Sorry, I’m not sure I follow. So right now, my XCP-NG hypervisor detects 8 GPU cards (Tesla K80). I added a compute offering with passthrough as vgpuType and I was able to successfully create an instance and passthrough 1 gpu. I was able to validate this as well in the guest VM. I was actually hoping that in the createServiceOffering API that there’s a GPU count (just like cpu count) so whenever I use that compute offering it will passthrough that no. of GPU count in the guest VM.
