Device eth0 does not seem to be present, delaying initialization

Date Posted:03/03/2017

One of our VM didnt come up and we tried to restart network service and we get the following below error.

Device eth0 does not seem to be present, delaying initialization

Normally, this error occurs when there is a mismatch of mac address in the network configuration file or we might have changed the network adapter on the VM.

Resolution:

To fix the issue, we need to delete the file /etc/udev/rules.d/70-persistent-net.rules.

rm /etc/udev/rules.d/70-persistent-net.rules

Additionally, we need to remove the mac address and UUID on the file /etc/sysconfig/network-scripts/ifcfg-eth0

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

Finally, reboot the machine.

reboot

Now, the network will come up automatically. Post your comments incase of any issues.
