Device eth0 has different MAC address than expected, ignoring.

If you see: -

Shutting down loopback interface: [ OK ]
Setting network parameters: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Device eth0 has different MAC address than expected, ignoring.
[FAILED]

then you may be seeing the same problem as me; am using a prebuilt VMware image of Red Hat Enterprise Linux (RHEL), where my colleague had hard-coded the MAC address of his virtual Ethernet adapter into the configuration.

The solution is simple - edit /etc/sysconfig/network-scripts/ifcfg-eth0 and remove the line: -

HWADDR=00:0C:29:2E:C9:6A

Alternatively, use the graphical network configuration tool to do the same.

Bonne chance

Thanks for the tip. I used the graphical Network Configuration tool to modify this entry, instead of removing it: click Edit, then Hardware tabs, and click on the Probe button next to the "Bind to MAC address" entry.
