# @query-iothreads:
#
# Returns a list of information about each iothread.

##
# @stop:
#
# Stop all guest VCPU execution.
#
# Since:  0.14
#
# Notes: 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.
#
# Example:
#
# -> { "execute": "stop" }
# <- { "return": {} }
#
##
{ 'command': 'stop' }

##
# @cont:
#
# Resume guest VCPU execution.
#
# Since:  0.14
#
# Returns:  If successful, nothing
#
# Notes: 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.
#
# 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).
#
# Since 3.0
#
# Returns: nothing
#
# 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
#
# Notes: 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
#
# Returns: Nothing on success
#
# Since: 0.14
#
# Notes: 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.
#
# Example:
#
# -> { "execute": "getfd", "arguments": { "fdname": "fd1" } }
# <- { "return": {} }

#          - If @fdset-id is a negative value, InvalidParameterValue
#
# Notes: The list of fd sets is shared by all monitor connections.
#
#        If @fdset-id is not specified, a new fd set will be created.
#
# Since: 1.2
#
# Example:
#
# -> { "execute": "add-fd", "arguments": { "fdset-id": 1 } }

#
# Since: 1.2
#
# Notes: The list of fd sets is shared by all monitor connections.
#
#        If @fd is not specified, all file descriptors in @fdset-id
#        will be removed.
