Intel vgpu guest display shows up in the qemu gtk window. This is a linux kernel booted to the dracut emergency shell prompt, with the framebuffer console running @ inteldrmfb. Booting a full linux guest with X11 and/or wayland not tested yet. There are rendering glitches too, running "dmesg" looks like this:

So, a bunch of issues to solve before this is ready for users, but it's a nice start.

For the brave:

qemu: https://www.kraxel.org/cgit/qemu/log/?h=work/intel-vgpu

Take care, both branches are moving targets (aka: rebasing at times).
