=== Events ===
Events are defined with the keyword 'event'. When 'data' is also specified,
additional info will be carried on. Finally there will be C API generated
in qapi-event.h; when called by QEMU code, a message with timestamp will
be emitted on the wire. If timestamp is -1, it means failure to retrieve host
time.
An example event is:
{ 'event': 'EVENT_C',
'data': { '*a': 'int', 'b': 'str' } }
Resulting in this JSON object:
{ "event": "EVENT_C",
"data": { "b": "test string" },

QEMU Machine Protocol Events
============================
ACPI_DEVICE_OST
---------------
Emitted when guest executes ACPI _OST method.
- data: ACPIOSTInfo type as described in qapi-schema.json
{ "event": "ACPI_DEVICE_OST",
"data": { "device": "d1", "slot": "0", "slot-type": "DIMM", "source": 1, "status": 0 } }
BALLOON_CHANGE
--------------
Emitted when the guest changes the actual BALLOON level. This
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 },
"timestamp": { "seconds": 1267020223, "microseconds": 435656 } }
BLOCK_IMAGE_CORRUPTED
---------------------
Emitted when a disk image is being marked corrupt.
Data:
- "device": Device name (json-string)
- "msg": Informative message (e.g., reason for the corruption) (json-string)
- "offset": If the corruption resulted from an image access, this is the access
offset into the image (json-int)
- "size": If the corruption resulted from an image access, this is the access
size (json-int)
Example:
{ "event": "BLOCK_IMAGE_CORRUPTED",
"data": { "device": "ide0-hd0",
"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)
