By the way, I maintain a set of Vagrant boxes that allow me to test my extension on different distros and GNOME Shell versions GitHub - ddterm/gnome-shell-box: Vagrant libvirt boxes with GNOME Shell HashiCorp Cloud Platform
I try to make VM images that represent “stock” GNOME installation for the distro. But, unfortunately, it’s not always possible. For example, Fedora Workstation doesn’t support unattended installation (correct me if I’m wrong, PRs are welcome), so I’m trying to reproduce it from netinstall.
Also, Vagrant (and, especially, vagrant-libvirt) isn’t my favorite piece of software (IMO it has way too many dependencies for what it does) - but Hashicorp provides free hosting for public Vagrant boxes
