You can use qemu-img info to check the image format.

qemu-img info image-qcow.qcow2

the result will be something like this

image: image-qcow.qcow2
file format: qcow2
virtual size: 10G (10737418240 bytes)
disk size: 136K
cluster_size: 65536

After that, if you want to get the file format you can parse the output to get it.

Hope this helps
