See if you can fix it by backing these 3 out to the previous version you
had installed:
[UPGRADE] xen-hypervisor-4.0-amd64 4.0.1-2 -> 4.0.1-4
[UPGRADE] xen-utils-4.0 4.0.1-2 -> 4.0.1-4
[UPGRADE] xenstore-utils 4.0.1-2 -> 4.0.1-4
Post the circumstances/history and a copy of the error log to LKML and
the Xen list. In the mean time, check your filesystems to make sure
none of your VM image files (or anyhting else) didn't get corrupted when
the power died, or as a result of the upgrade. It would probably be a
good idea to check out your hardware as well. Power outages often
included spikes and surges before it completely goes dark. Assuming
you're jacked into a good quality known-to-be-working UPS, damage to the
machine, or storage array, is less likely to be a factor here.
