Stephen, thanks for asking for input. You might want to cross-post to 
the openstack-operators mailing list if you're looking for operational 
input on these features in nova. It's fun to fish either way. :)

One immediate thing is we approved this spec for Ocata:

https://blueprints.launchpad.net/nova/+spec/sriov-pf-passthrough-neutron-port-vlan

But there is no code up for review yet. I'm getting a bit antsy about 
blueprints that don't have code yet for Ocata, and this change seems 
pretty straight-forward, so it would be good to get some people driving 
that.
