Title:
  VMware driver: unused cached images never clear from datastore's cache
  folder (usually named vmware_base)

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  customer reports that that even when they no longer have a VM in their
  vCenter inventory using a particular image, they are unable to delete
  the vmdk corrsponding to that image in the vmware_base directory.

  Note, the true problem here is that if one cycles through a lot of
  different images in your deployment, these images are not cleared from
  the datastore "cache" in any automatic fashion.  This issue was
  encountered when someone tried to perform this task manually using
  vCenter client.  They got the error: “cannot delete file <filename>”
