Nic failure after OracleVM system Clone

Source: Internet
Author: User

Oracle VM is good to use, but every time you Clone the system, the eth0 NIC will arrive at the new OS and use ifconfig to check that eth1 is found. It's strange to change the/etc/sysconfig/network-scripts/ifcfg-eth0 configuration file. Solution 1:

In the GUI menu, delete eth0 and use the eth1 one.

Solution 2:

Modify the ing relationships in the 70-persistent-net.rules file. Change the NIC corresponding to eht0 in the 70-persistent-net.rules file to the MAC address of the new OS Nic. Delete unnecessary ones. The file path is as follows. Oracle Linux:/etc/udev-post/rules. d/70-persistent-net.rulesCentos:/etc/udev/rules. d/70-persistent-net.rules

Restart your computer.
