Xen ne créer pas mon domU

Support Debian
#1

Bonjour,

Je découvre Xen mais j’éprouve quelque difficulté… Je n’arrive pas a démarrer la machine que j’ai créer… Voila ce que j’ai fais (si vous voulez les détails, vous n’avez qu’a demander) :

  • installation de xen-linux-system-2.6.26-2-xen-686
  • update de grub puis reboot
  • création de mes volumes logique pour ce qui est systèm, data et swap (création groupe de volume “Vgcreate xenDisk /dev/hda3”, “lvcreate --size 6GB --name webSys xenDisk” pour la créatoin des dirsque dur logigue, puis après formatage)
  • monter les disque dur créer dans /mnt
  • installation a l’aide de debootstrap “debootstrap lenny /mnt/webSys ftp.ch.debian.org/debian”
  • configuration des interfaces et fstab de ma nouvelle machine (dans /mnt/webSys/etc/network/interfaces et fstab)
  • démontage des disque dur logique dans /mnt/

Ensuite, je créer mon fichier de configuration “/etc/xen/xenWeb” et j’ai insérer ca :

[code]kernel=’/boot/vmlinuz-2.6.26-2-xen-686’
memory = '368’
maxmem = '768’
name = 'srv-xen-web’
vcpus=1
vif = [ ‘ip=192.168.1.251’ ]
netmask = '255.255.255.0’
gateway = ‘192.168.1.250’

disk = [ ‘phy:/dev/xenDisk/webSys,hda1,w’, ‘phy:/dev/xenDisk/webData,hda2,w’, ‘phy:/dev/xenDisk/webSwap,hda3,w’ ]

hostname=‘srv-xen-web’

root = ‘/dev/xenDisk/webSys’
[/code]

Ensuite, je créer ma machine virtuel avec “xm create /etc/xen/xenWeb”… Mais lorsque je fais “xm list”, j’ai que mon domain0…

Dans mes fichier de logs, j’ai cela quand j’execute “xm create /etc/xen/xenWeb” :
