Re: Virtio graphics don't work with NVIDIA proprietary driver

You cannot really have 3D acceleration on a virtual spice display. If you connect a monitor to your passthrough card, you'll get 3d accelerated graphics on it. One feature that seems to be missing from qemu is some way to mirror that GPU screen into the VMM console.

I have virt-manager on a Fedora Workstation 26 host.

I have set up a Virtual Machine with Windows 11 Educational.

I have a Spice display server, with Listen Type set to “None”, OpenGL set on with my NVIDIA graphics card.

I use proprietary NVIDIA drivers.

I also use virtio video with 3D acceleration set on.

However when I start the virtual machine, I get the following error:

How can I have my VM work with 3D acceleration on NVIDIA graphics card?

Best,
