   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
  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.

 860 Atomically operate on one or more block devices.  The only supported
 861 operation for now is snapshotting.  If there is any failure performing
 862 any of the operations, all snapshots for the group are abandoned, and
 863 the original disks pre-snapshot attempt are used.
 864
 865 A list of dictionaries is accepted, that contains the actions to be performed.
 866 For snapshots this is the device, the file to use for the new snapshot,
 867 and the format.  The default format, if not specified, is qcow2.
 868
 869 Each new snapshot defaults to being created by QEMU (wiping any
 870 contents if the file already exists), but it is also possible to reuse
 871 an externally-created file.  In the latter case, you should ensure that
 872 the new image file has the same contents as the current one; QEMU cannot
 873 perform any meaningful check.  Typically this is achieved by using the
 874 current image file as the backing file for the new image.
 875

 878 actions array:

 880       value is "blockdev-snapshot-sync". (json-string)

 882       of "type".  When "type" is "blockdev-snapshot-sync":
 883       - "device": device name to snapshot (json-string)
 884       - "snapshot-file": name of new image file (json-string)

1353 Notes:
1354
1355 (1) The Human Monitor is NOT an stable interface, this means that command
1356     names, arguments and responses can change or be removed at ANY time.
1357     Applications that rely on long term stability guarantees should NOT
1358     use this command
1359
1360 (2) Limitations:
1361
1362     o This command is stateless, this means that commands that depend
1363       on state information (such as getfd) might not work
1364
1365     o Commands that prompt the user for data (eg. 'cont' when the block
1366       device is encrypted) don't currently work
