Title:
  Hyper-v fails to attach volumes when using v1 volume utilites

Status in OpenStack Compute (Nova):
  Fix Committed
Status in OpenStack Compute (nova) icehouse series:
  In Progress

Bug description:
  The following patch
  https://github.com/openstack/nova/commit/4c2f36bfe006cb0ef89ca7a706223f30488a182e
  #diff-5c6ee11140977e63b54542e2ff5763d3R22 caused a regression by
  changing the eventlet.subprocess.Popen with the builtin
  subprocess.Popen (by using the nova.utils execute method) without
  changing the way the args were parsed.

  In this module, the execution args were parsed separated by
  whitespaces, which is not allowed by the builtin subprocess.Popen,
  causing a "not found" error. This error is returned for example when
  attaching a volume, at the point where iscsicli tool is used to login
  the iSCSI target or portal.
