Setting display size of linux guest on VirtualBox

Recently I have initiated a jeos image with VirtualBox , after booting I had a small sized shell window , which wasn’t really friendly to use .

Basic installation of jeos dosn’t have any X related stuff installed so I have found that there is an option to set vga mode ( resolution and color depth ) while setting vga=XXX on kernel setup of grub boot loader .

In /boot/grub/menu.lst line that begins with kernel and add vga=### to it . This value needs to be in decimal.

For example : 1024×768 16bit mode code is 0×317 which is 791 in decimal notation , so we should add vga=791 to kernel setup .

 Colours   640x400 640x480 800x600 1024x768 1152x864 1280x1024 1600x1200
