"Verify Connectivity" part of openstack installation - Ubuntu 14.04 not working
We have used 3 nodes (1 controller, 1 network and 1 compute) for installing openstack Juno. Since none of them have more than 1 NICs, we have used virtual interfaces. After creating demo-router, we are not able to ping its port (which by deafult takes up the first ip of Floating range - which it does take in our case).
We are able to ping the interface using - sudo ip netns exec qrouter-1141a29e-5728-4327-81f1-3519617e986e ping 10.1.7.220 from the network node. Following is some important information which might be useful for debugging - all commands are run on controller node:
