Software Update: VirtualBox 5.1.2

The first update for VirtualBox version 5.1 has been released. 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, MacOS, Linux and Solaris, and is able to guest operating systems to turn.

In version 5.1 of VirtualBox we find, among other things, new apic implementations that provide various performance improvements, there is improved support for Python 3 and the interface has been switched to Qt5. The following improvements have also been made in this update:
