Liam and I already understood this by your first posting. Virtualbox
emulates some devices. Take a look at e.g.

  Virtualbox > Settings > System > Tab: Motherboard

you can chose

  Chipset

and you can chose

  Pointing device

Take a look at e.g.

  Virtualbox > Settings > Audio

you can chose an

  Audio controller

The chipset of your motherboard, the pointing device and audio device
could be completely different to the emulated motherboard/machine
devices.
