VirtualBox 4.0.12.72916

VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.

Some of the features of VirtualBox are:

  • Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox.
  • Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.

Changelog:

* Mac OS X hosts: Lion fixes
* Solaris hosts: fixed preemption issue with Solaris 11 hosts (builds 166 and above)
* VBoxManage: more convenient configuration of storage controller attachments by automatically determining the port or device parameter when a storage controller has only one port or device per port
* Storage: fixed possible data corruption under certain circumstances whith VHD and Parallels images
* Storage: fixed access to CD/DVD images beyond 4GB when using the SATA controller
* Floppy: make it possible to unmount a host floppy disk
* Networking: fixed the problem with segmentation offloading when several VMs were transmitting at once
* 3D support: fixed GL_VERSION string for different locales
* Sources: fixed USB 2.0 support using extension packs for non-official builds
* Solaris Additions: fixed automounting of shared folders
