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. Signed-off-by: Atsushi Kumagai <kumagai-atsushi@mxc.nes.nec.co.jp>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
