To create a Linux virtual machine nic with a template eth0 invalid workaround

Problem Description:
After deploying the system using the Linux virtual machine template, Ifconfig–a was used, no eth0 was found, eth1 was found, there was a ifcfg-eth0 file under/etc/sysconfig/network/, but no ifcfg-eth1 files.

Solution:
Method One: When you create a template virtual machine, the 70-persistent-net.rules file is deleted before it is created as a template VM.
Method Two: Modify the 70-persistent-net.rules file
Open/etc/udev/rules.d/70-persistent-net.rules File

PCI device 0x1022:0x2000 (Pcnet32)

subsystem== "NET", action== "Add", drivers== "? *",
attr{address}== "00:0c:29:50:xx:xx", attr{type}== "1", name= "eth0"

subsystem== "NET", action== "Add", drivers== "? *",
attr{address}== "00:0c:29:36:xx:xx", attr{type}== "1", name= "eth1"
Remove the eth1 configuration and replace the MAC address of eth0 with the Eth1 MAC address
Restart the NIC
