-readconfig and -writeconfig are documented badly. They use an INI file format[*]. Unfortunately, it covers only a subset of the command line options. The (flawed!) QMP command query-command-line-options currently shows exactly the covered ones. I second Laszlo's recommendation to check out existing solutions such as libvirt before rolling your own.
