[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,

It comes from virtual bridge (if you use vm,xen ...).

[CentOS] What is vibr0 Network interface and what is it used for
My first guess would be a Virtual Bridge 0 interface. Did you decide to install Xen during the 5.2 installation? If so then it would automatically start up its network bridge to connect your Xen Guests to your local network (if you mapped the Xen Guest interface to work on this bridge).
