Abstract

A data processing system isolates a virtual trusted platform module (vTPM) manager in the processing system from other management software in the processing system. In one example process, the processing system launches a virtual machine monitor (VMM) that includes a memory-mapped input/output (MMIO) trap. The processing system also launches a vTPM manager in a first virtual machine (VM). In addition, the processing system launches a second VM to contain virtual machine management programs other than the vTPM manager and the MMIO trap. Other embodiments are described and claimed.
