You can't do that. There is no guest BIOS image for that machine type which knows how to read disk images and boot from them. So you must manually extract (or otherwise provide) a suitable kernel (and perhaps also initrd and dtb file) and pass them to QEMU, because QEMU's "built in bootloader" is very simple and just loads the kernel file and jumps to it. thanks -- PMM
