Comment 1 lpeer 2012-12-24 12:30:10 UTC 
After talking to Meni adding the missing details -

- step 2 fails because the VM was running and he used hotplug.

BZ 842317 is not about hot plug so I'm not sure this is regression.

Meni - can you please reproduce the scenario from bug 842317 see if this bug is indeed a regression.
Comment 2 Meni Yakove 2012-12-24 12:42:49 UTC 
This BZ in not related to bug 842317. (This BZ related to hot-plug)

Comment 4 Meni Yakove 2013-01-07 09:19:45 UTC 
Verified on rhevm-3.2.0-4.el6ev.noarch.

Can add NIC to vm with same MAC after adding NIC to VM failed.
