How did you search for the MAC?
Perhaps there's some bug hidden here that the MAC is listed in the DB but you can't see it.

In such a case you can try to query the DB directly with this SQL:
select * from vm_interface where mac_addr = 'YOUR_MAC';

Of course you need to put your MAC, and then see if it returns anything.

In respect to the situation, I have started a thread on engine-devel at ovirt.org for the devs to decide how to handle this situation in a more graceful way: http://lists.ovirt.org/pipermail/engine-devel/2013-February/003665.html
