Using the software-accessibility keyboard in Windows I was able to
find out that the left Alt-key was always recognised as Alt+GR in
Windows. And yes, I checked the keyboard settings, multiple times. I
used Gnome-tinker-tool to set a few different Alt/Super-options on the
Linux side - nothing helped, Virtualbox would override it and always
send Alt+Gr...
In the end I used a program that remaps keys in the Windows Registry
