With a little perl scripting, it wouldn't be hard to write a load

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.
