Hi, I'm seeing an issue in ovs that exposes another issue with OpenDaylight. This only happens with the ovs version compiled by the fuel plugin. When the last tap interface is deleted (i.e. whenever the last VM on a hypervisor is deleted), ovs segfaults, restarts and the wrong config is pushed by ODL. The segfault does not happen with ovs 2.4 or stock 2.5 stable. We probably need to somehow address this because this is not really a priority thing for ODL. It only happens when ovs restarts, normally or abnormally like with a segfault.
The things I have in mind to mitigate this are: 1) With ubuntu 16.04, we can probably just use stock ovs 2.5 for the VPN deployment. This will make it incompatible with SFC and iirc integration with SFC is one of the goals of the D release 2) Wait until it is fixed upstream. It might take a long time for that to be done (SR3?) 3) uplift to ovs 2.6. George is working on a patch that uplifts fuel plugin ovs to 2.6, I tested it and it seems that ovs no longer crashes. What are people's thoughts on this?
