Proxmox i5-8500 CPU UHD 630 Windows passthrough

ROM file backup:

It works in Legacy mode with the All Gens – No UEFI GOP file.

Requirements

Intel CPU with integrated graphics (2nd generation or newer)
BIOS/UEFI settings:
- UEFI-only boot mode (Disable Legacy/CSM in BIOS/UEFI settings)²
- VGA OpROM set to UEFI (usually disabling Legacy/CSM is enough)
- Enable Intel VT-d (Intel Virtualization for Directed I/O)
- Initial/Primary graphics adapter set to IGD / iGPU / Integrated
Host OS:
- Proxmox VE 9.1 or newer
- Modern Linux distributions (kernel 6.8 or newer)
- IOMMU enabled (enabled by default in Proxmox VE 8.2 and newer)
- Optional: blacklist i915 may be required to enable maximum supported resolution and refresh rate
Guest OS:
- Use OVMF firmware.
- For a headless setup, ensure the guest OS is already installed and has remote access configured (RDP or VNC).

Important

Make sure disable_vga=1 is not set anywhere in /etc/modprobe.d/vfio.conf or in your kernel parameters (/etc/default/grub). If it is, remove it, then run update-grub, update-initramfs -u and reboot.

Important

Meteor Lake, Arrow Lake, Lunar Lake and future Intel iGPU require QEMU 10.1+ (kvm --version)³.

Tip

With Proxmox VE 8.2 and newer, this works without following PCI passthrough guides such as Proxmox PCI Passthrough.

Note

macOS requires additional configuration: macOS_README.md

Setup Instructions

1. ROM File Selection

Choose the appropriate ROM file for your Intel CPU and download/copy it to /usr/share/kvm/

For example, if you have an i7-8700K (Coffee Lake CPU), right-click CFL_CML_GOPv9.1_igd.rom and select “Copy link address”
Then, open the Proxmox VE shell and run the following command to save it as igd.rom in /usr/share/kvm/:

Replace <ROM_URL> with the link you just copied

curl -L <ROM_URL> -o /usr/share/kvm/igd.rom

Note

Use Universal_noGOP_igd.rom as a last resort if other ROMs cause issues. This Universal ROM does not include the Intel GOP driver (UEFI Graphics Output Protocol), display output will only work after the guest VM drivers are fully loaded.

2. VM Configuration

Proxmox VE

Choose a mode: This determines how display outputs (HDMI, eDP, DVI, DisplayPort) behave.

Legacy Mode (Recommended): Display output becomes active as soon as the VM starts.
UPT Mode: Display output becomes active only after the guest OS drivers have loaded.

Legacy Mode

Open Proxmox VE Shell and run:

Replace [VMID] with your real VM ID.

qm set [VMID] --machine pc \
              --vga none \
              --bios ovmf \
              --hostpci0 0000:00:02.0,legacy-igd=1,romfile=igd.rom

Important

Ice Lake, Rocket Lake, Tiger Lake, Alder Lake, and newer CPUs require additional QEMU argument⁵:

qm set [VMID] --args "-set device.hostpci0.x-igd-lpc=on"

Tip

In legacy mode passthrough, these custom args are not needed:

-set device.hostpci0.bus=pci.0 -set device.hostpci0.addr=2.0 -set device.hostpci0.x-igd-opregion=on -set device.hostpci0.x-igd-gms=0x2 -set device.hostpci0.x-vga=on

UPT Mode

Open Proxmox VE Shell and run:

Replace [VMID] with your real VM ID.

qm set [VMID] --bios ovmf \
              --hostpci0 0000:00:02.0,romfile=igd.rom \
              --args "-set device.hostpci0.bus=pci.0 -set device.hostpci0.addr=2.0 -set device.hostpci0.x-igd-opregion=on"

Tip

You should use Universal_noGOP_igd.rom in UPT mode.
