Version-Release number of selected component (if applicable):
rhevm-3.2.0-5.el6ev.noarch

How reproducible:
100%

Steps to Reproduce:
1.Create VM with 1 nic and start the VM
2.while the VM is up hot-unplug the nic and change the MAC address (one operation)> should fail > Bug 904840
3.Create a new nic with the same MAC address from step 2.
  
Actual results:
Fail with error MAC Address is already in use.

Expected results:
MAC address should be free and can add to new nic.

This scenario is really a corner case on other bugs since there is no reason to fix it, what should be fixed are the scenarios that caused MAC change to fail.
