Download VirtualBox 4.3.10

Oracle has released version 4.3.10 of VirtualBox. VirtualBox can be used to install other operating systems in a virtual environment on a computer. In this way it is possible to use different operating systems on the same hardware side by side and at the same time. VirtualBox is available for Windows XP and above, OS X, Linux, and Solaris, and is capable of many guest operating systems to turn.

In version 4.3 of VirtualBox, among other things, the complete virtualization code has been rewritten, which has solved several problems and also shows several performance improvements. Furthermore, there is video capture and support for ipv6, several virtual machines running on the same computer can now communicate with each other via the internal network and there is support for multi-touch screens. This fifth update also includes the following improvements:

The following items were fixed and/or added:

• VMM: more work on improving the emulation of certain MSR registers on certain host CPUs (eg bugs #12734, #12736, #12744, #12748, #12686, #12770)
• VMM: fixed single-stepping for real-mode guests (VT-x without unrestricted guest execution) and some I/O instructions (bug #12636)
• VMM: fixed a potential problem with COW pages if nested paging is not available
• GUI: Mac OS X: experimental native full screen support for Mountain Lion and Mavericks (bug #12292)
• GUI: Mac OS X: removed the mini-toolbar minimize button which doesn’t work under Mac OS X full screen mode anyway

• GUI: fixed a potential crash when opening the preferences menu (bug #12862)
• OVF: fixed a crash of the VirtualBox Manager when re-starting guest export (bug #12586)
• 3D support: several fixes

• Storage: fixed a bug preventing to compact differential snapshots under certain conditions
• VBoxSVC: fixed a segmentation fault on Linux hosts if a very long path exists under /dev (bug #12760)
• API: fixed guest misbehavior under certain conditions if a storage medium was attached or removed at VM runtime
• Windows installer: make the –silent parameter work again (bug #12764)
• Mac OS X Networking: prevent local traffic (VM-to/from-host) from leaking to wire (bug #12750)
• Windows Additions: fixed the environment for guest processes (4.3.8 regression; bug #12782)
• Windows Additions/WDDM: fixed divide by zero exception with multiple guest screens under certain conditions
• Linux Additions: install correctly on Ubuntu guest systems with a /usr/lib64 directory (bug #12513)
• X11 Additions: fix for the VBoxClient process not exiting correctly (bug #12348) and consuming too much processor time
