Hi keshava, We would like contribute towards service chain and NFV Could you please share the document if you have any related to service VM The service chain can be achieved if we able to redirect the traffic to service VM using ovs-flows in this case we no need to have routing enable on the service VM(traffic is redirected at L2). All the tenant VM's in cloud could use this service VM services by adding the ovs-rules in OVS Thanks -Murali -------------- next part -------------- An HTML attachment was scrubbed...
