Hardware requirements for running unmodified guests

Marko Asplund
hi

We're planning on purchasing a new AMD64 or EM64T based server in the
near future. It would be very nice if we would be able to use server
virtualization with Xen on the new machine. We'd like to run unmodified
guest operating system instances on the server. I'm new to Xen but if
I've understood correctly you can run unmodified guest operating system
instances if the hardware supports certain virtualization techniques.

What are the things I should look for in the server specification sheets
to make sure that the server hardware supports these virtualization
techniques? Which components are required to have VT support in addition
to the CPU? Which CPUs currently support VT?

How does running unmodified guests with Xen compare to using VMware? Can
I expect better performance with VT + Xen?
