When I read "Memory Resource Management in VMware ESX server", they use page sharing between domains with hash value of a page. So I wonder that Xen uses this technique or if not, is there anyone who is implementing this to Xen now or willing to do so. There is explicit page sharing in Xen, but the kind of automatic scheme described in that paper. This is largely because it's unclear how great the benefit would be in practice. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
