on your OS either LION or SNOW LION discs, you have will the drivers for windows regardless if its a virtual machine or not, you need to install that disc on your virtual machine and *update* your drivers to have full compatibly. The disc with the drivers are DISC 1.
You need to install Bootcamp drivers in Windows. They can be downloaded and extracted to a USB/Disk using the Boot Camp-assistent found in Help Utilities.
