Comment 5 for bug 1524395

This is also an issue for Kilo see https://github.com/openstack/openstack-ansible/blob/kilo/playbooks/roles/lxc_container_create/tasks/container_create.yml#L91-L103 when we upgrade from Juno to Kilo. The nic config gets converted from the LXC config file to <nic>.ini and triggers a container restart
