QMP Supported Commands |
|||
---------------------- |
|||
|
|||
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: |
|||
|
|||
-> 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. |
|||
|
|||
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. |
