By default /etc/X11/xorg.conf does not exist and is generated each time 
X starts (for most people this is the same as once per boot). You can 
have Xorg output its generated configuration in a new /etc/X11/xorg.conf 
file with the command "Xorg -configure" (you might need to get more 
specific and do "Xorg:[display number] -configure"). You can then edit 
this file and change the display resolution to whatever you need and it 
should be loaded every time X starts from then on.

But I might be completely misunderstanding where your problem lies and 
giving you wrong advice; I am not very familiar with virtual box. 
Anyway, its painless to try and see. If that doesn't work you might try 
editing/adding to the arguments in /boot/grub/grub.conf to pass explicit 
screen size info automatically there as well.
