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.
