Title:
Nova API floating IP delete fails
Status in OpenStack Compute (nova):
Expired
Bug description:
This happens with OpenStack Newton.
We use some outdated openstack clients, that do not provide the "floating ip
delete" command. Therefore we use the "ip floating delete" command.
The floating IP is allocated using the "ip floating create" command. The
floating IP is then associated to a newly started virtual machine.
After some automated tests, the command to delete the virtual machine is
sent. To keep the project clean, the floating IP is deleted afterwards using
the "ip floating delete" command. This command fails from time to time due to
some race condition.
This race condition seems to be the following. Nova API requests
information about the floating IP from neutron:
GET /v2.0/floatingips/3aeb2a7e-ac37-4712-ac69-80dc83a060e6.json HTTP/1.1
Host: controller:9696

In the response the floating IP still seems to be associated to the
virtual machine - but the request to delete the virtual machine was
already sent.
Nova API requests information about the port, too:

But the virtual machine and its floating IP association seems to be
deleted in the meantime. This makes Nova API fail to delete the
floating IP:
