After VMWARE replicates the virtual machine, you need to reconfigure the network card (CENTOS 6)
After copying a virtual machine using VMWARE, you will encounter the situation that the network card is not available. At this time, you need to manually reconfigure the network card.
The following is the configuration of the network card for REDHAT 6 (CENTOS 6) version. For 7 version, please see another blog.
Procedure:
1. View the MAC address of the current virtual machine
Ip addr
[root@node1 rules.d] # ip addr
1: lo: mtu 16436 qdisc noqueue state UNKNOWN
Link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
Inet 127.0.0.1/8 scope host lo
Inet6:: 1/128 scope host
Valid_lft forever preferred_lft forever
2: eth2: mtu 1500 qdisc pfifo_fast state UP qlen 1000
Link/ether 00:0c:29:5c:a5:f5 brd ff:ff:ff:ff:ff:ff
Inet 192.168.159.160/24 brd 192.168.159.255 scope global eth2
Inet6 fe80::20c:29ff:fe5c:a5f5/64 scope link
Valid_lft forever preferred_lft forever
2. Modify / etc/udev/rules.d/70-persistent-net.rules
Vi / etc/udev/rules.d/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 0x8086:0x100f (e1000)
# SUBSYSTEM== "net", ACTION== "add", DRIVERS== "? *", ATTR {address} = = "00:0c:29:09:90:84", ATTR {type} = = "1", KERNEL== "eth*", NAME= "eth0"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM== "net", ACTION== "add", DRIVERS== "? *", ATTR {address} = = "00:0c:29:5c:a5:f5", ATTR {type} = = "1", KERNEL== "eth*", NAME= "eth2"
Comment out the red part
3. Rename the Nic configuration file
Cd / etc/sysconfig/network-scripts/
Mv ifcfg-eth0 ifcfg-eth2
Here, change the eth* to the same as in the 70-persistent-net.rules file, and pay attention to the contents of the ip addr.
4. Edit the network card configuration file
Vi ifcfg-eth2
DEVICE= "eth2"
BOOTPROTO= "static"
HWADDR= "00:0C:29:5C:A5:F5"
IPV6INIT= "yes"
NM_CONTROLLED= "yes"
ONBOOT= "yes"
TYPE= "Ethernet"
UUID= "e618ec6a-8bb0-4202-8fe6-54febd0f8c76"
IPADDR=192.168.159.160
NETMASK=255.255.255.0
GATEWAY=192.168.159.1
Modify the red part.
In the first line, modify eth* to be the same as in the 70-persistent-net.rules file. Pay attention to the contents in ip addr.
The second line is changed to static IP
The third line is modified to be the same as the MAC address found by ip addr
The last three lines are IP address, subnet mask and gateway, all of which should be configured. If there is a DNS, you can also set it.
DNS1=192.168.159.3
DNS2=192.168.159.4
5. Restart the network card
Service network restart
