I've been using QEMU 3.0.0 happily with -kernel bzImage from Linux v4.19. However, now I have another simulator (gem5) that boots from vmlinux, it would be convenient if I could boot both from the exact same vmlinux file. Is it possible with QEMU? Or alternatively, can you easily convert from vmlinux to bzImage somehow, without recompiling the kernel?
