   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
  25 #
  26 # Please, refer to the QMP specification (docs/interop/qmp-spec.txt) for
  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)
