The beginner's guide to Hyper-V

Last updated:August 2019

Editor's note

Microsoft Hyper-V provides several features and services that help IT administrators manage virtual resources, such as high availability and shielded VMs. It enables admins to run many VMs at one time, and live migrations are generally a simple task.

Though the advantages of Hyper-V are numerous, there are some disadvantages that can cause problems, especially for those who might not be as familiar with the technology. For example, if an admin needs to execute a security update reboot while using Hyper-V, every single VM must be offline before updating; missing this step can cause issues. Before using Hyper-V, learn the ins and outs of the technology to simplify both use and management.

1Get to know Hyper-V features

Hyper-V provides admins with several features to help simplify virtualization operations and tasks. For example, Hyper-V shielded VMs enable admins to strengthen security in their environments. Nested virtualization enables admins to run a hypervisor -- or a container -- within a VM. All of these features are vital to Hyper-V operations, and admins should familiarize themselves with them.

2Improve and maintain Hyper-V security

Security is an essential component to any virtual environment. Without it, admins risk exposing their environments to malicious attacks, such as Meltdown and Spectre. By bolstering Hyper-V security and enabling different features, such as Host Guardian Service, admins can properly protect their environments from weaknesses in their defenses.

3Understand Hyper-V containers

Although container technology is fairly new, adoption numbers are increasing. Because of this, those new to Hyper-V should familiarize themselves with Hyper-V containers. Container technology provides more flexibility and portability than VMs, but Hyper-V containers also operate much differently than Hyper-V VMs.

4Manage Hyper-V using PowerShell

PowerShell helps automate several Hyper-V tasks, such as the creation and management of VMs, but there are other ways that PowerShell assists admins with Hyper-V. PowerShell enables admins to better manage and track Hyper-V clusters, simplifying the vast amounts of information related to clusters, and manage the secure boot feature in Hyper-V.
