Summary

Shell script (setup_virt-cclm_env.sh) that prepares a freshly installed ACM environment (Hub + Spoke) for Fine-Grained RBAC, Fleet Virtualization, and Cross-Cluster Live Migration (CCLM) testing.

What the script does

1. Enable Tech Preview Features – Patch MCH to enable cnv-mtv-integrations-preview and fine-grained-rbac-preview. Auto-triggers MTV operator installation, User Management and Fleet Management perspectives.
2. Wait for CNV Deployment – Wait for openshift-cnv namespace and HyperConverged CR to be Available.
3. Configure CNV Feature Gates (Hub) – Enable decentralizedLiveMigration: true (requires CNV 4.20+).
4. Wait for virt-synchronization-controller – Verify controller pods are running (auto-deployed by CNV operator).
5. Create Sync Service – Create virt-synchronization-controller Service for Submariner connectivity (if Submariner deployed).
6. Enable MTV CCLM Feature Flag – Patch ForkliftController: feature_ocp_live_migration: true, restart forklift-controller pod.
7. Enable CCLM UI Feature Flag – Set kubevirtCrossClusterMigration: true in kubevirt-ui-features ConfigMap, restart kubevirt-console-plugin.
8. Verify Console Plugins – Confirm kubevirt-plugin and forklift-console-plugin are enabled.
9. Label local-cluster – Apply acm/cnv-operator-install=true (MTV Provider auto-creation) and environment=virtualization (acm-roles addon).
10. Label Spoke for CNV Installation – Apply acm/cnv-operator-install=true to trigger CNV addon deployment.
11. Verify Spoke CNV Configuration – Verify addon ManifestWork includes decentralizedLiveMigration: true and spoke HCO is managed by kubevirt-hyperconverged addon.
