What processor does hardware virtualization but isn't 64-bit?

If you want a 64-bit guest, I think the host has to support both
hardware virtualization and 64-bit, although the host OS doesn't
technically have to be a 64-bit version.   For example I have run a
64-bit linux guest under 32-bit windows XP with vmware player - and I
think virtualbox would do the same..

Your use case should be fairly common, but you need host support if
you want 64-bit guests.
