qemu linux kernel with busybox booting problem

[soumen acharya]

  Hi all,

   I was trying to boot linux kernel with qemu using custom busybox , having 
booting problem.

  I did the following :

  dd if=/dev/zero of=rootfs.img bs=1k count=2048
  mkfs.ext2 ­i 1024 ­F rootfs.img
  mkdir /mnt/rootfs
  mount ­o loop rootfs.img /mnt/rootfs
  rsync ­a busybox/_install/ /mnt/rootfs/
  chown ­R root:root /mnt/rootfs/
  sync
  qemu -­m 64 -­hda rootfs.img -­kernel linux­2.6.28.4/arch/x86/boot 
/bzImage -­append "root=/dev/hda"

while booting it shows:

VFS : can not open hda
      append proper root fs in "root="
      
Looking for inputs about how to do it correctly.

Thanks,
