Change
network device name from eth1 back to eth0
The interface name of a network
device increases if the mac address of the physical or virtual network card
changes. A common case is if you made a clone of a virtual machine for example
via VMware or KVM or replaced a physical network card in a non virtualized
server.
If it’s a CentOS 6 machine we need
to change 2 files to rename the interface for example from eth1 back to eth0.
One file “70-persistent-net.rules”
is the udev rule for network devices which is located in “/etc/udev/rules.d”
directory.
#
vim /etc/udev/rules.d/70-persistent-net.rules (Edit
this file)
Copy the new mac address to the line
of our eth0 rule and delete the new rule for eth1.
# PCI device 0x15ad:0x07b0 (vmxnet3)
SUBSYSTEM==”net”, ACTION==”add”,
DRIVERS==”?*”, ATTR{address}==”00:50:56:b2:23:e0″, ATTR{type}==”1″,
KERNEL==”eth*”, NAME=”eth0″
Modify the network configuration
located under “/etc/sysconfig/network-scripts/ifcfg-eth0”, and replace the old IP with the new one and
the old mac address with the new mac address.
#
vim /etc/sysconfig/network-scripts/ifcfg-eth0
To be sure everything works fine reboot the
machine.
#
init 6
