OpenVZを試す、が、まだうまくいかない

Linux-VServerはバニラカーネルへのパッチとして提供されていて、パッチあたりまくりのCentOSだとうまく当たらないし、そうかといってバニラカーネル＋Linux-VServerにしてしまうとCentOSとは別物になってしまってCentOSの検証環境としては使えないなあと悩んでいて以下のページを見つけました。

• CentOS5.2 にOpenVZを入れてみる | トライアウト ラボラトリ！


• CentOS5.2 にOpenVZを入れてみる(2) | トライアウト ラボラトリ！


• CentOS5.2 にOpenVZを入れてみる(3) | トライアウト ラボラトリ！

そうかOpenVZならCentOSのカーネルにも対応していたのか（もっと早く気付けよ＞私）。ということでトライしてみました。

おおっとなんかエラーが。

で、検索したら本家のドキュメントに行き着く（最初からこちらを見ようね＞私）。

• Install OpenVZ on a x86 64 system Centos-Fedora - OpenVZ Wiki


• Quick installation - OpenVZ Wiki

というわけで続き。

途中で/vz/root/100001/var/lib/yum/というディレクトリが無いっぽいエラー連発。最後にもエラーが。なんか間違えたかな。

調べてみると/vz/root/まではあるがその下はないようだ。/etc/init.d/syslogのほうはあるんだけどな。続きはまた今度。
