# VZNetworkDeviceAttachment

The common behaviors for the network attachment points of your virtual machine.

## Declaration

```swift
class VZNetworkDeviceAttachment
```

## Overview

Overview Don’t create a VZNetworkDeviceAttachment object directly. Instead, instantiate one of its concrete subclasses and use that object to configure your network devices. Each concrete subclass represents a specific type of network interface on the host computer.
