10 How to fix “Device eth0 does not seem to be present, delaying initialization.”

After clone the VM within Virtual box, I receive the error message “

Device eth0 does not seem to be present, delaying initialization.” when start the network service.


The /etc/sysconfigu/network-scripts/ifcfg-eth0 does exist. The issue is that the network device eth0 is non longer exist. The VM clone processes create the new device eth1.

The device file is at /sys/class/net.

ip link show


We can rename the device by using the up command.

ip link set eth1 name eth0


After the device being renamed, we can successfully bring up the network interface.


  1. I tried to rename but 'RTNETLINK answers: Device or resource busy '
    how can i fix?
    Please help me

  2. hi i THOUGHT i have same problem as you..
    but when i saw the result of command, i got "Device "eth0" does not exist."

    but after that, my network is totally broken.
    now.. i'm eager to turn it back..
    please, any advice will be appreciated.
    thank you

  3. Delete networking interface rules file so that it can be regenerated and reboot your CentOS system.

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

  4. Try the below command it worked for me
    # ifdown eth0
    # rm /etc/sysconfig/network-scripts/ifcfg-eth0
    # rm /etc/udev/rules.d/70-persistent-net.rules
    # reboot

  5. thank you for replying.
    fortunately i've solved the problem somehow..
    I can't be sure but as my memory, I might setup another CentOS machine and copied the network interface files
    or.. I just typed "setup" and reset the configuration.

    anyway, again, thank you for your replies you guys
