Thanks, But I don't understand how It can work.

If I 
"I create a base vdi : image1 
create a snapshot: snap1 
create a snapshot: snap2 
now I boot on snap1 
qemu sheepdog:image1:snap1 
I write datas
and now I restart the vm (so with qemu sheepdog:image1:snap1).
"
It will rollback ? But in this case It will destroy my new datas ?
In this case I don't want rollback, I just want restart the vm.

If you run the following command, you can rollback the snapshot again. 

$ qemu sheepdog:image1:snap1 

I think the 'collie vdi tree' command would help you.
