Loading the kvm-amd module should be done automatically by
kvm/qemu, and it will tell you if it can't.

Normally Intel has a BIOS setting to turn it on/off, and AMD
machines just leave it on all the time. Since there is no
performance hit to turn it off, I am irked at Intel.

I am also irked at HP, who has managed to include such a BIOS
setting for AMD machines and defaults it to off. None of my
other AMD motherboards requires such a change.
