Verified on SNO (single NIC). Some related tests may be marked not runnable.

Cluster Health Check — Starting Point

Clarify network topology — I.e. software bridges (variant A)

Install and verify NMState Operator

Configure Linux bridges via NMState (Hetzner: variant A — software bridges)

Install OpenShift Virtualization Operator

Set up LVM Storage Operator — storage for VMs

Pull secret, import golden image, prepare SSH keys

Create namespace vmtest and NetworkAttachmentDefinitions

Install MetalLB Operator and configure IP pools (3 options)

MCE + HyperShift for hosted control planes

Deploy MinIO (S3 object storage)

Install MTV (Migration Toolkit for Virtualization) Operator

Install OADP Operator and configure with MinIO (S3)

Install Advanced Cluster Management (ACM) v2.17

Red Hat Advanced Cluster Management for Kubernetes v2.17 is the Kubernetes fleet manager for OpenShift. On an SNO cluster, ACM runs as the hub — in a real multi-cluster setup it would manage additional spoke clusters. For the PoC, the local SNO can be used as local-cluster (hub manages itself). ACM 2.17 adds fleet management features, governance policies, and observability.

1Step 1 — Install ACM Operator (RHACM) via OperatorHub

Ecosystem → Software Catalog → Operators → Advanced Cluster Management for Kubernetes

Channel: release-2.17, namespace: open-cluster-management

2Step 2 — Create MultiClusterHub CR (starts all ACM components). Set availabilityConfig to Basic for the test installation

3Step 3 — Wait until MultiClusterHub phase: Running (takes 5–10 min)

4Step 4 — Open ACM console: Infrastructure → Clusters

5Step 5 — Verify local-cluster: SNO manages itself

6Step 6 — Enable observability add-on (requires MinIO bucket from PRE-11; object-storage secret in Commands/YAML tab)

7Step 7 — Create MultiClusterObservability CR for Thanos/Grafana

Install Kasten K10 (Veeam) Operator and configure with MinIO
