My hair is in fire trying to make Internet connection work in guest OS.

I have Ubuntu 12.10 machine with VirtualBox 4.1.18 installed from Ubuntu Software Center

I set PC-BSD and FreeBSD to work as GuestOS

Now both GuestOS have no internet connection. I have tried different methods like:

sudo apt-get install dnsmasq and changed the /etc/dnsmasq.d/network-manager config to add except-interface=lo which blocked all of my internet connections.

I also added dns-nameservers 8.8.8.8 8.8.4.4 to /etc/network/interfaces and restart the network-manager.

Finally I did VBoxManage modifyvm "PC-BSD" --natdnshostresolver1 on and VBoxManage modifyvm "PC-BSD" --natdnshostresolver1 on but to no avail.

I have already tried NAT and different options in Bridged too

I still don't have internet connection in GuestOS, is there anyway I can fix this ? As far as I think the problem is in Ubuntu 12.10 for not sharing the internet, but I don't know how to fix this.

After trying this and that, I fixed the problem as follows.

sudo gedit /etc/network/interfaces

I commented out auto lo and added auto eth0. After that I did

sudo service network-manager restart

Now networking works in all VirtualBox guest OSes.

I don't know how this works, but in my Kubuntu 12.04 the network interfaces was set to eth0, so, I thought of giving it a try, and it works.

Edit:

As per jdthood suggestion, I had to put back the lo for network manager to work properly. After few days when I restart my computer, it started saying Could not detect network and I uncommented out lo, so, now I have both

auth lo

auth eth0

and everything is working fine.
