Hi Sam, just stumbled upon this one.
Is this bug still valid?
If you think so, I will have a look at it.

Since the log link was old, got the recent logs for ODL netvirt master:

NPE is in deleteVpnInterface, caused due to fetching the concerned port in ODL/Neutron Ports Config DS and finding it absent there.

1. This is strange in the first process, since no remove() DCN on NeutronPortChangeListener is received for the same.

2. Some intermediate TRACE logs on neutronvpn-impl seem missing since add() for the same port at least should have come, as also reflected by further processing, but the absence of add() calls looks absurd.

3. Anyway, this exception lands for an IPv6 port, since VPNService is not currently processing IPv6 ports and subnets, thinking through a fix to filter out such ports and subnets at NeutronVPN level itself, to avoid further processing of the same (population in subnetmaps, leading to notifications, etc).

Missed adding the log above: https://logs.opendaylight.org/releng/jenkins092/netvirt-csit-1node-openstack-mitaka-gate-transparent-carbon/475/archives/odl1_karaf.log.gz
