---------------
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 } }
GUEST_PANICKED
--------------
Emitted when guest OS panic is detected.
Data:
- "action": Action that has been taken (json-string, currently always "pause").
Example:
{ "event": "GUEST_PANICKED",
"data": { "action": "pause" } }
NIC_RX_FILTER_CHANGED
---------------------
The event is emitted once until the query command is executed,
the first event will always be emitted.
Data:
- "name": net client name (json-string)
- "path": device path (json-string)
{ "event": "NIC_RX_FILTER_CHANGED",
"data": { "name": "vnet0",
"path": "/machine/peripheral/vnet0/virtio-backend" },
"timestamp": { "seconds": 1368697518, "microseconds": 326866 } }
}
QUORUM_FAILURE
--------------
Emitted by the Quorum block driver if it fails to establish a quorum.
Data:
- "reference": device name if defined else node name.
- "sector-num": Number of the first sector of the failed read operation.
- "sector-count": Failed read operation sector count.
Example:
{ "event": "QUORUM_FAILURE",
"data": { "reference": "usr1", "sector-num": 345435, "sector-count": 5 },
"timestamp": { "seconds": 1344522075, "microseconds": 745528 } }
QUORUM_REPORT_BAD
-----------------
Emitted to report a corruption of a Quorum file.
Data:
- "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 the
block layer reported an error and clients should not try to
interpret the error string.
- "node-name": The graph node name of the block driver state.
- "sector-num": Number of the first sector of the failed read operation.
- "sector-count": Failed read operation sector count.
Example:
{ "event": "QUORUM_REPORT_BAD",
"data": { "node-name": "1.raw", "sector-num": 345435, "sector-count": 5 },
"timestamp": { "seconds": 1344522075, "microseconds": 745528 } }

- "family": address family (json-string, "ipv4" or "ipv6")
- "client": Client information (json-object)
- "host": IP address (json-string)
- "port": port number (json-string)
- "family": address family (json-string, "ipv4" or "ipv6")
Example:

- "family": address family (json-string, "ipv4" or "ipv6")
- "connection-id": spice connection id. All channels with the same id
