Hello, we are currently discussing XEN with clustering support. There came some questions we are not sure what the answer is. Perhaps you can help ;-) . Background is: We are discussing a group of XEN Dom0 Hosts sharing all devices and files via GFS. They themselves again host a couple of virtually redhat-clustered DomU Hosts with or without gfs. 1. Live Migration of cluster DomU nodes: When I live migrate a virtual DomU clusternode to another DOM0 XEN Host the migration works ;-) , but the virtual clusternode is thrown out of the cluster. Is this a "works as designed"? I think the problem are the heartbeats not coming in proper time. Does that lead to the conclusion that one cannot live migrate cluster nodes? 2. Fencing: How about fencing of the virtual Dom-U Clusternodes. You are never sure on which Dom-0 Node runs our Dom-U Clusternode. Is the fencing via fence_xvm[d] supported on such an environment? That means how does a virtual DomU clusternode X running on Dom0 Xen Host x know that if virtual DomU clusternode Y running on Dom0 Xen Host y is running there when it is getting the fence request to fence Host y where it is running?
