Device "eth0" does not exist

In CentOS, network interfaces are named differently. So they aren't called eth0 or eth1, but rather have names like eno1 or enp2s0. (Source.)

Run ip addr to see how these interfaces are named on your system.

These names are defined in /etc/sysconfig/network-scripts/ifcfg-<iface>. You can change their names if you really wanted to, but I don't recommend it.
