How to enable Virtualization on Fatal1ty X470?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   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?

	https://www.quora.com/Why-is-it-needed-to-enable-virtualization-from-BIOS-in-order-to-emulate-OSes I would guess mostly because of security reasons
