I don't really know what could be happening with those machines. If this problem only happens on > 10.04 VMs then it looks like a change in the distribution that makes the VM behave like that. I would also try stop/resume (that does the same steps as migration) and check if the same problem arises. You can also do the stop/resume test with the scheduler stopped and use onevm deploy to schedule the VM to the same host, this way we can check if the problem is related to some configuration changes between physical nodes.
