VirtualBox is an application for creating virtual machines. A virtual machine is a software based computer, running inside your own. They have various uses, but one is to have an isolated environment in which to test software. The graphical user interface of VirtualBox has long been inaccessible to the blind—leaving the command line as the only option. Having said that, this guide may also be of interest to others. If you are a system administrator, for example, you might use the information here to automate the task of maintaining the virtual machines your company uses. Technical manuals, such as the one for VBoxManage—the command line interface to VirtualBox—do not exactly make for scintillating reading, thus, this guide.
