Troubles or Misunderstanding?

Hello to all,
I go straight to my problem, my nvidia card works fine with proprietary drivers on my archlinux distro and if it’s just a basic usage it’s ok.
For virtualization purpose I’ve installed all the package to work with qemu-kvm and in “graphics” section I’ve selected virtio driver with 3d accel but the machine doesn’t start, it returns me “’/devdri’ no such file or directory”
I’m pretty sure I’ve loaded all the necessary.
If I look to loaded modules I cannot find nvidia_drm even I specified into /etc/mkinitcpio.conf.
The question is: did I get wrong the nvidia-drm usage?
Thanks
