Title:
  VMwareVCDriver: Sparse disk copy error on spawn

Status in OpenStack Compute (Nova):
  Fix Released
Status in The OpenStack VMwareAPI subTeam:
  Fix Committed

Bug description:
  Not sure if this is a real bug, or just a case of inadequate
  documentation combining with bad error reporting.  I get an exception
  (below) when booting a VM.  The exception happens after glance is done
  streaming the disk image to VC (i.e., I see the image in the
  vmware_source folder in the DataSource) and it prevents the VM from
  actually booting.

  I tried two different ways of adding the image to glance (both as
  'ovf' and as 'bare') neither of which seemed to make a difference:

  glance add name="Ubuntu-ovf" disk_format=vmdk container_format=ovf
  is_public=true vmware_adaptertype="lsiLogic"
  vmware_ostype="ubuntuGuest" vmware_disktype="sparse" <
  ~/ubuntu12.04-sparse.vmdk

  glance add name="Ubuntu-bare" disk_format=vmdk container_format=bare
  is_public=true vmware_adaptertype="lsiLogic"
  vmware_ostype="ubuntuGuest" vmware_disktype="sparse" <
  ~/ubuntu12.04-sparse.vmdk

  In both cases, I see this exception (note: there actually seems to be
  a second exception to, perhaps due to inproper error handling with the
  first):
