nova-cloud-controller next charm fails to set neutron.conf bind_host correctly

[Brad Marshall]

We're setting up Openstack with a 3 node HA cluster for the infrastructure, using Trusty and icehost, and revno 105 of the nova-cloud-controller next charm doesn't set bind_host correctly.

An extract of the /etc/neutron/neutron.conf file is:

[DEFAULT]
state_path = /var/lib/neutron
lock_path = $state_path/lock
bind_host =

which causes in the server.log:

If I set the bind_host by hand to 0.0.0.0, the neutron-server daemon restarts correctly - or at least, no longer complains about the "Cannot assign requested address."

Please let us know if you need any further information.

This is a regression from the recently landed prefer-ipv6 work.
