Vlan mode in OpenVswitch on OpenStack Grizzly

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.
