Description of problem:
When booting current Fedora 26 as a virtual guest in gnome-boxes, the system
does not reach GDM. It gets stuck during the graphical boot procedure. After
removing boot option "rhgb", the system gets frozen after attempting to launch
the graphical login manager GDM.

Version-Release number of selected component (if applicable):
kernel-4.12.5-300.fc26

How reproducible:
Always

Steps to Reproduce:
1. Boot current Fedora 26 virtual guest in gnome-boxes.

Actual results:
System gets stuck during the graphical boot procedure.

Expected results:
System launches GDM successfully.

Additional info:
- After adding boot option "nomodeset", the system launches GDM on Xorg
successfully.
- After removing "rhgb" from the kernel options and running 'startx' at run
level 3, the GNOME on Xorg session starts up as expected.
- After changing the video device from "qxl" to "virtio", the system launches
GDM on Wayland successfully.
- This issue was introduced in the 4.12.x kernel series and now also affects
4.13.x kernel series.
