Detail: If source image is qcow2, and we want a qcow2 image, then doing a convert strips off compression and any snapshots the user had in that image. If a backing file exists, we stick with convert so we can pull in both the backing file and the COW image, otherwise we just cp the qcow2 file. This is also faster Signed-off-by: Marcus Sorensen <marcus@betterservers.com> 1354755241 -0700
