Depuis un DVD d'installation:

• installation minimale
• paquet openssh-server

Modification du fichier <path>/etc/apt/sources.list</path> (ou copie depuis virt2 ou virt3)

• On met le système à jour

  aptitude update && aptitude upgrade
  

• On installe les logiciels indispensables

  aptitude install vim ntp
  

Network Manager
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="dom0_mem=1024M dom0_max_vcpus=1 dom0_vcpus_pin" 
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)

cd /etc/grub.d/
ln -s 20_linux_xen 09_linux_xen
update-grub
