# VZVirtioSocketDeviceConfiguration

A configuration object that requests the creation of a socket device to communicate with the guest system.

```
class VZVirtioSocketDeviceConfiguration
```

## Overview

Use a [`VZVirtioSocketDeviceConfiguration`](/documentation/Virtualization/VZVirtioSocketDeviceConfiguration) object to implement port-based communication between the guest operating system and the host computer. When you add this object to the [`socketDevices`](/documentation/Virtualization/VZVirtualMachineConfiguration/socketDevices) property of your [`VZVirtualMachineConfiguration`](/documentation/Virtualization/VZVirtualMachineConfiguration), the virtual machine provides a corresponding [`VZVirtioSocketDevice`](/documentation/Virtualization/VZVirtioSocketDevice) object to use to configure the ports. Add only one [`VZVirtioSocketDeviceConfiguration`](/documentation/Virtualization/VZVirtioSocketDeviceConfiguration) to your virtual machine’s configuration.

## Topics

### Creating the Configuration Object

[`init()`](/documentation/Virtualization/VZVirtioSocketDeviceConfiguration/init())

Creates a socket device configuration object.
