Public bug reported: Nova can cause a neutron port leak after deleting an instance.
If neutron has the port binding extension installed, then nova uses admin credentials to create the port during instance create: https://github.com/openstack/nova/blob/master/nova/network/neutronv2/api.py#L537 However, during instance delete, nova always uses the user creds: https://github.com/openstack/nova/blob/master/nova/network/neutronv2/api.py#L739 Depending on the neutron policy settings, this can leak ports in neutron. Can someone explain this behavior? We are running on nova kilo. ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
