You haven't really provided enough information to begin to help.  Are you
trying to do legacy mode or UPT for the GPU?  What's the QEMU command line
or XML for the VM?  Is IGD the primary graphics on the host?   What are the
CONFIG_VFIO_* options in the host kernel?  Is the VM SeaBIOS based or
OVMF?  Is the system a laptop or a desktop?  The less you can make trying
to help you a game of 20 question, the more help you're potentially going
to get.  Output to a monitor or laptop screen requires opregion support,
which generally works, but is not something Intel officially claims support
for with UPT mode.  I don't know why an i3-6100U would be unique, but I
only have a handful of devices to test and that processor is not among
them.  Thanks,

Alex
