I have a system with 4 A100 40GB cards. I setup the proxmox Ubuntu 22.04 VM with 2 GPU's and I am having trouble detecting the second one. I have checked the IOMMU groups (at least I believe I did.) And they appear to be in different groups. I successfully passed one gpu in and it shows in nvidia-smi. Both GPU's show in lspci on the ubuntu VM but the second GPU is not detected in nvidia-smi. I have attached everything that may be useful below. Nothing crashes and I don't have errors that I can find, it just doesn't show up as a GPU when checking through nvidia-smi.
Any help would be appreciated. I am fairly new to proxmox and had good luck getting the first passthrough and am just struggling on the second. If you need more information let me know.
