The codenames for the hardware virtualisation projects are Pacifica
for AMD and Vanderpool for Intel.  The official release names are
AMD-V and Intel-VT.  From research I've been doing online, it seems
that (again) the AMD implementation is much better, virtualising a lot
more of the CPU and providing better support for virtual I/O.

The Xen wiki has a nice list of CPU model numbers that have AMD-V and
Intel-VT support:
