Version-Release number of selected component (if applicable):
3.5.3-0.2.el6ev

How reproducible:
100

Steps to Reproduce:
1. UCS setup with port profile configured.
Run sudo engine-config -s CustomDeviceProperties=
 '{type=interface;prop={vmfex=^[a-zA-Z0-9_.-]{2,32}$}}' on engine and 'yum install vdsm-hook-vmfex-dev' on servers.
2. In rhev-M Configure vNIC profile with vmfex=>UCS port profile 
and assign the profile to VM
3. Run VM using vmfex profile and try to migrate to second host.

Actual results:
Migration failed with hook error on destination

Expected results:
Migration should succeed.
