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.

Change Log:

# This is a maintenance release. The following items were fixed and/or added:
* VMM: fixed guest crash with huge amount of guest RAM on VT-x hosts
* GUI: fixed a layout bug in the Mac OS X clone VM dialog
* GUI: not all the translation tags were taken into account during the language switch
* GUI: take guest screenshot dialog sometimes had no keyboard input available on Windows host
* Main/Machine: fix generation of spurious event for inaccessible VMs which triggered an endless event generation loop in cooperation with the GUI which became unresponsive (4.2.6 regression)
* Main/Display: fix for an access violation under certain conditions in multi-monitor configurations
* Main/Metrics: network metrics are now collected for active (up) interfaces only, the state of an interface being evaluated when the associated metric is enabled via setupMetrics
* Snapshots: reduce the time for merging snapshots under certain conditions
* Storage: fixed data corruption after resizing a VDI image under certain circumstances
* Storage: fixed non working online merging of snapshots (4.2.6 regression)
* Storage: fixed crash when connecting to certain QNAP iSCSI targets
* Storage: fixed incompatibility of VHD differencing images with Hyper-V
* Bridged Networking: fixed TCP pseudo header checksum computation for IPv6
* 3D support: fix Battlefield 1942 game crashes
* Settings: really sanitize the name of VM folders and settings file, the code was disabled before
* Settings: allow to change VRDE settings for saved VMs
* VBoxManage: don't crash during screenshotpng if there is no display
* Linux hosts: work around gcc bug 55940 which might lead to wrong kernel module code if gcc 4.7 is used to compile the 32-bit Linux host kernel
* Linux hosts: fixed inconsistent lock state and deadlock warnings on module load and VM startup when CONFIG_PROVE_LOCKING is enabled
* Linux hosts: made "]" key work again on Japanese keyboards
* Mac OS X hosts: don't crash the kernel during dtrace if the VBox kernel extensions are loaded (10.6 hosts only)
* Solaris / Mac OS X hosts: machine CPU load metrics now report 100% when all cores are fully utilized (used to be a single core)
* Solaris 11 host installer: wait for any services left over from a previous installation to be terminated to avoid confusing SMF.
* Guest Additions: don't block signals for processes executed via guest control
* Guest Additions: fixed a small memory leak in VBoxService
* Windows Additions: fixed shared folder issue with large reads/writes on 64 bit Windows guests
* Linux Additions: Linux 3.8 compile fixes
* X11 Additions: fixed blocked SIGALRM in 3D desktop sessions
* X11 Additions: fixed an unresolved reference in vboxvideo_drv for X.org 6.8 guests and before (e.g. RHEL4; 4.2.0 regression)
* X11 Additions: fixed screen automatic resizing for guests with X.org 1.3 or older (4.2.0 regression)
