Title:
  Cannot load 'instance' in the base class - problem in floating-ip-list

Status in OpenStack Compute (Nova):
  Fix Committed

Bug description:
  I tried the following on VMware using the VMwareVCDriver with nova-
  network:

  1. Create an instance

  2. Create a floating IP: $ nova floating-ip-create

  3. Associate a floating IP with the instance: $ nova floating-ip-
  associate test1 10.131.254.249

  4. Attempt a list of the floating IPs:
  $ nova floating-ip-list
  ERROR (ClientException): The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-dcb17077-c670-4e2a-8a34-715a8afc5f33)

  
  It failed and printed out the following messages in n-api logs:
