There's a new server that is assigned 5 IP addresses. I want to use Xen to run several VMs with various services. 

This is my first attempt to install Xen, I use [this tutorial](http://www.howtoforge.com/virtualization-with-xen-on-centos-6.3-x86_64-paravirtualization-and-hardware-virtualization) as a guideline. Stuck in the very beginning: they talk about replacing a single ip on an eth0 with a bridge `br0`. My server has 5: `eth1` and 4 aliases `eth1:1` .. `eth1:4`. 

How should the network config look like?

1. bridge that replaces eth1 completely, and then 4 aliases added to the bridge?
2. bridge can only replace a single IP out of the 5?

Pardon my lame questions, first time in this forest.
