Hi Gianni,
I have updated the documentation for the new set of ebtables scripts:

http://opennebula.org/doku.php?id=documentation:rel1.4:nm

Regarding your problems, please verify the following things:

* you have properly set the VM_HOOK configuration in oned.conf, especially
the remote = "yes" option, and restarted one.
* brctl is installed in your worker nodes
* oneadmin user has permissions to execute "sudo ebtables" and "sudo virsh"
in the worker nodes.

regards,
Jaime
