A method and apparatus for initiating secure operations in a microprocessor system is described. In one embodiment, one initiating logical processor initiates the process by halting the execution of the other logical processors, and then loading initialisation and secure virtual machine monitor software into memory. The initiating processor then loads the initialisation software into secure memory for authentication and execution. The initialisation software then authenticates and registers the secure virtual machine monitor software prior to secure system operations. Executing a secured enter instruction, and preventing access to a secured virtual machine monitor by a non-processor device. |
