■KVMに必要なCPUフラグが無いので、通常のQEMUを導入する。
$ grep flags /proc/cpuinfo | sed s/" "/"\n"/g | grep "vmx\|svm"
■qemu-launcherの導入
$ apt-cache search ^qemu | grep "GUI\|フロントエンド"
aqemu - QEMU および KVM の Qt4 フロントエンド
qemuctl - qemu 制御用 GUI
qemu-launcher - QEMU コンピュータエミュレータ向け GTK+ 版フロントエンド
qtemu - QEMU 用 GUI
$ sudo apt-get install -y qemu-launcher
■vyattaは以下を選択。
$ ~/iso_system/vyatta/vyatta-livecd_VC6.5R1_i386.iso
■数年前に使った時とあまり変わらず遅い(同じマシンのWindows上のvmplayerよりはるかに遅い)のと、
GUIのマウス操作が無応答になるので却下。。。
見た目はvmplayerやvirtualboxと同様なので、コマンドを忘れていても使える。
$ sudo pkill qemu*
■LXCの導入
※0.7.2ではcgroupのメモリ管理が出来ない。
0.7.3以上が推奨。
Setting up LXC on Debian squeeze
http://sutas.eu/setting-up-lxc-on-debian-squeeze/
$ sudo apt-get install bridge-utils debootstrap
$ sudo apt-get install -y lxc
■LXCの初期設定
$ echo "cgroup /sys/fs/cgroup cgroup defaults 0 0" | sudo tee -a /etc/fstab
cgroup /sys/fs/cgroup cgroup defaults 0 0
$ sudo mount cgroup
$ lxc-version
lxc version: 0.7.2
$ sudo lxc-checkconfig | grep missing
Cgroup memory controller: missing
■lennyでは無くsqueezeを導入しようとするが「Couldn't find these debs: dhcp-client」でコケる。
$ grep -i lenny /usr/lib/lxc/templates/lxc-debian
lenny $cache/partial-$arch http://ftp.debian.org/debian
$ sudo cp /usr/lib/lxc/templates/lxc-debian /usr/lib/lxc/templates/lxc-debian.org
$ sudo sed -i s/lenny/squeeze/ /usr/lib/lxc/templates/lxc-debian
$ sudo grep squeeze /usr/lib/lxc/templates/lxc-debian
squeeze $cache/partial-$arch http://ftp.debian.org/debian
$ sudo mkdir -p /lxc/vm0
$ sudo /usr/lib/lxc/templates/lxc-debian -p /lxc/vm0/ 2>&1 | grep ^E
E: Couldn't find these debs: dhcp-client
■パッケージが「isc-dhcp-client」に置き換わっているので対応する。
また、MIRROR参照は直接書き換えてしまう。
$ apt-cache search dhcp-client
dhcpcd - IPv4 ネットワーク自動設定用 DHCP クライアント
isc-dhcp-client - ISC DHCP クライアント
isc-dhcp-client-dbg - ISC DHCP クライアント (デバッグシンボル)
pump - IP 設定の自動化のための BOOTP および DHCP 用クライアント
$ grep "dhcp-client\|ftp" /usr/lib/lxc/templates/lxc-debian
dhcp-client,\
squeeze $cache/partial-$arch http://ftp.debian.org/debian
$ sudo sed -i s/dhcp-client/isc-dhcp-client/ /usr/lib/lxc/templates/lxc-debian
$ sudo sed -i s/ftp.debian.org/ftp.jp.debian.org/ /usr/lib/lxc/templates/lxc-debian
$ grep "dhcp-client\|ftp" /usr/lib/lxc/templates/lxc-debian
isc-dhcp-client,\
squeeze $cache/partial-$arch http://ftp.jp.debian.org/debian
■再度作成するが、今度はperlの警告が出る。
$ sudo /usr/lib/lxc/templates/lxc-debian -p /lxc/vm0/
...
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:

■確かに未設定。

LC_ALL=
$ echo -e "export LANGUAGE=\"ja\"\nexport LC_ALL=\"C\"" | sudo tee -a ~/.bashrc
export LANGUAGE="ja"
export LC_ALL="C"
$ exit
■再々作成。今度はLANG変数ですか。
$ sudo /usr/lib/lxc/templates/lxc-debian -p /lxc/vm0/ | tee -a vm0.log
$ sudo locale | grep "LANGUAGE\|LC_ALL"
LANGUAGE=ja
LC_ALL=C
