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,
virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:35 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:9143 (8.9 KiB)
It's an virtual brigde created by xen..
It's used by your xen DomainU's..
Cheers,
Bart

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