     During my try to use it, it is,  the same situation happens on 
nwfilter and storage
     driver. It has to deactivate all of these running resources

     According to the comment 1 from Daniel in BZ831049,
     "The timeout option is primarily intended for use with the 
non-privileged libvirtd
     when it has been auto-spawned by a client app."
