VirtualBox 3.1.4 Beta1

VirtualBox is an x86 virtualization software package, originally created by German software company Innotek, now developed by Sun Microsystems as part of its Sun xVM virtualization platform. VirtualBox is installed on an existing host operating system; within this application, additional operating systems, each known as a Guest OS, can be loaded and run, each with its own virtual environment. VirtualBox supported host operating systems include Linux, Mac OS X, OS/2 Warp, Windows XP, Windows Vista, Windows 7 and Solaris; there is also an experimental port to FreeBSD. VirtualBox supported guest operating systems include a small number of versions of NetBSD and various versions of DragonFlyBSD, FreeBSD, Linux, OpenBSD, OS/2 Warp, Windows, Solaris, Haiku, Syllable, ReactOS and SkyOS. VirtualBox latest version also supports Windows 7.

VirtualBox Features:

•  64-bit guests (64-bit hosts with CPU virtualization extensions or experimentally on 64-bit capable 32-bit host operating systems)
•  NCQ support for SATA raw disks and partitions
•  Snapshots
•  Seamless mode
•  Clipboard
•  Shared folders
•  Special drivers and utilities to facilitate switching between systems
•  Experimental OpenGL drivers for win32 and Linux to render on Host hardware
•  Command line interaction (in addition to the GUI)
•  Public API (Java, Python, SOAP, XPCOM) to control VM configuration and execution [17]
•  Remote display (useful for headless host machines)
•  Nested paging for AMD-V and Intel Core i7
•  Raw hard disk access - allows physical hard disk partitions on the host system to appear in the guest system
•  VMware Virtual Machine Disk Format (VMDK) support - allows VirtualBox to exchange disk images with VMware
•  Microsoft VHD support
•  3D virtualization (Limited support for OpenGL was added to v2.1, more support was added to v2.2, penGL  2.0 and Direct3D support was added in VirtualBox 3.0)
