We could, but i think this would hurt usability. I suggest that when the user chooses a configuration, he/she expects to get something particular. And IMHO it's much better to default to GICv2 (to be backwards-compatible), and just report error in case if this is not supported by KVM, than to default to something, which is different on different machines and different kernels. Libvirt guys already blame "virt" machine for being too flexible... Kind regards, Pavel Fedin Expert Engineer Samsung Electronics Research center Russia
