This is somewhat confusing, but long ago the decision was made that booting from an ISO image should use the ISO as a root drive. This means that it is only really useful for things like live cds. I believe you could use the new block device mapping code to create an instance that boots from an iso and has an ephemeral drive as well but I haven’t tested this.
