In some embodiments, the invention involves a system and method for invoking a series of hypervisors on a platform. A hardware-based secure boot of a chained series of virtual machines throughout the life of the pre-operating system (OS) firmware/BIOS/loader/option ROM execution, with component-wise isolation of the pre-extensible firmware interface (PEI) and driver execution environment (DXE) cores is utilized. In an embodiment, a Cache-As-RAM (CAR) based hypervisor, executing directly from Flash memory manages sequential invocation of a next hypervisor. Other embodiments are described and claimed.
