michal: How many virtual CPU's do you have for your VM? Through experimentation, I've just discovered that I can get good performance with VT-x enabled if I set the number of CPU's to 1 on my Core 2 Duo machine (P8700). I was able to set it to 2 CPU's under Jaunty without a problem -- but the performance with it set to 1 CPU in Karmic is excellent, so I don't know if this is a bug or a feature.
