Or is a misuse of compats? Ah, that was the error (I could not really make sense of it). So, if I understand it correctly, ppi needs to be disabled for all virt machines. I think the correct way to do this would be to add the "compat" prop in virt_machine_class_init() (even if it is not strictly compat, as it always needs to be disabled). It can be removed there and added to a compat machine should support be added in the future. Or does anyone have a better idea?
