<div>my 3.2 install seems to be reusing mac address of
formerly-deleted guests. is this the normal behavior, and
or can i turn this off? i would prefer to have a unique mac
address for each new VM created.</div>

I believe re-use is intentional. 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.<br>
