I encounter PV domain restore failure on r14770. Are you guys aware of this?

Our regression tests ran fine on r14773, and our tests include lots of PV
save/restores.

I have the same problem running r14774. The output of "xm log" is very
similar to the one from Edwin. Additionally "xm dmesg" gives me the
following messages:

Is this a 64MB domain? Have you used the balloon driver in the domain (or xm
mem-set) to change the domain's memory usage after it has been created?

Yes, this is a 64MB domain and I haven't changed the size of memory
after creating it.

I can repro this on unstable tip. I'll look into it.
