How VirtualBox functions

You can run multiple OSs on top of VirtualBox, as guest OSs under one host operating system. Each guest OS can be independently started, stopped, and paused. You can configure each VM independently depending on its role or purpose. For example, you can have a VM running on Linux installed with an Oracle database that will play a role in the database server, whereas another VM can run on Windows hosting an Apache Tomcat installation and running as an application server. You can run the guest VM either on software or hardware assisted virtualization depending on the host hardware supportability. But virtualizing an OS on an x86 processor without any hardware virtualization support is a very tough and complicated task.
