    # NOTE(sirp): There is some confusion around OVF. Here's a summary
    # of where we currently stand:
    #   1. OVF as a container format is misnamed. We really should be
    #      using OVA since that is the name for the container format;
    #      OVF is the standard applied to the manifest file contained
    #      within.
    #   2. We're currently uploading a vanilla tarball. In order to be
    #      OVF/OVA compliant, we'll need to embed a minimal OVF
    #      manifest as the first file.
