Hi Mark and All,
Thank you for the indication to test the neutron agents. I typed "neutron agent-list" in my control and neutron nodes, but nothing returns: What does that mean?
root at mussdhux23:/home/stack/Openstack# neutron agent-list
root at mussdhux20:/home/stack/Openstack# neutron agent-list
I had restarted the neutron services after my neutron node booted up by typing the following commands, but "neutron agent-list" still return nothing.
service neutron-plugin-openvswitch-agent restart
service neutron-l3-agent restart
service neutron-dhcp-agent restart
service neutron-metadata-agent restart
Please help how to start up the neutron agents.
Thank you for the help,
From: Mark Loza [mailto:mloza at morphlabs.com]

I assume you are using neutron instead of nova-network

Did you check if the neutron agents are all alive?

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.
