Solution to NIC conflict in the replication Virtual Machine

Deviceeth0doesnotseemtobepresent and delayinginitialization often occur during Virtual Machine Replication.

At this time, you need to do two things.

1. vi /Etc/sysconfig/network-scripts/The ifcfg-eth0ifcfg-eth0 configuration file saves the previous MAC address, the line is deleted in the restart Nic
2./etc/udev/rules. d/70-persistent-net.rules after deletion, restart the machine because the file is bound to the NIC and mac address, so after the NIC is changed, the MAC address is changed, so it cannot be started normally, you can also directly edit this configuration file to replace the NIC and mac address in it. However, if you delete and restart the configuration file, it will automatically generate one.
