Hi!!

I don't know how i have modified the interface name br0 by br1, but it's do, and my virtual machine ( on KVM) can not to be launch, because virt-manager know br0 and not br1....


How can i change the interface name, i tried :


#ifconfig br1 down
#nameif
#ifconfig br0 up
ifconfig

But it don't work!!!!

Maybe i could do that inside KVM but where exactly ?

I think when I last did any configuration changes like this I did so via
Yast. A bridge device isn't a hardware device so it should all be
configurable. The config files are probably the ones stored in
/etc/sysconfig/network

Hi cmigroup,

bridges, if set up via standard mechanism, receive their "interface" name from the corresponding part of their configuration file - as "ab" pointed out, look at /etc/sysconfig/network/ifcfg-br* to see if the bridge config file somehow got named "ifcfg-br1" and if so, rename it to "ifcfg-br0" after bringing down br1...

Regards,
Jens
