# versions of QEMU should set this to a non-empty string. The

#
# This command will cause the QEMU process to exit gracefully. While every

#
# Stop all guest VCPU execution.
#
# Since: 0.14.0
#
# 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

#
# Notes: A guest may or may not respond to this command. This command

# Returns: If successful, nothing
#
# Notes: This command will succeed if the guest is currently running. It

#
# Example:
#
# -> { "execute": "cont" }

# If no balloon device is present, DeviceNotActive
#
# Notes: This command just issues a request to the guest. When it returns,

# 1) A primitive type such as 'u8', 'u16', 'bool', 'str', or 'double'.
# These types are mapped to the appropriate JSON type.
#
# 2) A child type in the form 'child<subtype>' where subtype is a qdev
# device type name. Child properties create the composition tree.
#
# 3) A link type in the form 'link<subtype>' where subtype is a qdev

# This command will get a property from a object model path and return the

#
# @path: The path within the object model. There are two forms of supported
# paths--absolute and partial paths.
#
# Absolute paths are derived from the root object and can follow child<>
# or link<> properties. Since they can follow link<> properties, they
# can be arbitrarily long. Absolute paths look like absolute filenames
# and are prefixed with a leading slash.
#
# Partial paths look like relative filenames. They do not begin
# with a prefix. The matching rules for partial paths are subtle but
# designed to make specifying objects easy. At each level of the
# composition tree, the partial path is matched as an absolute path.
# The first match is not returned. At least two matches are searched
# for. A successful result is only returned if only one match is
# found. If more than one match is found, a flag is return to
# indicate that the match was ambiguous.
#
# @property: The property name to read
#
# Returns: The property value. The type depends on the property
# type. child<> and link<> properties are returned as #str
# pathnames. All integer property types (u8, u16, etc) are
# returned as #int.

# @change:
#
# This command is multiple commands multiplexed together.
#
# @device: This is normally the name of a block device but it may also be 'vnc'.
# when it's 'vnc', then sub command depends on @target
#
# @target: If @device is a block device, then this is the new filename.
# If @device is 'vnc', then if the value 'password' selects the vnc
# change password command. Otherwise, this specifies a new server URI
# address to listen to for VNC connections.
#
# @arg: If @device is a block device, then this is an optional format to open
# the device with.
# If @device is 'vnc' and @target is 'password', this is the new VNC
# password to set. See change-vnc-password for additional notes.

#
# Notes: When this command completes, the device may not be removed from the

# @dump-guest-memory:
#
# Dump guest's memory to vmcore. It is a synchronous operation that can take
# very long depending on the amount of guest memory.
#
# @paging: if true, do paging to get guest's memory mapping. This allows
# using gdb to process the core file.
#
# IMPORTANT: this option can make QEMU allocate several gigabytes
# of RAM. This can happen for a large guest, or a
# malicious guest pretending to be large.
#
# Also, paging=true has the following limitations:
#
# 1. The guest may be in a catastrophic state or can have corrupted
# memory, which cannot be trusted
# 2. The guest can be in real-mode even if paging is enabled. For
# example, the guest uses ACPI to sleep, and ACPI sleep state
# goes in real-mode
# 3. Currently only supported on i386 and x86_64.
#
# @protocol: the filename or file descriptor of the vmcore. The supported
# protocols are:
#
# 1. file: the protocol starts with "file:", and the following
# string is the file's path.
# 2. fd: the protocol starts with "fd:", and the following string
# is the fd's name.
#
# @detach: if true, QMP will return immediately rather than
# waiting for the dump to finish. The user can track progress
# using "query-dump". (since 2.6).
#
# @begin: if specified, the starting physical address.
#
# @length: if specified, the memory size, in bytes. If you don't
# want to dump all guest's memory, please specify the start @begin
# and @length
#
# @format: if specified, the format of guest memory dump. But non-elf
# format is conflict with paging and filter, ie. @paging, @begin and
# @length is not allowed to be specified with non-elf @format at the
# same time (since 2.0)
#
# Note: All boolean arguments default to false
