Question

I want to write a script which can Shutdown remote Ubuntu system. Actually i want my VM to shutdown safely when i shutdown my main machine on which my VM is installed .

Is there is any of doing this with the help of Sh scripts or script written in any language like Python.

Answer 1

You can run the following command from a remote Linux machine (VM Host):

ssh root@<vm-client-ip> "shutdown -h now"

You will have to input your root password for the remote machine. You can prevent this by adding ssh certificates (good if you are writing a script):

SSH login without password

If you make a script out of this, don’t forget to add a delay after the shutdown (e.g. sleep 10) so that the VM will have time to die peacefully.

A complete bash script (untested):

#!/bin/bash

ssh root@<vm-client-ip> "shutdown -h now"
sleep 10
