Before booting a compiled Linux kernel image on actual hardware, it can save us time and potential headache to do a quick boot in a virtual machine like QEMU. Also, QEMU has more flags than virtually any other binary I’ve ever seen (other than a google3 binary; shots fired), and simply getting it to print to the terminal is ¾ the battle.
