Bug Description
AFAIK, qed is better in performance than qcow2, so why we still use qcow2 for internal snapshots ? patch is trivial.

I'm not sure I follow, why qed is better? qed was an example/testing format in an attempt to make qcow2 faster. It succeeded in its task, and qcow2 has been improved a lot after playing with qed. What's wrong with qcow2 and why it is faster? How about providing some benchmarks?
