You don't *need* to run a thin client, you could run an ordinary distro with 
guest addons and xdm to your ltsp server.

I once tried Xnest from the Mac to achieve the same thing

Arch linux has a 'arch tools' not 'guest addons' guest addon suite. I'd look 
what and how they do. Alternatively install a system and list all files, then 
install guest addons diff to see what modules they add then put those in your 
chroot.

The answer from Christian does not work on VBox VMs (Christian the VBox screen 
size is set by the VM. You can't configure it until you install the 
guest-addons then you can drag the window size to what you like)
