SERVICE PARTITION VIRTUALIZATION SYSTEM AND METHOD HAVING A SECURE PLATFORM

A secure platform system and method for a host computing device. The system includes an ultraboot application that operates in the less privileged user memory and divides the host computing device into a resource management partition, at least one virtual service partition and at least one virtual guest partition. The virtual guest partition provides a virtualization environment for at least one guest operating system. The virtual service partition provides a virtualization environment for the basic operations of the virtualization system. The resource management partition maintains a resource database for use in managing the use of the host processor and the system resources. The virtual service partition is a secure virtualization platform (s-Platform) having at least one isolated secure partition for executing at least one secure application therein. The system also includes at least one monitor that operates in the most privileged system memory. The monitor maintains guest applications in the virtual guest partition within memory space allocated by the virtual service partition to the virtual guest partition. The system also includes a context switch between the monitor and the respective virtual guest partitions and the virtual service partition. The context switch controls multitask processing in the partitions on the at least one host processor.
