VPSやレンタルサーバを借りてると、Parallels Virtuozzo（OpenVZの有料版）が使われてる機会が多いので
centos6.2にサーバ仮想化ソフトOpenVZをインストールして試してみました。

centos6.2にサーバ仮想化ソフトOpenVZをインストールして試してみました。

まずはopenvzのレポジトリ（openvz.repo）を追加します。

[root@centos6.2 admin]# cd /etc/yum.repos.d [root@centos6.2 yum.repos.d]# wget http://download.openvz.org/openvz.repo –2012-01-18 21:41:28– http://download.openvz.org/openvz.repo download.openvz.org をDNSに問いあわせています… 64.131.90.11 download.openvz.org|64.131.90.11|:80 に接続しています… 接続しました。 HTTP による接続要求を送信しました、応答を待っています… 200 OK 長さ: 2205 (2.2K) [text/plain] `openvz.repo’ に保存中 100%[======================================================================================================================================================>] 2,205 –.-K/s 時間 0s 2012-01-18 21:41:28 (376 MB/s) – `openvz.repo’ へ保存完了 [2205/2205] [root@centos6.2 yum.repos.d]# rpm –import http://download.openvz.org/RPM-GPG-Key-OpenVZ

次にOpenVZ用のカーネルなどを（openvz.repo）からインストール。

[root@centos6.2 yum.repos.d]#

これでOpenVZ対応のカーネルがインストールされているはずなのでgrub.confを見てみる。

ちゃんと(2.6.32-042stab044.11)になってる、が1/18日に最新版がでていた（2.6.32-042stab044.17）、一応アップデート
