To prepare hosts to participate in NSX-T, you can manually install NSX-T kernel modules on RHEL KVM hosts. This allows you to build the NSX-T control-plane and management-plane fabric. NSX-T kernel modules packaged in RPM files run within the hypervisor kernel and provide services such as distributed routing, distributed firewall, and bridging capabilities.

About this task

You can download the NSX-T RPMs manually and make them part of the host image. Be aware that download paths can change for each release of NSX-T. Always check the NSX-T downloads page to get the appropriate RPMs.

Prerequisites

Ability to reach a RHEL repository.

Procedure

  1. Log in to the host as an administrator.
  2. Download and copy the nsx-lcp file into the /tmp directory.
  3. Untar the package.
    tar -zxvf nsx-lcp-<release>-rhel73_x86_64.tar.gz
  4. Navigate to the package directory.
    cd nsx-lcp-rhel73_x86_64/
  5. Install the packages.
    sudo yum install *.rpm

    When you run the yum install command, any NSX-T dependencies are resolved, assuming the RHEL host can reach the RHEL repository.

  6. Reload the OVS kernel module.
    /etc/init.d/openvswitch force-reload-kmod

    If the hypervisor uses DHCP on OVS interfaces, restart the network interface on which DHCP is configured. You can manually stop the old dhclient process on the network interface and restart a new dhclient process on that interface.

  7. To verify, you can run the rpm -qa | egrep 'nsx|openvswitch|nicira' command.

    The installed packages in the output must match the packages in the nsx-rhel73 directory.

What to do next

Add the host to the NSX-T management plane. See Join the Hypervisor Hosts with the Management Plane.
