I would like to add a few more comments on this part..

One thing you have to remember is that with virtulization any piece of
hardware that needs to be used by both host and guest has to be in
some way emulated. So with virtulization you have an emulated
processor (even with the extra helper instructions), emulated memory,
emulated motherboard / bios/interrupts/clock, emulated hard drive
controllers, emulated hard drives, emulated keyboard, emulated mouse,
emulated sound card, emulated video card, emulated usb... These
emulations generally require 2 device drivers (one on the host and 1
on the guest) and a layer in between to translate. This emulation eats
cpu and io performance.
