Sharing memory pages having regular expressions within a virtual machine

摘要: A lightweight technique for sharing memory pages within a virtual machine (VM) is provided. This can be used on its own to implement intra-VM page or it augmented with across VMs. Memory whose content described by some succinct grammar, such as regular expression simple pattern, are identified VM. If the of matches proposed share page, but only in scope VM which belongs, i.e., sharing. All other pages, those that not patterns, candidates all currently active VMs, inter-VM Either fully functional VMs and/or context each implemented.
