Hi All.
I have faced the above issue and opened the tac case after that it was listed as bug,
got the bellow errors:
failed in Task: 'Reconfigure controller VM to add extra config params' with Error: '(vim.fault.TaskInProgress) { dynamicType = , dynamicProperty = (vmodl.DynamicProperty) [], msg = 'Another task is already in progress.', faultCause = , faultMessage = (vmodl.LocalizableMessage) [], task = 'vim.Task:haTask-1-vim.VirtualMachine.powerOn' }'
Also Retried the same various times but did not succeeded,
i have now planned to use other available versions.
