Public bug reported:

Hi,

I follow the link https://docs.openstack.org/neutron/train/admin/config-
ovs-offload.html, it use system datapath_type, and it works well, after
I change the ovs to ovs-dpdk, the os-vif still plug the vf port to br-
int, see below

    Bridge br-int
        Controller "tcp:127.0.0.1:6633"
        fail_mode: secure
        datapath_type: netdev
        Port int-br-ex
            Interface int-br-ex
                type: patch
                options: {peer=phy-br-ex}
        Port "ens2f1_2"
            Interface "ens2f1_2"
        Port br-int
            Interface br-int
                type: internal

as you can see the datapath_type use netdev now, it should use the below
command,

ovs-vsctl add-port br0 dpdk-rep3 -- set Interface dpdk-rep3 type=dpdk \
   options:dpdk-devargs=0000:08:00.0,representor=[3]

see http://docs.openvswitch.org/en/latest/topics/dpdk/phy/


solution

I will patch the code to fill datapath_type field in
_get_ovs_representor_port_profile in nova/network/os_vif_util.py
