Libvirtd needs a configuration file. It's very simple - just to store the services on which it's listening, and optionally to configure port numbers and paths. Libvirt so far doesn't have a concept of a configuration file, except that obviously domain descriptions come out of XML files. Do people on list have a preference for a style of configuration file? An alternative is to configure entirely via the command line. Rich.
