I suspect oVirt uses the IEEE [1] space allocated to Qumranet and that space is relatively small. There were previous discussions on the list regarding the probability of
collisions/exhaustion, IIRC. In any case, you want re-use to prevent the possibility of exhaustion and because a program shouldn't just go randomly creating addresses from any available OUI block.
