Using answer field as a comment

Per ovs-vsctl report :-
eth0 is OVS port of OVS bridge br-ex
However per `ifconfig` report :-
eth0 doesn't show up at all
br-ex doesn't have IP

Please run :-

neutron router-port-list  demo-router

Next :-

1. If eth0 is OVS port of br-ex, then IP from eth0 should be assigned to br-ex. eth0 is not supposed to have IP at all
2. Please, run `neutron port-show 0cda519a-a010-4fd2-81bd-f69c3a84c2b8`

Thanks for helping, it is still not working after I clear the ipaddress on eth0. can you email me "answer" instead of going through here. I am not good at using this. alex.leung@jpl.nasa.gov

What do I have to set on the /etc/network/interfaces file?

aleungops ( 2015-10-06 14:52:15 -0500 )edit

That is correct.
