Note: If action is "stop", a STOP event will eventually follow the
BLOCK_IO_ERROR event.
+GUEST_MEDIUM_EJECTED
+--------------------
+
+Emitted when the guest succeeds ejecting a removable medium. If the drive
+has a tray, this is only emitted if the tray opens or closes.
+
+Data:
+
+- "device": device name (json-string)
+- "ejected": true if the tray has been opened or false if it has been closed
+
+Example:
+
+{ "event": "GUEST_MEDIUM_EJECTED",
+ "data": { "device": "ide1-cd1",
+ "ejected": true },
+ "timestamp": { "seconds": 1265044230, "microseconds": 450486 } }
+
+Note: This event does not track all tray changes, as QMP/HMP commands like
+'eject' can also change the tray.
