VirtualBox guest additions installs a video driver called vboxvideo. It allows for the machine to adjust its resolution to the dimensions of the application windows. It also allows for seamless mouse movement between the host machine and the virtual window. I manage a server that runs VirtualBox to host several machines. The host is located in an air conditioned server room separated from the main office by some distance. In the office I have a windows machine that typically boots to a Windows XP desktop. VirtualBox is installed with a guest configured to pxe boot from the server host.

I would like to boot an interface, using pxe, with guest additions functional. Apparently guest additions does not play nicely with the various VirtualBox kernel modules required for actual machines. I have enabled the vboxvideo module in lts.conf (/var/lib/tftpboot/ltsp/i386/lts.conf) and it does configure xorg.conf of the pxe client properly, but it does not seem to work. Maybe its because the host server uses the nvidia driver? The main /etc/X11/xorg.conf is configured with nvidia; I have tried it with vboxvideo, but that did not make sense to me so I quickly reverted the change.

How else would ltsp clients be configured; other than lts.conf?
