Thanks your reply!

I'll try it again.

Some other questions:
1,The base image need to be a snapshot ?  Why can't be a raw image?
   For local disk images ,The following commands worked well:
   $ qemu-img -b debian-base.img -f qcow2 debian_inc.img

2, I have do somethings and I found the following output:
[root at sim92 store_dir]# collie cluster info
Waiting for other nodes joining
Ctime                Epoch Nodes
2011-01-11 14:07:26     12 [,,]

And I can't use the sheepdog now . Why this happened ?

Thanks you very much !

A snapshot tag is missing for the base image, and you can use only a
raw format for Sheepdog.

Try the followings:
 1. Create a base image
      $ qemu-img convert ./image.raw sheepdog:debian
 2. Take a snapshot to use as a base image
      $ qemu-img snapshot -c base sheepdog:debian
 3. Create a cloned image from sheepdog:debian:base
      $ qemu-img create -b sheepdog:debian:base sheepdog:debian_inc
