There is an option
Device drivers
--> Virtualization drivers
--> Virtual Box Guest integration support
I've checked this to <M> and
Device Drivers
--> Graphics support
--> Direct Rendering Manager (XFree86...)
checked to <*>
In order to build the vboxvideo driver in kernel, you have to enable
Device drivers
--> Staging drivers
and then
Device drivers
--> Staging drivers
--> Virtual Box Graphics Card
Note that staging drivers are not yet finalized, they might work, but might NOT
work too!
Save way is to leave that staging stuff unchecked and install the VBox guest
additions
afterwards using stuff provided by Oracle at
https://download.virtualbox.org/virtualbox/5.2.16/VBoxGuestAdditions_5.2.16.iso.
