The NFS driver uses qcow2 images with backing files to represent volume snapshots, which is not allowed for qcow2 disk images downloaded from glance. The driver uses cinder.image_utils to convert a qcow2 snapshot to a raw volume; this was not a problem for the first snapshot, whose backing file is raw, and hence passed the image format inspector, but the second snapshot has a qcow2 backing file, which the image_utils were rejecting as a security risk. Thus we now pass the qemu_img_info from the backing image as an additional parameter to the image convert call, which indicates that the file has already been screened and allows the conversion to occur.
