I created a vfio-pci.cfg but the binding doesn't seem to work. I get the same result as not having a vfio-pci.cfg file:

2019-09-21T05:40:54.449416Z qemu-system-x86_64: -device vfio-pci,host=65:00.0,id=hostdev0,bus=pci.5,addr=0x0: vfio 0000:65:00.0: group 28 is not viable
Please ensure all devices within the iommu_group are bound to their vfio bus driver.

I am able to start the VM if I edit the Syslinux configuration with "{append initrd=/bzroot} vfio-pci.ids=10de:1e81,10de:10f8,10de:1ad8,10de:1ad9" but this is another post.
