Hi Ben Pfaff, Thanks for your quick reply. Yaa its work if I set a GRE tunnel "tunnel1" from VM1 to OpenVswitch( External) /Linux Machine and "tunnel2" from VM2 to OpenVswitch(External)/Linux Machine. In this setup, the OpenVswitch (External) creating two data paths dp0 and dp1 as each tunnel requi
