Hmm, it's a trove of errors and tracebacks; there's a lot to debug, for
example, here Vdsm was asked to create a 'migration' network on top of
bond0 that was already used by ovirtmgmt. Engine should have blocked
that. Moti?

There are also repeated failed attempts to create a payload disk: did you
notice when they happen? Could it be related to insufficient disk space?
