Solve the problem that the network adapter eth0 cannot be found for the centos virtual machine deployed on esxi with a virtual machine Template

1. The problem is similar to the problem where the NIC cannot be found after the VM is cloned.

2. Modify the host name hostname

Modify the/etc/sysconfig/Network File

3. Delete the hwadd row in/etc/sysconfig/network-scripts/ifcfg-eth0 or install the newly assigned MAC address modification for the NIC in the VM properties. Modify static IP addresses at the same time

4. Delete the/etc/EDEV/rules. d/70-persistent-net.rules file.

5. restart the system reboot.
