libvirt users - Dec 2011 - Adding a public static IP address to the guest

Hello,

The host runs on CentOS 6. I have installed a guest, CentOS 5.7, using 
libvirt.

I am having difficulty understanding how to assign a public static IP 
address to the guest. From what I understand by reading the Wiki, I 
think I require routed mode.

The ISP has provided a 'portable' IP routed to the VLAN of our servers. 
I want to assign this IP address to the guest.  From the virtual machine 
hardware details window, I see that "Virtual network 'default' :
NAT" is
selected for the source device field.

Can someone offer a helping hand and instruct and educate me on how to 
proceed from here?

Thanks.

The easiest way that I found to do this is to configure a bridge on your 
physical host's NIC, and then configure the KVM guest to use the shared 
device.

I used the following general howto to originally get this set up:
