Ubuntu – No internet connectivity in virtual-box with both Host and Virtual OS being 12.04

12.04network-bridgevirtualboxvirtualbox-networking

I have Precise 12.04 installed as the host OS. In VirtualBox,I also have installed 12.04.

I am not able to connect the Virtual 12.04 to the host internet. I have tried selecting all the available options in the network adapters (NAT,Host only,Bridge,etc), but non of them is working. In the some options some stuff has to be entered manually, which I do not know what to enter.

Where am I going wrong in the settings?

The NAT connection needed to be selected with the hardware being:

AMD PCNet FAST III (Am79C973, the default)

This works with almost any OS (as mentioned on the Virtualbox help page). The Intel setting for some reason did not work.

For Network setups with heavy router settings, you may have to use Bridged option with "PCNet FAST III" as the default.

Ubuntu – Problems with NAT Adapater since upgrade to Ubuntu 12.10

Known bug of (K)Ubuntu 12.10. Try the following two command lines :

VBoxManage modifyvm "name" --natdnshostresolver1 on
VBoxManage modifyvm "name" --natdnsproxy1 on

if that does not work, install virtual box 4.2 :

Uninstall virtualbox from your computer

sudo apt-get remove virtualbox

also uninstall the guest-addition iso as the 4.2 version contains a new one :

sudo apt-get remove virtualbox-guest-additions-iso

Download and install virtual box 4.2

echo "deb http://download.virtualbox.org/virtualbox/debian $(lsb_release -sc) contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list
wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -
sudo apt-get update
sudo apt-get install virtualbox-4.2

When running virtualbox the first time it will ask you to update guest-addition module with the one downloaded.

Enjoy !
