Kickstart Ethernet Devices
(2014-02-17)
Problem
the specified interface eth0 does not exist
Solution
In the general case, specify your network configuration without specifying a specific device:
#network --onboot yes --noipv6 --device=eth0 --bootproto=dhcp
network --onboot yes --noipv6 --bootproto=dhcp
It should pick the first device it finds, which is probably the device you want since it is the device that anaconda picked to get you that far.
For system-specific kickstarts, specifying the device to use is always safest:
network --onboot yes --noipv6 --device=em1 --bootproto=dhcp
