Enumeration Type Documentation

enum TSBool

Boolean variable having a third state, default.

Interface ID:
{523FF64D-842A-4B1A-80E7-C311B028CB3A}
Enumerator:
False 
True 
Default 

Virtual machine execution state.

This enumeration represents possible values of the IMachine::state attribute.

Interface ID:
{73BF04D0-7C4F-4684-9ABF-D65A9AD74343}
Enumerator:
Null  null value.

null value which may also mean "no device".

Never used by the API.

Note:
This value is not allowed for IConsole::getDeviceActivity
Also means "not attached".

Also means "dummy audio driver".

Also means "no authentication".

PoweredOff  The machine is not running.
Saved  The machine is not currently running, but the execution state of the machine has been saved to an external file when it was running.

Note:
No any machine settings can be altered when the machine is in this state.
Aborted  A process that run the machine has abnormally terminated.

Other than that, this value is equivalent to PoweredOff.

Running  The machine is currently being executed.

Note:
This value can be used in comparison expressions: all state values below it describe a virtual machine that is not currently being executed (i.e., it is completely out of action).

For whoever decides to touch this enum: In order to keep the aforementioned comparisons valid, this state must immediately preceed the Paused state.

Paused  The execution of the machine has been paused.

Note:
This value can be used in comparison expressions: all state values above it represent unstable states of the running virtual machine. Unless explicitly stated otherwise, no machine settings can be altered when it is in one of the unstable states.

For whoever decides to touch this enum: In order to keep the aforementioned comparisons valid, this state must immediately follow the Running state.

Stuck  The execution of the machine has reached the "Guru Meditation" condition.

This condition indicates an internal VMM failure which may happen as a result of either an unhandled low-level virtual hardware exception or one of the recompiler exceptions (such as the too-many-traps condition).

Starting  The machine is being started after powering it on from a zero execution state.
Stopping  The machine is being normally stopped (after explicitly powering it off, or after the guest OS has initiated a shutdown sequence).
Saving  The machine is saving its execution state to a file as a result of calling IConsole::saveState or an online snapshot of the machine is being taken using IConsole::takeSnapshot.
Restoring  The execution state of the machine is being restored from a file after powering it on from a saved execution state.
Discarding  A snapshot of the machine is being discarded after calling IConsole::discardSnapshot or its current state is being discarded after IConsole::discardCurrentState.

Session state.

This enumeration represents possible values of IMachine::sessionState and ISession::state attributes. Idividual value descriptions contain the appropriate meaning for every case.

Interface ID:
{CF2700C0-EA4B-47AE-9725-7810114B94D8}

Note:
This value is not allowed for IConsole::getDeviceActivity

Also means "no authentication".

Closed  The machine has no open sessions (IMachine::sessionState); the session is closed (ISession::state).

Open  The machine has an open direct session (IMachine::sessionState); the session is open (ISession::state).

Spawning  A new (direct) session is being opened for the machine as a result of IVirtualBox::openRemoteSession() call (IMachine::sessionState); the session is currently being opened as a result of IVirtualBox::openRemoteSession() call (ISession::state).

Closing  The direct session is being closed (IMachine::sessionState); the session is being closed (ISession::state).

This enumeration represents possible values of the ISession::type attribute.

enum PortMode

The PortMode enumeration represents possible communicaton modes for the virtual serial port device.

Enumerator:
Disconnected  Virtual device is not attached to any real host device.

HostDevice  Virtual device is attached to a host device.

USB device state.

This enumeration represents all possible states of the USB device physically attached to the host computer regarding its state on the host computer and availability to guest computers (all currently running virtual machines).

Once a supported USB device is attached to the host, global USB filters (IHost::USBDeviceFilters) are activated. They can either ignore the device, or put ot to Held state, or do nothing. Unless the device is ignored by global filters, filters of all currently running guests (IUSBController::deviceFilters) are activated that can put it to Captured state.

If the device was ignored by global filters, or didn't match any filters at all (including guest ones), it is handled by the host in a normal way. In this case, the device state is determined by the host and can be one of Unavailable, Busy or Available, depending on the current device usage.

Besides auto-capturing based on filters, the device can be manually captured by guests (IConsole::attachUSBDevice()) if its state is Busy, Available or Held.

Note:
Due to differences in USB stack implementations in Linux and Win32, states Busy and Available are applicable only to the Linux version of the product. This also means that (IConsole::attachUSBDevice()) can only succeed on Win32 if the device state is Held.
