A host-side overcommit value is set upon a physical node that implements virtual machines (VM Node). The overcommit value is determined by receiving a selected enablement template that includes a selected computing capacity and a selected overcommit value. A user-side normalization factor is determined that normalizes the selected computing capacity against a reference data handling system. A comparable computing capacity of the VM Node is determined. A host-side normalization factor is determined that normalizes the comparable computing capacity against the reference data handling system. The host-side overcommit value is determined from the selected overcommit value, the user-side normalization factor, and the host-side normalization factor. The host-side overcommit value may indicate the degree the comparable computing capacity is overcommitted to virtual machines deployed upon heterogeneous VM Nodes as normalized against the reference system.
