VirtualBox is a virtualization tool for both enterprise and home use, that allows you to create virtual machines. This Open Source application is feature rich and boasts high performance, enabling you to run multiple guest operating systems that include Windows (NT 4.0, 2000, XP, Server 2003, Vista), DOS/Windows 3.x, Linux (2.4 and 2.6), and OpenBSD.
Everyone is encouraged to contribute to VirtualBox and that will lead to more features, an increase in supported guest operating systems and platforms.
The following items were fixed and/or added:
User interface: fixed a segmentation fault when accessing the interface through VNC.
User interface: X11: handle repeating keys on the host system correctly.
VMM: Fixed emulation of the undocumented SALC instruction
VMM: Fixed emulation of so-called "huge unreal mode" ; this in practice only affected Intel CPUs with VT-x without unrestricted execution.
Keyboard: The PS/2 keyboard emulation has been corrected to not queue partial scan code sequences ; this problem was likely only visible on Linux hosts due to losing the fix.
Storage: Fixed CUE file support to correct REM keyword parsing.
USB: Fixed a problem where the emulated xHCI device under very rare circumstances failed to report an empty isochronous transfer ring error, causing the transfers on the corresponding endpoint to stop.
Audio: fixed Linux kernel log flooding.
Apple hosts: make kernel driver load with Mac OS Mojave pre-release.
Linux guests: made vboxvideo driver build with kernel 4.17 and with pre-3.14 and EL 7.1 kernels.
