When creating a logical volume with virStorageVolCreateXMLFrom, "qemu-img convert" is called internally if clonevol is a file volume. Then, vol->target.format is used as output_fmt parameter but the target.format of logical volumes is always 0 because logical volumes haven't the volume format type element.
Fortunately, 0 was treated as RAW file format before commit f772b3d9, so there was no problem. But now, 0 is treated as the type of none, qemu-img fails with "Unknown file format 'none'".
This patch fixes this issue by treating output block devices as RAW file format like for input block devices.
