BLFS Xorg: Fatal server error no screens found

I'm trying to build the Xorg X Window System Environment as outlined in Beyond Linux From Scratch Version 8.0. My BLFS system resides in a Virtual Machine using VirtualBox Version 5.0.10 r104061. I followed the steps as outlined in Chapter 24. X Window System Environment. However, when I finished my installation and tried startx, I got the output below:- Release Date: 2017-01-11 X Protocol Version 11, Revision 0 Build Operating System: Linux 4.9.5 x86_64 Current Operating System: Linux LFS 4.9.5 #1 SMP Thu Feb 23 22:59:41 GMT 2017 x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.9.5-lfs-SVN-20170122 root=/dev/sda1 ro Build Date: 01 March 2017 10:04:52PM Current version of pixman: 0.34.0 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

I've tried rebuilding the kernel with Device Drivers ---> Graphics support ---> Direct Rendering Manager (XFree86 ... support) ---> [CONFIG_DRM] DRM driver for VMware Virtual GPU [CONFIG_DRM_VMWGFX] [*] Enable framebuffer console under vmwgfx by default [CONFIG_DRM_VMWGFX_FBCON] and Device Drivers ---> Graphics support ---> Direct Rendering Manager (XFree86 ... support) ---> [CONFIG_DRM] and in both cases got the same error message. This is the output of lspci for the graphics adapter 00:02.0 VGA compatible controller: InnoTek Systemberatung GmbH VirtualBox Graphics Adapter Any idea why the screens are failing to load?
