There are currently at least two BPs registered for VLAN trunk support to VMs in neutron-specs [1] [2]. This is clearly something that I'd like to see us land in Kilo, as it enables a bunch of things for the NFV use cases. I'm going to propose that we talk about this at an upcoming Neutron meeting [3]. Given the rotating schedule of this meeting, and the fact the Summit is fast approaching, I'm going to propose we allocate a bit of time in next Monday's meeting to discuss this. It's likely we can continue this discussion F2F in Paris as well, but getting a head start would be good.
