Title:
  vmware driver races to create instance images

Status in OpenStack Compute (Nova):
  In Progress
Status in The OpenStack VMwareAPI subTeam:
  In Progress

Bug description:
  Change Ia0ebd674345734e7cfa31ccd400fdba93646c554 traded one race
  condition for another. By ignoring all mkdir() calls that would
  otherwise fail because an instance directory already exists, two nodes
  racing to create a single image will corrupt or lose data, or fail in
  a strange way. This call should fail in that case, but doesn't after
  the recent patch was merged:

  https://github.com/openstack/nova/blob/master/nova/virt/vmwareapi/vmops.py#L350
