# = Introduction
|
|
#
|
|
# This document describes all commands currently supported by QMP.
|
|
#
|
|
# Most of the time their usage is exactly the same as in the user Monitor, this
|
|
# means that any other document which also describe commands (the manpage,
|
|
# QEMU's manual, etc) can and should be consulted.
|
|
#
|
|
# QMP has two types of commands: regular and query commands. Regular commands
|
|
# usually change the Virtual Machine's state someway, while query commands just
|
|
# return information. The sections below are divided accordingly.
|
|
#
|
|
# It's important to observe that all communication examples are formatted in
|
|
# a reader-friendly way, so that they're easier to understand. However, in real
|
|
# protocol usage, they're emitted as a single line.
|
|
#
|
|
# Also, the following notation is used to denote data flow:
|
|
#
|
|
# Example:
|
|
#
|
|
# | -> data issued by the Client
|
|
# | <- Server data response
|
|
#
|
|
# Please, refer to the QMP specification (docs/interop/qmp-spec.txt) for
|
|
# detailed information on the Server command and response formats.
|
|
#
|
|
# = Stability Considerations
|
|
#
|
|
# The current QMP command set (described in this file) may be useful for a
|
|
# number of use cases, however it's limited and several commands have bad
|
|
# defined semantics, specially with regard to command completion.
|
|
#
|
|
# These problems are going to be solved incrementally in the next QEMU releases
|
|
# and we're going to establish a deprecation policy for badly defined commands.
|
|
#
|
|
# If you're planning to adopt QMP, please observe the following:
|
|
#
|
|
# 1. The deprecation policy will take effect and be documented soon, please
|
|
# check the documentation of each used command as soon as a new release of
|
|
# QEMU is available
|
|
#
|
|
# 2. DO NOT rely on anything which is not explicit documented
|
|
#
|
|
# 3. Errors, in special, are not documented. Applications should NOT check
|
|
# for specific errors classes or data (it's strongly recommended to only
|
|
# check for the "error" key)
|
|

|
#
|
|
# Absolute paths are derived from the root object and can follow child<>
|

|
|
# 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

# @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

|
# 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).

#
|

|
|
# Baseline two CPU models, creating a compatible third model. The created
|
|
# model will always be a static, migration-safe CPU model (see "static"
|
|
# CPU model expansion for details).
|
|
#
|
|
# This interface can be used by tooling to create a compatible CPU model out
|
|
# two CPU models. The created CPU model will be identical to or a subset of
|
|
# both CPU models when comparing them. Therefore, the created CPU model is
|
|
# guaranteed to run where the given CPU models run.
|
|
#
|
|
# The result returned by this command may be affected by:
|
|
#
|
|
# * QEMU version: CPU models may look different depending on the QEMU version.
|
|
# (Except for CPU models reported as "static" in query-cpu-definitions.)
|
|
# * machine-type: CPU model may look different depending on the machine-type.
|
|
# (Except for CPU models reported as "static" in query-cpu-definitions.)
|
|
# * machine options (including accelerator): in some architectures, CPU models
|
|
# may look different depending on machine and accelerator options. (Except for
|
|
# CPU models reported as "static" in query-cpu-definitions.)
|
|
# * "-cpu" arguments and global properties: arguments to the -cpu option and
|
|
# global properties may affect expansion of CPU models. Using
|
|
# query-cpu-model-expansion while using these is not advised.
|
|
#
|
|
# Some architectures may not support baselining CPU models. s390x supports
|
|
# baselining CPU models.
|
|
#
|
|
# Returns: a CpuModelBaselineInfo. Returns an error if baselining CPU models is
