# VZVirtioDeviceSpecificConfiguration

The device-specific configuration for a Virtio device

```
class VZVirtioDeviceSpecificConfiguration
```

## Overview

This class represents a Virtio device’s device-specific configuration.

For more details about device-specific configuration for different Virtio devices, see the [Virtio specification](https://docs.oasis-open.org/virtio/virtio/v1.3/csd01/virtio-v1.3-csd01.html).

Serialize any device-specific configuration structure into an
<doc://com.apple.documentation/documentation/Foundation/NSData> object, and instantiate a
[`VZVirtioDeviceSpecificConfiguration`](/documentation/Virtualization/VZVirtioDeviceSpecificConfiguration) object with it, and set this object on the
[`deviceSpecificConfiguration`](/documentation/Virtualization/VZCustomVirtioDeviceConfiguration/deviceSpecificConfiguration) property.

## Topics

### Initializers

[`init(configurationData: Data)`](/documentation/Virtualization/VZVirtioDeviceSpecificConfiguration/init(configurationData:))

Initializes a Virtio device specific configuration object with the configuration data you provide

### Instance Properties

[`var configurationData: Data`](/documentation/Virtualization/VZVirtioDeviceSpecificConfiguration/configurationData)

The serialized device-specific configuration.
