GPU sharing in Proxmox

[aldomoro]

Hi

If I insert two dedicated GPUs (e.g. some powerfull Nvidia model) to the Proxmox server, is it possible to manage usage these GPUs?
For instance, can I dedicated sources of one GPU to VM1 and VM2 (50%+50%) and sources of the second GPU to VM3 and VM4 (70%+30%)?
VM would have Windows 11.

My goal is to create several 3D virtual desktops for Autocad work.

Thank you

Only with vGPU on Nvidia cards and this requires expensive enterprise models and a vGPU license (if you don't want it to be hacky and legal).
Maybe the new Intel Enterprise GPUs are an option. As far as I understand its SR-IOV doesn't require perpetual license fees.

Thanks. And is it possible to dedicate one GPU to one VM to avoid vGPU solution?

Yes, but for 4 VMs you then need a proper Workstation/Server platform with lots of PCIe labes for those 4 GPUs.
