Research for fault isolation of memory protection in virtual machines
Zhang Huan-sheng · Jisuanji gongcheng yu sheji · 2008
A research of memory protection technology and how to implement are discussed.One way to provide fault isolation among cooperating software modules is to place each in its own address space.However,for tightly-coupled modules,this method would be lead to context switch overhead.To solve this problem in VM,a technology is introduled,which present a software approach to imple-menting fault isolation within a single address space.It is to be checked that this method is efficient software-based fault isolation,and this technology have been successfully used in an actual virtual machines.
