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 much for a single linux image but you might want to run more Linux images. Shops usually start running more guests once they've installed the first one. z/VM makes your life so much easier when running multiple guests and it enables you to take advantage of the resource sharing (less hardware running more Linux images). It's the reason most Linux and z/VSE systems run in a z/VM. Don't think as z/VM as an OS (though it obviously is an OS) but as a means to build you virtual datacenter. I don't think it's wise to have z/VM running Linux and z/OS load in the same LPAR. Reason for this would be a license issue. The CP costs more than an IFL and when running z/OS and Linux in the same LPAR you might have to pay a z/OS license fee for the Linux load you run. So at the very least, use two LPARs, one with a CP for z/OS and one with an IFL for Linux. (and preferably z/VM in the Linux LPAR) Regards, Berry. > -----Original Message----- > From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of > Spring, David > Sent: donderdag 26 juli 2012 14:28 > To: LINUX-390@VM.MARIST.EDU > Subject: z/Linux and z/OS > > Good morning all, > > Hope this is the right place to ask this question.
