Cannot open iommu_group: No such file or directory

[Goetterfunke87]

Hi There,
firstly, Thank you for this wonderful image. I'm testing with it for a while now and almost everything works (better) as expected.
Today I tried using passing through PCI-E device to QEMU but even with all required modules loaded with modprobe I'll get the following error: Cannot open iommu_group: No such file or directory
Maybe that's something for one of the next releases.
Thank you & best Regards
