Manifeste d'importation de VM
Le manifeste d'importation est un fichier XML créé et consommé par les opérations ImportInstancede l'API Amazon EC2 et. ImportVolume Notez que ces opérations ne sont pas prises en charge par le AWS CLI.
Le manifeste permet de diviser une image de machine virtuelle en petites parties pour le transfert, puis de la réassembler à destination, avec possibilité de réessayer des transferts partiels ayant échoué. Ce fichier est généralement créé, consommé et détruit par les outils Amazon EC2 sans intervention de l'utilisateur.
Dans certaines situations exceptionnelles, les développeurs peuvent souhaiter créer un manifeste manuellement ou par programmation, ce qui permet de contourner certaines opérations d'API tout en fournissant un manifeste pour d'autres opérations nécessitant le fichier comme valeur de paramètre.
Cette rubrique décrit la structure du manifeste et fournit un exemple de fichier.
Note
La manipulation directe du manifeste s'écarte du flux de travail standard de l'API Amazon EC2. Nous vous recommandons plutôt de suivre les procédures décrites dans les Import/Export processus de machine virtuelle.

Exemples
Ce premier exemple de manifeste décrit une image de volume en deux parties. Les fichiers contenant les pièces se trouvent sur un système local et doivent être chargés sur Amazon S3.
