Overview
VirtualBox or Oracle VM VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL).
As of version 4.0, VirtualBox introduces the Extension Pack mechanism which allows Oracle and 3rd parties to deliver additional functionality on top of the standard Open Source product.
Presently, VirtualBox runs on Windows, Linux, Macintosh and OpenSolaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7), DOS/Windows 3.x, Linux (2.4 and 2.6), Solaris and OpenSolaris, and OpenBSD.

This build includes the following updates:
- VMM: another TLB invalidation fix for non-present pages.

- USB: properly handle orphaned URBs (bug #11207).
- BIOS: fixed function for returning the PCI interrupt routing table (fixes NetWare 6.x guests).
- BIOS: don't use the ENTER / LEAVE instructions in the BIOS as these don't work in the real mode as set up by certain guests (e.g. Plan 9 and QNX 4).
- DMI: allow to configure DmiChassisType (bug #11832).
- Storage: fixed lost writes if iSCSI is used with snapshots and asynchronous I/O (bug #11479).

- Storage: fixed hang when creating a snapshot using Parallels disk images (bug #9617).
- 3D: seamless + 3D fixes (bug #11723).
- 3D: version 4.2.12 was not able to read saved states of older versions under certain conditions (bug #11718).
- Main/Properties: don't create a guest property for non-running VMs if the property does not exist and is about to be removed (bug #11765).
- Main/Properties: don't forget to make new guest properties persistent after the VM was terminated (bug #11719).
- Main/Display: don't lose seamless regions during screen resize.
- Main/OVF: don't crash during import if the client forgot to call Appliance::interpret() (bug #10845).
- Main/OVF: don't create invalid appliances by stripping the file name if the VM name is very long (bug #11814).
- Main/OVF: don't fail if the appliance contains multiple file references (bug #10689).
- Main/Metrics: fixed Solaris file descriptor leak.
- Settings: limit depth of snapshot tree to 250 levels, as more will lead to decreased performance and may trigger crashes.
- VBoxManage: fixed setting the parent UUID on diff images using sethdparentuuid.
- Linux hosts: work around for not crashing as a result of automatic NUMA balancing which was introduced in Linux 3.8 (bug #11610).
- Windows installer: force the installation of the public certificate in background (i.e. completely prevent user interaction) if the --silent command line option is specified.
- Windows Additions: fixed problems with partial install in the unattended case.
