                   QEMU Monitor Protocol Events
                   ============================

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):
    "ignore": error has been ignored
    "report": error has been reported to the device
    "stop": error caused VM to be stopped

Example:

{ "event": "BLOCK_IO_ERROR",
    "data": { "device": "ide0-hd1",
              "operation": "write",
              "action": "stop" },
    "timestamp": { "seconds": 1265044230, "microseconds": 450486 } }

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

RESET
-----

Emitted when the Virtual Machine is reseted.

Data: None.

Example:

{ "event": "RESET",
    "timestamp": { "seconds": 1267041653, "microseconds": 9518 } }

Data: None.

Example:

{ "event": "RESUME",
    "timestamp": { "seconds": 1271770767, "microseconds": 582542 } }

RTC_CHANGE
----------

Emitted when the guest changes the RTC time.

Data:

- "offset": delta against the host UTC in seconds (json-number)

Example:

{ "event": "RTC_CHANGE",

    "timestamp": { "seconds": 1267020223, "microseconds": 435656 } }

{ "event": "SHUTDOWN",
    "timestamp": { "seconds": 1267040730, "microseconds": 682951 } }

Note: If the command-line option "-no-shutdown" has been specified, a STOP
event will eventually follow the SHUTDOWN event.
