Anything in guest dmesg?
No.
No hints in syslog, dmesg...
Can it be that this is more likely to happens on "busy" hosts?
We'll only know once we fix it...

Maybe virtio is racy and a loaded host exposes the race.
I see it happening with virtio on 2.6.29.x guests as well.
So, what would you do if you saw it on your systems as well? ;)
Add some debug routines into virtio_* modules?
