■vmplayer上のsqueezeにopenvzを導入。
Wheezy上で2.6.32-042stab059.7カーネルはちょっと古すぎ。。。
ちなみにx86系よりamd64系の方がハードルが上がります。
$ echo "wheezy" > /dev/null;uname -r
3.2.0-4-amd64
$ echo "squeeze" > /dev/null;uname -r
2.6.32-5-amd64
$ grep flags /proc/cpuinfo | sed s/" "/"\n"/g | grep vmx

■OpenVZの導入
$ OPT=$(echo `uname -r` | sed s/"-amd64"/"-openvz&"/); \
sudo apt-get install -y linux-image-$OPT linux-headers-$OPT linux-headers-2.6.32-5-common-openvz
$ sudo apt-get install -y vzctl vzdump vzquota
$ sudo apt-get install -y debootstrap
$ sudo apt-get install -y libvirt-bin uuid-runtime
■grubの確認
OpenVZカーネルで起動するようになっているので、
そのまま再起動
$ grep "menuentry" /boot/grub/grub.cfg | nl -w2 -v0 | sed s/"--"/"\n\t&"/g

■OpenVZのサービス起動を確認
