value is equivalent to the 'actual' field return by the
'query-balloon' command

Data:

- "actual": actual level of the guest memory balloon in bytes (json-number)

Example:

{ "event": "BALLOON_CHANGE",
    "data": { "actual": 944766976 },

Note: this event is rate-limited.

BLOCK_IMAGE_CORRUPTED
---------------------

Emitted when a disk image is being marked corrupt. The image can be
identified by its device or node name. The 'device' field is always
present for compatibility reasons, but it can be empty ("") if the
image does not have a device name associated.

Data:

- "device":    Device name (json-string)
- "node-name": Node name (json-string, optional)
- "msg":       Informative message (e.g., reason for the corruption)
               (json-string)
- "offset":    If the corruption resulted from an image access, this
               is the host's access offset into the image
               (json-int, optional)
- "size":      If the corruption resulted from an image access, this
               is the access size (json-int, optional)

Example:

{ "event": "BLOCK_IMAGE_CORRUPTED",
    "data": { "device": "ide0-hd0", "node-name": "node0",
        "msg": "Prevented active L1 table overwrite", "offset": 196608,
        "size": 65536 },
    "timestamp": { "seconds": 1378126126, "microseconds": 966463 } }

BLOCK_IO_ERROR
--------------

Emitted when a disk I/O error occurs.

Data:

- "device": device name (json-string)
- "operation": I/O operation (json-string, "read" or "write")
- "action": action that has been taken, it's one of the following (json-string):

    "report": error has been reported to the device
    "stop": the VM is going to stop because of the error

Example:

{ "event": "BLOCK_IO_ERROR",
    "data": { "device": "ide0-hd1",

                                     "commit" for block commit)
- "device":   Device name (json-string)
- "len":      Maximum progress value (json-int)
- "offset":   Current progress value (json-int)
              On success this is equal to len.
              On failure this is less than len.
- "speed":    Rate limit, bytes per second (json-int)

Example:

{ "event": "BLOCK_JOB_READY",
    "data": { "device": "drive0", "type": "mirror", "speed": 0,
              "len": 2097152, "offset": 2097152 }
    "timestamp": { "seconds": 1265044230, "microseconds": 450486 } }
