YOU could have done the same...

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.
