// The number of cpus to use when building the VM.
CpuCount int `mapstructure:"cpus" required:"false"`

MemorySize int `mapstructure:"memory" required:"false"`
// The number of cores per socket to use when building the VM. This

CoreCount int `mapstructure:"cores" required:"false"`
// This is the network type that the virtual machine will be created with.
// This can be one of the generic values that map to a device such as
// hostonly, nat, or bridged. If the network is not one of these values,
// then it is assumed to be a VMware network device. (VMnet0..x)
Network string `mapstructure:"network" required:"false"`
// This is the ethernet adapter type the the virtual machine will be
// created with. By default the `e1000` network adapter type will be used
// by Packer. For more information, please consult [Choosing a network
// adapter for your virtual
// machine](https://kb.vmware.com/s/article/1001805) for desktop VMware
// clients. For ESXi, refer to the proper ESXi documentation.
NetworkAdapterType string `mapstructure:"network_adapter_type" required:"false"`
// Specify whether to enable VMware's virtual soundcard device when
// building the VM. Defaults to false.
Sound bool `mapstructure:"sound" required:"false"`
// Enable VMware's USB bus when building the guest VM. Defaults to false.
// To enable usage of the XHCI bus for USB 3 (5 Gbit/s), one can use the
// vmx_data option to enable it by specifying true for the usb_xhci.present
// property.
USB bool `mapstructure:"usb" required:"false"`
// This specifies a serial port to add to the VM. It has a format of
// `Type:option1,option2,...`. The field `Type` can be one of the following
// values: `FILE`, `DEVICE`, `PIPE`, `AUTO`, or `NONE`.
//
// * `FILE:path(,yield)` - Specifies the path to the local file to be used
// as the serial port.
//
// * `yield` (bool) - This is an optional boolean that specifies
// whether the vm should yield the cpu when polling the port. By
// default, the builder will assume this as `FALSE`.
//
// * `DEVICE:path(,yield)` - Specifies the path to the local device to be
//  used as the serial port. If `path` is empty, then default to the first
// serial port.
//
// * `yield` (bool) - This is an optional boolean that specifies
// whether the vm should yield the cpu when polling the port. By
// default, the builder will assume this as `FALSE`.
//
// * `PIPE:path,endpoint,host(,yield)` - Specifies to use the named-pipe
// "path" as a serial port. This has a few options that determine how the
// VM should use the named-pipe.
//
// * `endpoint` (string) - Chooses the type of the VM-end, which can be
// either a `client` or `server`.
//
// * `host` (string) - Chooses the type of the host-end, which can
// be either `app` (application) or `vm` (another virtual-machine).
//
// * `yield` (bool) - This is an optional boolean that specifies
// whether the vm should yield the cpu when polling the port. By
// default, the builder will assume this as `FALSE`.
//
// * `AUTO:(yield)` - Specifies to use auto-detection to determine the
// serial port to use. This has one option to determine how the VM should
// support the serial port.
//
// * `yield` (bool) - This is an optional boolean that specifies
// whether the vm should yield the cpu when polling the port. By
// default, the builder will assume this as `FALSE`.
//
// * `NONE` - Specifies to not use a serial port. (default)
//
Serial string `mapstructure:"serial" required:"false"`
// This specifies a parallel port to add to the VM. It has the format of
// `Type:option1,option2,...`. Type can be one of the following values:
// `FILE`, `DEVICE`, `AUTO`, or `NONE`.
//
// * `FILE:path` - Specifies the path to the local file to be used
// for the parallel port.
//
// * `DEVICE:path` - Specifies the path to the local device to be used
// for the parallel port.
//
// * `AUTO:direction` - Specifies to use auto-detection to determine the
// parallel port. Direction can be `BI` to specify bidirectional
// communication or `UNI` to specify unidirectional communication.
//
// * `NONE` - Specifies to not use a parallel port. (default)
Parallel string `mapstructure:"parallel" required:"false"`
