# customVirtioDevices

The array of custom virtio devices that you expose to the guest operating system.

```
var customVirtioDevices: [VZCustomVirtioDeviceConfiguration] { get set }
```

## Discussion

The default value of this property is an empty array. If your VM exposes one or more virtio  devices, assign an array of [`VZCustomVirtioDeviceConfiguration`](/documentation/Virtualization/VZCustomVirtioDeviceConfiguration) objects to this property.

## See Also

[`class VZCustomVirtioDeviceConfiguration`](/documentation/Virtualization/VZCustomVirtioDeviceConfiguration)
