I have a single compute node in a 4 compute node cluster, that when I have vms on that node, I have no network connectivity to the nodes. As soon as I live migrate them off that host to any other host, network connectivty comes right up. Any ideas what I should look for? I've looked through all of the logs and I see this in the neutron logs.

Yes. I just restarted that service and had no change in the issue.
