To create a new cluster network using the Harvester UI, navigate to Networks > Cluster Network Configuration.

Use the Create a Cluster Network option to create the new cluster network. E.g., name it cluznet.

Once the network is created, configure its uplink NIC via the Create Network Configuration option.

To configure the uplink link, a new NIC device must be made available to the Harvester host by performing the following steps using the Linux VMM:

• create a new virtual network
• use the new virtual network as the source of the NIC
