Well, it depends how friendly you're feeling. Typically if the user has specified neither a -kernel nor some kind of flash image or BIOS, then we could just choose to start executing at address zero. This will probably either tear through a bunch of random garbage or end up looping endlessly through an exception vector. That's exactly what the hardware would do in that case, but the usual user response is to accuse QEMU of "hanging". -- PMM
