Windows Server Automation with PowerShell Cookbook - Fourth Edition

By: Thomas Lee

Overview of this book

With a foreword from PowerShell creator Jeffrey Snover, this heavily updated edition is designed to help you learn how to use PowerShell 7.1 effectively and manage the core roles, features, and services of Windows Server in an enterprise setting. All scripts are compatible with both Window Server 2022 and 2019. This latest edition equips you with over 100 recipes you'll need in day-to-day work, covering a wide range of fundamental and more advanced use cases. We look at how to install and configure PowerShell 7.1, along with useful new features and optimizations, and how the PowerShell compatibility solution bridges the gap to older versions of PowerShell. Topics include using PowerShell to manage networking and DHCP in Windows Server, objects in Active Directory, Hyper-V, and Azure. Debugging is crucial, so the book shows you how to use some powerful tools to diagnose and resolve issues with Windows Server.

Implementing nested virtualization

Nested virtualization is a feature that enables a Hyper-V VM to host VMs that also have virtualization enabled. You could, for example, take a Hyper-V host (say, HV1) and on that host run a VM (say, PSDirect). With nested virtualization, you could enable your PSDirect VM to host VMs. You could then create a nested VM inside the PSDirect VM called NestedVM.

Nested VMs have many uses. First, nested VMs hosted in one VM are provided with hardware isolation from nested VMs run in other VMs. In this case, nested virtualization provides a further level of security for VMs.

Nested virtualization is also helpful for testing and education/training. You could give students a single VM (on a large blade server, for example). Nested virtualization enables them to create additional VMs as part of the course lab work. And most IT pros just find it cool! You can, for example, run all the recipes in this chapter using nested virtualization.
