[all variants] Internet not working on Virt-manager guest

Hi

I am using Ubuntu 12.04.

My laptop gets internet from a wireless router which is connected to a modem.



I already have a full working Centos 6 vm with Virtualbox which has working internet.

I am trying to use Centos 6 in a Virt-manager virtual machine with KVM.

I have installed created and installed Centos 6 with Virt-manager and everything seems to be working except the internet.

On both Virtualbox and Virt-manager I am using NAT but internet is only working on Virtualbox.

I have tried selecting different NAT device models but internet still didn't work.

I have attached screenshots of the my Virtualbox and Virt-manager network configs.
