This is for small sample images to be used with qemu-iotests, intended for
non-native formats that QEMU supports for compatibility. The idea is to use
the native tool to create the sample image.
For instance, a VHDX image in this directory would be an image created not by
QEMU itself, but rather created by Hyper-V.
Sample images added here must be compressed with bzip2.
