# VZVirtioNetworkDeviceConfiguration

A configuration object that requests the creation of a network device for the guest system.

```
class VZVirtioNetworkDeviceConfiguration
```

## Overview

Use a [`VZVirtioNetworkDeviceConfiguration`](/documentation/Virtualization/VZVirtioNetworkDeviceConfiguration) object to configure one network interface of your virtual machine. After creating this object, assign an appropriate value to its inherited [`attachment`](/documentation/Virtualization/VZNetworkDeviceConfiguration/attachment) property to define the type of network interface you want. You can also assign a specific MAC address, or let the system generate a random address for you.

After creating and configuring a [`VZVirtioNetworkDeviceConfiguration`](/documentation/Virtualization/VZVirtioNetworkDeviceConfiguration) object, assign it to the [`networkDevices`](/documentation/Virtualization/VZVirtualMachineConfiguration/networkDevices) property of your virtual machine’s configuration.

## Topics

### Creating the configuration object

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