Can't get virtual NIC to work.

I'm having trouble getting a virtual interface to work on a CentOS machine. I have followed the instructions in the support documents to no avail. I have created the ifcfg-eth1 file but when I try to restart the network services, I get the following output.

[root@antlet10 network-scripts]# systemctl restart networkAuthorization not available. Check if polkit service is running or see debug message for more information.Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.

When i run journalctl -xe, I see the following entries:

Mar 30 15:44:44 antlet10 network[20271]: Bringing up interface eth1: ERROR : [/etc/sysconfig/network-scripts/ifup-eth] Device eth1@if26 does not seem to be present, delaying initialization.

Mar 30 15:44:44 antlet10 /etc/sysconfig/network-scripts/ifup-eth[20442]: Device eth1@if26 does not seem to be present, delaying initialization.

Why can't it find my eth1 interface.


Hey @gregh825,

I created a CentOS-7.1 - LXC, created a vNIC in antMan, started the antlet, and  sshed in.


cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1

Then edited `ifcfg-eth1` to `DEVICE=eth1`.

Now `service network restart` and I can see the new ip on eth1 when I run an ifconfig.

You can then update the OS if you like.


Are you perhaps using a different CentOS than the templates or not using the LXC version?


lancem and gregh825 have reacted to this post.

That fixed it.
