late to the party... but I'll dabble.

We've been discussing using Open vSwitch as the basis for non-Quantum Nova

bringing Nova Networking a step closer to some of the core technologies that
Quantum uses.

To what end?

OVS provides much more robust monitoring and operational facilities (e.g sFlow monitoring, better switch table visibility etc). It also provides a linux-bridge compatibility layer (ovs-brcompatd [1]), which should work out-of-box with the linux-bridge. As such, switching to using OVS rather than the linux bridge could be done without any code changes to nova, just deployment changes (e.g. ensure that ovs-brcompatd is running to intercept brctl ioctl's - [2]).

For the more adventurous, there could be any number of interesting scenarios enabled by having access to ovs capabilities (e.g. tunneling)

I'm interested in hearing what other's in the community think about this
approach.

I'm similarly curious if any *operators* have experimented with OVS and sFlow or other of its capabilities.

I don't think legacy nova networking should get features while working to stabilize and improve quantum and nova/quantum integration.
