If there are existing tools available or being developed we should use them, otherwise we should just define the process ourselves. > I don't know if it is a good idea to use libvirt's XML files > themselves for container config and start containers during libvirtd > start-up. I'm just thinking aloud here. What was your plan? I think that using the libvirt XML file format would be a good initial starting point, since its in keeping with the QEMU/KVM driver and there's no other pre-existing config file format available. You could have a dir /etc/libvirt/[your driver] to store them in. You'd be able to re-use much of the code in the existing qemu driver to this - I do similar re-use and file formats for the forthcoming storage API drivers.
