Re: Linux Without Limits: IBM Launch LinuxONE Mainframes
I'm not aware that we've announced a follow on to z12 BC so I would assume so. Jim Elliott follows this newsgroup so will probably want to wade in at some point.

Re: Linux Without Limits: IBM Launch LinuxONE Mainframes
It seems to me this is another abstraction layer that would enable an instance of bare-metal Linux to spool up multiple instances in an LPAR without z/VM. What would the effect be of running KVM in a Linux instance under z/VM? And of course PR/SM is still dispatching logical IFLs onto real IFLs...or are we eliminating PR/SM on the LinuxONE and perhaps going back to a version of MFT? I will be interested to see the Nürburgring lap times comparing KVM with z/VM. . -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

That's the whole purpose of KVM, on any architecture. What would the effect be of running KVM in a Linux instance under z/VM? Pretty bad performance, to start with. The z/Architecture only provides 2 layers of SIE (start interpretive execution). PR/SM takes up one, z/VM would then take up the second, leaving Linux without that huge boost. And of course PR/SM is still dispatching logical IFLs onto real IFLs...or are we eliminating PR/SM on the LinuxONE and perhaps going back to a version of MFT? Not at all. I will be interested to see the Nürburgring lap times comparing KVM with z/VM. Things will probably not be too different between them at low levels of over commitment of resources. After that, z/VM will blow the doors off KVM. Mark Post -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Linux Without Limits: IBM Launch LinuxONE Mainframes
Linux Without Limits: IBM Launch LinuxONE Mainframes Good news for Ubuntu’s server team today as IBM launch the LinuxONE a Linux-only mainframe that is also able to run Ubuntu. The largest of the LinuxONE systems launched by IBM is called ‘Emperor’ and can scale up to 8000 virtual machines or tens of thousands of containers – a possible record for any one single Linux system. The LinuxONE is described by IBM as a ‘game changer’ that ‘unleashes the potential of Linux for business’. .Continued at http://www.omgubuntu.co.uk/2015/08/ibm-linuxone-mainframe-ubuntu-partnership Mark T.

From what I can tell, the Emperor is a z13 with only IFL engines and modified color scheme. The Rock Hopper would be the new business class z13, with only IFL engines and new color scheme. As always, IBM marketing does more to confuse the people who need to work with this stuff than anything else. Has KVM always run on z or is that new today too? KVM has been available on z for a while now. SUSE introduced it as a Technical Preview back in 2012 with SLES11 SP2. I've been giving presentations on it at SHARE for a while now. From what I've been hearing, IBM has been working with the open source community to get a few more of the features running on z that have been available for a long time on x86. It appears their KVM offering also comes with some monitoring capability, although I haven't seen any details there. As part of the announcements today, SUSE has stated that we will officially support SLES 12 systems running on IBM's KVM hypervisor. I haven't seen anything about Red Hat support as of yet.

Re: Linux Without Limits: IBM Launch LinuxONE Mainframes
Evening all, pray tell what is sort-of? KVM/QEMU and it's derivatives have been around for rather a long time in the unwashed/tamatotchi world. zKVM is nothing more than an attempt by IBM to make a hypervisor palatable to a generation that do not have the know-how or indeed, the discipline to create/maimntain such a beauty as z/VM (CP 64-67 or indeed, VM/BSEPP, Matisse, Sartre. Can such things happen?? - Asks a Luddite? The Germans have a lovely expression for this generation, perhaps the epoch we live in today - Die Wegwerf Generation - The throw-away generation / Pizza / Mc Donalds etc.) Tis indeed sad, me being but a very young child of the sixties. For purely informational purposes, I actually work in BB-DE. Those who work in the lab will know where I mean.

I have seen some 'extreme examples of gyrations' to keep MSU costs down. I wonder how they would implement this? The equivalent of the SCRT report each month for measured usage billing generated from each of the 1000's of linux images running on an 'Emperor'?
