Open Stack

Hi Sushma,

Thanks, I think you solved it. Up to now OPENSTACK_NEUTRON_NETWORK was
completely commented out in local_settings.py. I commented it in with
enable_lb: False, and now Horizon shows :)

Thanks, now I have to fight a few other issues (currently Unauthorized
errors in cinderclient) but hey, at least a step forward...

Greetings & again thanks a lot!
