Domain listing, basic information retrieval and domain life cycle
management is implemented. But currently the domian XML output
lacks the complete devices section.
The driver uses OpenWSMAN to directly communicate with an Hyper-V
server over its WS-Management interface exposed via Microsoft WinRM.
The driver is based on the work of Michael Sievers. This started in
the same master program project group at the University of Paderborn
as the ESX driver.
See Michael's blog for details: http://hyperv4libvirt.wordpress.com/
