, the
     6997      following filtering expressions are supported:
     6998
     6999      <ul>
     7000        <li><i>Interval filters</i>. Used to specify valid intervals for
     7001          integer device attributes (Vendor ID, Product ID and Revision).
     7002          The format of the string is:
     7003
     7004          <tt>int:((m)|([m]-[n]))(,(m)|([m]-[n]))*</tt>
     7005
     7006          where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
     7007          (starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
     7008          or decimal (otherwise) form, so that <tt>m &lt; n</tt>. If <tt>m</tt>
     7009          is ommitted before a dash (<tt>-</tt>), the minimum possible integer
     7010          is assumed; if <tt>n</tt> is ommitted after a dash, the maximum
     7011          possible integer is assummed.
     7012        </li>
     7013        <li><i>Boolean filters</i>. Used to specify acceptable values for
     7014          boolean device attributes. The format of the string is:
     7015
     7016          <tt>true|false|yes|no|0|1</tt>
     7017
     7018        </li>
     7019        <li><i>Exact match</i>. Used to specify a single value for the given
     7020          device attribute. Any string that does't start with <tt>int:</tt>
     7021          represents the exact match. String device attributes are compared to
     7022          this string including case of symbols. Integer attributes are first
     7023          converted to a string (see individual filter attributes) and then
     7024          compared ignoring case.
     7025
     7026        </li>
     7027        <li><i>Any match</i>. Any value of the corresponding device attribute
     7028          will match the given filter. An empty or <tt>null</tt> string is
     7029          used to construct this type of filtering expressions.
     7030
     7031        </li>
     7032      </ul>
     7033
     7034      <note>
     7035        On the Windows host platform, interval filters are not currently
     7036        available. Also all string filter attributes
     7037        (<link to="#manufacturer"/>, <link to="#product"/>,
     7038        <link to="#serialNumber"/>) are ignored, so they behave as
     7039        <i>any match</i> no matter what string expression is specified.

     7082        trailing zeroes).
     7083        Note that for interval filters, it's best to use the hexadecimal
     7084        form, because the revision is stored as a 16 bit packed BCD value;
     7085        so the expression <tt>int:0x0100-0x0199</tt> will match any

     7143      filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
     7144      either ignore the device, or put ot to #USBDeviceHeld state, or do
     7145      nothing. Unless the device is ignored by global filters, filters of
     7146      all currently running guests (<link to="IUSBController::DeviceFilters"/>)
     7147      are activated that can put it to #USBDeviceCaptured state.
     7148
     7149      If the device was ignored by global filters, or didn't match
     7150      any filters at all (including guest ones), it is handled by the host
     7151      in a normal way. In this case, the device state is determined by
     7152      the host and can be one of #USBDeviceUnavailable, #USBDeviceBusy or
     7153      #USBDeviceAvailable, depending on the current device usage.
     7154
     7155      Besides auto-capturing based on filters, the device can be manually
     7156      captured by guests (<link to="IConsole::attachUSBDevice()"/>) if its
     7157      state is #USBDeviceBusy, #USBDeviceAvailable or #USBDeviceHeld.
     7158
     7159      <note>
     7160        Due to differences in USB stack implementations in Linux and Win32,
     7161        states #USBDeviceBusy and #USBDeviceAvailable are applicable
     7162        only to the Linux version of the product. This also means that
     7163        (<link to="IConsole::attachUSBDevice()"/>) can only succeed
     7164        on Win32 if the device state is #USBDeviceHeld.

    6923             The IUSBDeviceFilter interface represents an USB device filter used
    6924             to perform actions on a group of USB devices.
    6925 
    6926             This type of filters is used by running virtual machines to
    6927             automatically capture selected USB devices once they are physically
    6928             attached to the host computer.
    6929 
    6930             A USB device is matched to the given device filter if and only if all
    6931             attributes of the device match the corresponding attributes of the
    6932             filter (that is, attributes are joined together using the logical AND
    6933             operation). On the other hand, all together, filters in the list of
    6934             filters carry the semantics of the logical OR operation. So if it is
    6935             desirable to create a match like "this vendor id OR this product id",
    6936             one needs to create two filters and specify "any match" (see below)
    6937             for unused attributes.
    6938 
    6939             All filter attributes used for matching are strings. Each string
    6940             is an expression representing a set of values of the corresponding
    6941             device attribute, that will match the given filter. Currently, the
    6942             following filtering expressions are supported:
    6943 
    6944             <ul>
    6945             <li><i>Interval filters</i>. Used to specify valid intervals for
    6946             integer device attributes (Vendor ID, Product ID and Revision).
    6947             The format of the string is:
    6948 
    6949             <tt>int:((m)|([m]-[n]))(,(m)|([m]-[n]))*</tt>
    6950 
    6951             where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
    6952             (starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
    6953             or decimal (otherwise) form, so that <tt>m &lt; n</tt>. If <tt>m</tt>
    6954             is ommitted before a dash (<tt>-</tt>), the minimum possible integer
    6955             is assumed; if <tt>n</tt> is ommitted after a dash, the maximum
    6956             possible integer is assummed.
    6957             </li>
    6958             <li><i>Boolean filters</i>. Used to specify acceptable values for
    6959             boolean device attributes. The format of the string is:
    6960 
    6961             <tt>true|false|yes|no|0|1</tt>
    6962 
    6963             </li>
    6964             <li><i>Exact match</i>. Used to specify a single value for the given
    6965             device attribute. Any string that does't start with <tt>int:</tt>
    6966             represents the exact match. String device attributes are compared to
    6967             this string including case of symbols. Integer attributes are first
    6968             converted to a string (see individual filter attributes) and then
    6969             compared ignoring case.
    6970 
    6971             </li>
    6972             <li><i>Any match</i>. Any value of the corresponding device attribute
    6973             will match the given filter. An empty or <tt>null</tt> string is
    6974             used to construct this type of filtering expressions.
    6975 
    6976             </li>
    6977             </ul>
    6978 
    6979             <note>
    6980                 On the Windows host platform, interval filters are not currently
    6981                 available. Also all string filter attributes
    6982                 (<link to="#manufacturer"/>, <link to="#product"/>,
    6983                 <link to="#serialNumber"/>) are ignored, so they behave as
    6984                 <i>any match</i> no matter what string expression is specified.

    7028                 Note that for interval filters, it's best to use the hexadecimal
    7029                 form, because the revision is stored as a 16 bit packed BCD value;
    7030                 so the expression <tt>int:0x0100-0x0199</tt> will match any

    7082             USB device state. This enumeration represents all possible states
    7083             of the USB device physically attached to the host computer regarding
    7084             its state on the host computer and availability to guest computers
    7085             (all currently running virtual machines).
    7086 
    7087             Once a supported USB device is attached to the host, global USB
    7088             filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
    7089             either ignore the device, or put ot to #USBDeviceHeld state, or do
    7090             nothing. Unless the device is ignored by global filters, filters of
    7091             all currently running guests (<link to="IUSBController::DeviceFilters"/>)
    7092             are activated that can put it to #USBDeviceCaptured state.
    7093 
    7094             If the device was ignored by global filters, or didn't match
    7095             any filters at all (including guest ones), it is handled by the host
    7096             in a normal way. In this case, the device state is determined by
    7097             the host and can be one of #USBDeviceUnavailable, #USBDeviceBusy or
    7098             #USBDeviceAvailable, depending on the current device usage.
    7099 
    7100             Besides auto-capturing based on filters, the device can be manually
    7101             captured by guests (<link to="IConsole::attachUSBDevice()"/>) if its

    7104             <note>
    7105                 Due to differences in USB stack implementations in Linux and Win32,
    7106                 states #USBDeviceBusy and #USBDeviceAvailable are applicable
    7107                 only to the Linux version of the product. This also means that

    7109                 on Win32 if the device state is #USBDeviceHeld.

    7424             The ISharedFolder interface represents a folder in the host
    7425             computer's file system accessible from a guest OS running inside a
    7426             virtual machine using an associated logical name.
    7427 
    7428             There are three types of shared folders:
    7429             <ul>
    7430                 <li>permanent (<link to="IMachine::sharedFolders"/>)</li>
    7431                 <li>transient (<link to="IConsole::sharedFolders"/>)</li>

    7433             </ul>
    7434 
    7435             For a given virtual machine, both permanently and transiently
    7436             shared folders have the same logical name space which also includes
    7437             all globally shared folders. Thus, every folder in this name space
    7438             must have an unique logical name. Note that permanent and transient
    7439             shares of other machines are in different name spaces, so they don't
    7440             have to have unique names.
