Hi all,
I was emulating kernel image and rootfs using qemu.
qemu -kernel vmlinuz-2.6.22.17-0.1-default -initrd test.cpio.gz /dev/ zero as mentioned in ramfs-rotfs documentation. every thing works fine. But i have some confusion here...
What is the role of /dev/zero.
anyone please explain..
Regards, Nabendu

I think i wanted to know "what is the role of /dev/zero here?"..in the qemu command..
qemu -kernel vmlinuz-2.6.22.17-0.1-default -initrd test.cpio.gz /dev/ zero
when i am not using /dev/zero qemu is executing and shutting down the run window..why thats so..

Qemu requires you to specify a hard disk to boot from. Obviously, if you load a kernel directly and have your root file system on a ramdisk, you don't need it. But you still have to specify it: Your emulated hda is /dev/zero - nothing.
Another approach would be to have a command line like:
qemu -kernel vmlinux-2.6 -initrd test.cpio.gz -hda /dev/zero
You could have read this in the Qemu documentation, too. It is mentioned there.
