After I change the user to be administrator, I can get my neutron agents to list as the following: But, I still can not ping other VM from a VM. What can be wrong? Thanks for the help.

I typed "neutron agent-list" in my control and neutron nodes, but nothing returns: What does that mean? root@mussdhux23:/home/stack/Openstack# neutron agent-list root@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.

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.
