util: storage: Improve error message when requesting image above 'start'
When a user would specify a backing chain index that is above the start point libvirt would report a rather unhelpful error: invalid argument: could not find backing store 1 in chain for 'sub/link2' This patch adds an explicit check that the index is below start point in the backing store and reports the following error if not: invalid argument: requested backing store index 1 is above 'sub/../qcow2' in chain for 'sub/link2' Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1177062
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.

virtualization technologies provided by many operating systems. It
