Similar to Rebooting a virtual machine from the Cloud+ console, we also have access to a ‘Shut Off’ function:
This will send a ‘nice’ shutdown command to the controlling software for the virtual machines for your account, and send a “Power key” event to the virtual machine.
The Operating System’s visibility of this process can again be viewed from most logs, e.g. from journald in this example:
ubuntu@example-server:~$ journalctl -b-1 --no-pager -u systemd-logind --since 08:32:28
-- Logs begin at Thu 2021-04-08 08:27:30 UTC, end at Thu 2021-04-08 08:44:10 UTC. --
