Hi all....
i'm looking for a system for setting dual monitors on my guest linux Centos 3.9. I'know that is very old OS but i need to use it....

Host System Windows 7; 2 monitor
Virtualbox 4.2.10 r8414

Guest System Centos 3.9 (Kernel 2.4.21-50 supported by virtualbox) configurated with 2 monitors.
Guest addition successfully installed.

from lspci, the only graphic adapter is:
00:02:0 VGA compatible controller :Innotek Systemberatung GmBh Virtualbox Graphics Adapter
