Hi Jon,

there are currently a few projects around for this topic.

XenSource is planning to release the XenOptimizer in Q2 2006 AFAIK for this 
purpose, but it is a commercial product

there's an opensource project www.enomalism.com working on a solution, but 
still no beta available. 

OpenQRM / Qluster is an opensource solution which supports Xen-based domUs.
If you are planning to evaluate this, I'd appreciate your comments on it.

Cheers,
Michael
