手順

$ cd /path/to/work

# テンプレートの確認
$ veewee vbox templates | grep -i centos

# 設定ファイルを作成
$ veewee vbox define cent7 'CentOS-7.0-1406-x86_64-netinstall' --workdir=/path/to/work

# 設定ファイルの修正
$ emacs definitions/cent7/definition.rb
$ emacs definitions/cent7/ks.cfg


# veewee vbox build cent7

設定ファイル

definition.rb

(略)
  :iso_src => "http://mirror.nsc.liu.se/centos-store/7.0.1406/isos/x86_64/CentOS-7.0-1406-x86_64-NetInstall.iso",
(略)
  :postinstall_files => [
    "base.sh",
#    "chef.sh",
#    "puppet.sh",
    "vagrant.sh",
    "virtualbox.sh",
    #"vmfusion.sh",
    "cleanup.sh",
    "zerodisk.sh"
  ],

ks.cfg

(略)
url --url=http://mirror.nsc.liu.se/centos-store/7.0.1406/os/x86_64/
(略)

メモ

definition.rbのiso_src, ki.cfgのurlは、初期値のURLが404になっているので、修正する必要がある
postinstall_files は、vagrant+virtualbox用の環境が欲しいので、chef, puppet はコメントアウト
デフォルトで用意されるpuppet.sh は、有効にしていると以下のようなエラーが発生する

 One of the configured repositories failed (epel),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Disable the repository, so yum won't use it by default. Yum will then
        just ignore the repository until you permanently enable it again or use
        --enablerepo for temporary usage:

            yum-config-manager --disable epel

     4. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=epel.skip_if_unavailable=true
