VirtualBox 4.0 released!
http://www.virtualbox.org/


Oracle today released VirtualBox 4.0, a new major release. It now has an open architecture using extension packs and the base package is under GPLv2


additions like the ability to re-size both VHD and VDI virtual hard disks, a smoother and more thorough VM deletion process, and support for more than 2GB of memory on 32-bit hosts. There's also an updated set of virtual hardware including the Intel ICH9 chipset and Intel HD audio, and the new scaled display mode makes VMs play nice with your physical displays regardless of their respective resolutions.

The new option to create .vbox shortcuts is a real convenience, as it allows you double-click (or single, depending on your preferences) launching of your favorite VMs. Windows, Linux, and Solaris guests can also now auto-mount shared folders, which makes it easier to access files on your host system.


Changelog for VirtualBox 4.0

This version is a major update. The following major new features were added:

* Reorganization of VirtualBox into a base package and Extension Packs; see chapter 1.5, Installing VirtualBox and extension packs, see the manual for more information
* New settings/disk file layout for VM portability; see chapter 10.1, Where VirtualBox stores its files, see the manual for more information
* Major rework of the GUI (now called “VirtualBox Manager”):
o Redesigned user interface with guest window preview (also for screenshots)
o New “scale” display mode with scaled guest display; see chapter 1.8.5, Resizing the machine’s window, see the manual for more information
o Support for creating and starting .vbox desktop shortcuts (bug #1889)
o The VM list is now sortable
o Machines can now be deleted easily without a trace including snapshots and saved states, and optionally including attached disk images (bug #5511; also, VBoxManage unregistervm --delete can do the same now)
o Built-in creation of desktop file shortcuts to start VMs on double click (bug #2322)
* VMM: support more than 1.5/2 GB guest RAM on 32-bit hosts
* New virtual hardware:
o Intel ICH9 chipset with three PCI buses, PCI Express and Message Signaled Interrupts (MSI); see chapter 3.4.1, “Motherboard” tab, see the manual for more information
o Intel HD Audio, for better support of modern guest operating systems (e.g. 64-bit Windows; bug #2785)
* Improvements to OVF support (see chapter 1.12, Importing and exporting virtual machines, see the manual for more information):
o Open Virtualization Format Archive (OVA) support
o Significant performance improvements during export and import
o Creation of the manifest file on export is optional now
o Imported disks can have formats other than VMDK
* Resource control: added support for limiting a VM’s CPU time and IO bandwidth; see chapter 5.8, Limiting bandwidth for disk images, see the manual for more information
* Storage: support asynchronous I/O for iSCSI, VMDK, VHD and Parallels images
* Storage: support for resizing VDI and VHD images; see chapter 8.21, VBoxManage modifyhd, see the manual for more information.
* Guest Additions: support for multiple virtual screens in Linux and Solaris guests using X.Org server 1.3 and later
* Language bindings: uniform Java bindings for both local (COM/XPCOM) and remote (SOAP) invocation APIs

In addition, the following items were fixed and/or added:

* VMM: Enable large page support by default on 64-bit hosts (applies to nested paging only)
* VMM: fixed guru meditation when running Minix (VT-x only; bug #6557)
* VMM: fixed crash under certain circumstances (Linux hosts only, non VT-x/AMD-V mode only; bugs #4529 and #7819)
* GUI: add configuration dialog for port forwarding in NAT mode (bug #1657)
* GUI: show the guest window content on save and restore
* GUI: certain GUI warnings don’t stop the VM output anymore
* GUI: fixed black fullscreen minitoolbar on KDE4 hosts (Linux hosts only; bug #5449)
* BIOS: implemented multi-sector reading to speed up booting of certain guests (e.g. Solaris)
* Bridged networking: improved throughput by filtering out outgoing packets intended for the host before they reach the physical network (Linux hosts only; bug #7792)
* 3D support: allow use of CR_SYSTEM_GL_PATH again (bug #6864)
* 3D support: fixed various clipping/visibility issues (bugs #5659, #5794, #5848, #6018, #6187, #6570)
* 3D support: guest application stack corruption when using glGetVertexAttrib[ifd]v (bug #7395)
* 3D support: fixed OpenGL support for libMesa 7.9
* 3D support: fixed Unity/Compiz crashes on natty
* 2D Video acceleration: multimonitor support
* VRDP: fixed rare crash in multimonitor configuration
* VRDP: support for upstream audio
* Display: fixed occasional guest resize crash
* NAT: port forwarding rules can be applied at runtime
* SATA: allow to attach CD/DVD-ROM drives including passthrough (bug #7058)
* Floppy: support readonly image files, taking this as the criteria for making the medium readonly (bug #5651)
* Audio: fixed memory corruption during playback under rare circumstances
* Audio: the DirectSound backend now allows VMs to be audible when another DirectSound application is active, including another VM (bug #5578)
* EFI: support for SATA disks and CDROMs

I kept my eye on beta :frusty: Every release increases size! (I've kept old build versions dating back when it was owned by innotek)
