[Xen-users] Creating network bridge without IP address

[Zoltan Lippai <zoli@xxxxxxxxxx>]

Hi everyone!

I have the following setup:

domain0
|-domU1
|-domU2
|-domU3

I am running this with libvirt on a XEN server. Right now the server is 
connected to our office network, but later it will be in a hosted environment. 
I need domU1 and domU3 to have a public IP, and all of the domUs and the dom0 
should have an internal IP address to communicate with each other. So this is 
what I would like to achieve:

domain0 
   192.168.122.1
|-domU1
   192.168.122.2
   192.168.1.45 (later this will be changed to the public IP)
|-domU2
   192.168.122.3
|-domU3
   192.168.122.4
   192.168.1.46 (this will also be changed to a public IP)

On domain0 I have the following network interfaces:

br0       Link encap:Ethernet  HWaddr 54:04:a6:66:c4:be  
          inet addr:192.168.1.44  Bcast:192.168.1.255  Mask:255.255.255.0
virbr0    Link encap:Ethernet  HWaddr 52:54:00:fe:88:0c  
          inet addr:192.168.122.1  Bcast:192.168.122.255  Mask:255.255.255.0

This way everything is working fine, except that I don't want domain0 to have a 
public IP (which is 192.168.1.44 in this case)

So is it possible somehow to setup br0 on domain0 without it having an IP 
address?

Thank you,
Zoltan Lippai
