[Qemu-devel] booting demo kernel with -kernel <demo kernel>

[Toan Pham]

Hi,

Qemu has been a great tool to boot the linux kernel using a parameter
like below.  However, I have now been experiencing with os-development
and noticed that qemu can not boot a demo kernel that is compiled as
elf format and reallocated to 0x100000.  One example is a demo kernel
found as osdev.org.  I am not sure why qemu bootloader is not tailored
to boot this fundamental kernel format since it would be very
convenience for many OS enthusiasts.  Is it something you can consider
add support on feature releases?  thanks.


example 1:  can not boot demo kernel

qemu -kernel <demo_kernel.bin> -hda /dev/zero


example 2:  same command, boot the linux kernel alright!

qemu -kernel <linux_kernel.bzImage format> -hda /dev/zero


-thank you
