Is there an guide for adding host to OpenNebula 4.12.1?

I’m an completly newbie.
I’ve search and searched for an guide on how to add a new host to an existing OpenNebula enviroment, but I can’t find any.
Does any one know of such a guide?

Hi, I believe this is what you’re looking for:

Particularly ‘Create and Delete’ section.

kcloud is right, but first you need to install SW on node.
