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


  1. Download the installation file for your Linux distribution.

    The filenames are openvswitch-common_2.7.0.6383646-1_amd64.deb, openvswitch-datapath-dkms_2.7.0.xxxxxxx-1_all.deb, and openvswitch-switch_2.7.0.xxxxxxx-1_amd64.deb, where xxxxxxx is the build number.

  2. Install the rpm or deb file downloaded in step 1.
  3. For Ubuntu, run the following command to reload the OVS kernel module.
        service openvswitch-switch force-reload-kmod
  4. Make sure that OVS is running.
        # service openvswitch-switch status
  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:
