Are you referring to this[1] bug? So far, this bug has been categorized as just a UI bug, so Harvester's guests should still be virtualized with hardware acceleration on AMD bare metal or nested. [1] https://github.com/harvester/harvester/issues/3900

No. In AMD Dell BIOS, "Virtualization Technology" is Enabled already. And

grep svm /proc/cpuinfo

on hypervisor Dell host is showing many entries. Also

/sys/module/kvm_amd/parameters/nested

is with value

1

already. But on its new VMs,

grep svm /proc/cpuinfo

gives me nothing. Isn't this buggy?

I don't have an AMD box to test with, but does your hypervisor have this parameter:

/sys/module/kvm_amd/parameters/nested

I'm running a Harvester cluster on Asus PN50s, which are AMD Ryzen 7 4700U. I've run Harvester in VMs on that cluster too.
