Guang Shi · Jisuanji gongcheng yu sheji · 2010
To reduce the overhead of memory virtualization in virtual machine monitor and improve the performance of memory virtua-lization,two mechanism of memory virtualization are analyzed,the mechanism of memory virtualization based on Intel EPT(extended page table) is researched,the privileged and defect of two proposals based on EPT are analyzed,the factors affecting the performance of memory virtualization are further analyzed.To solve the page fault of EPT,the page pool of dynamic memory allocation scheme is proposed.The implementation shows that memory virtualization based on EPT can simplify the design and improve the performance of memory virtualization effectively.
