Checklist

• Enterprise Linux 6/7

• On the “Welcome to CentOS” screen, highlight “Install or Upgrade an existing system” and press “tab” to edit boot options.
• After “vmlinuz initrd=initrd.img”, append:

  ks=nfs:<nfs-server-ip>:/ISO/centos6.7-dvd/centos6-ks.cfg ksdevice=eth0 ip=x.x.x.x netmask=x.x.x.x gateway=x.x.x.x nameserver=<dns-ip>

• Note: This can be pasted into the console by using most KVM menus. (Keyboard > Send Text to Target… > Paste in text > click Ok)

The following kickstart file performs a network install of CentOS 6 minimal, on /dev/sda, with LVM, and reboots after installation.

Modify the IP addresses in the “CUSTOMIZE” sections and paste in an encrypted root password before using.
