NACK. There is nothing inherently wrong with the source file not being
a qcow2 file. The whole point of creating a runtime snapshot is that
the original file (of _any_ format) becomes the backing file of a new
qcow2 file, so that the original file now serves as the snapshot.
Forbidding a live snapshot of a raw source file interferes with this intent.
