System and how to manage the state machine in a virtual machine operating

摘要

PROBLEM TO BE SOLVED: To perform better management and control of VM (virtual machine) operations.;SOLUTION: Methods and systems are provided to control transitions between a virtual machine (VM) and a Virtual Machine Monitor (VMM). A processor uses state action indicators to load and/or store associated elements of a machine state before completing the transition. The state action indicators may be stored in a Virtual Machine Control Structure (VMCS), predetermined, and/or calculated dynamically. In some embodiments, the values loaded can be directly acquired from the VMCS, predetermined and/or calculated dynamically. In some embodiments, the values stored may be acquired directly from the machine state, predetermined and/or calculated dynamically.;COPYRIGHT: (C)2009,JPO&INPIT
