I agree that vnet1 and vnet2 should not be able to reach each other. Run "ovs-dpctl show" and show us the output. Then start a "ping" between them, with little other traffic, and while it's going run "ovs-dpctl dump-flows realbridge". Also it'd be helpful to see the output of "route -n" and "ifconfig".
