Migration appears to be broken for me.  It's not caused by this series
but I'm surprised you didn't encounter it.  Maybe it's my kernel version?

My suspicion is that the cause of this is:

Can you prove your suspicion a bit by retrying with -cpu ...,-kvmclock?
Is your guest using kvmclock? Are you migrating from old to new or
between new versions?

Heh, it turns out I was migrating from KVM to TCG :-)

This changeset "breaks" that but I don't think I'd count this as a
supported use-case so I don't count it as a regression.

So ignore the noise here.

I would say it now breaks earlier and less subtly. :)

GPE is broken.  see Isazu & Avi comments.  It worked for me with Sunday

Later, Juan.
