Running Linux, it's not possible to use virtualization on the Fatal1ty X470 Gaming K4.
The CPU support is there:
# lscpu | grep Virtualization
Virtualization:      AMD-V

But trying to load the kermel module, one gets this error message:
# modprobe kvm-amd
modprobe: ERROR: could not insert 'kvm_amd': Operation not supported

Normally, this is because of virtualization turned off in the BIOS by some security setting.
What is the BIOS option to turn virtualization on?

Moreover, when I modprobe kvm-amd, such a line is appended to the kernel ring buffer:
[54406.792989] kvm: disabled by bios

In uefi/bios, should be under advanced -> cpu configuration -> SVM. Set from disabled to enable. Also check out the OC Tweaker and enable SMT. 

SVM = Secure Virtual Machine
SMT = Simultaneous Multithreading 

Also which Linux kernel version are you running? I know there's a bug within asrock bios containing agesa pinnacle_pi 1.0.0.4. Upgrading your Linux kernel to 4.18.10+ should resolve any virtualization issues your having if you have AMD SVM enabled.

Got it and it works (kernel is 4.18.10). Thanks a lot!
I'm just wondering why this is turned off by default?
