Part 2 of a series on deploying hosted control planes with OpenShift Virtualization, covering the 'split hub' topology where Red Hat Advanced Cluster Management (Cluster A) is separated from the multicluster engine for Kubernetes, hosted control plane, and OpenShift Virtualization (Cluster B). The guide walks through hardware sizing, LVM storage configuration, MetalLB setup, operator installation, and creating a hosted cluster using the hcp CLI with KubeVirt. It explains why enterprises prefer this model for independent scaling, separation of duties, and clean operational boundaries, and concludes with pros/cons of the topology before previewing a three-cluster split in Part 3.
