di seguito l'errore che si presenta quando provo a creare uno snapshot:

[root@esx2 ~]# vmware-cmd /vmfs/volumes/4e9c2971-7f71fbf4-ff14-b499bab9df8c/GestSQL/GestSQL.vmx createsnapshot "miosnapshot" "" 1 0

Traceback (most recent call last):

  File "/usr/bin/vmware-cmd", line 93, in ?

    main()

  File "/usr/bin/vmware-cmd", line 65, in main

    result = TaskManager().HandleIfTask(result, async=False)

  File "/usr/lib/vmware/vmware-cmd/TaskManager.py", line 17, in HandleIfTask

    else: return self.WaitForTask(task)

  File "/usr/lib/vmware/vmware-cmd/TaskManager.py", line 28, in WaitForTask

    result = task.WaitForCompletion()

  File "/usr/lib/vmware/vmware-cmd/Task.py", line 20, in WaitForCompletion

    onProgressUpdate=self.OnProgressUpdate)

  File "/usr/lib/python2.4/site-packages/pyVim/task.py", line 120, in WaitForTask

   raise task.info.error

1. pyVmomi.VmomiSupport.vim.fault.SnapshotFault: (vim.fault.SnapshotFault) {

   dynamicType = <unset>,

   dynamicProperty = (vmodl.DynamicProperty) [],

   msg = 'A snapshot operation cannot be performed.',

   faultCause = <unset>,

   faultMessage = (vmodl.LocalizableMessage) []

}
