This change violates this constraint. As a non-backward compatible change to the guest ABI I don't think you can change the default bus allocation method. You may find it more useful for your management plane to evenly distribute bus numbers for the (presumably) per-vNUMA node pcie-expander buses and explicitly specify the busNr for each. David
