Powershell – Restart VM on NUTANIX AHV with call API

Un petit script en Powershell permettant de faire un appel à l’API Nutanix AHV pour gérer l’arret /redémarrage /… des VMs.

Pour l’un de mes clients, j’ai dut gérer le redémarrage et autres actions des VMs planifié depuis un ordonnanceur. Les actions sont réalisés via Powershell qui se connecte à l’API AHV.

Le script peut aussi être téléchargé en cliquant sur le lien ci-dessous :

Attention avec les doubles quotes dans les copier /coller des scriptes, wordpress les interprète. A vous de modifier avec caractère “string” par une vraie double quotes.

La options d’alimentations sur les VM doivent être configurée comme expliqué dans le KB ci-dessous pour pouvoir utiliser les ACPI (Turn off the display = never et Power button action = shutdown) :

Ci-dessous les 2 points importants à configurer au niveau des options d’alimentations sur les serveurs.
