| We’re running Quantum (in Grizzly) with OvS+GRE overlay networking with KVM

Yes, I'm aware of people proposing approaches that involve using virtual appliances for packet forwarding instead of the in-kernel vSwitch. Perhaps there are other approaches as well (e.g., SR-IOV + HW). 

I focused on NSX + nova-network because I started the email by saying " In my experience working with customers...", and I have never seen anything other than those two options running in production.
