Configuring the bridges

To configure a bridge with Open vSwitch, use the Open vSwitch utility ovs-vsctl. Create the bridge br-eth2 on compute02, compute03, and snat01, as follows:

    # ovs-vsctl add-br br-eth2

Use the ovs-vsctl add-port command to add physical interface eth2 to the bridge like so:

    # ovs-vsctl add-port br-eth2 eth2

The configuration of the bridge should persist reboots. However, the bridge interface can also be configured in /etc/network/interfaces if necessary using the following syntax:

auto br-eth2 allow-ovs br-eth2 iface br-eth2 inet manual     ovs_type OVSBridge    ovs_port seth2allow-br-eth2 eth2 iface eth2 inet manual     ovs_bridge br-eth2     ovs_type OVSPort 

Please note that the physical switch port connected to eth2 must support ...
