Hi Dimitri, We are moving the community to the new forum by the end of the week [1]. This last week things are getting even worse with the hosting company... seems a good time to move on ;)
Anyway there are two drivers DS and TM. QoW is used for TM when a persistent image (or master/golden) is cloned to fire a new VM. The original image is moved to used state and so it won't be deleted. On the other hand, a DS clone operation creates a completely (read independent from) the original image. Using QoW for this would be faster, but we will need more logic to flatten the snapshots when the original is deleted, and potentially we will end up with multiple snapshot layers that will degrade performance.
