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.

Charles Duffy cc76cf31d7 support lzop save compression for qemu
Per prior discussion -- this was, indeed, trivial.

I'm a little disappointed to be breaking the ordering characteristics of
the enum (as it had been ordered by increasing time requirements and
decreasing output size), but breaking any save files with the old
constants in the headers would of course be worse.

Subject: [PATCH] support lzop save compression for qemu

One of the larger disincentives towards use of compression for migrated-out save
files is performance impact. This patch adds support for lzop; CPU time for
compression is about 5x faster than gzip (the next most performant algorithm)
and decompression is about 3x faster.

         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.
