[one-users] problem when migrating ubuntu

[Javier Fontan]

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.
