[How to Solve] Device eth0 does not seem to be present

For the virtual machine clone or template deployment machine, the network card will have the following problems:

service network restart
Shutting down loopback insterface: [ OK ]
Bringing up loopback insterface: [ OK ]
Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization. [FAILED]

Solution:

Open/etc/udev/rules.d/70-persistent-net.rules, check the MAC address of eth1, and then open/etc/sysconfig/network scripts/ifcfg-eth0 after recording

Then, eth0 is replaced by eth1 and the original MAC address is changed

Just restart the network
