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 (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.

SQMP
transaction
-----------
Atomically operate on one or more block devices. The only supported
operation for now is snapshotting. If there is any failure performing
any of the operations, all snapshots for the group are abandoned, and
the original disks pre-snapshot attempt are used.
A list of dictionaries is accepted, that contains the actions to be performed.
For snapshots this is the device, the file to use for the new snapshot,
and the format. The default format, if not specified, is qcow2.
Each new snapshot defaults to being created by QEMU (wiping any
contents if the file already exists), but it is also possible to reuse
an externally-created file. In the latter case, you should ensure that
the new image file has the same contents as the current one; QEMU cannot
perform any meaningful check. Typically this is achieved by using the
current image file as the backing file for the new image.
Arguments:
actions array:
- "type": the operation to perform. The only supported
value is "blockdev-snapshot-sync". (json-string)
- "data": a dictionary. The contents depend on the value
of "type". When "type" is "blockdev-snapshot-sync":
- "device": device name to snapshot (json-string)
- "snapshot-file": name of new image file (json-string)
- "format": format of new image (json-string, optional)

(NewImageMode, optional, default "absolute-paths")
Example:
-> { "execute": "transaction",
"arguments": { "actions": [

"format": "qcow2" } },
{ 'type': 'blockdev-snapshot-sync', 'data' : { "device": "ide-hd1",
"snapshot-file": "/some/place/my-image2",
"mode": "existing",
"format": "qcow2" } } ] } }

SQMP
blockdev-snapshot-sync
----------------------

snapshot image, default is qcow2.
Arguments:
- "device": device name to snapshot (json-string)
- "snapshot-file": name of new image file (json-string)
- "mode": whether and how QEMU should create the snapshot file

qmp_capabilities
----------------
Enable QMP capabilities.
Arguments: None.
Example:
-> { "execute": "qmp_capabilities" }
<- { "return": {} }
Note: This command must be issued before issuing any other command.

SQMP
human-monitor-command
---------------------
Execute a Human Monitor command.
Arguments:
- command-line: the command name and its arguments, just like the
Human Monitor's shell (json-string)
- cpu-index: select the CPU number to be used by commands which access CPU
data, like 'info registers'. The Monitor selects CPU 0 if this
argument is not provided (json-int, optional)
Example:
-> { "execute": "human-monitor-command", "arguments": { "command-line": "info kvm" } }
<- { "return": "kvm support: enabled\r\n" }
Notes:
(1) The Human Monitor is NOT an stable interface, this means that command
names, arguments and responses can change or be removed at ANY time.
Applications that rely on long term stability guarantees should NOT
use this command
(2) Limitations:
o This command is stateless, this means that commands that depend
on state information (such as getfd) might not work
o Commands that prompt the user for data (eg. 'cont' when the block
device is encrypted) don't currently work
