The memory deduplication mechanism has been used in virtualized environment. The Linux kernel, however, was implemented as anonymous pages with the same content across inter-virtual machines. To resolve this problem, previous work was considered in the page cache inside the guest. So, we propose a KVM-based deduplication mechanism which is used on the host page cache. It does not require a modification of the guest kernel. Our implementation detects more sharing opportunities than the KSM (by factor of 2x), and its CPU overhead is less than 4%. Also, it reduces the page swap in/out by 40% compared to default VMs in the worst case. Thus, the page cache deduplication is required in virtual environments.
