Has anyone tried running a F26/KDE guest in qemu/kvm and 4.12.8-300 kernel?

It seems I need to remove "rhgb quiet" from the start to get it to run. And, when I do get it to run I can't get the display size to change.

This was just a new install of a guest so the only other kernel I have kernel-4.11.11-300 works fine. I can boot to it, resize the window, and then use "xrandr --output Virtual-0 --auto" and the display will properly resize and continue to resize if I change the window size it is running within.

But with the 4.12.8-300 kernel while xrandr shows it has acquired the desired resolution it does not in-fact resize to fill the window.
