OVN-Kubernetes is OpenShift 4.22's default CNI. Why keep it instead of Cilium or Calico, and when a certified vendor plugin is still the right call on 4.22.

Disk types, IOPS, and throughput OpenShift needs for etcd, ODF, and CSI on bare metal, vSphere, AWS, Azure, and IBM Cloud—and which setups fail in production.

Broadcom has gated VMware VDDK downloads behind TAP and entitlements. How that change hits MTV migrations to OpenShift Virtualization—and what to do instead.

Install LokiStack and the Network Observability Operator on OpenShift 4.22, then use FlowCollector for eBPF flows, Topology, and traffic troubleshooting.

How to start an on-prem OpenShift PoC: pick a single cluster or a fleet hub, finish DNS and firewall first, then use Assisted Installer and day-2 operators.

When OpenShift GitOps should feed RHACM policies instead of applying CRs to every cluster, and when a field framework like AutoShift is the example—not the SKU.

How AI agents, OpenShift Lightspeed, and Ansible can automate MTV migrations from vSphere to OpenShift Virtualization—assessment, waves, and troubleshooting.

When Karpenter should own ROSA HCP compute versus machine pools, how it coexists with Cluster Autoscaler, and what self-managed OpenShift uses instead.

Why RHACM 2.16 is the fleet hub for OpenShift Virtualization across clusters: inventory, Observability, policy-driven backup, live migration, and VM RBAC.

How NetworkPolicy, AdminNetworkPolicy, and MultiNetworkPolicy fit on OpenShift 4.22: who owns each control plane, evaluation order, and VM secondary nets.
