Installation de l'appliance Engine

Nous installons l'engine sur le noeud 01. Il y deux méthodes pour l'installation :

• via le cockpit dashboard du noeud
• depuis la console en ligne de commande

Nous nous connectons à l'interface Web du cockpit du node :

https://ovirt01.lab.grohub.pro:9090

Dans le menu à gauche, cliquez sur “Virtualization” et “Hosted Engine”. Appuyez sur le bouton “start” du choix “Hosted Engine”. Renseignez les informations concernant la VM à créer (configuration VM, réseau, utilisateurs…), et passez à la fenêtre suivante avec le bouton “Next”.

À poursuivre

Nous nous connectons en SSH sur le noeud sur lequel nous allons installer l'engine
Nous lançons le playbook

# hosted-engine --deploy

Une série de question va nous être posée.

[ INFO  ] Stage: Initializing

          During customization use CTRL-D to abort.
          Continuing will configure this host for serving as hypervisor and will create a local VM with a running engine.
          The locally running engine will be used to configure a new storage domain and create a VM there.
          At the end the disk of the local VM will be moved to the shared storage.

L'installation commence. Au bout d'un d'une dizaine de minutes, nous arrivons à la configuration du stockage partagé. Nous utiliserons NFS.

Au moment d'installer l'appliance par elle-même, il nous est demandé de confirmer la taille souhaitée pour celle-ci

Si tout s'est bien passé, le déploiement se termine sans erreur, et vous devriez avoir ce message
