# VZLinuxRosettaDirectoryShare

The Linux directory share for Rosetta.

## Declaration

```swift
class VZLinuxRosettaDirectoryShare
```

## Overview

Overview This directory share exposes the Rosetta directory from the host file system to the guest. The example below shows the process of creating a VZVirtualMachineConfiguration, and then associating the Rosetta directory share with the VM configuration. let tag = "EXAMPLE_TAG"   let configuration = VZVirtualMachineConfiguration() do {     try let validationError = VZVirtioFileSystemDeviceConfiguration.validateTag(tag)     let rosettaDirectoryShare = try VZLinuxRosettaDirectoryShare()     let fileSystemDevice = VZVirtioFileSystemDeviceConfiguration(tag: tag)     fileSystemDevice.share = rosettaDirectoryShare

configuration.directorySharingDevices = [ fileSystemDevice ] } catch VZError.invalidVirtualMachineConfiguration {     // Rosetta is unavailable. } For complete instructions on installing Rosetta see doc:running-intel-binaries-in-linux-vms-with-rosetta, which includes additional information about checking for Rosetta availability, mounting the directory share, and registering the Rosetta runtime binary to run Intel binaries in a guest VM. For information on using a custom kernel to enhance Rosetta performance, see Accelerating the performance of Rosetta.
