why is eth0 not showing up?

[jpsebasti]

Hi folks,

I'm using the latest Virtual Box VM software. I've installed O Enterprise Linux 6. This is on m laptop. My laptop uses a wireless network connection. I want to make the wireless network card work in my OEL 6 virtual host when it boots up. In VirtualBox, I've configured the Network to be Bridged and selected the Wireless device. I then click the Advanced and select PCnet-FAST III (Am79C973) for Adapter type.
When I boot up the linux host, I only have an lo network adapter. There is no eth0. I don't have a lot of experience with this so I'm wondering if I am doing something wrong or if this is expected and I have to then setup an eth0 device once the OS is booted.

Any help is greatly appreciated
