[Bug 997763] Re: floating ips are not disassociated from instances on deletion

[Patrizio Bassi]

I still have a similar issue on Newton release using Designate.

When adding an instance with a floating ip i can get both records set.
When i de-associate the floating ip designate correctly removes it. when
i destroy the instance (nova destroy) without explicit floating ip
deassociation it doesn't get removed from designate record list.

Any idea/workaround?

Bug description:
  The following scenario does not work:

  nova add-floating-ip <instance> <floating_ip>

  nova delete <instance>

  nova "floating-ip-list" renders error like this:
  "The server has either erred or is incapable of performing the requested operation"

  This is because there's still mapping between the fixed ip of the deleted instance and floating ip left.
  Right now one must explicitly type:
  nova remove-floating-ip <instance> <floating_ip>
  nova delete <instance>
