Public bug reported:

I've installed libverty openstack release on Ubuntu 14.04 with flat network. 
The openstack release is 12.0.0. 

dpkg -l | grep nova-common
ii  nova-common                                   2:12.0.0-0ubuntu2~cloud0                            all          OpenStack Compute - common files

Everything seems to work fine, except horizon. 
When I logged in , getting an error message "Error: Unable to retrieve floating IP addresses."
Provisioning of VMs is not working in horizon, failed with error. But nova boot is working fine and instance is up and running. 
Also when I try to run the commands :
      nova floating-ip-list
ERROR (ClientException): Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
