[Libvir] [PATCH] Remote 6/8: Server-side QEMUD modifications

Again, this is Dan's patch to make QEMUD use the XDR protocol: http://www.redhat.com/archives/libvir-list/2007-March/msg00333.html The modifications I have made: (1) Use REMOTE_MESSAGE_MAX from remote_protocol.x (2) Make the protocol superficially similar to the remote protocol so that we can dispatch on it, although in the current implementation this is actually not used. Instead we make our dispatch decision based on whether the daemon was started with --remote on the command line. (3) Allow the daemon to listen on TCP sockets. (4) Allow the daemon to require GnuTLS encryption negotiation on sockets. In addition, the daemon can now check the client's IP address and certificate against a whitelist. (5) Add support for a configuration file (/etc/libvirt/libvirtd.conf by default, but can be overridden on the command line), which allows the sockets and certificate stuff to be configured. To do: Find a good default place in the filesystem to find the CA and client certificates. Change the start-up script so that it can start a QEMU/network daemon and a remote daemon.
