To prepare hosts to participate in NSX-T Data Center, you can manually install NSX-T Data Center kernel modules on Ubuntu KVM hosts. This allows you to build the NSX-T Data Center control-plane and management-plane fabric. NSX-T Data Center kernel modules packaged in DEB files run within the hypervisor kernel and provide services such as distributed routing, distributed firewall, and bridging capabilities.
You can download the NSX-T Data Center DEBs manually and make them part of the host image. Be aware that download paths can change for each release of NSX-T Data Center. Always check the NSX-T Data Center downloads page to get the appropriate DEBs.
- Verify that the required third-party packages are installed. See Install Third-Party Packages on a KVM Host.
- Log in to the host as a user with administrative privileges.
- (Optional) Navigate to the /tmp directory.
- Download and copy the nsx-lcp file into the /tmp directory.
- Untar the package.
tar -xvf nsx-lcp-<release>-ubuntu-trusty_amd64.tar.gz
- Navigate to the package directory.
- Install the packages.
sudo dpkg -i *.deb
- Reload the OVS kernel module.
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.
- To verify, you can run the dpkg –l | grep nsx command.
user@host:~$ dpkg -l | grep nsx ii nsx-agent <release> amd64 NSX Agent ii nsx-aggservice <release> all NSX Aggregation Service Lib ii nsx-cli <release> all NSX CLI ii nsx-da <release> amd64 NSX Inventory Discovery Agent ii nsx-host <release> all NSX host meta package ii nsx-host-node-status-reporter <release> amd64 NSX Host Status Reporter for Aggregation Service ii nsx-lldp <release> amd64 NSX LLDP Daemon ii nsx-logical-exporter <release> amd64 NSX Logical Exporter ii nsx-mpa <release> amd64 NSX Management Plane Agent Core ii nsx-netcpa <release> amd64 NSX Netcpa ii nsx-sfhc <release> amd64 NSX Service Fabric Host Component ii nsx-transport-node-status-reporter <release> amd64 NSX Transport Node Status Reporter ii nsxa <release> amd64 NSX L2 Agent
Any errors are most likely caused by incomplete dependencies. The apt-get install -f command can attempt to resolve dependencies and re-run the NSX-T Data Center installation.
What to do next
Add the host to the NSX-T Data Center management plane. See Deploy NSX Manager Nodes to Form a Cluster Using CLI.
