The document discusses PCI passthrough on a Proxmox virtualization server. It lists the hardware including an i7 CPU, MSI motherboard and various Nvidia and AMD graphics cards. Configuration files for PCI passthrough are modified and an RX 480 card is passed through successfully while GTX 1080 and 770 cards fail passthrough. Future work is planned to try patch ROMs and other cards. References on GPU passthrough techniques are provided.
