[Users] Proper way to reboot an ovirt node

[Jonas Israelsson]

What is the recommended proper way reboot an Ovirt node ?

I started by putting the host into in Maintenance mode and was going to 
via the TUI interface just reboot the machine.
Should I then use the "confirm host rebooted" before I put the host back 
from Maintenance mode ?

I have rebooted my Nodes violently hundreds of times (and they have 
always recovered), but now I have data/config that I'm keen not to loose.
