MAC address exception handling by Linux migration under virtual machine

MAC address exception handling by Linux migration under virtual machine

Linux cannot enable NIC: Device eth0 has different MAC address than expected,ignoring resolved

Encountered an error: On Linux, the network card cannot be successfully started,

When we activate a network card, the following error is indicated.

Cannot activate network device eth0!

Device Eth0 has different MAC address than expected, ignoring

Cause of the problem:

The network card in the configuration file has a MAC address that does not match the actual NIC address.

You can compare the MAC address in the Ifconfig results with the MAC address in the configuration file below.

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

(Note: The configuration file may not call this name, it may also be ifcfg-***, such as for my system, I modified called ifcfg-eth0.bat)

Workaround:

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

Edit the MAC address.

I was on the virtual machine above the problem,

I modified the MAC address in the configuration file to the MAC address in the ifconfig results.

Problem solved, the network card can start from the new.

[Network configuration=>edit=>ethernet Device=>bind to MAC address] displays the MAC addresses,

Also becomes the correct MAC address.
