[Bug 1476417] Re: FloatingIpManager in neutron.py missing is_supported method

[Billy Olsen]

Thanks TimS for the analysis. It looks like this backport included a
portion of a blueprint which was not fully backported (namely not
showing the Floating IPs when they are not available). Rather than
backporting the full blueprint, dropping the checks for the is_supported
and simply assuming it is supported (which is what the previous code
did) should be an appropriate fix for the icehouse release.

Title:
  FloatingIpManager in neutron.py  missing is_supported method

Status in horizon package in Ubuntu:
  Confirmed

Bug description:
  The latest update to neutron (Version: 1:2014.1.5-0ubuntu1) caused the
  following error every time an instance is launched:

  "Unable to connect to Neutron."
  The logs didn't show any more errors.

  I traced down that string to the "servers_update_addresses" method in
  openstack-dashboard/api/neutron.py. I had to add a printout for the exception
  string to show where the exception happened:
  The modified error message now shows:
  Unable to connect to Neutron.'FloatingIpManager' object has no attribute
  'is_supported'

  
  It turned out that the latest neutron ubuntu package doesn't have the correct file update. A check is done on the fips.is_supported(), however the method itself is not implemented.

  
  The neutron.py on openstack's icehouse repository has the method implemented 
  http://git.openstack.org/cgit/openstack/horizon/tree/openstack_dashboard/api/neutron.py

  But the source code of the latest ubuntu package doesn't have the method
  http://archive.ubuntu.com/ubuntu/pool/main/h/horizon/horizon_2014.1.5.orig.tar.gz
