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: + +-> data issued by the Client +<- Server data response + +Please, refer to the QMP specification (QMP/qmp-spec.txt) for detailed +information on the Server command and response formats. + +NOTE: This document is temporary and will be replaced soon. + +1. 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) + +2. Regular Commands +=================== + +Server's responses in the examples below are always a success response, please +refer to the QMP specification for more details on error responses. + +EQMP + + { + .name = "quit", + .args_type = "", + .mhandler.cmd_new = qmp_marshal_input_quit, + }, + +SQMP +quit +---- + +Quit the emulator. + +Arguments: None. + +Example: + +-> { "execute": "quit" } +<- { "return": {} } + +EQMP + + { + .name = "eject", + .args_type = "force:-f,device:B", + .mhandler.cmd_new = qmp_marshal_input_eject, + }, + +SQMP +eject +----- + +Eject a removable medium. + +Arguments: + +- force: force ejection (json-bool, optional) +- device: device name (json-string) + +Example: + +-> { "execute": "eject", "arguments": { "device": "ide1-cd0" } } +<- { "return": {} } + +Note: The "force" argument defaults to false. + +EQMP + + { + .name = "change", + .args_type = "device:B,target:F,arg:s?", + .mhandler.cmd_new = qmp_marshal_input_change, + }, + +SQMP +change +------ + +Change a removable medium or VNC configuration. + +Arguments: + +- "device": device name (json-string) +- "target": filename or item (json-string) +- "arg": additional argument (json-string, optional) + +Examples: + +1.
