Hi ALL, There is bug https://bugs.launchpad.net/python-neutronclient/+bug/1232965. When set "firewall_driver = neutron.agent.firewall.NoopFirewallDriver" in /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini , Nova operations (list/show/boot) will fail. due to Nuetron client raises NotFound security_group exception. I submit a patch for Nova to fix nova show/list failure. See https://review.openstack.org/#/c/52597/ My question is , which side (Neutron, NeutronClient ,Nova) should fix this , what's the best solution , current I just catch the exception and return empty list of security_group . Any thoughts ?
