Anyone happen to know if this passes cleanly through AMD-V? There are a few really cool debugging facilities on modern x86 processors (e.g. branch-wise versus instruction-wise stepping) that aren't handled in any VM that I know of.

Apparently, Slashdot reader TheRaven64 has read the story. He summarizes it:

Hah, I can't believe woodmann.com is still alive. I used to read through fravia's website's mirror there.

Downvoted? What's wrong with what I said? I appreciated that site.

Because it has nothing to do with the topic, and especially because it doesn't add anything to the discussion.
