[Bug 1444966] [NEW] Clean up operation not performed properly by nova .
Public bug reported:
while I associate a floating IP to an instance and when I remove fixed IP associated to that instance , fixed IP as well as floating IP are removed but when I list floating IP for the current tenant , floating IP list still maintains the old data . Floating IP list still shows the attachment of the fixed IP with the instance from which it was removed that is required clean up operations was not performed properly .
I reproduced this bug using the following steps:-
