libvirt/tests/virnetdaemontest.c
Erik Skultety 252610f7dd virnetdaemon: Store servers in a hash table 
Since the daemon can manage and add (at fresh start) multiple servers,
we also should be able to add them from a JSON state file in case of a
daemon restart, so post exec restart support for multiple servers is also
provided. Patch also updates virnetdaemontest accordingly.
