Hello, I am posting today because I am having troubles with setting up an “optimized” virtual machine on my PC. I have my system info, the error, and the videos I watched below. What I am currently stuck on is trying to change some of the VM settings, like the video model and a few others that I can’t remember RN.

Here are the tutorial videos that I watched:

You should first… a bios update ?

After bios update pls think on right settings. (fastboot, secureboot, etc)

then perhaps update the system or ?

and after this → reboot and take a look if all correct installed for kvm/qemu.
That’s simple if you use Garuda Assistent and / or use the konsole to look if all is installed with pacman -Qs qemu
Activate (if not) the stuff about “virtualization” (virt-manager libvirtd enabled + user in libvirt)
Reboot → start the virtual manager and start a new vm with your preferred *.iso.
The how-to config qemu vm is then “easy.”
Your system amd ↔ amd. (means opengl is possible)
Example garuda iso but it’s not optimized for a vm.
Right size for image (a garuda iso needs 31gb → enough memory + cpu →
Display spice server → listen “no” → button opengl “active” → Video model “virtio” + button 3d enabled. All other leave at the moment " default." Save and start the vm.
The vm should run with no errors then.

I think going to Garuda assistant and enabling virtual manager is what I needed to do to fix the issue, but I’m not 100% sure…

I did not however update my bios, so that definitely wasn’t the issue.

But you should do this anyway. At least one of them contains security updates.

Update AMD AM4 AGESA Combo V2 PI 1.2.0.Cc to patch SMM Lock Bypass security issue.

Oh, alright. I will look into how to do it then since it does have a security patch.

When you do update your bios so make sure to write down what you have changed so far as it will clear the settings.
