Different protocols have different means to uniquely identify a storage file. This patch implements a storage driver API to retrieve a unique string describing a volume. The current implementation works for local storage only and returns the canonical path of the volume. To add caching support the local filesystem driver now has a private structure holding the cached string, which is created only when it's initially accessed. This patch provides the implementation for local files only for start.
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.
