Hi Seán, Michael,
Since patch [1] moved Contrail VIF plugging under privsep, Nova fails to
plug TAP on the Contrail software switch (named vrouter) [2]. I proposed
a fix in the beginning of the year [3] but it still pending approval
even it got a couple of +1 and no negative feedback. It's why I'm
writing that email to get your attention.
That issue appeared during the Queens development cycle and we need to
fix that before it was released (hope we are not to late).
Contrail already started to move on os-vif driver [4]. A first VIF type
driver is there for DPDK case [5], we plan to do the same for the TAP
case in the R release and remove the Nova VIF plugging code for the vrouter.

Approved the change on master and working on the backport to
stable/queens. We'll be cutting an RC3 tomorrow so I'll make sure this
gets into that.
