OpenDaylight is probably dumping the flows that allow the SSH connectivity. Since OVS is just doing what ODL tells it, I think you'll have better luck asking followup questions on an ODL list.

What do you have in mind? If you generate traffic that goes through the Linux hypervisor's IP stack (e.g., sending traffic out a tunnel), you have control over what s1 can send, but you won't have control over eth0 directly. I don't think that's exactly what you're suggesting, though, so the answer is probably no.
