For image formats that are not "QEMU native", but supported for compatibility, it is useful to verify that an image created with the 'gold standard' native tool can be read / written to successfully by QEMU. In addition to testing non-native images, this could also be useful to test against image files created by older versions of QEMU. This provides a directory to store small sample images, for use by scripts in tests/qemu-iotests. Image files should be compressed with bzip2. To use a sample image from a bash script, the _use_sample_img function will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to be the decompressed sample image copy. To cleanup, call _cleanup_test_img as normal. Signed-off-by: Jeff Cody <jcody@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
