To successfully manage virtual machines (VMs), organizations have relied on virtualization technology, or hypervisors. Virtualization allows IT professionals to set up multiple virtual machines on the same hardware. These tools allow users to create self-contained virtual environments designed to mimic a discrete piece of hardware, often a server. By doing so, users can operate multiple VMs on a single server, which more efficiently distributes available compute resources across various applications and operating systems.
As with any digital task, the success of your virtualization efforts will hinge on the tools you use to support your VMs. From open-source tools to heavy-duty, enterprise-grade software, I’ll walk you through some of the best server virtualization software on the market. Additionally, I’ll discuss my preferred tool for managing these server virtualization software platforms—an essential consideration for businesses running dozens of virtual machines.

Benefits of Server Virtualization
Businesses thinking about setting up virtualized servers stand to benefit from these tools. In addition to better using server capacity, virtualization can make it easier to get new virtualized servers up and running compared to their physical counterparts. Rather than wasting time on purchase orders, installation, and setup, VMs make it possible to provision new servers in a matter of minutes. This means organizations can deploy server resources strategically and quickly meet their evolving needs without added hardware costs.
The best server virtualization can also significantly cut energy costs. Instead of operating multiple physical servers for a set number of tasks, VMs make it possible to consolidate organizational activities on fewer machines. Cutting down the amount of hardware, which consumes power, can keep energy bills down and help businesses meet sustainability goals.
How to Manage Server Virtualization
As organizations consider which platform best fits their server virtualization plan, their industry, and their budget, it’s important to think about how they’ll manage virtual servers after they’ve been created. Many hypervisors come with baseline tools to keep VMs running properly, but increasingly complex IT infrastructures with dozens or hundreds of virtualized assets call for independent management tools uniquely suited to these machines.
SolarWinds® Virtualization Manager (VMAN) can play a critical role in your virtualization operation by offering centralized oversight and control for servers and other VMs across on-premises, hybrid, and cloud environments.
