VirtualBox is an easy and elegant solution for those who want to control a computer from another computer.
VirtualBox offers virtualize your operating system (OS) guests on a host machine. Called hypervisor, the application supports Windows OS X, Linux, Mac, Solaris, FreeBSD, etc.. as host, Mac OS X missing the call as a guest.
It also includes a remote access via HTTP protocol, convenient for demonstrations on a clean system. The ability to manage multiple states of the system is particularly interesting and its interface is very simple.
Virtualization solutions allow installing an operating system on a virtual machine using the resources of the host PC , thus enjoying very good performance. In the genre, several solutions are known for their ease of use, such as VMware Workstation , Parallels Desktop or Microsoft Virtual PC 2007 SP1.
A virtual machine is a useful way to use two operating systems simultaneously and harmless to the host computer. There is the possibility to install Linux on a virtual machine on Windows and vice versa .
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.
