This piece of data is important post-install though: if the user adds a new disk to the VM later, we want to be able to ask libosinfo about what devices the installed OS supports, so we can set optimal defaults, like enabling virtio.There isn't any standard libvirt XML field to track this kind of info though, so apps have to invent their own schema. nova and rhev do it indirectly AFAICT. gnome-boxes does it directly with XML like this: <metadata> <boxes:gnome-boxes xmlns:boxes="https://wiki.gnome.org/Apps/Boxes";> <os-id>http://fedoraproject.org/fedora/28</os-id> .... </boxes:gnome-boxes> </metadata> I want to add something similar to virt-manager but it seems a shame to invent our own private schema for something that most non-trivial virt apps will want to know about. I was thinking a schema we could document with libosinfo, something like <metadata> <libosinfo xmlns:libosinfo="http://libosinfo.org/xmlns/libvirt/domain/1.0";> <os-id>http://fedoraproject.org/fedora/28</os-id> </libosinfo> </metadata>Yes, I would like to see this standardized under <matadata>.
Me too and what Cole suggested looks fine.
