# @stop:
#
# Stop all guest VCPU execution.
#
# Since: 0.14
#
# Notes: This function will succeed even if the guest is already in the stopped

# remains paused once migration finishes, as if the -S option was
# passed on the command line.

#
# 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.

cli: add --preconfig option This option allows pausing QEMU in the new RUN_STATE_PRECONFIG state, allowing the configuration of QEMU from QMP before the machine jumps into board initialization code of machine_run_board_init() The intent is to allow management to query machine state and additionally configure it using previous query results within one QEMU instance (i.e. eliminate the need to start QEMU twice, 1st to query board specific parameters and 2nd for actual VM start using query results for additional parameters). The new option complements -S option and could be used with or without it. The difference is that -S pauses QEMU when the machine is completely initialized with all devices wired up and ready to execute guest code (QEMU needs only to unpause VCPUs to let guest execute its code), while the "preconfig" option pauses QEMU early before board specific init callback (machine_run_board_init) is executed and allows the configuration of machine parameters which will be used by board init code. When early introspection/configuration is done, command 'exit-preconfig' should be used to exit RUN_STATE_PRECONFIG and transition to the next requested state (i.e. if -S is used then QEMU will pause the second time when board/device initialization is completed or start guest execution if -S isn't provided on CLI) PS: Initially 'preconfig' is planned to be used for configuring numa topology depending on board specified possible cpus layout.

# @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",
