General question about Intel and AMD virtualiztion support in hardware

As far as functionality, I believe they are pretty much equivalent.

If you are buying a desktop and want virtualization, then (the last time
I looked), almost all (if not all) AMD CPUs have hw-virt extensions,
while Intel seems to reserve it for the higher-end (read: more
expensive) CPUs.

KVM is essentially a driver for the hw-virt CPU extensions, so of course
it supports them. :-)  Xen also supports hw-virt I believe.
