Comment 1 for bug 1064643

text from mail archive:

quantum.conf:

core_plugin = quantum.plugins.openvswitch.ovs_quantum_plugin.OVSQuantumPluginV2

ovs_quantum_plugin.ini:
network_vlan_ranges = physnet1
enable_tunneling = False
bridge_mappings = physnet1:br-eth0
To create a shared provider network:

quantum net-create sharednet1 --shared --provider:network_type flat --provider:physical_network physnet1

Before we can run, create br-eth0:
sudo ovs-vsctl add-br br-eth0
sudo ovs-vsctl add-port br-eth0 eth0

we don't need br-ex since we don't use router and floatingip
 and br-tun since we don't use GRE.
