The QEMU project is currently considering to move its bug tracking to another
system. For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state
back to "New" within the next 60 days, otherwise this report will be marked as
"Expired". Or mark it as "Fix Released" if the problem has been solved with a
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
Qemu refuses to multiboot Elf64 kernels
Status in QEMU:
Incomplete
Bug description:
Qemu does not multiboot Elf64 bit kernels when emulating x86_64
systems. This is unfortunate because it renders the `-kernel` option
quite useless. It's true that a multiboot compatible bootloader puts
you in protected mode by default, and you have to set up the long mode
yourself. While it is easy to put such 32-bit bootstrap code in a 64
bit binary, it is not possible to compile a 64 bit kernel into a 32
bit binary.
After quick search, it turned out that loading 64 bit elf binaries has
been disabled to be compatible with GRUB. However, since that time,
both GRUB and Syslinux load 64 bit ELF kernels just fine, which makes
qemu incompatible with them. Furthermore, it seems that this feature
does and has always worked fine and that people have since submitted
patches to re-enable it.

Please consider applying the attached patch.
