Hi Tom,

Thank you for the input. Let's forget about XEN for a moment, I was
actually looking at setting up a cluster which has fail-over & load
balancing capabilities, regardless of what runs on it. If XEN
enterprise is the only option,then I'm not going to bother. I don't
see why I need to pay for a tool which has a helpdesk and
"professional technicians standing by" to help me when I get stuck, if
XEN can do the same.
