| 6 | QMP Supported Commands |
| 7 | ---------------------- |
| 8 | |
| 9 | This document describes all commands currently supported by QMP. |
| 10 | |
| 11 | Most of the time their usage is exactly the same as in the user Monitor, this |
| 12 | means that any other document which also describe commands (the manpage, |
| 13 | QEMU's manual, etc) can and should be consulted. |
| 14 | |
| 15 | QMP has two types of commands: regular and query commands. Regular commands |
| 16 | usually change the Virtual Machine's state someway, while query commands just |
| 17 | return information. The sections below are divided accordingly. |
| 18 | |
| 19 | It's important to observe that all communication examples are formatted in |
| 20 | a reader-friendly way, so that they're easier to understand. However, in real |
| 21 | protocol usage, they're emitted as a single line. |
| 22 | |
| 23 | Also, the following notation is used to denote data flow: |
| 24 | |
| 25 | -> data issued by the Client |
| 26 | <- Server data response |
| 27 | |
| 28 | Please, refer to the QMP specification (QMP/qmp-spec.txt) for detailed |
| 29 | information on the Server command and response formats. |
| 30 | |
| 31 | NOTE: This document is temporary and will be replaced soon. |
| 32 | |
| 33 | 1. Stability Considerations |
| 34 | =========================== |
| 35 | |
| 36 | The current QMP command set (described in this file) may be useful for a |
| 37 | number of use cases, however it's limited and several commands have bad |
| 38 | defined semantics, specially with regard to command completion. |
| 39 | |
| 40 | These problems are going to be solved incrementally in the next QEMU releases |
| 41 | and we're going to establish a deprecation policy for badly defined commands. |
| 42 | |
| 43 | If you're planning to adopt QMP, please observe the following: |
| 44 | |
Zhi Yong Wu | c20cdf8 | 2011-07-27 14:32:56 +0800 | [diff] [blame] | 45 | 1. The deprecation policy will take effect and be documented soon, please |
Luiz Capitulino | 82a56f0 | 2010-09-13 12:26:00 -0300 | [diff] [blame] | 46 | check the documentation of each used command as soon as a new release of |
| 47 | QEMU is available |
| 48 | |
| 49 | 2. DO NOT rely on anything which is not explicit documented |
| 50 | |
| 51 | 3. Errors, in special, are not documented. Applications should NOT check |
| 52 | for specific errors classes or data (it's strongly recommended to only |
| 53 | check for the "error" key) |
| 54 | |
| 55 | 2. Regular Commands |
| 56 | =================== |
| 57 | |
| 58 | Server's responses in the examples below are always a success response, please |
| 59 | refer to the QMP specification for more details on error responses. |

| 1087 | names, arguments and responses can change or be removed at ANY time. |
| 1088 | Applications that rely on long term stability guarantees should NOT |
| 1089 | use this command |
| 1090 | |
| 1091 | (2) Limitations: |
| 1092 | |
| 1093 | o This command is stateless, this means that commands that depend |
| 1094 | on state information (such as getfd) might not work |
| 1095 | |
| 1096 | o Commands that prompt the user for data (eg. 'cont' when the block |
| 1097 | device is encrypted) don't currently work |

| 2071 | query-balloon |
| 2072 | ------------- |
| 2073 | |
| 2074 | Show balloon information. |
| 2075 | |
| 2076 | Make an asynchronous request for balloon info. When the request completes a |
| 2077 | json-object will be returned containing the following data: |
| 2078 | |
| 2079 | - "actual": current balloon value in bytes (json-int) |
| 2080 | - "mem_swapped_in": Amount of memory swapped in bytes (json-int, optional) |
| 2081 | - "mem_swapped_out": Amount of memory swapped out in bytes (json-int, optional) |
| 2082 | - "major_page_faults": Number of major faults (json-int, optional) |
| 2083 | - "minor_page_faults": Number of minor faults (json-int, optional) |
| 2084 | - "free_mem": Total amount of free and unused memory in |
| 2085 | bytes (json-int, optional) |
| 2086 | - "total_mem": Total amount of available memory in bytes (json-int, optional) |
| 2087 | |
