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.

Peter Krempa 42619ed05d qemu: copy: Accept 'format' parameter when copying to a non-existing img
We have the following matrix of possible arguments handled by the logic
statement touched by this patch:
       | flags & _REUSE_EXT | !(flags & _REUSE_EXT)
-------+--------------------+----------------------
 format| (1)                | (2)
-------+--------------------+----------------------
!format| (3)                | (4)
-------+--------------------+----------------------

In cases 1 and 2 the user provided a format, in cases 3 and 4 not. The
user requests to use a pre-existing image in 1 and 3 and libvirt will
create a new image in 2 and 4.

The difference between cases 3 and 4 is that for 3 the format is probed
from the user-provided image, whereas in 4 we just use the existing disk
format.

The current code would treat cases 1,3 and 4 correctly but in case 2 the
format provided by the user would be ignored.

The particular piece of code was broken in commit 35c7701c64
but since it was introduced a few commits before that it was never
released as working.

         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.
