============================
|

|
|
DUMP_COMPLETED
|
|
--------------
|
|
|
|
Emitted when the guest has finished one memory dump.
|
|
|
|
Data:
|
|
|
|
- "result": DumpQueryResult type described in qapi-schema.json
|
|
- "error": Error message when dump failed. This is only a
|
|
human-readable string provided when dump failed. It should not be
|
|
parsed in any way (json-string, optional)
|
|
|
|
Example:
|
|
|
|
{ "event": "DUMP_COMPLETED",
|
|
"data": {"result": {"total": 1090650112, "status": "completed",
|
|
"completed": 1090650112} } }
|
|
|
|
MEM_UNPLUG_ERROR
|
|
--------------------
|
|
Emitted when memory hot unplug error occurs.

|
|
|
|
Example:
|
|
|
|
{ "event": "MEM_UNPLUG_ERROR"

|
"data": { "device": "dimm1",

|
|
- "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.
|
|
- "sectors-count": Failed read operation sector count.

|
Example:
|
|
|
|
Read operation:
|
|
{ "event": "QUORUM_REPORT_BAD",

"data": { "node-name": "node0", "sector-num": 345435, "sectors-count": 5,
|
|
"type": "read" },
