Linux-VServerのゲストOSとしてCentOSをインストール（続き）

Linux-VServerのゲストOSとしてCentOSをインストールの続き

ゲストOSのインストールが遅いのはyumのダウンロードのミラーが遅いことに気づき、/usr/lib/util-vserver/distributions/centos5/yum.repo.d/CentOS-Base.repoを書き換えたら、よくなった。

しかし、次の問題が発生。

# vserver vserver1 build -m yum --context 42 --hostname vserver1.local \
--interface eth0:192.168.1.11/24 -- -d centos5
You are using a version of yum which is insecure and broken in chroot
related operations; either apply the patches shipped in the 'contrib/'
directory of util-vserver, or ask the author of yum to apply them
(preferred).

In the meantime, 'vyum' will continue with dirty hacks which might not
work when the vserver is running and local DOS attacks are possible.

Execution will continue in 5 seconds...

testingのyumを入れたのは失敗でしたよ。というわけでstableのに戻します（もっといいやり方があるかもしれないけどとりあえずこれで）。

# aptitude uninstall yum
# aptitude install yum

vyumがyumについてエラーを言うのはYum-patch - Linux-VServerで対応するようだ。これは後日やってみよう。

とりあえず今度こそvserverのbuildはエラーなく終わりました。

Building Guest Systems - Linux-VServerに従って動作確認。

おー、動きましたよ。

停止と状態確認はこれで。

root@debian:~# vserver vserver1 stop
Shutting down kernel logger:                               [FAILED]

Vserver 'vserver1' is stopped

上のFAILEDのときにコンソールでは以下のようなメッセージが表示されてた。

vxW: [xid #0] !!! limit: de75704c[VM,9] = 75 on exit.
vxW: [xid #0] !!! limit: dd34b04c[VM,9] = 76 on exit.
vxW: [xid #0] !!! limit: dd3a904c[VM,9] = 153 on exit.
vxW: [xid #0] !!! limit: dd11704c[VM,9] = 29 on exit.

これもおいおい調べよう。
