Hello,

I am trying to install liberty in a lab with multiple dedicated machines (not VMs). I am following the installer for liberty step by step and I am stuck here: http://docs.openstack.org/liberty/install-guide-rdo/neutron-controller-install.html#neutron-controller-metadata-agent (http://docs.openstack.org/liberty/ins...)

Finalize installation Populate the database:

# su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \
  --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

When I run the command I get the following errors:

[root@controller ~]# su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \
>  --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
No handlers could be found for logger "neutron.quota"

sqlalchemy.exc.ArgumentError: Could not parse rfc1738 URL from string ''
[root@controller ~]#

I'm stuck at this point because neutron will not start if this db does not get populated.

Any help is greatly appreciated!
