I have never administered a dom0, so I clearly lack understanding here.
Can you please explain why this needs kernel help at all (maybe again,
I didn't get it earlier)?

It sounds to me like xen would have a config file to fire up the domU,
and there could be an entry saying "this domU will use tap14".
So assumming we know what tap device we want upfront, there is already
a simple API to create it, without renaming it later.

What am I missing?
