| Abstract: | To avoid the performance bottleneck of virtual machine monitor in IO virtualization,problems in current model of IO virtua-lization are analyzed,then a collaborative virtual machine monitor based on IO process machine is proposed.IO virtualization model based on IO process machine is constructed,and processing of IO access request from guest OS is implemented,further,key technologies from device-finding to functional simulation in this model are presented.Implementation principle indicated that IO virtualiz... |
