# What ? This kickstart file enables vfio-mdev and KVMGT for compatible Intel(tm) graphic cards, allowing a host to create virtual GPUs.
# The fifth generation of Broadwell-based SoC are compatible, up to the ninth generation (Cannon Lake and Whiskey Lake). Tiger Lake and later SoC based on the new Xe GPU architecture are not compatible, as they use SR/IOV instead.
