@Carlos,
This is not possible with the current branch of Odoo version 8, although it is being worked on in the master branch (check runbot.odoo.com master branch).
You can see multi-website/multi-domain support by logging into the backend (username and password are both admin) and by going to Settings >> Website Settings and clicking on the dropdown list at the top of the settings page (Create and Edit). You can add domains and connect them to companies in your database, and assign specific settings to those websites.
It is still under heavy development so it is not likely to be ready until version 9.0 due to the fact the database structure has already been frozen in odoo 8.0 stable.
