From c0469496b32910a6a092d5b614efbf4088b13a29 Mon Sep 17 00:00:00 2001 From: Eyal Moscovici Date: Wed, 13 May 2020 16:36:29 +0300 Subject: qemu-img: Add --start-offset and --max-length to map 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.
