BLOCK_JOB_COMPLETED ------------------- Emitted when a block job has completed. Data: - "type": Job type ("stream" for image streaming, json-string) - "device": Device name (json-string) - "len": Maximum progress value (json-int) - "offset": Current progress value (json-int) On success this is equal to len. On failure this is less than len. - "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 has failed and clients should not try to interpret the error string. Example: { "event": "BLOCK_JOB_COMPLETED", "data": { "type": "stream", "device": "virtio-disk0", "len": 10737418240, "offset": 10737418240, "speed": 0 }, "timestamp": { "seconds": 1267061043, "microseconds": 959568 } }
