Multicluster Engine (MCE) is required for all HCP tests.
Important — pod capacity per node (not just CPU/RAM): By default a cluster is installed with a maximum of 250 pods per node. A hosted cluster adds roughly 30–40 extra pods plus 2+ worker VM pods (virt-launcher). On an SNO that is both control plane and worker, the node-wide pod limit (Too many pods) can be hit before CPU or RAM runs out. Before HCP tests, check: oc describe $(oc get nodes -o name) | grep 'Non-terminated Pods' and raise the pod limit if necessary.
NOTE: The MCE operator is installed automatically when you install Advanced Cluster Management (PRE-14). If PRE-14 is already complete, verify the MultiClusterEngine CR instead of reinstalling the operator.
