Created attachment 1327474 [details] engine log Description of problem: MAC address can be used after vNIC unplug - NO duplication is allowed in the cluster. It is possible to assign a MAC address after unplugging the vNIC from the VM(no duplication is allowed in the cluster), although it should be considered as in use. The MAC address should be released only on vNIC remove. This is a new regression. Version-Release number of selected component (if applicable): ovirt-engine-4.2.0-0.0.master.20170917124606.gita804ef7.el7.centos.noarch How reproducible: 100 Steps to Reproduce: 1. RUN VM with 1 vNIC in cluster with no duplication allowed 2. Unplug the vNIC 3. Assign the VM's MAC address to another VM Actual results: It is possible to assign the MAC address to another VM. Expected results: Should fail with MAC address already in use error.
