So when you say, external snapshots aren't here yet, do you mean only
virt-manager? Do the other projects simply do no snapshots at all or are
they already employing them to such an extent that internal snapshots
are already regarded legacy by libvirt and qemu?

So if the actual fix would be to implement external snapshots in
virt-manager (preferably by generously borrowing what other projects are
doing), how much work would that be and how much is there or at least on
the roadmap already?

Sorry for my ignorance.
