Abstract:
A system, method, and program product is provided that executes a start sequence of an information handling system that includes a hardware based TPM. Multiple PCRs are stored in the TPM and are initialized to a predetermined state when the start sequence commences. During execution of the start sequence, software modules, including a hypervisor, are loaded the system's memory. PCR values resulting from the loading of the software modules are calculated. The resulting PCR values are compared with expected PCR values. If the PCR values match the expected PCR values, then a virtual environment is created under the hypervisor. The virtual environment includes a VM and a virtual trust platform module (vTPM) that is used by the virtual machine to satisfy the virtual machines TPM requests.
