摘要：Virtualization becomes popular in the computer industry because of its benefit like server consolidation, flexibility, utilization of resources and used to reduce the power consumption. By considering these benefits, changes have made in architecture to support virtualization. Implementation of memory management is one of the difficult parts of the virtualization to improve the performance. Nested Page Table is widely used for page walk in the full virtualization systems. Another software technique for page walk in virtualization environment is shadow paging. Shadow paging technique is suffering from overhead to make synchronization between guest page table and hypervisors page table. Nested page table is also suffering from 24 memory accesses to fetch the data from the memory which leads to high memory latency. In this paper, we are re-evaluating the existing techniques and architectural support made for virtualization environment. We propose hashed page table to reduce the memory accesses from 24 to 2. Proposed methodology is divided into three modules. First one is to give the computational time of hash. Hash function must provide unique values for two different virtual addresses which is included in second module. Third module is to calculate benchmark results on the proposed system.
