Turns out I spoke too soon. With the patch applied, it boots, but if I
try to do a live migration both the source and destination crash. This
happens for both the master branch as well as the stable-1.4 branch.
The destination doesn't crash, it simply stops because it got an
incomplete migration stream. Thanks for the report, the patch seems
correct so it's worthwhile looking at it more closely.
If I back out the patch, it works fine. If I leave the patch in and
disable kvm acceleration it works fine.
Indeed, non-KVM doesn't use ioeventfd at all.
Did anyone ever figure out why wrapping the whole thing in
memory_region_transaction_begin()/memory_region_transaction_commit()
caused problems?
