Yes, this seem very good. (to be honest, I didn't have used vmware since 4 years ;)
I like to see proxmox as a vmware competitor :)

ok, so we need child->parent to maintain the tree view.

So when we rollback, we need to update a value to know on which snapshot we are running.

Also need to update child->parent pointer when we delete an intermediate snapshot.

About zfs rollback, it seem to be the implementation of zfs which limit to work only on the last snapshot.
it's a main tree without branchs.
By default zfs can't rollback to previous snapshot if a more recent snapshot exist,so it thow an exception.
So it should be ok, user simply need to delete more recent snapshots before rollback.

For sheepdog, I have tell the question for rollback to the mailing list.

Yes, I guess users expect that functionality.
