Just for clarification, it's opinion, not luck. In my *opinion*, these cyberdraculae aren't necessarily suitable for Linux. I said rare. Linux ... without VM ... rare. Not never, just rare. Sheesh!

Is there a free evaluation copy of Linux for z/VM?
Is there a free evaluation copy of Linux for z/VM? There are rumors from those flying at 50,000 feet that we may be asked questions about Linux on z/VM. On the other hand, would it be a proper use of this forum to post the questions here or is there a Linux for z/VM list?

Re: Is there a free evaluation copy of Linux for z/VM?
Hi, Jim. Yes there are free evaluation copies of Linux for z/VM available from the major vendors, plus there are non-commercial versions of Linux for s390Debian, Fedora, Centos, for example. I can point you in the right direction if you would like further information. Yes, the is also a Linux on S/390 mailing list that discusses running Linux on both an LPAR and as a guest of z/VM. To subscribe to the LINUX-390 discussion, send e-mail note to: lists...@vm.marist.edu In the body of the note, write only the following line SUBSCRIBE LINUX-390 your-name-here Have a good one, too.

Re: Is there a free evaluation copy of Linux for z/VM?
There is a mailing list for Linux on zlinux-...@vm.marist.edu Both Novell (SLES) and RedHat (RHEL) can be downloaded at their respective web sites.. you'll be looking for the 's390x' binaries. You can download and use for free (respecting the various GPLs, etc).. and then purchase if you want support and access to updates, etc. There are also other flavors (e.g. CentOS) but if you likely want to stick with SLES or RHEL. Most government agencies I've worked with have been using RHEL on both the mainframe and other platforms.. but that's just from personal experience - I haven't done a survey or anything :) Usually, for ease of migration and support - you stick with the distro you use on the distributed platforms..

Re: Is there a free evaluation copy of Linux for z/VM?
In a word - sharing. In LPAR mode you can run 1 linux per LPAR. Under VM can share the memory, CPU/IFL, DASD and run lots of linux.

Re: Is there a free evaluation copy of Linux for z/VM?
Being the purist, I appreciate that Linux on z can run without z/VM. However ... The value of virtualization is still not recognized in a lot of places and situations. D/R preparedness is a biggie. One D/R plan has most of your app-hosting systems run virtual. So when you bring things up on the recovery HW, the app servers actually see NO CHANGE. Ahhh... But that's just one example. And then there's what Mark Pace said: sharing. Linux is a good system and getting better all the time. But it simply cannot compete with the scalability and robustness of z/VM for sharing physical resources. And the insertion loss of running VM (eg: with just one guest, instead of running that guest native) is so low compared to other hypervisors. It's good that native Linux is an option, but it's rare that I would recommend it. -- R; Rick Troth Velocity Software http://www.velocitysoftware.com/ On Mon, Apr 4, 2011 at 10:55, Ward, Mike S mw...@ssfcu.org wrote: I have a question.
