Hi Juan,

I patched libvirt to be able to consume this event and it all seems to
work fine except for events sent after migrate_cancel command:

{"execute":"migrate_cancel","id":"libvirt-33"}
{"timestamp": {"seconds": 1432899178, "microseconds": 844907}, "event":
"MIGRATION", "data": {"status": "cancelling"}}
{"return": {}, "id": "libvirt-33"}
{"timestamp": {"seconds": 1432899178, "microseconds": 845625}, "event":
"MIGRATION", "data": {"status": "failed"}}
{"timestamp": {"seconds": 1432899178, "microseconds": 846432}, "event":
"MIGRATION", "data": {"status": "cancelled"}}

In other words, the status first changes to "failed" and then it changes
correctly "cancelled". Can you fix this weird behavior in QEMU or do we
have to work around it in libvirt?
