Not sure I'm following you here.  THe guest addtions come with the
Vbox and I've already installed them.

This is a windows 10 host and the vbox is the one installable on
windows. This is version 5.1.14

Guest additinos have nothing to do with gentoo kernel config.

What I'm asking about it setting up a kernel for gentoo os preparatory
to installing X.  As described in the Xorg gentoo wiki. Vbox vm's need
drivers like any other os.

I'm asking which driver works with the vbox graphics adapter.
And how to get a hi-res frame buffer using kernel KMS.


I've never done that (building kernel for a VM) so can't offer a solution but in my Lubuntu VM the list of modules does not seem to include a specific driver for the Windows Host graphic card (NVidia NVS3100); there is instead a vboxvideo module and a generic drm_kms_helper.
