Peux-tu nous fournir le contenu de /proc/cupinfo (recherche dedans de vmx ou svm de souvenir) ou avec un lscpu ?
Autre point il me semble que Qemu/KVM soit à stopper lorsque l’on veux utiliser Virtualbox essai de vérifier avec un :
# systemctl stop libvirtd
Sinon tente le déploiement d’un système 32 bits.
lscpu donne :

Alors, que peut-on tirer comme conclusions ??
Je peux y arriver ou pas ?
amd athlon 64 3200+ trop vieux
Oui
Via Virtualbox mais sans accélération, après je ne suis pas un utilisateur de Virtualbox donc mise à part ce que je t’avais dit précédemment je ne sais pas.
OK.
Merci de t’être penché sur la question.
Désolé pour ma réponse tardive, mais il se trouve que c’est un hasard.
De ton tout premier message @jsc63 :
https://www.virtualbox.org/manual/ch08.html#vboxmanage-cmd-overview
Usage (VirtualBox non ouvert) :
VBoxManage [<general option>] <command>
* Suggestion (avec l’utilisateur qui lance habituellement VirtualBox) :
VBoxManage modifyvm "Windows 7" --paravirtprovider none
* Espoir ?
Que cela chasse l’info « Accélération : Paravirtualisation Hyper-V » de « System » !
* Autres considérations / implications ?
Lenteurs !
Et à voir sur le tas 
https://www.virtualbox.org/manual/ch08.html#vboxmanage-modifyvm
--paravirtprovider none|default|legacy|minimal|hyperv|kvm:Specifies which paravirtualization interface to provide to the guest operating system.
Specifyingnoneexplicitly turns off exposing any paravirtualization interface.
The optiondefaultselects an appropriate interface when starting the VM, depending on the guest OS type.
This is the default option chosen when creating new VMs.
Thelegacyoption is used for VMs which were created with older Oracle VM VirtualBox versions and will pick a paravirtualization interface when starting the VM with Oracle VM VirtualBox 5.0 and newer. Theminimalprovider is mandatory for Mac OS X guests.
kvmandhypervare recommended for Linux and Windows guests respectively.
These options are explained in Section 10.5, “Paravirtualization Providers”.

Peut-être qu tu pourrais me dire si oui ou non il est capable de virtualiser ?? (je suis sur que oui mais on ne sais jamais).

Bonjour,

Bonjour,
Merci pour ta proposition, mais comment ça marche ?
Désolé pour l’ignorance…

jsc63
Je fais l’hypothèse que ton CPU ne propose pas la virtualisation matérielle (cela semble bien être le cas)
est-ce la version 6.1 de virtualbox que tu utilises ?
sous quel debian travailles-tu ?
J’utilise Debian 10 et la dernière version de Virtualbox.
Effectivement, mon CPU ne propose pas la virtualisation matérielle.
c’est bien virtualbox 6.1 qui est en place sur ton système ?
que donne :
apt-cache policy virtualbox
?
donne :
virtualbox:
Installé : (aucun)
Candidat : (aucun)
Table de version :
`
Le deb installe la version 6.1.4.
Mais comment avez-vous installé le paquet virtualbox ?
je suis étonné qu’il n’y ait rien avec “apt-cache policy virtualbox” … (ça me parait pas normal)
quel est le contenu de /etc/apt/sources.list ?
Coucou !
Désolé pour le long silence et le vent que j’ai mis à @invar.
Mais à force de creuser, j’ai trouvé la solution : Virtualbox 5.2.
En effet, cette version supportant le x32, elle virtualise même sans AMD-V. Donc, ça fonctionne !
Merci à tous pour vos réponses ! Vous êtes une super communauté.
