VirtualBox fixes startup problems with Windows hosts, squashes more bugs
Oracle has released VirtualBox 4.3.16, the latest in a series of maintenance fixes for its cross-platform, part-open-source virtualization program.
The most notable fix in the new build affected a number of Windows hosts, which found themselves unable to open VMs. The only workaround had been to revert to the previous build (4.3.12).
A number of graphic user interface bugs have also been resolved with the new release: the mini toolbar should now produce less artifacts when used with 3D guest rendering, while Mac users should find the native full-screen to multi-screen transition no longer blacks out host screens for up to a minute.
One additional feature has been added allowing users to disable mouse capture for selected VMs -- typically headless machines or those using command-line interfaces where the mouse isn’t required. Sadly, this hasn’t made it into the graphical user interface; instead users should read section 9.19.10 of the manual for details of setting it using the command-line VBoxManage interface.
3D support has been improved for OS X hosts via the implementation of experimental support for rendering on offline GPUs in version 4.3.16. Other 3D fixes include one for MS Office 2013 support as well fixing an issue with video recording.
Bridged Networking has been tweaked to better support IPv6 when bridging to a wireless interface, while a number of USB regressions from version 4.3.14 have also been fixed. For a complete list of fixes and changes, check out the changelog.
