Re: RE: [Qemu-devel] Kernel panic - not syncing: No init found.

[Clemens Kolbitsch]

are you passing an initrd to qemu?

i call qemu like this:

qemu \
        -hda image \
        -boot c \
        -net user \
        -net nic,vlan=0,model=rtl8139 \
        -initrd initrd \
        -append "root=/dev/hda1" \
        -kernel kernel \
        -no-kqemu

whereas kernel is a link to the bzImage and initrd links to a file i have 
created inside qemu using mkinitramfs

I can't find the initramfs file. When I use locate initramfs I can find some initramfs files, but none in the directory where I work in.

you need to generate this file.

may I suggest something (while I do it in parallel) ?

please download detaolb_v06.iso and extract the "debug" file at the
root of the iso.
This is a static initramfs file. Use it this way:

qemu -L bios -hda hda -kernel vmlinux -initrd debug

you can find the iso at http://detaolb.sf.net

On my side, I'll compile linux 2.6.18.1 with your config file and test
it over here...
