  The tool for stopping/starting running system vms and domain routers. It requires integration API port to be enabled.

  Usage: %s: [-d] [-u] [-p] [-m] [-s] [-r] [-a] [-n] [-t] [-l] [-z] [-v] [-i] [-j]

   -d - cloud DB server ip address, defaulted to localhost if not specified
   -u - user name to access cloud DB, defaulted to \"root\" if not specified
   -p - cloud DB user password, defaulted to no password if not specified
   -m - the ip address of management server, defaulted to localhost if not specified
   -s - stop then start all running SSVMs and Console Proxies
   -r - stop then start all running Virtual Routers
   -a - stop then start all running SSVMs, Console Proxies, and Virtual Routers
   -n - restart all Guest networks
   -t - number of parallel threads used for stopping Domain Routers. Default is 10
   -l - log file location. Default is cloud.log under current directory
   -z - do restart only for the instances in the specific zone. If not specified, restart will apply to instances in all zones
   -v - do restart all VPCs in the entire system
   -i - do restart on instances with specific IDs. Comma-separated instance IDs to be provided. Works only when restarting SSVMs, CPVMs or VRs
   -j - do restart on instances from the specified database table. If not specified, restart will apply on instances present in cloud.vm_instance database table. Works only when restarting SSVMs, CPVMs or VRs\n\n"
