Welcome to our comprehensive guide on how to pass through an Intel integrated GPU to a virtual machine using Proxmox!

In this video, we'll walk you through the step-by-step process of configuring Proxmox to allow direct access of your Intel integrated GPU to a virtual machine, unlocking its full potential for gaming, graphic design, or any other GPU-intensive tasks.

This example was tested with an Intel I5-7600 CPU with a HD Graphics 630 iGPU

Step by Step tasks:

Step 1: Edit GRUB
Execute: nano /etc/default/grub
Change this line from
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on i915.enable_gvt=1 iommu=pt pcie_acs_override=downstream,multifunction video=efifb:off video=vesa:off vfio_iommu_type1.allow_unsafe_interrupts=1 kvm.ignore_msrs=1 modprobe.blacklist=radeon,nouveau,nvidia,nvidiafb,nvidia-gpu"
Save file and exit the text editor

Step 2: Update GRUB
Execute the command: update-grub

Step 3: Edit the module files
Execute: nano /etc/modules
Add these lines:
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
kvmgt
Save file and exit the text editor

Step 4: IOMMU remapping
a) Execute: nano /etc/modprobe.d/iommu_unsafe_interrupts.conf
Add this line:
options vfio_iommu_type1 allow_unsafe_interrupts=1
Save file and exit the text editor
b) Execute: nano /etc/modprobe.d/kvm.conf
Add this line:
options kvm ignore_msrs=1
Save file and exit the text editor

Step 5: Blacklist the GPU drivers
Execute: nano /etc/modprobe.d/blacklist.conf
Add these lines:
blacklist radeon
blacklist nouveau
blacklist nvidia
blacklist nvidiafb
Save file and exit the text editor

Step 6: Adding GPU to VFIO
a) Execute: lspci -v
Look for your GPU and take note of the first set of numbers
b) Execute: lspci -n -s (PCI card address)
This command gives you the GPU vendors number.
c) Execute: nano /etc/modprobe.d/vfio.conf
Add this line with your GPU number and Audio number:
options vfio-pci ids=(GPU number,Audio number) disable_vga=1
Save file and exit the text editor

Step 7: Command to update everything and Restart
a) Execute: update-initramfs -u
b) Then restart the your Proxmox Node
