We have two xen host server in xen server pool. Host1 is the master and host2 is the slave. We restarted the xenhost1 due to server load. After the restart we could not view any VMs or the slave node (host2). Xen center connects only to the host1 with its full memory and CPU. I searched the logs and could not find any UID for VMs only the host UID value is present. Any suggestion will be highly appreciated.
