Новая версия виртуальной машины от Oracle. Из основных нововведений, отмечается поддержка изменения сетевых параметров налету, возможность определения значения счетчика портов для SATA-контроллеров, поддержка режима связанного клонирования, возможность переименования дисков в клоне, экспериментальная поддержка проброса PCI-устройств в реализации хост-систем, работающих под управлением Linux и незначительная переработка некоторых диалогов в пользовательском интерфейсе.

Ключевые улучшения:

• Support for cloning of VMs (bug #5853, see the manual for more information): full clones can be created through the GUI and VBoxManage, linked clones only through VBoxManage
• GUI: enhanced wizard for creating new virtual disks
• GUI: new wizard for copying virtual disks
• GUI: keep the aspect ratio in scale mode (Windows and OSX hosts only; bug #7822)
• VMM: raised the memory limit for 64-bit hosts to 1TB
• Experimental support for PCI passthrough for Linux hosts, see the manual for more information
• Windows guests: Experimental WDDM graphics driver, supporting Windows Aero (bug #4607) and providing Direct3D support using a cleaner approach (no need to install the guest drivers in Safe Mode anymore)
• Guest Additions: status of modules and features can now be queried separately by the frontends
• Networking: new network attachment mode "Generic Driver", which offers an open plugin architecture for arbitrary and separately distributable virtual network implementations
• Host-only Networking: fixed host crash in kernels prior to 2.6.29
• New Networking Mode UDP Tunnel: allows to interconnect VMs running on different hosts easily and transparently, see the manual for more information
• Experimental support for SATA hard disk hotplugging available with VBoxManage
• Solaris hosts: New Crossbow based bridged networking driver for Solaris 11 build 159 and above
