I think the question, more specifically, is why use full virutalization (HVM)
instead of paravirtualization? The answers you gave apply to the question,
"Why use virtualization at all?" However, as far as Full vs. Para, the answer
is that Paravirtualization is much more efficient in resource utilization, but
full virtualization allows for running operating systems that are not "aware"
of the fact that they are virtualized or are not compatible with Xen's idea of

Ha! I'd love to see Microsoft provide a Xen-compatible PV kernel, but I'm not
holding my breath - I can see them only doing this in a Hyper-V world, but I
think "enlightened" Windows essentially already does this. Unfortunately it
isn't a true PV kernel, which means you still need HVM support for Xen.
