Johnson D

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 = gre
tunnel_id_ranges = 1:1000
enable_tunneling = True
local_ip = 192.168.100.1
tunnel_bridge = br-tun

Create and configure bridges on all machines running Quantum and OpenvSwitch components

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.
