I'd say if  we have more than 1 NIC in a VM, we have to fixate name <-> mac 
regardless of possible conflict (if there is a conflict, we have to re-generate 
mac addresses - but it's a bit different story). To be honest, I don't 
understand the reason of ignoring NIC name persistence in VM, but those line 
were intentionally added - so, the reason apparently exists. It goads my 
curiosity :)

Yes, it's exactly "75-persistent-net-generator.rules" file. Done as a patch 
because we cannot remove the rules file.
