Demo 2

This script shows how an admin can run a progam on a guest OS and check the results of that program.

There are two functions defined, use_tools() and cleanup(). The admin can pick one of the two. A possible use case is this.

>>> import demo2
>>> demo2.use_tools()

cleanup()

def cleanup():
    host= Host()
    host.connect()
    vm= host.openVM(guest_os)
    vm.power_off()

Here’s a main program switch that simply runs both steps.

if __name__ == "__main__":
    logging.basicConfig( stream=sys.stderr, level=logging.DEBUG )
    use_tools()
    cleanup()
