[Qemu-devel] Is it possible to boot qemu-system-ppc with -kernel?

[Rob Landley]

I've been trying several variants of:

  qemu-system-ppc -M prep -nographic -hda "ext2.img" -kernel "zImage" \
    -append "rw init=/tools/bin/sh panic=1 PATH=/tools/bin root=/dev/hda
             console=/dev/ttyS0"

My miniconfig is attached.  (You can make a full-sized .config out of it with
"make allnoconfig KCONFIG_ALLSYMS=miniconfig-linux", I still need to get the 
miniconfig patch in so there's a better UI.)  I'm trying to boot the zImage 
file that produces.

Unfortunately, I've never managed to boot a ppc kernel under qemu 
with -kernel.  I've got to be doing something wrong, but I don't know what it 
is.  Could you offer any hints?

Here's the output I get:

It's not getting _to_ the kernel.  (I tried booting vmlinux instead of 
bzImage, but it made no difference.)

Thanks,
