The mapping operation of large disks especially ones stored over a long chain of QCOW2 files can take a long time to finish. Additionally when mapping fails there was no way recover by restarting the mapping from the failed location. The new options, --start-offset and --max-length allows the user to divide these type of map operations into shorter independent tasks.
