Best Virtualization Software of 2026

With a number of employees using personal networks (and devices) for remote work, IT managers are tasked with the challenges of handling multiple mobile devices spread across the globe while protecting sensitive business data.

One way IT managers can resolve this issue is by making the infrastructure of technology more efficient with virtualization. Virtualization tools can help you extend the capabilities of your existing hardware and software without commanding huge investments in physical servers. It can connect your remote desktops to virtual servers created with minimal hardware support, and lets you monitor and upgrade them from anywhere with just a click.

With several virtualization systems available in the market, selecting the right one can be confusing and time consuming. This buyers guide has all the information you’ll need to make a software choice that works for your business.

Here's what we'll cover:

• What is virtualization software?

• Common features of virtualization software

• What type of buyer are you?

• Benefits of virtualization software

• Key considerations

What is virtualization software?

Virtualization software is a solution that allows users to run multiple operating systems virtually on single computer hardware. It splits the central processing unit (CPU), server, storage, and memory into several virtual machines (VMs)–a piece of software that pretends to be a computer–each with its own operating system and applications. For example, you can operate a Linux virtual machine on Windows hardware.

The software enables companies to consolidate their IT resources on fewer physical machines which helps them improve overall IT turnaround in less space, power, and administrative overheads. Desktop virtualization tools are also used by developers and testers to test applications in multiple environments, say Windows and Mac, on one piece of hardware.

Common features of virtualization software

These are the common features most buyers seek when purchasing virtualization software:

What type of buyer are you?

Before you start evaluating software options, you'll want to know which buyer category you belong to. Most buyers of virtualization software fall into one of these categories:

• Small businesses (less than 100 employees): These are startups and small organizations that work with a small group of IT developers, freelancers, testers, and programmers to build a technological product. Software tools providing virtualization on desktops with multiple OS support and group sharing features are ideal for them. These software solutions are cheaper than business-grade versions and provide easy-to-setup virtual machines with minuscule downtime.

• Midsize businesses (from 100 to 500 employees): These buyers have a small employee base with growing IT requirements. But they expect to host fewer virtual machines compared with large businesses. They opt for virtualization software with desktop as well as server virtualization options to be able to control the workload centrally as their teams work remotely. They look for slightly more advanced features than small businesses, such as virtual desktop infrastructure (VDI), multi-factor authentication, and easy data migration. Another aspect of determining a good fit for software for these buyers is to assess the compatibility of existing hardware, including CPU, RAM, and hard drive storage, with the workload they plan to manage on the virtual systems.

• Large businesses (over 500 employees): These buyers are large IT organizations comprising different teams and departments with varying business needs. They have deeper customization and integration requirements than SMBs. As such, they will need a solution with server virtualization that can allow for scalability of virtual machines, and storage virtualization to have more control of their data and information. These buyers should opt for a full-featured solution that offers advanced virtual machine monitoring or Type 1 hypervisor support, easy integration and deployment, configuration management, storage virtualization, disaster recovery, and responsive customer support. They should also look at the compatibility of old applications with hardware virtualization so that the data can be easily shared with the virtual machines.

Benefits of virtualization software

Let’s go through some of the key benefits of using a virtualization software solution in your business:

• Reduced costs with hardware virtualization: Virtualization tools allow many operating systems and applications to run on fewer servers. This dramatically reduces the costs of acquiring the physical servers and the prices associated with storing and cooling them. Beyond savings on physical servers, virtual desktops save companies in software licensing costs by distributing computing power between users.

• Improved business resilience: Virtualization technology makes a return to normalcy faster after a disaster. It allows businesses to back up mission-critical applications on a few servers stored at an alternate location, and live migration enables businesses to resume productivity with minimum to no interruption.

• Efficient IT asset management: Software virtualization reduces software deployment time and administration efforts with one-click control and provides IT departments the flexibility to redistribute virtual hardware as per every user’s requirements. This enables IT teams to become much more adaptable and responsive to business needs.

Key Considerations

Listed below are some key considerations to keep in mind when purchasing a virtualization tool.

• Hardware: Even though virtualization enables software resources to better utilize the underlying hardware, it doesn’t mean that the hardware itself has no bearing on the success of virtualization. Check for the type and ability of your hardware, whether it’s a workstation or a physical server, to host your virtualization solution.

• System compatibility: Check if the virtualization tool you’re planning to buy supports the different types and versions of the operating system you intend to use. If you are purchasing virtualization tools for your software and IT development teams, ensure the solution you’re selecting supports the platforms on which they want to test their applications.

• Budget: Investing in software features that your IT teams don’t need will not benefit your business. Discuss your needs with team members first. Understand your workload requirements and jot down a list of must-haves versus good-to-have virtualization features. Also, take a look at the licensing costs versus the total cost of ownership. After that, select a tool that best offers what you need without stressing your budget.
