The killer feature of Vserver that none of the others have (and Solaris zones guidelines for bind-mounting /usr read-only try to approximate (poorly)) is the hashification of the files - it can search the guest subtrees for identical files between guests, and comes with a CoW hardlink feature for the supported file systems (ext* at the moment). So both the disk and memory requirements can go down dramatically. I've been wanting such a CoW hardlink breaking feature in ZoL for ages.
