// The size, in megabytes, of the hard disk to create for the VM. By
// default, this is 40000 (about 40 GB).
DiskSize uint `mapstructure:"disk_size" required:"false"`
// The method by which guest additions are made available to the guest for
// installation. Valid options are upload, attach, or disable. If the mode
// is attach the guest additions ISO will be attached as a CD device to the
// virtual machine. If the mode is upload the guest additions ISO will be
// uploaded to the path specified by guest_additions_path. The default
// value is upload. If disable is used, guest additions won't be
// downloaded, either.
GuestAdditionsMode string `mapstructure:"guest_additions_mode" required:"false"`
// The path on the guest virtual machine where the VirtualBox guest
// additions ISO will be uploaded. By default this is
// VBoxGuestAdditions.iso which should upload into the login directory of
// the user. This is a configuration template where the Version variable is
// replaced with the VirtualBox version.
GuestAdditionsPath string `mapstructure:"guest_additions_path" required:"false"`
// The SHA256 checksum of the guest additions ISO that will be uploaded to
// the guest VM. By default the checksums will be downloaded from the
// VirtualBox website, so this only needs to be set if you want to be
// explicit about the checksum.
GuestAdditionsSHA256 string `mapstructure:"guest_additions_sha256" required:"false"`
// The URL to the guest additions ISO to upload. This can also be a file
// URL if the ISO is at a local path. By default, the VirtualBox builder
// will attempt to find the guest additions ISO on the local file system.
// If it is not available locally, the builder will download the proper
// guest additions ISO from the internet.
GuestAdditionsURL string `mapstructure:"guest_additions_url" required:"false"`
// The interface type to use to mount guest additions when
// guest_additions_mode is set to attach. Will default to the value set in
// iso_interface, if iso_interface is set. Will default to "ide", if
// iso_interface is not set. Options are "ide" and "sata".
GuestAdditionsInterface string `mapstructure:"guest_additions_interface" required:"false"`
// The guest OS type being installed. By default this is other, but you can
// get dramatic performance improvements by setting this to the proper
// value. To view all available values for this run VBoxManage list
// ostypes. Setting the correct value hints to VirtualBox how to optimize
// the virtual hardware to work best with that operating system.
GuestOSType string `mapstructure:"guest_os_type" required:"false"`
// When this value is set to true, a VDI image will be shrunk in response
// to the trim command from the guest OS. The size of the cleared area must
// be at least 1MB. Also set hard_drive_nonrotational to true to enable
// TRIM support.
HardDriveDiscard bool `mapstructure:"hard_drive_discard" required:"false"`
// The type of controller that the primary hard drive is attached to,
// defaults to ide. When set to sata, the drive is attached to an AHCI SATA
// controller. When set to scsi, the drive is attached to an LsiLogic SCSI
// controller.
HardDriveInterface string `mapstructure:"hard_drive_interface" required:"false"`
// The number of ports available on any SATA controller created, defaults
// to 1. VirtualBox supports up to 30 ports on a maximum of 1 SATA
// controller. Increasing this value can be useful if you want to attach
// additional drives.
SATAPortCount int `mapstructure:"sata_port_count" required:"false"`
// Forces some guests (i.e. Windows 7+) to treat disks as SSDs and stops
// them from performing disk fragmentation. Also set hard_drive_discard to
// true to enable TRIM support.
HardDriveNonrotational bool `mapstructure:"hard_drive_nonrotational" required:"false"`
// The type of controller that the ISO is attached to, defaults to ide.
// When set to sata, the drive is attached to an AHCI SATA controller.
ISOInterface string `mapstructure:"iso_interface" required:"false"`
// Set this to true if you would like to keep the VM registered with
// virtualbox. Defaults to false.
KeepRegistered bool `mapstructure:"keep_registered" required:"false"`
// Defaults to false. When enabled, Packer will not export the VM. Useful
// if the build output is not the resultant image, but created inside the
// VM.
SkipExport bool `mapstructure:"skip_export" required:"false"`
// This is the name of the OVF 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"`
