The next step after checking whether virtualization is possible and enabled would be checking whether the modules are all loaded.
Link goes to the kvm Arch wiki.
still same after manually loading the modules using modprobe LC_ALL=C lscpu | grep Virtualization outputs AMD-V, so i’m guessing that means that it is enabled.
In that case I can just say I don’t know.
I’d suspect Bios/Uefi settings and check those.
The wiki says it needs to be there.
For me, the corresponding module is loaded (I have an Intel machine).
Maybe it is the order the modules are loaded in - this one should probably be loaded first.
Maybe your processor is still not fully supported by the kernel you are using (5.10).
I’m speculating here.
