Sorry, the first poster had it right. MVS (now OS/390, as you point out) is the other S/390 operating system. MVS (OS/390) can't run a virtual machine, and can't run Linux. VM's purpose is to run many, many virtual machines, and you can run an OS in any of those virtual machines. CMS, VMS, OS/390, Linux, other VM systems, all on the same box. But all this has been covered elsewhere.
