Tal Nisan has submitted this change and it was merged. Change subject: core: CloneImageGroupVolumesStructure - determineSourceImageGroup() ...................................................................... core: CloneImageGroupVolumesStructure - determineSourceImageGroup() This patch changes the determineSourceImageGroup() method - 1. removes wrong equality by reference which was almost never true. 2. reduces an sql query, if both the parent and the template image were Guid.Empty a db query was performed and a Guid.Empty was used as the image group id, we can save that query.
