Ryzen BIOS options and KVM virtualization

I had some troubles when trying to use KVM virtualization on the somewhat new Ryzen platform.

You must enable IOMMU and SVM both. This exact configuration varies depending on your motherboard manufacturer and BIOS, but you should be able to find these settings somewhere in there.

Otherwise you’ll end up with errors relating to being unable to find KVM modules in your kernel, modprobe reporting kvm_amd not found, and dmesg talking about KVM being bios-restricted.

Good luck!
