I put the vfio-pci ids and vfio-pci disable_vga=1 on the /etc/modprobe.d/vfio-pci.conf. 2.) I put intel_iommu=on iommu=pt rd.modules-load=vfio-pci on the kernel command line. 3.) Regenerate initramfs of the kernel everytime I make changes in vfio-pci ids. I found myself failed to bind devices to VFIO if I forgot to update initramfs after changing vfio-pci ids in /etc/modprobe/vfio-pci.conf. Have you tried updating your initramfs image?
