Version-Release number of selected component (if applicable):

How reproducible:

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.

Comment 3 Dan Kenigsberg 2015-09-30 06:45:15 UTC
Michelle, as far as I understand, this bug is closed and verified. It would be closed once rhev-3.6.0 is out, and no work is expected on it.
Note that there's a 3.5.4 bug 1226709 which is already made available to customers with rhev-3.5.4.

Which version of Vdsm does the customer have? And hich version of vdsm-hook-vmfex-dev?
