Settings

Settings covers the host itself rather than the machines running on it.

Host reboot and shutdown

Host reboot and shutdown are in the Danger Zone, where each action asks you to confirm first. See Danger Zone.

Administrator

Change the administrator password. The host has one administrator: the same password signs in to the console and to the host itself (console, SSH, sudo), so changing it changes both. Other sessions are signed out.

Virtainer web interface

The console is served on the default HTTP port, so its address needs no port number. You can move it to another port here.

Changing the port restarts Virtainer Free

Virtainer Free restarts to pick up the new port, so the console will be briefly unavailable and you will need to reconnect on the new port. The setting is stored on the host, and an OS update will not put it back to the default.

SSH access

Turn SSH access to the host on or off. With it off, reach the host through the console or its serial console.

This controls access to the host, not to the machines running on it. Those have their own SSH, configured through cloud-init.

VM autostart

Controls what happens to machines after the host reboots.

Setting	Behaviour after a reboot
On (default)	Machines that were running are started again automatically
Off	Machines that were running come back stopped, ready for you to start

This restores the last running state; it is not a hand-maintained boot order. Machines you stopped yourself are never started for you either way. See After a host reboot.
