Sharing Nvidia Quadro RTX 8000 to Multiple VMs in Proxmox


I have a Nvidia Quadro RTX 8000 48GB Card.
I wanted to use it with proxmox to share the same gpu in upto 4 ubuntu virtual machines using the vGPU Profiles.

I installed the nvidia vGPU driver on proxmox and is working fine (nvidia-smi shows). I download the evaluation vgpu drivers from
The vgpu profiles shows correctly when adding pcie device to VM.

Also I was able to install the guest drivers on ubuntu vm, the installation was complete but when running nvidia-smi on guest ubuntu vm it is giving error communicating with device.

Has anybody got this setup or similar working.
If anybody can help me on this.
Is this setup even possible with Proxmox?

Nvidia officially supports this but with vmware vsphere or citrix hypervisor, i am not familiar with these hypervisors so wanted to give it a try with proxmox.

My config:
Dell R750
196 GB RAM
Nvidia Quadro RTX 8000 48 GB - Slot 2
Nvidia A100 80 GB - Slot 1
Latest Proxmox with Latest Kernel

Thanks in advance.
