Large (1MB) page support, among several others. <idle speculation> I guess (and I have no IBM-internal knowledge whatsoever about this) that this is all about a three-way battle between Poughkeepsie, Endicott, and Boeblingen. Pok has never been wild about running z/OS under VM, and Boeblingen has shifted from VM as the hypervisor they absolutely needed to make Linux practical, to KVM, and so perceives that they can do it all on their own. Where does this leave z/VM? In third place with insufficient resources, I suspect. Maybe little has changed since the 1970s and 80s that Lynn Wheeler writes of here so often... </idle speculation> Tony H. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
