Barge（Docker ホスト用軽量 OS） を試してみる
Qiitaで以下の記事を見つけました。
Barge（Docker ホスト用軽量 OS）って？
http://qiita.com/A-I/items/8dc7ddc52e6038b5c74b
fmfm、たった13MB のDockerホスト用 LinuxOSだって！
これは試してみるしかない！
ISOを作ってみる
以下の手順でisoが作れるっぽいぞ。ってことでやってみました。

■ViertualBoxで試してみる
VirtualBox上の Ubuntu16.04 Desktop で試してみました。
まずは必要そうなソフトを入れておきます。
apt-get update apt-get upgrade -y apt-get install -y git make vagrant virtualbox
おもむろに実行！
root@ubuntu:~/barge# make vagrant vagrant resume barge No usable default provider could be found for your system. Vagrant relies on interactions with 3rd party systems, known as "providers", to provide Vagrant with resources to run development environments. Examples are VirtualBox, VMware, Hyper-V. The easiest solution to this message is to install VirtualBox, which is available for free on all major platforms. If you believe you already have a provider available, make sure it is properly installed and configured. You can see more details about why a particular provider isn't working by forcing usage with `vagrant up --provider=PROVIDER`, which should give you a more specific error message for that particular provider.

あれ？なんか失敗したっぽい。
よくわかんないなぁ。。
Vagrant Boxを使ってみる
以下ページを見ると
Vagrant ですぐに起動できるっぽいので早速やってみました。
https://atlas.hashicorp.com/ailispaw/boxes/barge
■ViertualBoxで試してみる
VirtualBox上の Ubuntu16.04 Desktop で試してみました。
まず前準備
sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get install -y vagrant virtualbox make git
準備完了後
資料どおりにオペレーションしてみます。
$ vagrant box add ailispaw/barge $ vagrant init -m ailispaw/barge $ vagrant up
途中までは問題なく動くのですが
Vagrant up するとフリーズしてしまいます。
ずーっと待つとtimeout。なんかうまくいってないっぽい
調べてみたら以下のページを発見
なんと！VMWareじゃないとだめっぽい！
仮想化ソフトが、ハードウェア仮想化支援機能（Intel VT や AMD-V）を仮想化してホストOS上でも有効にできるのであれば、Nested Virtualization が可能になります。
調べた範囲だと、VMware Player では Nested Virtualization が可能でしたが、VirtualBox では不可能でした。 なので、ホストOS（Windows）上で VMware、ゲストOS（Ubuntu）上で VirtualBox を起動するようにすると、仮想マシン上で Vagrant を使えました。

■VMWareで試してみる
VMWare上の Ubuntu16.04 Desktop で試してみました。
でも VMWareでも同じ場所でタイムアウト。
ちょっと調べてみたところ、IntelVx-T 設定を有効になっていない。
以下のページを参考に 以下のようにIntelVx-T 設定を有効にしてみました。

# vagrant up # vagrant ssh
うごきました！
■ISOも作ってみます(再挑戦)
NFSがインストールされていないとうまくビルドできないようなのでインストール
sudo apt-get -y install nfs-kernel-server

あれ？ うまくいかないなぁ・・・
何かが足りないのかな？
（後で調べる・・・かも）
Docker version を切り替えてみる
