Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux Server release 7.1 (Maipo)

How reproducible:

Steps to Reproduce:
1. Create RHEL 7.1 guest on RHEV
2. Start ovirt-guest-agent on guest

Actual results:
Failure to start with traceback shown above. 

Expected results:
successful agent start

Additional info:
This can be worked around by manually changing the ownership of /dev/vport0p1 to ovirtagent:ovirtagent instead of root:root
