[feature-request] Snapshots optimization: Do not merge if not necessary

Description (last modified by aeichner) (diff)

If I create several snapshots, then delete previous one, there is no need to merge.

like this: (both snapshots are offline, not Live)

+-snapshot01 |

+snapshot02 (changed VM settings, not VDIs)

Then I decided to delete snapshot01. Currently it tries to merge it with snapshot02, which takes time, but in reality in such cases it is much better to discard snapshot02 differencing VDI, and use differencing VDI of snapshot01 for snapshot02.

This is kind of implemented in the latest VirtualBox release. VBox determines the merge direction based on the size of the images to be merged. Your case should be really fast now. Closing as fixed for now.
