CENTOS7 Virtual Machine Network configuration after cloning (restart network failed solution)

The clone source's Centos7_1 network address is 192.168.140.11, and I want to change the network address of the cloned centos7_2 to 192.168.140.12. Two places need to be changed: The network configuration of the virtual machine and the Centos7_2 configuration file.
If you don't know how to configure a static address, you can view the previous article:
1. Configure Virtual Network Editor
2. Set static IP
3. Use Xshell to connect virtual machine 1 cloned virtual machine configuration 1.1 edit-> Virtual Network editor-> Select vmnet8-> change settings-> select Vmnet8->nat Settings

1.2 Adding NAT mappings

The address I set here is 192.168.140.12.

2 cloned CENTOS7 configuration

The NIC name is ens33 after the ifconfig command is executed, but the network profile is still/etc/sysconfig/network-scripts/ifcfg-eno16777736. If you perform systemctl restart network now, the job for Network.service failed because the control process exited with error code will appear. Change the original network configuration filename ifcfg-eno16777736 to the name of the network card you queried (mine is ENS33): MV ifcfg-eno16777736 Ifcfg-ens33. Modify the Ifcfg-ens33 content to change the value of device and name to ENS33. Notice I don't have a MAC address set up here. Modify the IP address to 192.168.140.12.
Reboot the network, systemctl Restart Network, found the boot was successful. Ping the following Baidu – success.
3.xshell to connect

New Xshell link (direct with static IP link):

The clone source system is then opened and the link test is performed.
Links were successful.
