Sufficiently common cases can also be delegated to generic code: * Maximum number of CPUs Got that: QEMUMachine member max_cpus, main() enforces it. * Require -kernel Have a flag in QEMUMachine, enforce in main(). * Require certain drives Have QEMUMachine declare minimum and maximum number drives of each BlockInterfaceType?
