Description of problem:
The migration tests on jenkins first migrates the guests to file (offline migration) and then wakes them up couple of times. Then comes the online migration tests -- live migrations between hosts. 

The live migrations sometimes fails due to the machine doesn't succeed to get the UP status.

Sometimes it also fails to migrate for some reason and wakes up on the same host as it was before.

Digging trough the logs, I've seen many of messages like:

That's ugly, but that's only log noise.
