[libvirt] libvirt Hyper-v 2012 r2 fix

[vikhyath reddy]

Update,

I tried adding root\virtualization\*v2 *to the namespace in libvirt source
code for hyperv. I ran some tests and it seems to work. I get the same
functionality (supported vs non-supported drivers) as hyper-v 2008.

Do you guys want me to submit the patch? If yes, what all do I need to
update to get the patch in?

Thanks,
Vik.
