I am trying to provision baremetal with openstack using ironic. I followed http://docs.openstack.org/developer/i.. . ( http://docs.openstack.org/developer/i.. . ) for installing ironic.

But when I tried to deploy baremetal through horizon, I am getting "Failed to Get IP address on Neutron port 7d71215a-5942-4716-9054-f8bbfcdff73f"

Please help me on this. Here is some information

ironic node-validate $NODE
