Hello,
I have a CentOS 6 VM on a CentOS 6 host. This VM has two ethernet interfaces, eth0 and eth1. It was working nice. All of a sudden eth1 stopped working as expected. Kernel started to give the message below:
kernel: udev: renamed network interface eth2 to eth2-eth1
There is no any eth2 or eth2-eth1 in /etc/sysconfig/network-scripts/. I really don't know where it is coming from.
Your eth1 is being automaticaly renamed to eth2-eth1 for some reason. Have you changed anything in config(s) connected to eth1?
Are name and device name in ifcfg-ethX consistent? Have you reshufled your configs and left loose end somewhere?
Do you maybe have NetworkManager still active?
Thank you for the responses.
There is no NetworkManager installed.
Perhaps I should give some more info. It is a two-gateway machine. I have following lines in my rc.local:
# routing and default gateway for each interface ip route add 10.0.0.0/24 dev eth0 src 10.0.0.32 table T1 ip route add default via 10.0.0.11 table T1 ip route add 192.168.2.0/24 dev eth1 src 192.168.2.2 table T2 ip route add default via 192.168.2.1 table T2 # regular routes ip route add 10.0.0.0/24 dev eth0 src 10.0.0.32 ip route add 192.168.2.0/24 dev eth1 src 192.168.2.2 # default gateway ip route add default via 10.0.0.11 # rules ip rule add from 10.0.0.32 table T1 ip rule add from 192.168.2.2 table T2
But again, the system was working before fine. The problematic interface is 192.168.2.2 (eth1).
In network-scripts directory, I have 2 eth configuration files, nothing else (apart from lo of course).
eth0: DEVICE="eth0" NM_CONTROLLED="yes" ONBOOT=yes HWADDR=52:54:00:E0:5A:C5 TYPE=Ethernet BOOTPROTO=none IPADDR=10.0.0.32 PREFIX=24 DNS1=127.0.0.1 #DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System eth0" UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03 PEERDNS=no

Thank you for your support.
