- On met le système à jour
aptitude update && aptitude upgrade - On installe les logiciels indispensables
aptitude install vim ntp
network-manager doit absolument être désactivé
echo "manual" > /etc/init/network-manager.override
Installation du serveur de virtualisation
Xen
On installe Xen
aptitude install xen-hypervisor-amd64 xen-linux-system-amd64 xen-utils xen-tools bridge-utils xfsprogs
On modifie le fichier de configuration de Xen: <path>/etc/xen/xend-config.sxp</path>
(logfile /var/log/xen/xend.log) (loglevel DEBUG) (xend-http-server yes) (xend-unix-server yes) (xend-tcp-xmlrpc-server yes) (xend-unix-xmlrpc-server yes) (xend-relocation-server yes) (xend-relocation-ssl-server no) (xend-udev-event-server no) (xend-unix-path /var/lib/xend/xend-socket) (xend-tcp-xmlrpc-server-address '0.0.0.0') (xend-tcp-xmlrpc-server-port 8006) (xend-port 8000) (xend-relocation-port 8002) (xend-address '') (xend-relocation-address '') (xend-relocation-hosts-allow '^localhost$ ^.*\\.b2pweb\\.com$') (network-script network-dummy) (vif-script vif-bridge) (dom0-min-mem 1024) (enable-dom0-ballooning no) (total_available_memory 0) (dom0-cpus 1) (vnc-listen '0.0.0.0') (vncpasswd '') (keymap 'fr')
Ajout au fichier <path>/etc/default/grub</path>

GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=1024M dom0_max_vcpus=1 dom0_vcpus_pin"
Pour être sûr que xen soit le premier de la liste (donc celui qui démarre par défaut)
