Title:
  Hyper-V: cannot attach volumes from local HA shares

Status in compute-hyperv:
  Fix Released
Status in OpenStack Compute (nova):
  Fix Released
Status in os-win:
  Fix Released

Bug description:
  At the moment, the Hyper-V driver uses the UNC path of images stored
  on SMB shares, regardless if the share is remote or not. Citing from
  the MS documentation, this is not supported:

  “Accessing a continuously available file share as a loopback share is
  not supported. For example, if Microsoft SQL Server or Hyper-V store
  data files on SMB file shares, they must run on computers that are not
  a member of the file server cluster for the SMB file shares.”

  This is troublesome for the Hyper-C scenario, as Hyper-V will attempt
  to modify the image ACLs, making them unusable. The easy fix is to
  simply check if the share is local, and use the local path in that
  case.
