When running in libvirtd, we are happy for any of the drivers to simply skip their initialization in virStateInitialize, as other drivers are still potentially useful. When running in per-driver daemons though, we want the daemon to abort startup if the driver cannot initialize itself, as the daemon will be useless without it.
