installation xen sous debian lenny
Bonjour,
J'ai voulu essayer d'installer xen sur ma debian lenny, qui a un noyau
2.6.21, mais j'ai des erreurs quand j'essaie de le lancer...
Déja, au niveau de l'install des paquets, j'ai remarqué, qu'il n'y avait
pas de linux-image 2.6.21 por xe, mais j'avais lu qu'apparemment, ce
n'est plus la peine à partir du 2.6.21.
Voila les paquets installés:
# aptitude install xen-utils-3.1-1 xen-docs-3.1 xen-hypervisor
.....
Les NOUVEAUX paquets suivants vont être automatiquement installés :
iproute libatm1 libc6-xen xen-hypervisor-3.1-1-i386 xen-utils-common
....
Les NOUVEAUX paquets suivants vont être installés :
iproute libatm1 libc6-xen xen-docs-3.1 xen-hypervisor-3.1-1-i386
xen-utils-3.1-1 xen-utils-common
J'ai crée un fichier image /home/thierry/xen_debian_etch.iso sur
laquelle j'ai mis une debian etch par debootstrap.
J'ai lancé le script pour la configuration du réseau en bridge:
/etc/xen/scripts/network-bridge start
Ce qui me donne ceci, en nouvelle interface:
xenbr0 Lien encap:Ethernet HWaddr 00:0E:7B:AC:A6:97
inet adr:192.168.0.12 Bcast:192.168.0.255 Masque:255.255.255.0

la configuration de la machine virtuelle /etc/xen/debian_etch donne cela:
kernel = "/boot/vmlinuz-2.6.21.0710041819"
memory = 128
name = "debian_etch"
root = "/dev/hda1 ro"
ramdisk = '/boot/initrd.img-2.6.21.0710041819'
disk = [
'file:/home/thierry/xen_debian_etch.iso,hda1,w','phy:/dev/hda6,hda2,w']
vif = [ '' ]
dhcp="dhcp"
Mais quand je tape: xm create -c /etc/xen/debian_etch
Cela me donne:
WARING! Can't find hypervisor information in sysfs!

Et quand j'essaie de lancer xend, ca me donne ca:

Ext-ce que ca vient du noyau 2.6.21?
Je l'ai recompilé recemment à partir des sources mais en pfrenant la
config du linux-image 2.6.21.
Si quelqu'un a une idée? :-)
Merci :-)
