Error after Linux startup network: Device eth0 does not seem to be present, delaying initialization

Issue background:

After you deploy the OVF template in vsphere Client, start the network prompt for Linux: device eth0 does not seem to be present, delaying initialization

The device eth0 is not ready for deferred initialization:

The problem is that the MAC address in the exported OVF template is the source system's Mac (the profile is the configuration file for the source system (the system that exported the OVF template), and the system MAC address after the OVF deployment has changed, so the initialization fails with the following workaround:

1.Vi/etc/sysconfig/network-scripts/ifcfg-eth0
Ifcfg-eth0 the previous MAC address in the configuration file, delete this line to restart the NIC
2./etc/udev/rules.d/70-persistent-net.rules Restart the machine after deletionbecause this file is bound to the network card and MAC address, so change the network card after the MAC address has changed, so it can not start normally, or directly edit the configuration file inside the network card and MAC address modification by corresponding, but so much trouble, the direct deletion of restart, it will automatically generate a.
