For all you super technical people out there looking for a great explanation of how the Xen Hypervisor works and was designed, I highly recommend getting the following book: The Definitive Guide to the Xen Hypervisor by David Chisnall. I bought it from Amazon at http://www.amazon.com/Definitive-Hypervisor-Prentice-Software-Development/dp/013234971X/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1199980643&sr=8-1

I get no kickback on the order but thought people who wanted to really understand the Xen Hypervisor and how it works would like the information.
