I use qemu-kvm for the most part, but I have used virtualbox. How about a listing of your network via ifconfig?
Â*
Also, do you have only one nic in the system?

Yes, single nic.

To test, I installed virtualbox 4.1.2x on an 11.10 system that has two nics:
Â*
sudo apt-get install virtualbox
Â*
Then, just for grins, I downloaded and installed PC-BSD 9, 32 bit version in virtualbox. Works perfectly, and I can install updates, so the network is working using the default NAT setting.
Â*
In the Advanced network settings, it defaulted to an Intel Pro/1000 nic, with Cable Connected checked.
Â*
I chose not to install the recommended add-ons, but one of the add-ons is vde2, which seems to be related to bridged networking. But again, this wasn’t needed to get it to work.

Â*
Oh, are you saying you want the guest to connect directly to your lan? You wish it to obtain an IP address from the lan?
Â*
If that’s the case, a bridge is what you are looking for.

I recommend using virtualbox version: note that VirtualBox is up
to version 4.1.8 & your's is at 4.1.2. Here are the change logs so you
can see the difference:
https://www.virtualbox.org/wiki/Changelog

Start here:
https://www.virtualbox.org/wiki/Downloads
[note the VirtualBox 4.1.8 Oracle VM VirtualBox Extension Pack]
https://www.virtualbox.org/wiki/Linux_Downloads
[read the entire page - & be sure to 'combine downloading and registering'.

If you still have problems, check:
https://www.virtualbox.org/wiki/End-user_documentation
https://www.virtualbox.org/manual/UserManual.html
https://www.virtualbox.org/manual/ch06.html
And of course:
