Title:
StaleDataError in disassociate_floatingips
Status in neutron:
Expired
Bug description:
If a VM with a floating IP is deleted while concurrently deleting the
floating IP (i.e. "nova delete" and "neutron floatingip-delete") the
VM may go into error state.
Nova receives a 500 error code from neutron because neutron fails to
delete the port and the following stack is observed:
