##
# @RunState:
#
# An enumeration of VM run states.
#
# @debug: QEMU is running on a debugger
#
# @finish-migrate: guest is paused to finish the migration process
#
# @inmigrate: guest is paused waiting for an incoming migration.  Note
#             that this state does not tell whether the machine will start at the
#             end of the migration.  This depends on the command-line -S option and
#             any invocation of 'stop' or 'cont' that has happened since QEMU was
#             started.
#
# @internal-error: An internal error that prevents further guest execution
#                  has occurred
#
# @io-error: the last IOP has failed and the device is configured to pause
#            on I/O errors
#
# @paused: guest has been paused via the 'stop' command
#
# @postmigrate: guest is paused following a successful 'migrate'
#
# @prelaunch: QEMU was started with -S and guest has not started
#
# @restore-vm: guest is paused to restore VM state
#
# @running: guest is actively running
#
# @save-vm: guest is paused to save the VM state
#
# @shutdown: guest is shut down (and -no-shutdown is in use)
#
# @suspended: guest is suspended (ACPI S3)
#
# @watchdog: the watchdog action is configured to pause and has been triggered
#
# @guest-panicked: guest has been panicked as a result of guest OS panic
#
# @colo: guest is paused to save/restore VM state under colo checkpoint,
#        VM can not get into this state unless colo capability is enabled
#        for migration. (since 2.8)

# @SHUTDOWN:
#
# Emitted when the virtual machine has shut down, indicating that qemu is

#
# @guest: If true, the shutdown was triggered by a guest request (such as

#         rather than a host request (such as the QMP command system_reset).
