Basic settings: Modify the NIC device name.

The VM uses the cloned Vm and the NIC name is eth1. To change eth1 to eth0, follow these steps:

1. View the MAC address of eth1
   

   Ifconfig

   For example, eth1: 00: 0C: 29: 74: F2: 99

2. Change the MAC address of/etc/sysconfig/network-scripts/ifcfg-eth0 to the MAC address of eth1

   Since the VM is cloned, there is no eth1 file under the network-scripts directory, there is a ifcfg-eth0 under the directory, the modification is as follows:

Hwaddr is changed from the original Mac to the MAC of eth1 and saved.

Device = eth0

Hwaddr = 00: 0C: 29: 74: F2: 99

Onboot = Yes

Ipaddr = 192.168.198.10

Bootproto = none

Netmask = 255.255.255.0

Type = Ethernet

Gateway = 192.198.198.2

3. Modify the/etc/udev/rules. d/70-persistent-net.rules file.

ATTR {address} and name fields

[[Email protected] rules. d] # Cat 70-persistent-net.rules

# This file was automatically generated by the/lib/udev/write_net_rules

# Program, run by the persistent-net-generator.rules rules file.

#

# You can modify it, as long as you keep each rule on a single

# Line, and change only the value of the name = key.

# PCI device 0x1022: 0x2000 (pcnet32)

# Subsystem = "Net", Action = "add", drivers = "? * ", ATTR {address} =" 00: 0C: 29: 55: 61: 94 ", ATTR {type} =" 1 ", kernel = "ETH *", name = "eth0"

# PCI device 0x1022: 0x2000 (pcnet32)

Subsystem = "Net", Action = "add", drivers = "? * ", ATTR {address} =" 00: 0C: 29: 74: F2: 99 ", ATTR {type} =" 1 ", kernel = "ETH *", name = "eth0"

[[Email protected] rules. d] #

4. restart the system
