I. Causes of obsessive-compulsive disorder

When cloning a VM using VMware workstation, the NIC name is always changed, and it is no longer eth0. This is always uncomfortable. Although it can be used normally, the obsessive-compulsive disorder is very serious and it must be eth0!

2. Configure the eth1 Nic properly

Because no IP address is configured after the cloned VM is opened for the first time, you cannot use Xshell to connect to the VM or install the desktop.

1. When the cloned system is started for the first time, the NIC is not activated. You need to activate it first, and we can see that there is no eth0 Nic.

2. Activate the network adapter eth1

View Nic details

3. The eth1 Nic is configured normally.

# Setup // you can use this command to configure the nic ip address, which is omitted below.

Select Add Device

Add eth1 Nic Information

Save and exit.

4. Restart the network service. eth1 can be used normally.

5. Now you can use the Xshell tool to connect.

#ifconfig eth1Linkencap:EthernetHWaddr00:0C:29:60:15:0F inetaddr:192.168.2.100Bcast:192.168.2.255Mask:255.255.255.0 inet6addr:fe80::20c:29ff:fe60:150f /64 Scope:Link UPBROADCASTRUNNINGMULTICASTMTU:1500Metric:1 RXpackets:60errors:0dropped:0overruns:0frame:0 TXpackets:67errors:0dropped:0overruns:0carrier:0 collisions:0txqueuelen:1000 RXbytes:6219(6.0KiB)TXbytes:10975(10.7KiB) loLinkencap:LocalLoopback inetaddr:127.0.0.1Mask:255.0.0.0 inet6addr:::1 /128 Scope:Host UPLOOPBACKRUNNINGMTU:16436Metric:1 RXpackets:0errors:0dropped:0overruns:0frame:0 TXpackets:0errors:0dropped:0overruns:0carrier:0 collisions:0txqueuelen:0 RXbytes:0(0.0b)TXbytes:0(0.0b)

3. Change the NIC name eth1 to eth0

1. Delete the eth0 configuration file in the system and name the existing eth1 as eth0.

#cd/etc/sysconfig/network-scripts/ #rm-fifcfg-eth0 #mvifcfg-eth1ifcfg-eth0 #viifcfg-eth0 DEVICE=eth0 // Change eth1 to eth0 BOOTPROTO=none NETMASK=255.255.255.0 TYPE=Ethernet HWADDR=00:0c:29:60:15:0f IPADDR=192.168.2.100

2. Delete the first device in the configuration file, and change the name of the second device to eth0. The MAC address must be consistent with that in the NIC configuration file.

#cd/etc/udev/rules.d/ # Vi70-persistent-net.rules // status not modified #PCIdevice0x8086:0x100f(e1000) SUBSYSTEM== "net" ,ACTION== "add" ,DRIVERS== "?*" ,ATTR{address}== "00:0c:29:69:90:83" ,ATTR{ type }== "1" ,KERNEL== "eth*" ,NAME= "eth0" #PCIdevice0x8086:0x100f(e1000) SUBSYSTEM== "net" ,ACTION== "add" ,DRIVERS== "?*" ,ATTR{address}== "00:0c:29:60:15:0f" ,ATTR{ type }== "1" ,KERNEL== "eth*" ,NAME= "eth1" # Cat70-persistent-net.rules // status after modification #PCIdevice0x8086:0x100f(e1000) SUBSYSTEM== "net" ,ACTION== "add" ,DRIVERS== "?*" ,ATTR{address}== "00:0c:29:60:15:0f" ,ATTR{ type }== "1" ,KERNEL== "eth*" ,NAME= "eth0"

3. restart the system and view the information.
