Hey, See: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=238492 Basically, doing a "service libvirtd restart", you see: libvirt-qemud: Failed to autostart network 'default': cannot create bridge 'virbr0' : File exists and the default network is broken. The problem turns out to be that the initscript doesn't wait before the old daemon has shut down before starting the new one. The fix is simple - if you don't pass a kill level argument to killproc(), then it will block for a few seconds until the daemon has shutdown before killing it with a SIGKILL. Cheers, Mark.
