[Bit-dev] Working vagrant file for Arch Linux with a desktop (Xfce, KDE Plasma or Gnome)?

Has anybody of you a working vagrant file for me to quickly setup Arch with a desktop? I want to check and fix some BiT issues and working on the cmd line ain't no fun for this but neither Plasma nor Xfce will work whatever I try. I can login but get a black screen after seeing a rotating gear for a few seconds. Guest extensions are installed... THX!
