In the Gigabyte BIOS you need to activate a series of settings on different sections in order for KVM to be able to use hardware acceleration.
- M.I.T. -> Advanced Frequency Settings -> Advanced CPU Core Settings -> SVM Mode set to Enable
- Chipset -> IOMMU set to Enabled
Save settings and reboot.
Run the KVM check to see if the system is capable or running hardware accelerated virtualisation.
kvm-ok
virt-host-validate
If you still fail the check review your BIOS/motherboard documentation to activate the correct setting.
