PCI/GPU Passthrough on Proxmox VE 8: Installation and configuration — by asded on Proxmox Forum

advancedforumLink only (©)Proxmox VE 8

A community tutorial covering BIOS settings, GRUB or systemd-boot IOMMU parameters, VFIO modules, binding a GPU by PCI ID and verifying with dmesg and lspci. Replies note that amd_iommu=on is redundant on AMD and vfio_virqfd is no longer needed on PVE 8, so check the thread for corrections.

Quick steps

  1. Enable VT-d/SVM in BIOS and check whether GRUB or systemd-boot is used
  2. Add IOMMU kernel parameters and VFIO modules, update initramfs, reboot
  3. Bind the GPU IDs to vfio-pci in /etc/modprobe.d/vfio.conf and confirm with lspci -nnk
