Abstract
A method for securely modifying metadata of a secure guest instance that is personalized by an initialization code, using firmware that maintains metadata of the secure guest is disclosed. The method comprises starting a secure guest instance using a hypervisor, receiving, by the secure guest instance, user-specific data, and personalizing, by the secure guest instance, the secure guest instance using the user-specific data. The method comprises also receiving, by the secure guest instance, a request structure for modifying the metadata of the secure guest instance, verifying partially, by the secure guest instance, the request structure using the user-specific data and upon successful verification passing the request structure to the trusted firmware for modifying the metadata of the secure guest instance, and verifying, by the trusted firmware, the request structure and upon success modifying the metadata, as specified by the request structure.
