# entropyDevices

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

## Declaration

```swift
var entropyDevices: [VZEntropyDeviceConfiguration] { get set }
```

## Discussion

Discussion The default value of this property is an empty array. Add one or more entropy configuration objects if you want to provide the guest operating system with a source of entropy for its random number generator.
