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.

QEMU

QEMU

QEMU is a generic and open-source machine emulator and virtualizer. Run operating systems for any machine, on any supported architecture. Run programs for another Linux/BSD target, on any supported architecture. Run KVM and Xen virtual machines with near-native performance. Guest memory dumps are now fully supported, along with pre-copy/post-copy migration and background guest snapshots. Support for nw DEVICE_UNPLUG_GUEST_ERROR to detect guest-reported hotplug failures. macOS hosts with Apple Silicon CPUs now support ‘hvf’ accelerator for AArch64 guests. M-profile MVE extension is now supported for Cortex-M55. AMD SEV guests now support measurement of kernel binary when doing direct kernel boot (not using a bootloader). Support for vhost-user and numa mem options across all boards.

KVM

Red Hat

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc. KVM is open source software. The kernel component of KVM is included in mainline Linux, as of 2.6.20. The userspace component of KVM is included in mainline QEMU, as of 1.3.
