I have a restricted shell which limits the user from the underlying linux apps and filesystem but authorization is using the usual mechanisms. VIX would allow access to the underlying filesystem bypassing the restricted shell. As for the logs, the user is showing guestUserName=hostd-quiescedsnap but VMAutomation_ReadGuestOperationPolicies fails. hostPolicyString is NULL VixAutomation_IsGuestOperationAllowed fails. No policy for this operation Is this the reason for the failure? What is the required policy and how does this need to be set?
