  • rare in real world It therefore follows that CoW mechanism must be efficient to be generally applicable We are proposing a paravirtual CoW scheme designed to lower the three major costs of memory sharing detecting duplicate memory pages servicing CoW faults and managing the surplus memory Memory sharing opportunities are commonly detected by comparing content hashes This is indeed the approach used by Waldspurger However the constant growth of the search space as well as increasing performance gap between CPU and memory 5 calls for a better solution We believe that we can detect the majority of duplicate pages at the fraction of the cost by leveraging extra information provided by the guest OSes In particular interception of blk read operations allowed us to find 40 of sharings The additional pieces of information provided by guests are also valuable in servicing CoW faults Our fault handler design is based on a simple observation if CoW fault is the result of a page being deallocated by the guest memory manager there is no need to mem copy since the content of the page is conceptually discarded Finally in order to make the full use of surplus memory from CoW a mechanism

  • in memory execution state of critical services such as drivers as well as OS kernel as well We describe an implementation of VIS Virtualization based Integrity Services on Xen that leverages memory virtualization to allow protection of software components running in a HVM managed by Xen The software components are measured once and protected during their execution lifetime within the guest linear address space The paper will describe the modifications
