==== Expanding the cluster with Virtual Media on the baremetal network
In {product-title} {product-version}, you can expand an installer provisioned cluster deployed using the `provisioning` network by using Virtual Media on the `baremetal` network. You can use this feature when the `ProvisioningNetwork` configuration setting is set to `Managed`. To use this feature, you must set the `virtualMediaViaExternalNetwork` configuration setting to `true` in the `provisioning` custom resource (CR). You must also edit the machineset to use the API VIP address. See xref:../installing/installing_bare_metal_ipi/ipi-install-expanding-the-cluster.html#preparing-to-deploy-with-virtual-media-on-the-baremetal-network_ipi-install-expanding[Preparing to deploy with Virtual Media on the baremetal network] for details.

==== MetalLB load balancer
This release introduces the MetalLB Operator. After installing and configuring the MetalLB Operator, you can deploy MetalLB to provide a native load balancer implementation for services on bare-metal clusters. Other on-premise infrastructures that are like bare metal can also benefit.
The Operator introduces a custom resource, `AddressPool`. You configure address pools with ranges of IP addresses that MetalLB can assign to services. When you add a service of type `LoadBalancer`, MetalLB assigns an IP address from a pool.
For this release, Red Hat only supports using MetalLB in layer 2 mode.
For more information, see xref:../networking/metallb/about-metallb.adoc#about-metallb[About MetalLB and the MetalLB Operator].
