From a0cf8daf77548786ced84d773f06fc70571c5d38 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 11 Feb 2020 10:49:00 +0100 Subject: iotests: Test copy offloading with external data file This adds a test for 'qemu-img convert' with copy offloading where the target image has an external data file. If the test hosts supports it, it tests both the case where copy offloading is supported and the case where it isn't (otherwise we just test unsupported twice). More specifically, the case with unsupported copy offloading tests qcow2_alloc_cluster_abort() with external data files.
