Daniel, could you please remind me the jenkins link? I see something
suspicious on the Vdsm log.
Most notably, Vdsm received SIGTERM. Is this expected and part of the test?

Correct, but IIRC we have a race on startup - that's the reason why MOM
retries to connect. After the new try, MOM seems to behave
correctly:

2017-01-09 16:44:05,672 - mom.RPCServer - INFO - ping()
2017-01-09 16:44:05,673 - mom.RPCServer - INFO - getStatistics()
