BZ: 980771
218e99
218e99
For image formats that are not "QEMU native", but supported for
218e99
compatibility, it is useful to verify that an image created with
218e99
the 'gold standard' native tool can be read / written to successfully
218e99
by QEMU.
218e99
218e99
In addition to testing non-native images, this could also be useful to
218e99
test against image files created by older versions of QEMU.
218e99
218e99
This provides a directory to store small sample images, for use by
218e99
scripts in tests/qemu-iotests.
218e99
218e99
Image files should be compressed with bzip2.
218e99
218e99
To use a sample image from a bash script, the _use_sample_img function
218e99
will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to
218e99
be the decompressed sample image copy.  To cleanup, call
218e99
_cleanup_test_img as normal.

+This is for small sample images to be used with qemu-iotests, intended for
218e99
+non-native formats that QEMU supports for compatibility.  The idea is to use
218e99
+the native tool to create the sample image.
218e99
+
218e99
+For instance, a VHDX image in this directory would be an image created not by
218e99
+QEMU itself, but rather created by Hyper-V.

218e99
+Sample images added here must be compressed with bzip2.
