Title:
Midonet plugin deletes port even when deletion of Quantum port fails
Status in OpenStack Neutron (virtual network service):
Expired
Bug description:
Context: Using midonet as the plugin for quantum with a grizzly OS
deployment, we have a VM instance with a floating ip associated through the
horizon dashboard.
When terminating this VM instance without first disassociation of the
floating ip, the delete_port() in quantum API call fails because of the
floating ip association still there.
In this situation, the corresponding midonet port is nevertheless
deleted by the midonet plugin although it should not. This creates
inconsistency of state and induces errors when the dashboard tries to
retrieve the floating IPs.
