// The size of the hard disk for the VM in megabytes.
// The builder uses expandable, not fixed-size virtual hard disks, so the

// is full. By default this is set to 40000 (about 40 GB).
DiskSize uint `mapstructure:"disk_size" required:"false"`
// The adapter type (or bus) that will be used
// by the cdrom device. This is chosen by default based on the disk adapter
// type. VMware tends to lean towards ide for the cdrom device unless
// sata is chosen for the disk adapter and so Packer attempts to mirror
// this logic. This field can be specified as either ide, sata, or scsi.
CdromAdapterType string `mapstructure:"cdrom_adapter_type" required:"false"`
// The guest OS type being installed. This will be
// set in the VMware VMX. By default this is other. By specifying a more
// specific OS type, VMware may perform some optimizations or virtual hardware
// changes to better support the operating system running in the
// virtual machine. Valid values differ by platform and version numbers, and may
// not match other VMware API's representation of the guest OS names. Consult your
// platform for valid values.
GuestOSType string `mapstructure:"guest_os_type" required:"false"`
// The [vmx hardware
// version](http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003746)
// for the new virtual machine. Only the default value has been tested, any
// other value is experimental. Default value is `9`.
Version string `mapstructure:"version" required:"false"`
// This is the name of the VMX file for the new virtual
// machine, without the file extension. By default this is packer-BUILDNAME,
// where "BUILDNAME" is the name of the build.
VMName string `mapstructure:"vm_name" required:"false"`
VMXDiskTemplatePath string `mapstructure:"vmx_disk_template_path"`
// Path to a [configuration template](/docs/templates/engine) that
// defines the contents of the virtual machine VMX file for VMware. The
// engine has access to the template variables `{{ .DiskNumber }}` and
// `{{ .DiskName }}`.
//
// This is for **advanced users only** as this can render the virtual machine
// non-functional. See below for more information. For basic VMX
// modifications, try `vmx_data` first.
