Management of preferences belongs in application code, rather than libvirt. Library APIs need to have standard, predictable behaviour that apps can rely on in any deployment. We don't want that being changed globally for all applications by config files. Even if apps do want configuration data, we can't assume they want the data stored in configuration files. Any current GTK application will use GConf for any configuration, or in the future GSettings which has pluggable backends per OS platform.
