I am trying to install Liberty to Ubuntu 14.04using the official install guide. Everything worked until it came time to create the private network. I am on this page of the guide: http://docs.openstack.org/liberty/ins...

Command neutron net-create private results in this error:

Unable to create the network. No tenant network is available for allocation.

I was able to create the public network without problems. Now I can't create any networks and always get this same error. This errors happens for both admin and normal user.

neutron net-list

The error gets logged like this to /var/log/neutron/neutron-server.log (Other log files don't get errors.):
