Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

https://bugzilla.redhat.com/show_bug.cgi?id=1091866 Add a new boolean 'sparse'. This will be used by the logical backend storage driver to determine whether the target volume is sparse or not (also known by a snapshot or thin logical volume). Although setting sparse to true at creation could be seen as duplicitous to setting during virStorageBackendLogicalMakeVol() in case there are ever other code paths between Create and FindLVs that need to know about the volume be sparse. Use the 'sparse' in a new virStorageBackendLogicalVolWipe() to decide whether to attempt to wipe the logical volume or not. For now, I have found no means to wipe the volume without writing to it. Writing to the sparse volume causes it to be filled. A sparse logical volume is not completely writeable as there exists metadata which if overwritten will cause the sparse lv to go INACTIVE which means pool-refresh will not find it. Access to whatever lvm uses to manage data blocks is not provided by any API I could find. |

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.
