I am trying to stop my kickstart CentOS install prompting me for TCP/IP information. After I click through this prompt (keeping IPv4 and IPv6 to their defaults) the installation continues and completes just fine. Below is my kickstart file:

My kernel arguments are in this following virt-install command that I use to start the install:

virt-install -n zabbix -r 2048 --vcpus=2 -l http://mirrors.kernel.org/centos/6/os/x86_64 --disk /dev/vg_inf1/zabbix --network bridge=br85 --initrd-inject=/home/ashinn/vm_kickstart --extra-args "ks=file:/vm_kickstart SERVERNAME=zabbix" --autostart

During the install, I can pull up a console on the second terminal and verify the contents of /tmp/network.ks are:

network --onboot=yes --bootproto=dhcp --ipv6=auto --hostname=jenkins2.mydomain.com

Why might Anaconda be prompting for the TCP/IP settings when they are already set to DHCP?

  • Can you check if the settings in /tmp/network.ks are correct?

The Configure TCP/IP prompt will always display if DHCP fails for any reason. Try specifying the specific ethernet interface you want to use with --device=ethX.

I ran into this issue on a machine that was set up to DHCP from eth2 and my standard kickstart config used eth0.
