The following procedure is tested on OpenStack grizzly version running on Ubuntu 12.04
Before creation of any networks in the OpenStack setup, add the following lines in /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini under “[OVS]” section on all the machines of an OpenStack setup running Open vSwitch and Open vSwitch agents.
tenant_network_type=vlan bridge_mappings=physnet1:br-eth1 enable_tunneling=False network_vlan_ranges=physnet1:1000-2000 integration_bridge=br-int
Create and configure bridges on all machines running Quantum and OpenvSwitch components
ovs-vsctl add-br br-eth1 ovs-vsctl add-port br-eth1 eth1 ovs-vsctl add-br br-int
Restart appropriate services
/etc/init.d/openvswitch-switch restart /etc/init.d/quantum-plugin-openvswitch-agent restart
If Quantum server is running in the machine. Restart it.
/etc/init.d/quantum-server restart
Now create networks as per the requirement, using Nova commands or the OpenStack Dashboard.
