NVIDIA driver to use virtio-gl

[gcobr]

Hi, All,

My Proxmox host has an NVIDIA Quadro K2200.
I installed NVIDIA drivers with the intention of using VirGL (virtio-gl) with some of my VMs.
I installed the drivers using the binaries provided by NVIDIA themselves: https://www.nvidia.com/download/driverResults.aspx/223426/en-us/

The download is in fact an executable that compiles and then installs the drivers.
Right at the start, it says it is not compatible with the nuveau driver; hence, I added it to /etc/modprobe.d/blacklist.conf:

blacklist nouveau

After the installation, I have:

# lspci -k

03:00.0 VGA compatible controller: NVIDIA Corporation GM107GL [Quadro K2200] (rev a2)
    Subsystem: NVIDIA Corporation GM107GL [Quadro K2200]
    Kernel driver in use: nvidia
    Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia

But then, when I try to start a VM that uses VirGL, I get:
