Load Linux bzImage in QEMU?

Question

I compiled a Linux by doing make menuconfig then make and now I have compiled the most recent version of Linux. How can I load the kernel into QEMU?

Here is a fully automated QEMU + Buildroot setup that just works: https://github.com/cirosantilli/linux-kernel-module-cheat — Ciro Santilli OurBigBook.com, Nov 20 '18 at 11:22

From qemu's help:

Linux/Multiboot boot specific:
-kernel bzImage use 'bzImage' as kernel image
-append cmdline use 'cmdline' as kernel command line
-initrd file    use 'file' as initial ram disk
-dtb    file    use 'file' as device tree image

A quick test here using Arch's kernel/initrd (qemu -kernel /boot/vmlinuz-linux -initrd /boot/initramfs-linux.img) worked (dropped me into a recovery shell since I didn't provide a root device).

could I just do qemu -kernel linux/arch/x86/boot/bzimage? – Coder404 Sep 09 '12 at 15:06
