[libvirt] [PATCH] Hyper-V 2012 R2 support

Hi,
This patch adds support to libvirt to work with Hyper-V 2012 R2. This
will however mean
that Hyper-V 2008 will no longer be supported. Microsoft supports
hyperv 2008 management
via windows 7 and hyperv 2012 via windows 8.1 (note that the reverse
is not true, that is,
win 7 cannot manage hyperv 2012 and win 8.1 cannot manage hyperv
2008). I think they wanted
to keep the application code separate, in the sense that one manages
the old namespace and
the new one manages the new v2 namespace. The difference between the
two namespaces is not great
either, sadly, both of them have same class names but with different
field types (int, string etc.)
which have been separated by the namespace root/virtualization vs
root/virtualization/v2
For users who wish to use libvirt to manage Hyper-V 2008, using an
older version of libvirt <= 1.4.2 should work.
Since new Hyper-V 2008 drivers wont be contributed to libvirt anyway,
so it is not like the users will be missing on features.
And it is more likely that all future contributions to libvirt will be
on Hyper-V 2012 R2 and beyond.
