This is nasty -- the domain is probably crashing during the migrate. We
have never seen this failure mode on 2.0.7, even after many thousands of
migrates.

Have you compiled your own kernel or are you using one of ours? (I
presume 2.6.11 ?)

What are you running in the guest?

What does 'xm dmesg' show?
