                        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.

            Whitespace *is* invalid.

Example:

-> { "execute": "ringbuf-write",
                "arguments": { "device": "foo",
                               "data": "abcdefgh",

            replaced.  Bug: replacement doesn't work.  Bug: can screw
            up on encountering NUL characters, after the ring buffer
            lost data, and when reading stops because the size limit
            is reached.

Example:

-> { "execute": "ringbuf-read",
                "arguments": { "device": "foo",

drive-backup
------------

Start a point-in-time copy of a block device to a new destination.  The
status of ongoing drive-backup operations can be checked with
query-block-jobs where the BlockJobInfo.type field has the value 'backup'.
The operation can be stopped before it has completed using the
block-job-cancel command.

Arguments:

- "device": the name of the device which should be copied.
            (json-string)
- "target": the target of the new image. If the file exists, or if it is a
            device, the existing file/device will be used as the new
            destination.  If it does not exist, a new file will be created.
            (json-string)
- "format": the format of the new destination, default is to probe if 'mode' is
            'existing', else the format of the source
            (json-string, optional)
- "sync": what parts of the disk image should be copied to the destination;
  possibilities include "full" for all the disk, "top" for only the sectors
  allocated in the topmost image, or "none" to only replicate new I/O
  (MirrorSyncMode).
- "mode": whether and how QEMU should create a new image
          (NewImageMode, optional, default 'absolute-paths')
- "speed": the maximum speed, in bytes per second (json-int, optional)
- "on-source-error": the action to take on an error on the source, default
                     'report'.  'stop' and 'enospc' can only be used
                     if the block device supports io-status.
                     (BlockdevOnError, optional)
- "on-target-error": the action to take on an error on the target, default
                     'report' (no limitations, since this applies to
                     a different block device than device).

SQMP
transaction
-----------

Atomically operate on one or more block devices.  The only supported operations
for now are drive-backup, internal and external snapshotting.  A list of
dictionaries is accepted, that contains the actions to be performed.
If there is any failure performing any of the operations, all operations
for the group are abandoned.

For external snapshots, the dictionary contains 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.

On failure, the original disks pre-snapshot attempt will be used.

For internal snapshots, the dictionary contains the device and the snapshot's
name.  If an internal snapshot matching name already exists, the request will
be rejected.  Only some image formats support it, for example, qcow2, rbd,
and sheepdog.

On failure, qemu will try delete the newly created internal snapshot in the
transaction.  When an I/O error occurs during deletion, the user needs to fix
it later with qemu-img or other command.

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)
      - "mode": whether and how QEMU should create the snapshot file
        (NewImageMode, optional, default "absolute-paths")
      When "type" is "blockdev-snapshot-internal-sync":
      - "device": device name to snapshot (json-string)
      - "name": name of the new snapshot (json-string)

The default value of the granularity is the image cluster size clamped
between 4096 and 65536, if the image format defines one.  If the format
does not define a cluster size, the default value of the granularity
is 65536.

- 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

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

query-migrate
-------------

Migration status.

Return a json-object. If migration is active there will be another json-object
with RAM migration status and if block migration is active another one with
block migration status.

The main json-object contains the following:

- "status": migration status (json-string)
     - Possible values: "active", "completed", "failed", "cancelled"
- "total-time": total amount of ms since migration started.  If
                migration has ended, it returns the total migration
                time (json-int)
- "setup-time" amount of setup time in milliseconds _before_ the
               iterations begin but _after_ the QMP command is issued.
               This is designed to provide an accounting of any activities
               (such as RDMA pinning) which may be expensive, but do not 
               actually occur during the iterative migration rounds 
               themselves. (json-int)
- "downtime": only present when migration has finished correctly
              total amount in ms for downtime that happened (json-int)
- "expected-downtime": only present while migration is active
                total amount in ms for downtime that was calculated on
                the last bitmap round (json-int)
- "ram": only present if "status" is "active", it is a json-object with the
  following RAM information:
         - "transferred": amount transferred in bytes (json-int)
         - "remaining": amount remaining to transfer in bytes (json-int)
         - "total": total amount of memory in bytes (json-int)
         - "duplicate": number of pages filled entirely with the same
            byte (json-int)
            These are sent over the wire much more efficiently.
         - "skipped": number of skipped zero pages (json-int)
         - "normal" : number of whole pages transferred.  I.e. they
            were not sent as duplicate or xbzrle pages (json-int)
         - "normal-bytes" : number of bytes transferred in whole
            pages. This is just normal pages times size of one page,
            but this way upper levels don't need to care about page
            size (json-int)
- "disk": only present if "status" is "active" and it is a block migration,
  it is a json-object with the following disk information:
         - "transferred": amount transferred in bytes (json-int)
         - "remaining": amount remaining to transfer in bytes json-int)
         - "total": total disk size in bytes (json-int)
- "xbzrle-cache": only present if XBZRLE is active.
  It is a json-object with the following XBZRLE information:
         - "cache-size": XBZRLE cache size in bytes
         - "bytes": number of bytes transferred for XBZRLE compressed pages
         - "pages": number of XBZRLE compressed pages
         - "cache-miss": number of XBRZRLE page cache misses
         - "overflow": number of times XBZRLE overflows.  This means
           that the XBZRLE encoding was bigger than just sent the
           whole page, and then we sent the whole page instead (as as
           normal page).

Examples:

1. Before the first migration

-> { "execute": "query-migrate" }
<- { "return": {} }

2. Migration is done and has succeeded

-> { "execute": "query-migrate" }

given NIC doesn't support rx-filter querying, or given net client
isn't a NIC.

The query will clear the event notification flag of each NIC, then qemu
will start to emit event to QMP monitor.

Each array entry contains the following:

- "name": net client name (json-string)
- "promiscuous": promiscuous mode is enabled (json-bool)
- "multicast": multicast receive state (one of 'normal', 'none', 'all')
- "unicast": unicast receive state  (one of 'normal', 'none', 'all')
- "broadcast-allowed": allow to receive broadcast (json-bool)
- "multicast-overflow": multicast table is overflowed (json-bool)
- "unicast-overflow": unicast table is overflowed (json-bool)
- "main-mac": main macaddr string (json-string)
- "vlan-table": a json-array of active vlan id
- "unicast-table": a json-array of unicast macaddr string
- "multicast-table": a json-array of multicast macaddr string

Example:

-> { "execute": "query-rx-filter", "arguments": { "name": "vnet0" } }
<- { "return": [
        {
            "promiscuous": true,
            "name": "vnet0",
            "main-mac": "52:54:00:12:34:56",
            "unicast": "normal",
            "vlan-table": [
                4,
                0
            ],
            "unicast-table": [
            ],
            "multicast": "normal",
            "multicast-overflow": false,
            "unicast-overflow": false,
            "multicast-table": [
                "01:00:5e:00:00:01",
                "33:33:00:00:00:01",
                "33:33:ff:12:34:56"
            ],
            "broadcast-allowed": false
        }
      ]
   }
