Onderwerp: [CentOS] What is vibr0 Network interface and what is it used for

Hello,

I have see that my machine have an interface that named virbr0. I have 
no idea what is it and what it using for ? I am not configured any IP 
address for it but I see it had an IP address and see it listed in 
firewall config.
Can anyone give me an explanation about this or point me to a document 
that describe it ?

My machine running CentOS 5.2 and do not have internet connection from 
the installation time.

Thanks,
