Turning on by default is pointless because guests are not restricted to
running on specific nodes by default. Since manual intervention is required
to achieve that (right now at least) requiring numa=on is not much of a

Integration with xenrt is perhaps possible but we are constrained by machine
resources. Numa=on has been broken for over a month and noone else had yet
complained so it doesn't seem to be a priority for many people.
