Hi All:

        when I reinstall os by cobbler on one  machine which network interfaces config to bonding 0, I saw this error:

https://github.com/cobbler/cobbler/issues/1478

I don't know why one network interfaces  do not restore to original  mac  after reboot ;  

final , I unplug one network interface and all work well.

and is there other way resolve this problem ?

and is there a way   to  echo friendly error  message?   like “opps!  your network interface has same mac address , please check.”



thank you
