Support for various types of networking (NAT, Host Networking via Bridged, Internal).Support for audio virtualization (AC97, SoundBlaster 16).Experimental support for 3D hardware acceleration.Has a pronounced modular architecture with well-described components and provides user-friendly interfaces for access to virtual machines, which allow controlling of guest systems both through the GUI and through the command line and remotely. It is distinguished by high productivity and stability. Windows, GNU/Linux, BSD, Solaris, and other operating systems can be used as guest systems. Supports dynamic translation - most of the guest OS instructions are executed on real hardware. So, instead of running many such physical computers that are only partially used, one can pack many virtual machines onto a few powerful hosts and balance the loads between them.VirtualBox is a virtualization system designed to create a virtual machine with the hardware parameters of a real computer on which you can run any operating system. A lot of hardware resources as well as electricity is thereby wasted. Most of the time, computers today only use a fraction of their potential power and run with low average system loads. Virtualization can significantly reduce hardware and electricity costs. You can delete snapshots while a VM is running to reclaim disk space. Any number of snapshots can be created, allowing you to travel back and forward in virtual machine time. after installing misbehaving software or infecting the guest with a virus), one can easily switch back to a previous snapshot and avoid the need of frequent backups and restores. This way, one can freely experiment with a computing environment. On top of that, with the use of another VirtualBox feature called “snapshots”, one can save a particular state of a virtual machine and revert back to that state, if necessary. Once installed, a virtual machine and its virtual hard disks can be considered a “container” that can be arbitrarily frozen, woken up, copied, backed up, and transported between hosts. Installing and running a mail server becomes as easy as importing such an appliance into VirtualBox. With VirtualBox, such a complex setup (then often called an “appliance”) can be packed into a virtual machine. For example, installing a complete mail server solution on a real machine can be a tedious task. Software vendors can use virtual machines to ship entire software configurations.
