Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for allowing execution of a system management mode (SMM) code during secure operations in a microprocessor system. SOLUTION: In one embodiment, a system management interruption (SMI) may be first directed to a handler in a secured virtual machine monitor (SVMM). The SMI may then be re-directed to an SMM code located in a virtual machine (VM) that is under the security control of the SVMM. This redirection can be accomplished by allowing reading from and writing to the system management (SM) base register in the processor. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: Techniques for handling certain virtualization events occurring within a virtual machine environment. More particularly, at least one embodiment of the invention pertains to handling events related to the sub-operating system mode using a dedicated virtual machine monitor (VMM) called the system management mode VMM (SVMM), which exists in a separate portion of memory from a main virtual machine monitor (MVMM) used to handle virtualization events other than those related to the sub-operating system mode. In at least one embodiment, a technique for initializing and managing transitions to and from the SVMM is disclosed.
