Error is raised on UI, but it doesn't point which interface has the issue. Ideally interface tab should be highlighted with red border

Description of problem:
I was trying to provision a host on rhev instance and I configured couple of virtual interfaces while provisioning the host.

Host provisioning failed with error:

I think there are couple of issues:

1) if nic name is required then that field should marked as mandatory with '*'
2) UI should point the 'interfaces' tab with red border and if possible, also point specific interface where nic name was missing.

Version-Release number of selected component (if applicable):
sat6.2 beta snap7.1

How reproducible:


Steps to Reproduce:
1. create a host on rhev instance
2.
3.

Actual results:
 | OVIRT::OvirtException: NIC name required for add
 | /opt/theforeman/tfm/root/usr/share/gems/gems/rbovirt-0.0.36/lib/rbovirt.rb:210:in `handle_fault'


Expected results:
1) if nic name is required then that field should marked as mandatory with '*'
2) UI should point the 'interfaces' tab with red border and if possible, also point specific interface where nic name was missing.
