Hi Matt, Joseph, I have updated the patch per your comments. https://review.openstack.org/633924 Regarding per-host overrides of network information( network -> auto_bridge_add), seems openstack-helm doesn't support it. I prefer to leave auto_bridge_add scope as it is until openstack-helm support per-host overrides of network info. If that, we need add nic to bridge by hand, instead of initContainer. I believe Joseph is trying to find an approach for auto_bridge_add, let's waiting for the result. Thanks, Cheng
