What? https://libvirt.org/formatdomain.html


Thanks.
I think this is a good piece of news.
I still think that libvirt is not doing something qemu-kvm cannot do on its
own.

And I am willing to know how, as I said earlier.

Why not use libvirt? It even has a documentation on live backups:

I don't know if it's possible with plain qemu.



Because all libvirt stuff starts with "copy this XML file and customize it"
and there's little or no documentation about that XML.

And because I need to understand the hardcore stuff before going the soft
way.
