Hi Trevor, Reply is a bit late, perhaps you found a solution already. I had the same problem and found an article about it and a workaround: http://docs.cloudstack.org/Knowledge_Base/20__KVM_hosts_and_they_can%27t_connect_after_a_cloud-management_restart
Hope that helps.

After that, all of my hosts say they are in the "Connecting" state, and I will not leave that state. I have put them into maintenance…..and then back out…no dice. I have tried rebooting hosts, no dice. Cannot force-reconnect a host as I am getting an error "Command failed due to Internal Server Error" Running 4.0.0-incubating.20121024195401 I have 3 primary storage volumes: NFS RBD Storage Share Mountpoint To get the hosts to respond again, I had to delete them and re-add them. This isn't a solution, as it would wipe out all of my VMs attached to local storage….not good.
