• Check the guest can be reached via ping, if yes:

  • Issue the shutdown command via "ssh" (depends on the operating system),

  • Wait for a few seconds

  • Check if the guest can be "pinged" and repeat with an interval of 5 seconds

  • If the guest cannot be pinged, assume the shutdown procedure is complete

• Kill the emulator process (Red Hat Enterprise Linux 6.x) or use the service kill command (RHEL/CentOS 7 and 8). The shutdown commands does not power off nor stop the emulator process, that's why this operation is needed

• Report the stop information within the guest log file
