Adachinですっ。
KVM内でゲストサーバ構築時(CentOS7)に、kickstartファイルがCentOS6と若干違うため、
OSインストールできず、フリーズしたりするのでメモしときます。
CentOS8とか出たらまた考えないといけないパターン（汗）
■kvm-cent7.cfg
環境によって違うと思いますが、毎回変更する部分は固定IPアドレスとホスト名くらいです。
%endを入れないとOSインストール時にフリーズします。bootdriveはvdaに。
それ以下はユーザー作成とか自動化してます。

■kvm-cent7.txt
あとは上記のkickstartファイルをkvmコマンドで当てればOKです。
Cent6と変わらないはず。

■まとめ
最近dockerばかり触っているので、KVMのサーバ管理のめんどくささに唖然とした….
