=== Create and open image with external data file ===

With data file name in the image:
Formatting 'TEST_DIR/t.IMGFMT', fmt=IMGFMT size=67108864 data_file=TEST_DIR/t.IMGFMT.data
No errors were found on the image.

Setting data-file for an image with internal data:
Formatting 'TEST_DIR/t.IMGFMT', fmt=IMGFMT size=67108864
qemu-io: can't open device TEST_DIR/t.qcow2: 'data-file' can only be set for images with an external data file

=== Conflicting features ===

Convert to compressed target with data file:
Formatting 'TEST_DIR/t.IMGFMT.src', fmt=IMGFMT size=67108864
wrote 1048576/1048576 bytes at offset 0
1 MiB, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec)
qemu-img: error while writing at byte 0: Operation not supported

Convert uncompressed, then write compressed data manually:
Images are identical.
write failed: Operation not supported
No errors were found on the image.

Take an internal snapshot:
qemu-img: Could not create snapshot 'test': -95 (Operation not supported)
No errors were found on the image.

=== Standalone image with external data file (efficient) ===
