Instead of reinstalling applications on your physical system, you need Oracle VirtualBox. To test software that cannot be installed on your current operating system, you must install the operating system on a physical machine using a traditional method. At that point, system execution is suspended the user can resume using the system later. It is possible to “pause” a running virtual machine.


A virtual machine’s configuration options include how many CPU cores, RAM, and disk space to allocate to the VM. As a host operating system, VirtualBox supports Windows, Linux and macOS. The “guest” operating system refers to the operating system that is running inside the VM. The “host” operating system refers to the operating system on which VirtualBox is running.
