CentOS Linux Solution device eth0 does not seem to be present

installed in the KVM CentOS Linux systems. Restart the system after the power outage, the network suddenly does not pass.

Ifconfig-a|more didn't see eth0. Then restart the Network service, the error is as follows:

Failure phenomena:

Service Network restart

Shutting down loopback insterface: [OK]
Bringing Up loopback insterface: [OK]
Bringing up interface Eth0:device eth0 does no seem to be present,delaying initialization. [FAILED]

Workaround:

1. First, open the/etc/udev/rules.d/70-persistent-net.rules

Vi/etc/udev/rules.d/70-persistent-net.rules:
Then log down the MAC address of the eth1 NIC.

2. Open/etc/sysconfig/network-scripts/ifcfg-eth0

Vi/etc/sysconfig/network-scripts/ifcfg-eth0:

Change device= "eth0" to Device= "eth1",
Change the current hwaddr address of the eth0 to the MAC address of the eth1 NIC that has been recorded. hwaddr= "XX:XX:XX:XX:XX:XX".

3. Finally, restart the network

Service Network restart
Or

/etc/init.d/network restart

In this way, the network service is normal.
