After cloning is complete, enter the virtual machine and set ip
Execute the command (ifcfg- added according to your own situation):
vim /etc/sysconfig/network-scripts/ifcfg-ethxxx

Related introduction (according to your actual situation):
DEVICE=eth0
HWADDR=00:0C:29:EB:72:FA
TYPE=Ethernet
UUID=af9a3043-12d7-4dd3-9948-9d8de30d8d32
ONBOOT=yes (whether to start after boot,yes）
NM_CONTROLLED=yes
BOOTPROTO=static(Is the ip address dynamically obtained or static, static?)
IPADDR=192.168.5.104(ip address, this ip address must not be set to be the same as the gateway IP)
NETMASK=255.255.255.0(Subnet mask)
GATEWAY=192.168.5.2 (default gateway)
Then restart the network card
service network restart
Check if the ip address has changed
ip addr

You can see that the ip address has changed and the mac address is different from the one we cloned. At this time, the cloning is complete.
You can ping Baidu to try the network, then ping your previous virtual machine,
ping baidu.com
If the ping fails, you can try the following operations.
Delete the file bound to the Linux physical address (the file will bind the physical address to the IP after the operating system restarts and generate the physical address). If it is not deleted, the operating system will always be bound to the cloned physical address;
rm -rf /etc/udev/rules.d/70-persistent-net.rules
If it still doesn't work, check whether the mac address is the same as the mac of the cloned machine. If it is the same, change it.
