[Linux-cluster] XEN VM Cluster



I'm trying to do a two node cluster.
I want start a virtual machine at vserver1 and reallocate it to vserver2 if node 1 stop.
The VM is installed in a shared HP storage.
This access is made with two Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter.
If I start it manually which xm create its ok in both servers.
The partition is a LVM in /dev/VG2/LV01.
I install virtual machine directly in this partition.
The names vserver1 e vserv2 are in the /etc/hosts.
The cluster start but vserver2 join and after appear "Member Left".

I think that my problem is in fence device.
I don't have any equipament.
I have only the servers, storage, NICs and Emulex.

I didn't find any manual for this situation.
