Typically that means running as a virtual machine, and the hypervisor owns the non-vm register regions and doesn't pass them to the guest. Since the guest runs under the hypervisor, its view of 'real hardware' is what the hypervisor is exposing to it -- in this case with just the "vm" register region. I'll add further explanation along above lines to the commit message if you're OK with it. Thank you Mikko
