This is wrong. Tap and internal are different kinds of interfaces. What does ovs-vsctl show that makes you confuse the two? > While I could not add a tap type interface to ovs as an internal type of > interface for OVS. > > The commands I used, > a) ip tuntap add dev tap0 mode tap. > b) ovs-vsctl add-port ovs0 tap0 -- set inteface tap0 type=internal These commands are wrong. If you create a tap interface, you must not tell ovs-vsctl that it is an internal interface. What led you to believe that these commands were correct? > error: "could not add network device tap12 to ofproto (No such device)" > > 2) My questions are , > a) how to add a tap interface to OVS and set it as internal type of > interface of OVS?
