VirtualBox v4.1.16 is released. VirtualBox is a general-purpose full virtualizer for x86/x64 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.

VirtualBox v4.1.16 Changelog:
This is a maintenance release. The following items were fixed and/or added since VirtualBox 4.1.14:
- VMM: fixed a Guru Meditation VERR_ACCESS_DENIED with certain guests (bugs #7589, #8247)
- VMM: fixed a Guru Meditation VERR_PAGE_TABLE_NOT_PRESENT with Ubuntu 32-bit guests with nested paging enabled on AMD CPUs (bug #10183)
- VMM: preserve segment limits and attributes when switching to unreal mode required for some legacy guests to work properly (VT-x without unrestricted guest execution only; bug #9941)
- VMM: fixed a VM hang after a resume from pause / savestate with SMP guests in rare cases
- 3D Support: several fixes for the Windows WDDM video driver crash
- NAT: fixed a crash on attempt to process ICMP datagram under some circumstances (bug #10527)
- Host-only Networking: lifted the maximal number of interfaces to 128 on Linux and Mac OS X hosts (there is no such limitation for Solaris and Windows hosts)
- EFI: fixed wrong SEC/PEI Core entry point calculation (bug #10531)
- VRDP: fixed a display update problem (bug #10503)
- Main: set the proper VM state if savestate failed for some reason (bug #6189)
- Main: more useful error message if a medium is inaccessible
- VBoxManage: fixed controlvm savestate if the VM is already paused
- Mac OS X hosts: addressed issues running on Mountain Lion Preview 3 (bug #10267)
- Linux hosts: Linux 3.4 compile fixes
- Linux hosts: fixed wrong help path in some rpm-based packages (bug #10418)
- Guest Additions: fixed handling of custom environment variables during VBoxManage guestcontrol execute (bug #10581)
- Windows Additions: fixed guest driver crash of VBoxSF in certain cases (4.1.10 regression, bug #10408)
- Windows Additions: don't load the WDDM driver if 3D support is not available for Windows 8 guests to keep the guest maintainable in that case (still better to miss some features than providing a blank screen)
- Solaris Additions: added support for X.org Server 1.11 and 1.12
