This practical book unveils the robust capabilities and easy-to-use graphical interface of VirtualBox to help you to effectively administer and use virtual machines in a home/office environment. You begin by creating your first virtual machine on a Windows/Linux guest operating system and installing guest additions. The book then goes on to discuss the various formats that VirtualBox supports and how it interacts with other formats. The comprehensive instructions will help you to work with all the networking modes offered by VirtualBox. Virtual appliances will be explained in detail–how they help to reduce installation time for virtual machines and run them from VirtualBox. By the end of this book you will be able to run your own headless VirtualBox server, to create, manage, and run virtual machines in that server from a remote PC.
