Enable KVM on Gigabyte X570 Motherboards

On some AMD Ryzen X570 (Gigabyte) motherboards, virtualization is disabled in the UEFI firmware (BIOS). If are having trouble running qemu or virtualbox, the kvm module is loaded, and lscpu indicates that the CPU supports KVM, go into the BIOS, Tweaker menu tab (advanced mode), find "Advanced CPU settings" and enable "SVM mode".

On some boards, you can find the KVM settings under "Advanced CPU Core Settings" option group, under M.I.T tab - "Advanced Frequency Settings" option group - frequency settings - CPU core settings.
