To support OSs not yet ported to Xen (e.g. Windows) requires either
Intel's VT (Vanderpool) or AMD's Pacifica technology. Not too many of
those around right now, but that will change soon. Wikipedia says it's
present in "Pentium 4 6x2, Pentium D 9xx, Xeon 7xxx and Core Duo
processors, though in the latter case it is sometimes disabled in the BIOS."

cat /proc/cpuinfo | grep vt

OSs ported to Xen (Linux, NetBSD) can run on existing i386 hardware via
paravirtualization. I've used it briefly on FC5 hosting FC5.
