Oracle VM VirtualBox is a virtualization software package originally developed by Inntek and is now being released by Oracle Corporation. Initially released in 2007, Oracle VM Virtual Box installs on your current AMD- or Intel-based computers whatever operating system you may have. It also extends your computer’s capabilities by allowing it to run several operating systems simultaneously on a single host operating system (OS).
Each guest operating system can be paused, started, and stopped within its own virtual machine independently. Users may also choose to configure the loaded VMs under either hardware-assisted virtualization or software-based virtualization. Communication between the guest OS and host OS is possible through different mechanisms such as virtualized network facility and a common clipboard. VirtualBox also features device virtualization allowing the computer to emulate hard disk in three disk image formats (VMware Virtual Machine Disk format, Virtual Disk Image format and Microsoft Virtual PC VHD format). This allows users to utilize disk originally created in Microsoft Virtual PC or VMware.
VirtualBox runs on both 64-bit and 32-bit operating systems. The program features Guest Additions, which are software packages that can be installed inside the guest VMs. Once this feature is installed, the VM can support seamless windows, automatic adjustment resolutions of videos, accelerated 3D graphics and more. The program also supports different hardware including USB Device, Guest Multiprocessing (SMP), Hardware Compatibility, Multi-Screen Resolution and more.
