Both the machines I use (Frontend and Node) runs OpenSUSE 11.4. I followed very closely the documentation on how to install OpenNebula(2.2), but after an entire afternoon and no success, I'm turning to you guys.

However, when I link the node to the frontend with the onehost command, the node appears but with an 'ERROR' status. I did edit the oned.conf file with the Xen-related options and everything. So when I tried to figure why it was not working, I realized I couldn't connect from the frontend to the node with SSH (connection closed immediately by the node). This is really weird because it works perfectly the other way around (from the node to the frontend) not asking for any password or anything, which means that the problem does not come from the SSH Key/permissions.

It probably does. If the connection works in the direction host B to 
host A that does not mean the connection will work in the other 
direction. For a connection from B to A the sshd process on A determines 
whether you are able to connect or not and if you connect from A to B 
the sshd process on B determines whether you are allowed to connect or 
not. It sound like you do not have the authorized_key file set up 
properly on one of the hosts.

You can also take a look at this:
