Here in Grid-Ireland / TCD we've been running grid service nodes on Xen
VMs for about five years now. Guests and Hosts are installed and
configured using Quattor. (Before that we used User-mode Linux and LCFGng!)
The assignment of VMs to hosts is static: we don't use a shared image
storage pool.
We also have a replication mechanism for failover between VM hosts.
Kind regards,
David
