The generated QEMU QMP reference is now structured as follows:
1.1 Introduction
1.2 Stability Considerations
1.3 Common data types
1.4 Socket data types
1.5 VM run state
1.6 Cryptography
1.7 Block devices
1.7.1 Block core (VM unrelated)
1.7.2 QAPI block definitions (vm unrelated)
1.8 Character devices
1.9 Net devices
1.10 Rocker switch device
1.11 TPM (trusted platform module) devices
1.12 Remote desktop
1.12.1 Spice
1.12.2 VNC
1.13 Input
1.14 Migration
1.15 Transactions
1.16 Tracing
1.17 QMP introspection
1.18 Miscellanea
Section "1.18 Miscellanea" is still too big: it documents 134 symbols.
Section "1.7.1 Block core (VM unrelated)" is also rather big: 128
symbols. All the others are of reasonable size.

# = 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)
|
|

# @path: The path within the object model. There are two forms of supported

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

|
# 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

|

# 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

|
# 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

# 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
