5 # This document describes all commands currently supported by QMP.
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.
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.
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.
19 # Also, the following notation is used to denote data flow:
23 # | -> data issued by the Client
24 # | <- Server data response
26 # Please, refer to the QMP specification (docs/qmp-spec.txt) for
27 # detailed information on the Server command and response formats.
29 # = Stability Considerations
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.
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.
38 # If you're planning to adopt QMP, please observe the following:
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
44 # 2. DO NOT rely on anything which is not explicit documented
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)
