Good morning all,
Hope this is the right place to ask this question. Please pardon the intrusion
if I should be posting this someplace else.
Our management is considering the acquisition of a new z114 sandbox system
primarily for testing new hardware (DASD and tape). They would also like to
Sure, that's how we got started. Brought up Redhat on a spare lpar sharing part
of a regular CP. Then got a trial version of z/VM from IBM and management was
more or less sold on the z/VM-zLinux configuration.

We had offering as well...but went right to z/VM for Linux..z/OS in
3lpar's..now considering z/VM with all of it under it's hat..This is being
done today with our DR sight provider and proved to be very useful..

You've come to the right list. Welcome to the party!

Hi David,
This is the right place for this question.
You should not have any problems with running z/OS and z/Linux on the
same machine in separate LPARs, aside from common problems with running
ANY two operating systems together on one box using LPARs (memory and
CPU allocation, etc).

Hi, David.
Yes this is certainly the right place to ask such questions; welcome.
While I usually recommend installing z/VM for zLinux PoCs to my clients,
you can indeed create an LPAR and run (only one copy of course) zLinux
in it, with other LPARs running z/OS.
BTW, this list and the one
We just put in a 114 and run z/OS on 2 LPARs and z/VM on 2 other LPARs with
several guests under the VMs
As a POC your approach will work but there are a few things to consider for the
long run.
1) Unless you are running your CPs at full throttle, Linux will do much better
on IFL engines which

The short answer is yes,
zLinux can run Natively on a standard processor.
IBM recommends that in a production environment z/VM is used. The main reason
is that is is much easier to create a new guest under VM than creating a new
LPAR.

Florian, thanks for the reply.
Another though. Don't run z/OS under z/VM, use the new lpar with z/VM and
zLinux and leave the z/OS lpar alone. Setup hipersockets between the 2 lpars
and you have isolation and at the same time FAST communication between the two.

also like to conduct a z/Linux POC using the same machine. I know that
z/Linux can run in native mode on a System z processor but I wasn't sure
about it
Hi David,
It's the perfect place to ask. Yes, you can run it alongside an z/OS. It's a
different LPAR and usually even a different CPU type. You need CP for z/OS and
usually run IFL for zLinux. (though a Linux machine still can run on CP)
Indeed, I would advise to run Linux in z/VM. Not so
A week or two back, someone (I think it was Florian Bilek) asked why there was
a delay between invoking chccwdev and the device becoming available, and
whether there was an option or command that would exit only when the device was
actually available. There was some discussion of the --settle

I wouldn't go that far to state that IBM recommends a production
environment to be z/VM based.
Whether z/VM or PR/SM is more appropriate depends whether the runtime
characteristics of the application workload benefits more from the reduced
overhead PR/SM LPARs imply or from z/VM's capabilities to

Hi David,
Thank you for bringing up this topic again. No, unfortunately there was no
other solution than to rerun the commands.
I think there should be an option for chccwdev to wait till DE/CE is
received and not to terminate with device busy.
Kind regards,
Florian
