The way I installed the sr-iov patches is via dkms:

  • install dkms kernel-devel kernel-latest-devel in dom0 and gpu-hvm template
  • download latest release zip from GitHub - strongtz/i915-sriov-dkms: dkms module of Linux i915 driver with SR-IOV support
  • copy into dom0 qvm-run --pass-io <src-vm> 'cat /path/to/i915-sriov-dkms-2025.02.03' > /path/to/i915-sriov-dkms-2025.02.03 and to gpu-hvm template qvm-copy i915-sriov-dkms-2025.02.03.zip
  • unzip release zip unzip i915-sriov-dkms-2025.02.03.zip
  • add to dkms via dkms add ./i915-sriov-dkms-2025.02.03
  • install module via dkms install i915-sriov-dkms/2025.02.03
  • kernel commandline needs to be adjusted: vim /etc/default/grub and change GRUB_CMDLINE_LINUX_DEFAULT to intel_iommu=on i915.enable_guc=3 i915.max_vfs=7 module_blacklist=xe, or add to it if you have other arguments there already.
  • update grub config grub2-mkconfig -o /boot/efi/EFI/qubes/grub.cfg (dom0)
  • rebuild initramfs dracut --regenerate-all --force
  • after rebuild I can enable the virtual devices via echo 7 > /sys/devices/pci0000\:00/0000\:00\:02.0/sriov_numvfs

I did the same on the VM template in my case fedora-40 only leaving out the i915.max_vfs=7 kernel parameter.

After setting everything up and making sure all kernel options are in place I tried passing through one of the GPUs to the new VM but I get the libxenlight failed to create a domain when trying to start it with GPU attached. Permissive / no-strict-reset for the gpu didn’t fix it.

I’ll try to create a debian-13 template analog to 1x3n1x’s setup and will see if it changes anything. If not I guess I can wait another 2 weeks for his howto after many years without gpu acceleration on Qubes :slight_smile:
