With a little perl scripting, it wouldn't be hard to write a load
balancer for Xen.  You would need to track the CPU utilization on each
dom0, and intelligently balance the domU's across them.  Maybe when I
get some free time in the next few weeks I'll do just that :)

You can use nagios (or something like) to monitor Dom0 and DomU. when you have a performance (or failure)  issue you can move the DomU to other Dom0 (use the external commands in the nagios server).

(if it will be in a mission critical env - you may need an High Availability service for the nagios)

It is not just for load balancing, you can use it for High Availability  of VM's, DRP, BCP etc.

We tested a few configuration in our lab in the last week , looks good.

hi,

There is a reason why VMware ESX costs thousands of dollars per node 
and Xen is free.  Once Xen matures with a nice frontend and load 
balancing, VMWare will something to worry about.
    

these are my thoughts too, but never give up the hope ;-) I had several
talks with other people who looking for virtualization software and they
are although impress from vmware, but the price ... you can buy islands
from these money. So they looking for other software and Xen has nice
things too.
