Alain, Basically, it allows a customer to connect up to 4 z/VM systems (even on 4 separate CECs, i.e. separate z10's) into more of a single system, but not exactly. Many userids can be moved from one system to another, without taking them down to move them. The z/VM systems will not need to be at the same z/VM maintenance level (but at least at some future version/maintenance level to get the support). The new CP code to let this happen will most certainly require a substantial design effort for the IBM z/VM Development Lab. It appears to be all aimed at hosting highly availability servers.
I don't want to try to translate IBM's words into even English. You'd probably be best served by googling: IBM z/VM Single System Image The IBM web sites displayed should provide overviews, and as much information as IBM currently has made public.
