No errors were found on the image.

Data file required, but without data file name in the image:

Setting data-file for an image with internal data:

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.
