Hi,
Thoght of sharing this with u will be handy
I was upgrading my workstation yesterday, only the case and harddisks remained the same. Almost everything went well, even new init ramdisk wasn't required, but I was stuck on networking for a while. And the problem was called "eth0_rename". After querying google it was clear that this is the result of "network device persistency" feature and the cause is different MAC address assigned to the new eth0 device. Solution was easy - remove the old records from /etc/udev/rules.d/70-persistent-net.rules
And add some custom udev mac binding rules like below
cat /etc/udev/rules.d/10-redhat-custom-net.rules ##Realtek KERNEL=="eth*", SYSFS{address}=="00:16:3e:66:20:c7", NAME="eth0" ###Accton KERNEL=="eth*", SYSFS{address}=="00:16:3e:7e:a1:9c", NAME="eth1"

Hi
I change eth1 from realtek to dlink but the centos is showing eth2 instead of eth1
In another version of linux, I can change 70-persistent-net.rules but
I check /etc/udev/rules.d/70-persistent-net.rules but it doesn't have the file 70-persistent-net.rules
please help
Thank you
