11 Best Free Virtual Machine Software in 2024

In the ever-evolving computing landscape, virtualization is the technology that transforms hardware resource utilization. 

At the heart of this groundbreaking technology lies virtual machines (VM) tools meant to create and manage multiple isolated computing environments within a single physical host.

Virtual machines come in all shapes and sizes. A VM could be a virtual desktop infrastructure or a fully functional server. Virtualized applications, servers, and other machines provide scalable, versatile functionality for users. 

You can experiment with virtual machines to try out a new operating system, make a virtual disk image of your hard drive, or go even further to construct an entire database server in the cloud.

Luckily, many server virtualization tools are free or open source, so you save money when you’re building a computer for your computer.

“The platform is straightforward to set up and deploy. Once it’s up and running, spinning up new VMs and setting up backup scheduling is a breeze. I appreciate that you can purchase a cost-effective and comprehensive snapshot system while keeping your other systems dedicated to VMs. In the six years of utilizing Scale, I’ve only needed to contact support four times. Each interaction has been both friendly and professional, which is one of the main advantages of using the Scale system.”

Scale Computing Platform Review, Cliff W.

What users dislike:

“I would appreciate having the option to continue receiving software support for “outdated” or end-of-life products. I can source replacement hard drives in case of failure, so having an extended software support option would be beneficial. This would allow me to extend the life of products for use as disaster recovery failover or archive servers.”

The fact that VMware allows one to install multiple operating systems makes it a worthwhile application. To top it off, it is a cross-platform application. I can use it on MAC, Windows, and even Linux.”

VMware Fusion Review, Christian I.

What users dislike:

The only thing I found to be a bit trickier to set up in VMware Fusion is the CPU/RAM/solid state drive (SSD) settings. Parallels had some handy templates when setting up a VM for the first time. VMware was missing that, which wasn’t ideal, but I could still do it (just a learning curve, and they may have fixed this by now).”

VMware Fusion Review, Adam M.

11.  VMware vSphere

Category: Server Virtualization Software

VMware vSphere is a bare-metal hypervisor used for server virtualization. It comes with a built-in management tool, storage resource monitor, and hardened drivers for improved reliability. The hypervisor can support unlimited cores per CPU and unlimited CPUs per host. It can produce a maximum of eight virtual CPUs per virtual machine.

The hypervisor is available for free download.

What users like best:

The best thing that I like about the VMware vSphere hypervisor is its speed. We can deploy virtual servers/desktops in minutes, and thus we can use the CPU and memory of the server efficiently. It’s a type-1 hypervisor which virtualizes the servers into VMs. On top of the virtualized VMs, we can provision applications and desktops virtually.”

VMware vSphere Review, Charan N.

What users dislike:

“I do find that the learning curve is intense and that they could work on the knowledge base. You kind of have to be a specialist to manage this environment, which is less than ideal.”

VMware vSphere Review, Scott H.
