Tesla P40 driver installation on Ubuntu 24.04 virtualized with Proxmox 8.2.4

I have a dell poweredge r730 with a Proxmox installation in which i virtualized ubuntu 24.04. I installed the drivers by downloading them from the nvidia drivers download page, specifically: nvidia-driver-local-repo-ubuntu2404-550.90.07_1.0-1_amd64.deb. But when i run nvidia-smi i get:

No devices were found

running lspci i corrently can see my gpu:

01:00.0 3D controller: NVIDIA Corporation GP102GL [Tesla P40] (rev a1)

and something is wrong in dmesg | grep -i nvidia:
