I'm a big advocate of using a sane language instead of C, but libvirt is written in C for better or worse. The problem with a separate daemon is management of that daemon. Something needs to start it and stop it, it needs to have sockets with the right permissions and so on. What happens if the process runs and can't find the daemon? What is the path to the socket? etc. etc. At the moment we have two daemons - the qemu daemon (which has two separate functions intertwined), and a remote daemon (necessary, because there's no other way to communicate to a remote machine). One idea would be to have the Python code fork off from the main program and communicate over a pipe. With this, there is no daemon management problem. +----------------+ | Program | | - - - - - - - -| | libvirt | +----------------+ | | fork(2) and pipe(2) | +-------------+ | Python code | +-------------+ But I'm not the person who ultimately decides what would be acceptable in libvirt. You'd need to get general agreement on the best way to do this.
