Open Stack

Dmitry, good night!

I decided to start from scratch and remove things that I won't be using (at
least not now).

When removing the flat network the errors are gone and the VMs start.

I just have another question related to Neutron, but I'll start another
thread.

Thanks a lot for the help!
