Abstract

La présente invention concerne un procédé de mise à niveau de machine physique, un procédé de migration de service et un appareil. Le procédé de mise à niveau de machine physique consiste : à recevoir une requête de mise à niveau envoyée par une gestion d'infrastructure virtualisée (VIM), la requête de mise à niveau étant utilisée pour demander de mettre à niveau une première machine physique, et une ou plusieurs premières machines virtuelles résidant sur la première machine physique ; à réaliser le traitement de migration de services s'exécutant sur lesdites premières machines virtuelles vers une ou plusieurs deuxièmes machines virtuelles selon la requête de mise à niveau ; à envoyer un message de migration à la VIM pour faire migrer lesdites premières machines virtuelles vers une ou plusieurs troisièmes machines virtuelles après que le traitement est achevé ; à recevoir un résultat de migration renvoyé par la VIM ; et à notifier à la VIM d'exécuter le traitement de mise à niveau de la première machine physique selon le résultat de migration. La présente invention résout le problème d'interruption d'exécution de services durant la mise à niveau d'une VIM dans l'état de la technique associé, permettant ainsi d'atteindre l'effet de mise en œuvre de la mise à niveau de VIM, tout en garantissant que des services ne sont pas ininterrompus.
