Clarify network topology — I.e. software bridges (variant A)
Prerequisites & cluster preparation(15 of 26)
Verified on SNO (single NIC). Some related tests may be marked not runnable.
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
RHEL VM images require a valid Red Hat pull secret. OpenShift Virtualization imports boot sources automatically into openshift-virtualization-os-images. An SSH key pair is also created and stored as an OpenShift Secret so VMs can be accessed with virtctl ssh.
1Check pull secret:
oc get secret pull-secret -n openshift-config (must include registry.redhat.io)2If missing: console.redhat.com → Downloads → download pull secret
oc set data secret/pull-secret -n openshift-config --from-file=.dockerconfigjson=~/pull-secret.json3If already present (normal — every OCP install requires one): export locally instead of re-downloading. Needed later for hcp create cluster --pull-secret ~/pull-secret.json (TC-HCP-002)
oc get secret/pull-secret -n openshift-config -o jsonpath='{.data.\.dockerconfigjson}' | base64 -d > ~/pull-secret.json4Check namespace openshift-virtualization-os-images and automatic boot-source imports
watch oc get dv -n openshift-virtualization-os-images (wait until all Succeeded)5If RHEL9 is not imported: create DataVolume manually (Commands/YAML tab)
6Create SSH key pair:
ssh-keygen -t ed25519 -f ~/.ssh/ocp-vm-key -N ''7Create namespace
vmtest if it does not exist: oc new-project vmtest (namespace and NADs are fully configured in PRE-08)8Store SSH key as OpenShift Secret (key name must be key — UI only shows secrets with key name key):
oc create secret generic vm-ssh-key -n vmtest --from-file=key=$HOME/.ssh/ocp-vm-key.pubCreate 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
Install Kasten K10 (Veeam) Operator and configure with MinIO
