It depends but for us Yes. If 3 Linux images was to become 30 images for
production z/VM is mandatory since I don't have a z9 sitting around and we
run some other work.
What has not been mentioned is that if you don't have z/VM automation of
many images becomes much more complex. What's the point of centralizing
many servers on one footprint if you don't have good virtualization. LPAR
will share CPU but not memory. $10K @ GB although if you spring for a z9 I
think it's discounted to $8K @ GB. LPAR still falls short when compared to
VM in many respects.

Are You saying that from a management and/or operations view, z/VM is
mandatory to get full/enough value out of deploying Linux on zSeries ?
