Virtualization Extensions are unavailable

(1/3) > >>

Hi,

I've got my new Blackbird and installed Fedora 32 on it, KVM and GNOME BOXES. When I try to create VMs I get the following error messages: "Virtualization extensions are unavailable on your system. Check your BIOS settings to enable them".

I've tried all options on PetitBoot menu but could not find how to enable virtualization extensions.

Anyone had this issue? Any help is welcome.

Thanks,

Virtualization is always enabled.  Are you seeing that error from a specific piece of software or from the direct QEMU command line?

I saw that error from the GNOME Boxes. If I run the command egrep '^flags.*(vmx|svm)' /proc/cpuinfo I also get no response. Any idea?

Sounds like a bug in GNOME Boxes, which to be honest isn't an application I'd heard of before today.  Can you try a different application like virt-manager?  You might want to file a bug report against GNOME Boxes as well.

Most architectures don't report their hardware support flags in /proc/cpuinfo, that's pretty much an x86-only thing.  POWER has full virtualization support in Linux, it's not something that can be turned off unless you build a kernel without the needed support.  If you look for /dev/kvm, you should see that it exists, that's all you need.

Hi,

Thanks. I've succeeded to create a VM using virt-manager.

But the path /dev/kvm does not exist in my file system. Does that mean that I'm running software virtualization and not hardware virt?

Regards
