Description of problem: The installation guide does not explain the purpose or usage of the "Use Bridge" option in the RHEV-H network configuration menu.
After discussing this we agreed to removing the "Use Bridge" button. The reasoning behind it is, that this button is actually not needed to establish an initial connection with RHEV-M and there is no functional advantage of having the bridge. If a user needs a bridge, then he can still setup the required topologoy through RHEV-M - after the registration.
