2025: Proxmox PCIe / GPU Passthrough with NVIDIA — by hoardarous on Proxmox Forum

advancedforumLink only (©)Proxmox VE 8.4.9 (author's setup)

A step-by-step NVIDIA passthrough write-up on Proxmox VE 8.4.9 using Intel VT-d: update BIOS, enable IOMMU in GRUB, create a q35/OVMF VM, blacklist nouveau and nvidia on the host, bind the GPU to vfio and add a hostpci line to the VM. Comments add that vfio_virqfd can be omitted on current releases and that Secure Boot can interfere with guest driver installs.

Quick steps

  1. Add intel_iommu=on to GRUB_CMDLINE_LINUX_DEFAULT, run update-grub and reboot
  2. Create a q35 VM with OVMF BIOS and CPU type host
  3. Bind the GPU in /etc/modprobe.d/vfio.conf and add hostpci0: 01:00,x-vga=on,pcie=1 to the VM config
