I followed the OpenStack icehouse installation guide to successfully install a five node system, one control node, one neutron and three compute nodes. Inside of the instance, I can ping other instances' virtual IP address and outside internet fine. Recently, we decided to move all the nodes to a lab. So, I powered down the five nodes before the move and powered up them afterward. All the physical network connections were exactly the same as they were before the move. But, I can not even ping other instance after the five nodes up again.
I typed "route -n" inside of the instance, no any IP is shown. What's wrong? Please help how I can get the instance networking back.
