Actually I was seeing something similar yesterday and I have seen very
sporadic failures in this area in the past. It seems that in some cases
the VG is not properly set up before we try to use it (perhaps a race with
devicemapper). I wonder if adding some sleeps in
BlockStorageDomain.create() would mask the issue. If so, we need to figure
out where the race is happening and might need to add some polling to make
sure the underlying devices are ready.
