Bug Description

The fix for: does two things:

a) disallows backing files

b) forces all images to raw format

The first is a serious security issue. The second helps with performance, but can lead to issues for deployers. It forces large disks when sparse images could offer huge space savings. It is especially problematic for deployments using older code that are trying to upgrade.

It makes sense to have a flag for b) s that some deployments can continue to use compressed and/or sparse images.

    Create a flag for force_to_raw for images

     * Allows for deployers to use compressed images if they prefer
     * Flag defaults to current behavior
     * Fixes bug 932180
     * Re-enables fetch_to_raw which was being skipped
     * Removes obsolete and broken method from libvirt
     * Checksumming will be re-enabled in a later patch
