Title:
  Hyper-V driver fails while creating instances on Windows / Hyper-V
  Server 2008 R2

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Creating an instance on a Hyper-V / Windows Server 2008 R2 compute
  node fails due to a WMI exception. This happens while creating
  creating and configuring the resources to be added to the VM.

  The resources already have set default values for certain properties, while other properties have NULL. Trying to set a new value over the NULL causes the exception:
  code:
  drive = self._get_new_resource_setting_data(res_sub_type)
  drive.Parent = ctrller_path

  exception:
