Open Stack

Hey guys! Never mind! Someone within my network, registered the same IP of
Neutron in a new server...

It was entirely my problem, nothing to do with OpenStack IceHouse or Ubuntu.

I just don't understand why Neutron triggered that error with Namespace,
this was the source of my confusion...

Everything is running fine now, sorry about the buzz...   :-P
