Thanks Robert. It should be http://docs.openstack.org/havana/install-guide/install/apt/content/install-neutron.install-plug-in.ovs.gre.html So I can install neutron in my controller or compute node with 2 nics, and configure as the document describes except that need to replace the DATA_INTERFACE_IP with the internal subnet nic's IP as below? [ovs] tenant_network_type = gre tunnel_id_ranges = 1:1000 enable_tunneling = True integration_bridge = br-int tunnel_bridge = br-tun local_ip = DATA_INTERFACE_IP Thanks.
