Using the Open vSwitch (OVS) plugin in a deployment with multiple hosts requires the using of either tunneling or vlans in order to isolate traffic from multiple networks. Tunneling is easier to deploy, as it does not require configuring VLANs on network switches, so that is what we describe here. More advanced deployment options are described in the ???
Edit
/etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini
to specify the following values:
enable_tunneling=True tenant_network_type=gre tunnel_id_ranges=1:1000 # only if node is running the agent local_ip=<data-net-IP-address-of-node>
After performing that change on the node running quantum-server, restart quantum-server to pick up the new settings.
service quantum-server restart
