    • 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.
    • 提供了一种执行包括基于硬件的TPM的信息处理系统的起始序列的系统,方法和程序产品。 多个PCR存储在TPM中,并且当开始序列开始时被初始化为预定状态。 在执行启动序列期间,软件模块(包括管理程序)将加载系统的内存。 计算由加载软件模块产生的PCR值。 将所得PCR值与预期的PCR值进行比较。 如果PCR值与预期PCR值匹配,则在管理程序下创建虚拟环境。 虚拟环境包括虚拟机和虚拟信托平台模块(vTPM),虚拟机用于满足虚拟机TPM请求。
