  ***IT DOES NOT HAVE TO BE MANUAL*** I have a 1-line script that shuts
down my hot-backup machine, which I bring up once a month for updates.
Here it is...

#!/bin/bash
ssh waltdnes@d531 sudo /sbin/poweroff

...with an appropriate entry in /etc/sudoers.d.  In your case, you can
have your script run like so (assuming the VM's port 22 is redirected to
60022)

#!/bin/bash
ssh -P 60022 root@localhost /sbin/poweroff

  I repeat, this is scriptable, and does not have to be manual.
