I'm trying to dig into this some on my own (without knowing about
oVirt's internals); can somebody tell me the timeout for the dispatching
of commands to vdsm?  I get different things happening when the engine
thinks a node has "gone away", but they all start with the same
org.ovirt.engine.core.vdsbroker.vdsbroker bit (and have a network
timeout of some type).

I don't see anything in common in any of the logs at the time of the
error, so I'm trying to roll back to when the request was sent (but I
don't know how long it took for the engine to time out before the error
was logged).
