Exécution du script
Les messages suivants proviennent d'une exécution du script :
PowerCLI C:\scripts> .\CloneVMs.ps1
Your vCenter address: 10.117.44.17
Your vCenter admin user name: administrator
Your vCenter admin user password: *******
Clone Type<"Full"> : Full
Disable vSphere VM Console ("yes" or "no", recommend "yes") : yes
La durée du processus de clonage dépend du nombre de machines de poste de travail et peut aller de plusieurs minutes à plusieurs heures. Pour vérifier que le processus est terminé, dans vSphere Client, assurez-vous que la dernière machine virtuelle de poste de travail est mise sous tension, qu'elle dispose de son propre nom d'hôte unique et que VMware Tools est exécuté.
