3# = Introduction
4#
5# This document describes all commands currently supported by QMP.
6#
7# Most of the time their usage is exactly the same as in the user Monitor, this
8# means that any other document which also describe commands (the manpage,
9# QEMU's manual, etc) can and should be consulted.
10#
11# QMP has two types of commands: regular and query commands. Regular commands
12# usually change the Virtual Machine's state someway, while query commands just
13# return information. The sections below are divided accordingly.
14#
15# It's important to observe that all communication examples are formatted in
16# a reader-friendly way, so that they're easier to understand. However, in real
17# protocol usage, they're emitted as a single line.
18#
19# Also, the following notation is used to denote data flow:
20#
21# Example:
22#
23# | -> data issued by the Client
24# | <- Server data response
e3193601 25#
cfb41b88 26# Please, refer to the QMP specification (docs/interop/qmp-spec.txt) for
4d8bb958
MAL
27# detailed information on the Server command and response formats.
28#
29# = Stability Considerations
30#
31# The current QMP command set (described in this file) may be useful for a
32# number of use cases, however it's limited and several commands have bad
33# defined semantics, specially with regard to command completion.
34#
35# These problems are going to be solved incrementally in the next QEMU releases
36# and we're going to establish a deprecation policy for badly defined commands.
37#
38# If you're planning to adopt QMP, please observe the following:
39#
40# 1. The deprecation policy will take effect and be documented soon, please
41# check the documentation of each used command as soon as a new release of
42# QEMU is available
43#
44# 2. DO NOT rely on anything which is not explicit documented
45#
46# 3. Errors, in special, are not documented. Applications should NOT check
47# for specific errors classes or data (it's strongly recommended to only
48# check for the "error" key)
