Re: [vfio-users] Attempting IGD Passthrough on Kaby Lake



Works for me on a ASRock Z270 + i7-7700k.

Configuration: https://gist.github.com/f91530f56a1d1c98f48482456197f4ee

Also, make sure your UEFI BIOS selects the Intel GPU as the primary
graphics adapter.  You should see the system boot up on the IGD
display until your external GPU drivers are loaded.
