Compare the Top Free Virtual Machine Software as of December 2025

What is Free Virtual Machine Software?

Virtual machine software allows users to run multiple operating systems on a single physical computer by creating isolated, virtualized environments. Each virtual machine (VM) operates as a fully functional computer with its own CPU, memory, storage, and network resources, independent of the host system. This technology is widely used for software testing, development, running legacy applications, and server consolidation. Many VM solutions support snapshots, cloning, and resource management to optimize performance and recovery. By enabling flexibility, scalability, and cost savings, virtual machine software is a cornerstone of modern IT infrastructure and cloud computing. Compare and read user reviews of the best Free Virtual Machine software currently available using the table below. This list is updated regularly.
