Install and configure OVS (Open vSwitch) on the minion nodes.


  1. Download the installation file for your Linux distribution.
    The filenames are openvswitch-common_2.10.x.xxxxxxx-1_amd64.deb, openvswitch-datapath-dkms_2.10.x.xxxxxxx-1_all.deb, and openvswitch-switch_2.10.x.xxxxxxx-1_amd64.deb, where xxxxxxx is the build number.
  2. Install the deb file downloaded in step 1.
  3. For Ubuntu, run the following command to reload the OVS kernel module.
        # systemctl force-reload openvswitch-switch
  4. Make sure that OVS is running.
        # systemctl status openvswitch-switch.service
  5. Create the br-int instance if it is not already created.
        # ovs-vsctl add-br br-int
  6. Add the network interface (node-if) that is attached to the node logical switch to br-int .
        # ovs-vsctl add-port br-int <node-if> -- set Interface <node-if> ofport_request=1
    Run the following command to see what ofport is, because if ofport 1 is not available, OVS will assign a port that is available.
        # ovs-vsctl --columns=ofport list interface <node-if>

    If ofport is not 1, set the ovs_uplink_port option in the nsx_kube_proxy section of the NSX node agent DaemonSet yaml file accordingly.

  7. Make sure that the br-int and node-if link status is up.
        # ip link set br-int up
        # ip link set <node-if> up
  8. Update the network configuration file to ensure that the network interface is up after a reboot.
    For Ubuntu, update /etc/network/interfaces and add the following lines:
        auto <node-if>
        iface <node-if> inet manual
        up ip link set <node-if> up
    For RHEL, update /etc/sysconfig/network-scripts/ifcfg-<node-if> and add the following line:
