Hi. I'm trying to add a GPU to Proxmox and I've been following the guide on the wiki. However, it says to add the address of the card in the VM config file. When I click on the VM and go to Add -> PCI Device and click on the drop-down no PCI Devices are listed. Is there a way I can add the GPU so that I can select it from the drop-down instead of adding it through the config file? Thanks!
