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 [10.60.1.93:7000, 10.60.1.92:7000, 10.60.1.94:7000] And I can't use the sheepdog now . Why this happened ?

So how the sheepdog create the increase images? 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 See also: http://wiki.qemu.org/Features/Sheepdog/Getting_Started Thanks, Kazutaka -------------- next part -------------- An HTML attachment was scrubbed...
