VirtualBox

Oracle VM VirtualBox is a cross-platform virtualization application that installs on an existing computer or server based on Intel or AMD, whether they are running Windows, Mac OS X, Linux operating systems, or Oracle Solaris (OS). Oracle VM VirtualBox extends the capabilities of your current computer or server so that it can run multiple operating systems, within multiple virtual machines, at the same time. Like, for example, you can run Windows and Linux on your Mac, run Windows Server 2019 on your Linux server, run Linux on your Windows PC, etc., all together with your existing applications. You can install and run as many virtual machines as you want. The only practical limits are hard disk space and memory.

Oracle VM VirtualBox is deceptively simple but also very powerful. It can run anywhere from small embedded systems or desktop class machines to data center deployments and even in Cloud environments.
