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 |
|
45 |
1. The deprecation policy will take effect and be documented soon, please |
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. |

Notes: |
991 |
|
992 |
(1) The Human Monitor is NOT an stable interface, this means that command |
993 |
names, arguments and responses can change or be removed at ANY time. |
994 |
Applications that rely on long term stability guarantees should NOT |
995 |
use this command |
996 |
|
997 |
(2) Limitations: |
998 |
|
999 |
o This command is stateless, this means that commands that depend |
1000 |
on state information (such as getfd) might not work |
1001 |
|
1002 |
o Commands that prompt the user for data (eg. 'cont' when the block |
1003 |
device is encrypted) don't currently work |
1004 |
