Thanks for the answer.
So i tried the guide, but i still end up with this error, when starting the VM:
Error starting domain: internal error: process exited while connecting to monitor: 2019-11-19T21:17:18.246383Z qemu-system-x86_64: -device vfio-pci,host=0000:02:00.0,id=hostdev0,bus=pci.3,addr=0x0: vfio 0000:02:00.0: group 1 is not viable
Please ensure all devices within the iommu_group are bound to their vfio bus driver.
