Je viens de recevoir mon KS2G OVH et j’aimerais y faire tourner des linux containers (lxc).
\nCependant, j’ai constat\u00e9 que le noyau OVH manquait de pas mal d’options notament sur le r\u00e9seau et les cgroups.
\nPour rem\u00e9dier \u00e0 tout \u00e7a, il va falloir compiler un nouveau noyau et tant qu’\u00e0 faire le dernier en date de notre cher Linus.
\n<\/p>\n

On download le dernier kernel officiel<\/p>\n

wget https:\/\/www.kernel.org\/pub\/linux\/kernel\/v3.x\/linux-3.11.1.tar.xz<\/pre>\n
On r\u00e9cup\u00e8re le dernier fichier de config kernel chez OVH<\/p>\n
wget -c ftp:\/\/ftp.ovh.net\/made-in-ovh\/bzImage\/latest-production\/config-3.10.9-xxxx-grs-ipv6-64<\/pre>\n
On install les d\u00e9pendances pour la compilation<\/p>\n
apt-get install make gcc lzma ncurses-dev dpkg-dev<\/pre>\n
Il faut ensuite bien s\u00fbr extraire la livraison<\/p>\n
tar -xvf linux-3.11.1.tar.xz<\/pre>\n
Copier le fichier de conf OVH pour prise comme base. C’est cette conf \u00e0 laquelle on ajoutera la prise en charge des cgroups et divers param\u00e8tres r\u00e9seau<\/p>\n
cp config-3.10.9-xxxx-grs-ipv6-64 linux-3.11.1\/.config<\/pre>\n
On lance le menu de configuration (dont la conf de base est celle du fichier OVH)<\/p>\n
cd linux-3.11.1\nmake menuconfig<\/pre>\n
L’id\u00e9e c’est d’ajouter la prise en charge des options ci-dessous<\/p>\n
General setup --->\n    [*] Control Group support --->\n        [*] Example debug cgroup subsystem\n        [*] Namespace cgroup subsystem\n        [*] Freezer cgroup subsystem\n        [*] Device controller for cgroups\n        [*] Cpuset support\n        [*] Include legacy \/proc\/\/cpuset file\n        [*] Simple CPU accounting cgroup subsystem\n        [*] Resource counters\n        [*] Memory Resource Controller for Control Groups\n        [*] Memory Resource Controller Swap Extension\n        [*] Memory Resource Controller Swap Extension enabled by default (NEW)\n        [*] Enable perf_event per-cpu per-container group (cgroup) monitoring\n        [*] Group CPU scheduler --->\n        [*] Group scheduling for SCHED_OTHER\n        [*] Group scheduling for SCHED_RR\/FIFO\n        <*> Block IO controller\n        [*] Enable Block IO controller debugging\n    -*- Namespaces support --->\n        [*] UTS namespace\n        [*] IPC namespace\n        [*] PID Namespaces\n        [*] Network namespace<\/code>\n\n    [*] Networking support --->\n        Networking options --->\n        <*> 802.1d Ethernet Bridging\n        [*] IGMP\/MLD snooping\n        <*> 802.1Q VLAN Support\n        [*] GVRP (GARP VLAN Registration Protocol) support\n\nDevice Drivers --->\n    [*] Network device support --->\n        --- Network device support\n        < > Intermediate Functional Block support (NEW)\n        < > Dummy net driver support (NEW)\n        < > Bonding driver support (NEW)\n        <*> MAC-VLAN support (EXPERIMENTAL)\n        <*> MAC-VLAN based tap driver (EXPERIMENTAL)\n        < > EQL (serial line load balancing) support (NEW)\n        < > Universal TUN\/TAP device driver support (NEW)\n        <*> Virtual ethernet pair device\n        < > General Instruments Surfboard 1000 (NEW)\n\nCharacter devices --->\n    -*- Unix98 PTY support\n    [*] Support multiple instances of devpts<\/pre>\n
On compile notre nouvau noyau et on lui donne un num\u00e9ro de version (pr\u00e9voir plus d’une heure sur un KS2G OVH)<\/p>\n
make KDEB_PKGVERSION=1.0 deb-pkg<\/pre>\n
Enfin on installe notre nouveau noyau<\/p>\n
dpkg -i linux-image-3.11.1-xxxx-grs-ipv6-64_1.0_amd64.deb linux-headers-3.11.1-xxxx-grs-ipv6-64_1.0_amd64.deb<\/pre>\n
Ne pas oublier de positionner le noyau par d\u00e9faut dans \/boot\/grub\/grub.conf sur le nouvau noyau.
\nOn red\u00e9marre et on prie \ud83d\ude09
