 ##
 # @stop:
 #
 # Stop guest VM execution.
 #
 # Since: 0.14
 #
 # .. note:: This function will succeed even if the guest is already in
 #    the stopped state.  In "inmigrate" state, it will ensure that the
 #    guest remains paused once migration finishes, as if the ``-S``
 #    option was passed on the command line.
 #
 #    In the "suspended" state, it will completely stop the VM and cause
 #    a transition to the "paused" state.  (Since 9.0)
 #
 # Example:
 #
 #     -> { "execute": "stop" }
 #     <- { "return": {} }
 ##
 { 'command': 'stop' }

 ##
 # @cont:
 #
 # Resume guest VM execution.
 #
 # Since: 0.14
 #
 # .. note:: This command will succeed if the guest is currently running.
 #    It will also succeed if the guest is in the "inmigrate" state; in
 #    this case, the effect of the command is to make sure the guest
 #    starts once migration finishes, removing the effect of the ``-S``
 #    command line option if it was passed.
 #
 #    If the VM was previously suspended, and not been reset or woken,
 #    this command will transition back to the "suspended" state.  (Since
 #    9.0)
 #
 # Example:
 #
 #     -> { "execute": "cont" }
 #     <- { "return": {} }
 ##
 { 'command': 'cont' }

 ##
 # @x-exit-preconfig:
 #
 # Exit from "preconfig" state
 #
 # This command makes QEMU exit the preconfig state and proceed with VM
 # initialization using configuration data provided on the command line
 # and via the QMP monitor during the preconfig state.  The command is
 # only available during the preconfig state (i.e. when the --preconfig
 # command line option was in use).
 #
 # Features:
 #
 # @unstable: This command is experimental.
 #
 # Since: 3.0
 #
 # Example:
 #
 #     -> { "execute": "x-exit-preconfig" }
 #     <- { "return": {} }
 ##
 { 'command': 'x-exit-preconfig', 'allow-preconfig': true,

 ##
 # @human-monitor-command:
 #
 # Execute a command on the human monitor and return the output.
 #
 # @command-line: the command to execute in the human monitor
 #
 # @cpu-index: The CPU to use for commands that require an implicit CPU
 #
 # Features:
 #
 # @savevm-monitor-nodes: If present, HMP command savevm only snapshots
 #     monitor-owned nodes if they have no parents.  This allows the
 #     use of 'savevm' with -blockdev.  (since 4.2)
 #
 # Returns: the output of the command as a string
 #
 # Since: 0.14
 #
 # .. note:: This command only exists as a stop-gap.  Its use is highly
 #    discouraged.  The semantics of this command are not guaranteed:
 #    this means that command names, arguments and responses can change
 #    or be removed at ANY time.  Applications that rely on long term
 #    stability guarantees should NOT use this command.
 #
 #    Known limitations:
 #
 #    * This command is stateless, this means that commands that
 #      depend on state information (such as getfd) might not work.
 #
 #    * Commands that prompt the user for data don't currently work.
 #
 # Example:
 #
 #     -> { "execute": "human-monitor-command",
 #          "arguments": { "command-line": "info kvm" } }
 #     <- { "return": "kvm support: enabled\r\n" }

 # @getfd:
 #
 # Receive a file descriptor via SCM rights and assign it a name
 #
 # @fdname: file descriptor name
 #
 # Since: 0.14
 #
 # .. note:: If @fdname already exists, the file descriptor assigned to
 #    it will be closed and replaced by the received file descriptor.
 #
 #    The 'closefd' command can be used to explicitly close the file
 #    descriptor when it is no longer needed.

 # and assign it a name (the SOCKET is associated with a CRT file
 # descriptor)

 #
 #    The 'closefd' command can be used to explicitly close the file

	# .. note:: This function will succeed even if the guest is already in
	# the stopped state. In "inmigrate" state, it will ensure that the
	# guest remains paused once migration finishes, as if the ``-S``
	# option was passed on the command line.
	#
	# In the "suspended" state, it will completely stop the VM and cause
	# a transition to the "paused" state. (Since 9.0)
	#
	# Example:
	#
	# -> { "execute": "stop" }
	# <- { "return": {} }
	##

	##
	# @cont:
	#
	# Resume guest VM execution.
	#
	# Since: 0.14
	#
	# .. note:: This command will succeed if the guest is currently running.
	# It will also succeed if the guest is in the "inmigrate" state; in
	# this case, the effect of the command is to make sure the guest
	# starts once migration finishes, removing the effect of the ``-S``
	# command line option if it was passed.
	#
	# If the VM was previously suspended, and not been reset or woken,
	# this command will transition back to the "suspended" state. (Since
	# 9.0)
	#
	# Example:
	#
	# -> { "execute": "cont" }
	# <- { "return": {} }
	##

	# @x-exit-preconfig:

	# and via the QMP monitor during the preconfig state. The command is
	# only available during the preconfig state (i.e. when the --preconfig
