However, enabling ssh will prompt a 'configuration issue' that just won't go away.
Fortunately there is a way to clear it. With your newly acquired ssh abilities, log into the server and restart the services like this:
# /sbin/services.sh restart
Give it a minute and you'll have easy access to your ESXi servers, able to survive a reboot without a pesky warning.
