About this task

Procedure

  1. In OVSDB, setup the dpdk-extra parameter as in the following example:
    # ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-extra=”-n6 \
    –vdev=eth_ntnic0,port=0 –vdev=eth_ntnic1,port=1 -a 0000:3b:00.4 \
    -a 0000:3b:00.5 -a 0000:3b:00.6”
    

    This configures 3 ports, the mandatory VF#0 and then additionally VF#5 and VF#6. These are now configured with 1 queue each.

  2. For a multiqueue setup, add the portqueues[] parameter to VF#0 as in the following example:
    # ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-extra=”-n6 \
    –vdev=eth_ntnic0,port=0 –vdev=eth_ntnic1,port=1 \
    -a 0000:3b:00.4,portqueues=[5:2,6:2] -a 0000:3b:00.5 -a 0000:3b:00.6”

    VF#5 with 2 queues and VF#6 with 2 queues is created.

  3. In OVSDB, define OVS representor virtual ports as in this OVS bridge example:
    # ovs_vsctl add-port br0 dpdkvp0 – set interface dpdkvp0 \
    type=dpdk options:dpdk-devargs=”0000:3b:00.5”
    
    0dd0725f-53fe-45e4-8b96-95d4a2e7a674
        Bridge "br0"
            datapath_type: netdev
            Port "dpdkvp0"
                Interface "dpdkvp0"
                    type: dpdk
                    options: {dpdk-devargs="0000:3b:00.5"}
            Port "dpdkvp1"
                Interface "dpdkvp1"
                    type: dpdk
                    options: {dpdk-devargs="0000:3b:00.6"}
            Port "br0"
                Interface "br0"
                    type: internal
            Port "dpdk1"
                Interface "dpdk1"
                    type: dpdk
                    options: {dpdk-devargs="eth_ntnic1"}
