It's much simpler with AMD. All AMD AM2 processors, except for Sempron,
support HVM.


Really?
At least with Intel, just knowing that you have a VT CPU doesn't mean
you can actually use that feature and I'd be surprised if that
wouldn't count for AMD. I ran into that trap myself.

I'd guess with AMD, also, the board must support it, must have "good"
acpi tables ( I don't know too much about that, I am kernel hacker,
but i know processes between OS and Hardware fail because of that),
and probably generally be designed quite standard-conform. And I guess
there are quite some that aren't.


(BTW: I have no problem buying amd, just when I needed a VT Notebook,
non amd's where available yet, so I have intel currently)
