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",

- "action": action that has been taken, it's one of the following (json-string):
    "ignore": error has been ignored
    "report": error has been reported to the device
    "stop": error caused VM to be stopped

Example:

Note: If action is "stop", a STOP event will eventually follow the
BLOCK_IO_ERROR event.

BLOCK_JOB_CANCELLED
-------------------

Emitted when a block job has been cancelled.

Data:

- "speed":    Rate limit, bytes per second (json-int)
- "error":    Error message (json-string, optional)
              Only present on failure.  This field contains a human-readable
              error message.  There are no semantics other than that streaming
