Isn't this what I proposed:
	Maybe we can
	start VF with a temporary MAC, then change it to a final one when guest
	tries to use it. It will work but we run into fact that MACs are
	currently programmed by mgmnt - in many setups qemu does not have the
	rights to do it.

?

If yes I don't see a problem with the interface design, even though
implementation wise it's more work as it will have to include management
changes.
