A problem with creating a cloned virtual machine in VMware CentOS causes the NIC device to fail to start

First, preface

When creating a clone virtual machine, if the template virtual machine is not configured beforehand, it will cause the network card device to not start the problem (error is as follows).

Bringing up interface Eth0:device eth0 does not seem to be present, delaying initialization

Second, the solution

1. Modify the NIC configuration file/etc/sysconfig/network-scripts/ifcfg-eth0

Delete the UUID line, because the MAC address of each card is not the same, so the UUID is not the same.

Delete or modify the MAC address of a cloned virtual machine

2. Empty the contents of the "/etc/udev/rules.d/70-persistent-net.rules" file or delete the file "Rm-f/etc/udev/rules.d/70-persistent-net.rules"

>/etc/udev/rules.d/70-persistent-net.rules

echo ">/etc/udev/rules.d/70-persistent-net.rules" >>/etc/rc.local

Cat/etc/rc.local
