Title:
  VMware: Sparse glance vmdk's size property is mistaken for capacity

Status in OpenStack Compute (nova):
  Fix Released
Status in VMwareAPI-Team:
  Confirmed

Bug description:
  Scenario:

  a sparse vmdk whose file size is 800MB and whose capacity is 4GB is uploaded to glance without specifying the size property.
  (glance uses the file's size for the size property in this case)

  nova boot with flavor tiny (root disk size of 1GB) said image.

  Result:
  The vmwareapi driver fails to spawn the VM because the ESX server throws a fault when asked to 'grow' the disk from 4GB to 1GB (driver thinks it is attempt to grow from 800MB to 1GB)

  Relevant hostd.log on ESX host:
  2013-10-15T17:02:24.509Z [35BDDB90 verbose 'Default'
  opID=HB-host-22@3170-d82e35d0-80] ha-license-manager:Validate -> Valid
  evaluation detected for "VMware ESX Server 5.0" (lastError=2,
  desc.IsValid:Yes)

  New capacity (2097152) is not greater than original capacity (8388608).

  I am still not exactly sure if this is consider user error on glance
  import, a glance shortcoming of not introspecting the vmdk, or a bug
  in the compute driver. Regardless, this bug is to track any potential
  defensive code we can add to the driver to better handle this
  scenario.
