--- Comment #13 from Gerd Hoffmann (kraxel@redhat.com) ---
Workaround #1: turn off wayland.
Possible as a short term fix, but with wayland being pretty much "the way forward" it doesn't seem to be a workable long term solution.
Yes.
So this brings up an interesting problem in how things are to move forward.
Kicked discussion on spice-devel list. https://lists.freedesktop.org/archives/spice-devel/2017-October/040310.html
It came up as a blocker in Fedora 27 today. Let's say we find a way to force boxes to revert to virtio-vga. That wouldn't change any existing VMs, and it is something we have no control over when the host is not Fedora as well.
That would probably best done via libosinfo (because for guests without virtio-vga guest drivers we better don't do the switch). Which should be picked up by other distros and projects too.
It also would be a problem for non wayland guests.
Why? The xorg modesetting driver works just fine with virtio-vga.
