[libvirt-users] removing virbr0

[Peter Steele]

I do something similar, generating a custom image that gets installed on 
multiple systems. I just have a startup script in my image that runs 
"virsh net-undefine default" during boot-up. If you are creating your 
own image, you should be able to insert something similar in your 
start-up process.
