*centos Virtual Machine Network connection: Bridging mode *
Virtual machine cloning can cause network connection not on: (Cause the new Mac and NIC configuration does not correspond)
Problem Resolution (perform the following steps in the clone machine):
Vi/etc/udev/rules.d/70-persistent-net.rules (if you are fully cloned, this file should contain eth0 and eth1, tested Vmware,virtualbox)
Delete the eth0 configuration, keep only eth1, record the MAC address of the configuration, and rename eth1 to Eth0, where the eth1 MAC address is recorded for the following.
Vi/etc/sysconfig/network-scripts/ifcfg-eth0
Change the MAC address in the configuration to the Mac that was recorded in the previous step, that is: eth0 (formerly Eth1) Mac in the corresponding 70-persistent-net.rules file
Reboot restart machine ~ ~ ~
