Change subject: core: Improve performance of updateAllDiskImageDynamicWithDiskIdByVmId ...................................................................... core: Improve performance of updateAllDiskImageDynamicWithDiskIdByVmId updateAllDiskImageDynamicWithDiskIdByVmId is running an update on the disk_image_dynamic table, using a subquery on the images table. Since images table does not have an index on image_group_id, and images can be a rather big table, this patch adds such an index.
