[Résolu] [XEN] installer Xen avec 4GO de RAM

Support Debian
#1

Salut;

J’ai un tout nouveau serveur Dell qui va faire office de serveur hôte pour un système XEN

ce serveur ayant 4Go de RAM et j’ai donc mis une distrib 64Bits pensant que le support serait "natif"
Mais avec le kernel que j’ai installé (le dernier xen dispo en apt-get --> 2.6.18-6-xen-amd64) quand je fais un top, je n’ai que 3 GO…

Faut il que je recompile le kernel? ou y a t’il qu’un ptit truc de rien du tout à modifier pour que tout soit OK…

Merci.

[EDIT]
xen:~# uname -a
Linux xen 2.6.18-6-xen-amd64 #1 SMP Fri Dec 12 07:02:03 UTC 2008 x86_64 GNU/Linux

pour infos! :wink:

#2

Y a-t-il déjà des machines virtuelles sur ce serveur ?
Dans ce cas, lorsqu’elles sont en route, elles prennent de la mémoire à l’hôte. Tu dois pouvoir voir cela avec la commande# xm list

Sinon, qu’en est-il avec le noyau normal ?

#3

Salut et merci pour ta réponse.

j’ai passé la commande xm list, je ne vois que mon Dom0 avec 3Go de mem…
xen:~# xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 2981 4 r----- 20.9

En revanche sur un kernel plus récent (le 2.6.24-etchnhalf.1-amd64) là dans mon top j’ai bien 4Go de RAM…

Donc je crois bien que je vais devoir recompiler…non??

#4

Si ça passe avec le noyau de EtchnHalf 2.6.24, pourquoi recompiler ???

#5

toutes mes excuses pour la mauvaises section, j’avais 2 onglets ouverts sur le forum, j’ai du inverser… :blush:

Sinon, j’ai mis ce kernel parcequ’il était précompilé pour Xen…sur le coup ca m’a semblé plus simple…

Je vais voir pour l’installer sur le 2.6.24

Je peux bouger mon sujet? ou je dois faire la demande à un modo?

#6

J’ai l’impression que le noyau etchnhalf n’existe pas en xen: packages.debian.org/search?suite … nux-system
Je ne sais pas si c’est si simple de compiler un noyau pour xen…
Sinon, il y a un 2.6.26 en backport mais tu pourrais aussi passer en lenny

#7

Ce qui me génait à passer en lenny c’est que c’est encore marqué en testing… ça correspond à une beta? ou c’est plus évolué que ça?

Je suis nouveau sur debian, donc je ne connais pas trop les impacts que ça a.

D’après toi pour un serveur de prod c’est jouable?

Merci.

#8

En ce moment, lenny est en phase de “deep freeze” (c’est à dire que seules les corrections de bugs critiques sont acceptées, les autres seront remises à plus tard). Son passage en stable est donc imminent (on parle du 14 février: lists.debian.org/debian-devel-an … 00000.html).
Du coup, ce n’est probablement pas très risqué de passer en lenny maintenant…
Tu peux aussi tester avec le noyau xen du backport ou simplement avec celui de lenny en adaptant ton sources.list si tu es frileux :wink:

#9

[déplacé]

#10

En tout premier, merci à fran.b pour la réactivité!

Bon je suis passé sur lenny, mais j’ai maintenant un autre problème qui est pur Xen…
Donc pour l’install pas de soucis, je suis passé en 2.6.26-1-xen-amd64 j’ai bien le support de mes 4 Go de RAM, tout est OK

Je passe donc à la création de mes VM.
Je fais la même méthode quand j’étais sous etch et le problème, c’est que mes machines ne boot pas…

Je prends la main en faisant xm console vm1 et je reste bloqué sur

Starting periodic command scheduler: crond.

et quand je lance putty, j’ai

Server refused to allocate pty
stdin: is not a tty

En gros j’ai une grosse impression que la distrib ne c’est pas installée correctement…

Je précise que je fais une install via debootstrap que j’install une lenny kernel 2.6.26-1-xen-amd64

Quelqu’un connait t’il??

Autre question est il possible de choisir etch comme distrib en mettant le kernel 2.6.26-1-xen-amd64?

Par avance merci.

#11

peux-tu préciser comment tu as installé la machine virtuelle ?
si c’est avec xen-tools (xen-create-image…): as-tu eu des messages d’erreur lors de la création ?
tu as installé en lvm ou en loop ?

#12

pardon, j’ai oublié de préciser ca…

L’install se fait avec xen-tool, sur un volume lvm:

la commande que je passe:

xen:~# xen-create-image --hostname=vm1 --size=5Gb --swap=128Mb --ip=192.168.1.100 --force --memory=128Mb --debootstrap

aucune erreur à la création, et quand je fais un lvdisplay, j’ai

 --- Logical volume ---

  VG Name                xen

  Allocation             inherit

tout semble normal non?

#13

À vrai dire (et à regret), je ne connais pas bien lvm.
Les seules machines virtuelles que j’ai créée avec Xen sont en loop…
Il y a un tuto dans T&A : viewtopic.php?f=8&t=13190 c’est pour etch mais pour lenny c’est plus simple pour le réseau en particulier. Il faut les paquets bridge-utils et uml-utilities et dans /etc/xen/xend-config.sxp, mettre (network-script network-bridge) puis redémarrer le démon.
Tu as fait ça ?

Sinon, il n’y a rien de particulier dans le log de création: /var/log/xen-tools/vm.log ?

#14

arf!

si j’ai un truc de bizarre que je viens de remarquer…mais je sais pas si c’est utile:
Unknown option: debootstrap

mais juste après j’ai installation method: debootstrap: done…

ci joint ce que j’ai à l’écran lors de la création de ma machine:

as-tu édité le fichier /etc/xen-tools/xen-tools.conf ? colle le ici, pour voir
tu dois avoir une option : install-method = debootstrap
bien sûr, il faut que debootstrap soit installé sur la machine hôte, c’est le cas ?

#16

normalement, tu dois voir tout ce que fait debootstrap:[code]Installation method: debootstrap

J’ai bien modifié le xen-tools.conf.
je te le post demain matin…ma machine n’est pas accéssible ici…

Concernant debootstrap, je vois tout ce qu’il fait dans les logs de la VM j’ai aucunes erreurs non plus…

Je te posterai le contenu aussi demain si tu veux.

En gros je suis désespéré… :cry:

Merci pour ton aide en tout cas.

#18

bon j’y ai cru mais c’est toujours pas ça…

voilà mon xen-tools.conf:

#  If you're using the lenny or later version of the Xen guest kernel you will

#  You may specify the things to use here:
#
 serial_device = hvc0 #default
 serial_device = tty1
#
# disk_device = xvda #default
# disk_device = sda

Je n’avais pas vu au départ les options de fin: "If you’re using the lenny or later version of the Xen…"
j’ai donc décommenté les lignes, mais c’est aps mieux…

au passage pour que ca soit vraiment illisible, je mets un log de création de machine, au cas ou qq’un voit une erreur que j’ai raté!:

#19

Je vais essayé d’apporter un peu d’eau à mon moulin…

concernant mon problème putty, “Server refused to allocate pty”:

[quote]The problem is lack of mountpoint defined in fstab. Just add this line to /etc/fstab:
none /dev/pts devpts gid=5,mode=620 0 0
[/quote]

sauf que je ne peux même pas me connecter directement sur la VM à partir de la machine hôte…
Le problème vient de debootstrap? vient du fait que j’installe une etch avec le kernel 2.6.26? j’ai le même problème en mettant lenny comme distrib…

Toujours personne avec une idée??

#20

autre chose, quand je lance ma console xen:
xm create -c /etc/xen/vm41.cfg, j’ai:
