I'm getting this too. Fresh OpenSuse Tumbleweed install with Xorg and KDE in a qemu/libvirt virtual machine. I've tried changing the video card types from virtio, vga, qxl to no...

No, just KDE.

I just quick fixed it on mine, because I only need access for one user. I wrote a script (~/.local/bin/xhost.sh) and have kde autostart it. Other options (for all users)...
