Virtualization is a high-priced capability for IT professionals and programmers everywhere. The freedom to emulate more operating systems within their window from one computer is essential for resource administration and isolating critical processes from code testing or experimentation. Also known as hypervisors, the best free virtual machine software in 2019 can ease your work and increase platform compatibility.
What is a virtual machine?
A virtual machine (VM) is an operating system (OS) or an application that enables you to run multiple operating systems on the same physical hardware machine, and in a secure, isolated environment. For example, you can run and use a Windows 10 instance on a macOS Mojave machine or the other way around. Additionally, you can create several OS combinations that include Linux, Solaris, and Chrome OS.
The virtual machine that you install on your computer is known as the guest, while your physical hardware machine is referred to as the host. Some operating systems, like Windows, for example, will cost you the charge of a secondary license key. However, if you opt for Linux or any macOS released after 2009 (macOS 10.15 Catalina included) you will get them for free.
The versatility of virtual machines has made this type of software one of the most popular application among developers in recent years. While it might be difficult to pick out the absolute best virtual machine out there, we can still differentiate between buggy software and smooth-running programs to give you an idea about the VM that suits you best. Here are some of the most reliable virtual machine applications that also come for free:
Best Free Virtual Machine Software for Windows and Mac
1. Parallel’s Software (Mac)
If you are new to Virtual Machines, Parallels Desktop is probably the best choice for you. This is firstly because it helps you locate the ISO installer file and will help you in downloading this to your desktop. It can also help you find an Android, Ubuntu or Windows image depending on what software you want to run and finally it will help you create an install from the Recovery Disk on macOS.
This software as we have mentioned already helps you to run Windows, Android or Linux operating systems on your Mac without having to restart the machine. It also enables you to install a Virtual Machine to run Mac OS from disk recovery if you so desired.
However, like all of these solutions, each of them has advantages and disadvantages. They are as follows:
- It is effortless to use and perfect for newbie’s. It has a one-click install, and then you can connect to your Parallel’s Virtual Desktop over the internet. As we’ve mentioned as well, it helps you find and download the installer file. This means if you have very little knowledge about Virtual Machines you can still use it.
- Another useful feature is called ‘one-click tuning’ which allows you to cater your experience depending on productivity, games, design, software testing or even app development. The software itself will provide the performance depending on your intentions and purpose.
- The standard edition supports up to 8GB VRAM use and four vCPU’s. If you are an average user of Virtual Machines, this should be more than enough resources to run macOS.
- Coherence mode allows you to run Windows alongside Mac OS. You can also share files and folders using a simple drag and drop feature between both of these operating systems.
- The guest tool as we’ve mentioned allows 3D graphics in your Virtual Machine making the experience more optimal and seamless.
- Finally, it works with Boot Camp which will enable you to run macOS through.
- Removing a Virtual Machine through Parallel’s desktop is hard for newbie’s as there are plenty of edits and remove buttons, but many of these don’t actually close down and remove the Virtual machine.
- If you require more resources such as RAM and CPU, you will need to upgrade to the Pro Version to have these features.
2. VirtualBox (Mac & Windows)
If you are new to virtualization, then your best choice of using a virtual machine for the first time is definitely VirtualBox from Oracle. This hypervisor is open sourced and free, and you can use it at work just as easy as installing it on your home computer.
VirtualBox was released in 2007 and quickly gained popularity in the IT industry for its long list of supported operating systems. You can run any version of Windows from XP onwards on it, together OpenBSD, Solaris, and OpenSolaris. Additionally, you can easily install any release of Linux 2.4 and above.
This virtual machine is ideal for developers with hardcore Windows-nostalgia. VirtualBox lets you install the NT and Server 2003 versions as well as older releases like Windows 3.x or even IBM OS/2 on 2018 computers of the latest generation.
Apple users have the same delight in using VirtualBox on their machines, and the option to host a client Mac VM session is a plus for any developer out there. Since Apple only allows their systems to work on their trademark hardware, you will not be able to run macOS Mojave on a virtual machine using VirtualBox unless you have a Mac.
One of the best aspects of using VirtualBox is its portability that allows you to transfer a virtual machine from one host to another, regardless of the operating systems. Additionally, this hypervisor enables you to run several guest windows at the same time on the same machine.
Another great feature of VirtualBox is the seamless mode, which lets you run Windows applications and macOS side-by-side. The hypervisor optimizes system resources and hardware performance to reward you with the experience of running the guest seamlessly within the host. This process is available under the GPL 2 (If you're using VirtualBox OSE) and free of charge.
VirtualBox should be your go-to virtual machine if you are using older hardware. It provides you with a reliable resource of Guest Additions that are available for free and enables you to transfer files and data between the host and the guest regardless of the operating systems. More than that, this open source hypervisor supports USB devices, 3D virtualization, and video.
VirtualBox new users can find a great source of information and tutorials on the Oracle website, along with a long string of pre-built virtual machines. Tutorials and how-to guides are also available if you get stuck at any point during the installation process.
So far, VirtualBox has garnered over 100,000 registered users that form a busy and enthusiastic community that you can also join to gain access to the latest software releases. Here are the main features of VirtualBox in a nutshell:
3. VMware Workstation Player (Windows, Linux)
VMware is one of the markets leading developers of virtual machines. Their trademark hypervisors include VMware Fusion (macOS) and Vmware Workstation (PC). Both applications have the same features and ease of use, but each of their configurations is tailor-cut to the respective operating systems.
VMware Workstation Player for Windows or Linux is free of charge if you use it for personal purposes. However, if you want to upgrade to the Pro version you will have to pay for the license key, which may set your budget back with at least $100.
VMware Workstation has one of the largest databases of followers in the IT industry mainly due to the high standards of virtual machine software that the company has been upholding since its market launch over 20 years ago. Users are delighted at the possibility of running advanced 3D solutions on a hypervisor that supports both DirectX 10 and OpenGL 3.3 and maintaining video and photographic quality throughout the entire process.
An interesting feature of VMware Workstation Player is the snapshot system that allows you to create multiple instances of the virtual machine and set several rollback points during a testing process. This way, if anything goes wrong, you can return to a previous version or clone, also known as isolated duplicates to resume your progress.
If you choose the Workstation Player as your virtual machine, you will be able to host over 200 guests and share files and data between them and the host at a seamlessly high rate. Also, you will be able to connect to vSphere, which is VMware’s cloud storage system, and which can act as a remote data center for your hypervisor.
The Vmware Workstation Player is a reliable virtual machine, but it falls short when you compare it to its paid Pro version. Even if both can support 4K displays with ease, the free application runs slower with every host you add to the virtual machine, starting with the second one. Also, it makes cloning and the snapshot system almost impossible to use at a decent speed. If you are looking to use this software for enterprise purposes, your best choice would be to go for the Pro license.
