Comment 4 for bug 1040956

From the attachment, the issue appears to be this:

  nova/api/openstack/compute/contrib/floating_ips.py", line 154, in index
     floating_ips = self.network_api.get_floating_ips_by_project(context)
  nova/network/quantumv2/api.py", line 260, in get_floating_ips_by_project
      raise NotImplementedError()

Looks like Horizon is trying to list floating IPs from Nova and this doesn't work with Quantum

Serious issue, but unclear whether this will be fixed in Horizon or Nova at this point - targeting to nova's rc1 milestone for now
