When hypervisor hosts are prepared to operate with NSX-T, they are known as fabric nodes. Hosts that are fabric nodes have NSX-T modules installed and are registered with the NSX-T management plane. Install Third-Party Packages on a KVM HostTo prepare a KVM host to be a fabric node, you must install some third-party packages. Add a Hypervisor Host to the NSX-T FabricA fabric node is a node that has been registered with the NSX-T management plane and has NSX-T modules installed. For a hypervisor host to be part of the NSX-T overlay, it must first be added to the NSX-T fabric. Manual Installation of NSX-T Kernel ModulesAs an alternative to using the NSX-T Fabric > Nodes > Hosts > Add UI or the POST /api/v1/fabric/nodes API, you can install NSX-T kernel modules manually from the hypervisor command line. Join the Hypervisor Hosts with the Management PlaneJoining the hypervisor hosts with the management plane ensures that the NSX Manager and the hosts can communicate with each other.
