Do you know how to install grub on a raw device file?If I recall correctly, qemu can boot a linux kernel directly so you *probably* don't need grub.
Aha! I completely forgot about those options. This works great:sudo qemu -kernel-kqemu -kernel newtest.mount/boot/vmlinuz-2.6.18-6-486 -append "root=/dev/hda1 ro" -initrd newtest.mount/boot/initrd.img-2.6.18-6-486 newtest.raw
It makes the command line a bit awkward, but does the trick. This is great workaround, thanks!
That said, if possible, I'd still like to get grub installed to make it self-contained and boot up like normal (else I need to update all the startup scripts to be aware of the exact kernel version).
One way would be to boot the VM with the above trick and then install grub from the inside... but there's *got* to be a way to install it from the outside, straight into the raw image.
Joey's idea of grub-mkdevicemap sounds good; I'll need to look into that more.
Thanks everyone for all the help! -david
