You forgot to give a link (http://www.vmware.com/pdf/asplos235_adams.pdf)
to the paper and the fact that it is three years old.

So the updated story, in a nutshell, is that the first-generation HW
virtualisation (which was state of the art in 2006) is generally slower
than their binary translation technique. Second-generation (EPT, RVI)
features on the other hand do improve performance, are often used by
default, and even a requirement for some VM configurations. Details:
