Comment 9 for bug 1376596

Clearly was not deprecated since neutron does not provide the same functionality (FlatDHCP for example) and there is not a migration path yet...

Concerning the bug, I think we could improve the situation in two ways:

1) Not setting the flat_interface on nova.conf should not bridge the interfaces (right now forces 'lo');
2) if NOT, check if the interface is 'lo' like here http://sethanil.blogspot.ch/2014/11/openstack-nova-compute-fails-to-start.html and not bridge the interfaces.

The origin of this bug is due to the impossibility to add loopback to the bridge on rhel 7 (reference: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=1153079)
