Eth0 not found on Linux system after virtual machine cloning

Workaround:

1. After removing the/etc/udev/rules.d/70-persistent-net.rules, restart the machine. 70-persistent-net.rules This file determines the binding of the network card to the MAC address, after importing the existing virtual machine, but the MAC address of the NIC has changed, so the system does not think the network device exists.

2, after such processing eth0 still can not start normally, need to/etc/udev/rules.d/70-persistent-net.rules file final modification "eth1" for "eth0", and then/etc/sysconfig/ The MAC address in the Network-scripts/ifcfg-eth0 is modified to the address recorded in the/etc/udev/rules.d/70-persistent-net.rules file, and then the machine restarts, eth0 can start normally.
