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.

If the debugging is enabled, the virCommand subsystem catches debug
messages in the command output as well. In that case, we can't assume
the string corresponding to command's stdout will start with specific
prefix. But the prefix can be moved deeper in the string. This bug
shows itself when parsing dnsmasq output:
2012-12-06 11:18:11.445+0000: 18491: error :
dnsmasqCapsSetFromBuffer:664 : internal error cannot parse
/usr/sbin/dnsmasq version number in '2012-12-06 11:11:02.232+0000:
18492: debug : virFileClose:72 : Closed fd 22'
We can clearly see that the output of dnsmasq --version
doesn't start with expected "Dnsmasq version " string but a libvirt
debug output.

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.
