If you want hardware-accelerated virtualization, you will need to run a 64-bit host if you want to run a 64-bit guest. That much I know. >From my experience on Windows, I can note that you can use hardware-accelerated virtualization of 32-bit guests on both 32-bit and 64-bit hosts. These are just properties of the hardware; there's nothing special about Linux or Windows in this regard. -- :wq
