Install 3D HW Acell on Windows XP Vitrualbox:
==============================================
As of Virtualbox 6.0 & newer, the VBoxVGA adapter used in OS's before Windows 7 is no longer supported,
Therefore You cant install 3D graphics on Windows XP.
You can the VirtualBox 5.2 guest edition iso, and install it and safe mode in xp and it will give you the option to install it, and works partly under backwards capability (manly only openGL 1.1, no Direct X for example).


You will also need to edit the vbox file of the vm to add 256MB of video memory that was not available previously.
