Techniques for handling certain virtualization events occurring within a virtual machine environment. More particularly and 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 and a technique for initializing and managing transitions to and from the SVMM is disclosed.
