1) From the openstack documents, we know that for the tenant's dhcp functionality, the usage is to connect a dhcp netns to the ovs using a tap interface.
At the same time, the ovs-vsctl show that the tap interface is a type of internal interface for OVS.
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
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?
b) Even if the tap interface could be added into ovs, could it be added into a netns again? If the tap interface could be added into ovs and a netns, how the traffic flows between the ovs and netns.
