BZ: 980771
9ae3a8
9ae3a8
For image formats that are not "QEMU native", but supported for
9ae3a8
compatibility, it is useful to verify that an image created with
9ae3a8
the 'gold standard' native tool can be read / written to successfully
9ae3a8
by QEMU.
9ae3a8
9ae3a8
In addition to testing non-native images, this could also be useful to
9ae3a8
test against image files created by older versions of QEMU.
9ae3a8
9ae3a8
This provides a directory to store small sample images, for use by
9ae3a8
scripts in tests/qemu-iotests.
9ae3a8
9ae3a8
Image files should be compressed with bzip2.
9ae3a8
9ae3a8
To use a sample image from a bash script, the _use_sample_img function
9ae3a8
will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to
9ae3a8
be the decompressed sample image copy.  To cleanup, call
9ae3a8
_cleanup_test_img as normal.

+This is for small sample images to be used with qemu-iotests, intended for
9ae3a8
+non-native formats that QEMU supports for compatibility.  The idea is to use
9ae3a8
+the native tool to create the sample image.
9ae3a8

9ae3a8
+For instance, a VHDX image in this directory would be an image created not by
