• iso_checksum (string) - The checksum for the ISO file or virtual hard drive file. The algorithm to use when computing the checksum can be optionally specified with iso_checksum_type. When iso_checksum_type is not set packer will guess the checksumming type based on iso_checksum length. iso_checksum can be also be a file or an URL, in which case iso_checksum_type must be set to file; the go-getter will download it and use the first hash found.

• iso_url (string) - A URL to the ISO containing the installation image or virtual hard drive (VHD or VHDX) file to clone.
