Are you using the disable_vga option of vfio-pci? What does this show? # cat /sys/module/vfio_pci/parameters/disable_vga Fedora kernels should have the right config options to enable VGA access through vfio. Run rom-parser on the ROM file to make sure it has a UEFI section and matches your device: https://github.com/awilliam/rom-parser Thanks, Alex _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
