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

+MIGRATION_CANCELED
+------------------
+
+Emitted when migration is canceled.  This is emitted in the source.
+Target will emit MIGRATION_FAILED (no way to differentiate a FAILED
+and CANCELED migration for target).
+
+Data: None
+
+Example:
+
+{ "event": "MIGRATION_CANCELED",
+    "timestamp": {"seconds": 1274687575, "microseconds": 592483} }
+
+MIGRATION_ENDED
+---------------
+
+Emitted when migration ends (both in source and target)
+
+Data: None
+
+Example:
+
+{ "event": "MIGRATION_ENDED",
+    "timestamp": {"seconds": 1274687575, "microseconds": 592483} }
+
+MIGRATION_FAILED
+----------------
+
+Emitted when migration fails (both is source and target).  Notice
+that this event will be changed for 0.14 when we have infrastructure
+to emit a QError when things fail.
+
+Data: None
+
+Example:
+
+{ "event": "MIGRATION_FAILED",
+    "timestamp": {"seconds": 1274687575, "microseconds": 592483} }
+
+MIGRATION_STARTED
+-----------------
+
+Emitted when migration starts (both in source and target).
+
+Data: None
+
+Example:
+
+{ "event": "MIGRATION_STARTED",
+    "timestamp": {"seconds": 1274687575, "microseconds": 592483} }
