There's a standardized libosinfo namespace for libvirt domain metadata. For now it supports the id of the OS only. However that is still a very helpful feature that is already supported in gnome-boxes and virt-manager (at least). The discussion happened here: https://www.redhat.com/archives/libosinfo/2018-September/msg00003.html So let's add the support to local and libvirt outputs.
