After installing openvswitch plugin on the controller node, I am creating the external and internal bridges. br-ex and br-int. Then I am removing the external ip of controller network interface and configured it to run in promiscous mode. I am reassigning the external IP to the br-ex bridge by creating ifcfg-br-ex file. But the controller is losing its external network connectivity because I dont see the external IP asigned to the br-ex. How to regain external network connectivity on the controller again ?

Make sure that you add the interface that previously had the external IP to the bridge.

For example, if eth0 previously had the external IP:

ovs-vsctl add-port br-ex eth0

This will bridge br-ex and eth0 together. Since br-ex now has your external IP, traffic will flow through br-ex to eth0 to the wire and back.

Hope that helps,
