# -*- Mode: Python -*- ## # = 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/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) # ## # QAPI common definitions { 'include': 'qapi/common.json' } # QAPI crypto definitions { 'include': 'qapi/crypto.json' } # QAPI block definitions { 'include': 'qapi/block.json' } # QAPI event definitions { 'include': 'qapi/event.json' } # Tracing commands { 'include': 'qapi/trace.json' } # QAPI introspection { 'include': 'qapi/introspect.json' } ## # = QMP commands ## ## # @qmp_capabilities: # # Enable QMP capabilities. # # Arguments: None. # # Example: # # -> { "execute": "qmp_capabilities" } # <- { "return": {} } # # Notes: This command is valid exactly when first connecting: it must be # issued before any other command will be accepted, and will fail once the # monitor is accepting other commands.
