Allon Mureinik has submitted this change and it was merged. Change subject: core: Don't clone Guids in VDS.clone() ...................................................................... core: Don't clone Guids in VDS.clone() Since Guids are immutable, there is no need for VDS.clone() to create new Guid instances, especially not by the expensive string-parsing method. This patch changes the new instance created by VDS.clone() to simply hold references to the old one's Guid, thus improving performance. As a nice side bonus, this will allow cloning of VDS instances that have null VDS group or storage pool IDs. This patch also contains a test to assert this functionality.
