As usual, I don't know anything about what VMWARE can or cannot do. I'm s

Do you have Reed Mullen's presentation? I can't remember where I saw it
last, but it covers the different flavors of virtualization. There was also
another at SHARE in Aug that compared/contrasted the various kinds of
virtualizatoin.

Rob, you must be getting old: still writing EXEC1 or EXEC2 code;-)
- EXEC1 read continiously from disk
- EXEC2 had a buffer (could store the whole EXEC by coding BUFFER *)
But, REXX execs are completely loaded in storage before execution starts.
Apart from that I share your thoughts: CMS waits to

Starting point should be the presentations that Reed Mullen does at
various events on the value of z/VM for running Linux workloads, and
the comparison between z/VM and
TAPEMAP. Should be available on any of the VM Workshop tapes; won't
report density correctly on post-3490 drives, but will produce a summary

What Rob said. (Which I know that you know, but which
bears repeating and deserves to be heard by your architect.)
Don't make out like z/VM is a silver bullet, but be clear that
z/VM is a powerful weapon in his arsenal.
Also: I like to draw illustrations from other platforms.

I recommend use of the term insertion loss instead of overhead.
The term comes from telecomm. The affect arises from any number of
JUSTIFIED additions to a transmission line which naturally introduce
attenuation of the signal.
Add a noise filter? It will reduce noise (which you want)

One thing that really bothers me about VMWARE. When I ask about performance to the people
that measure, they tell me the VMWARE contract specifically states they are not allowed to
talk about it's performance. A vendor that won't let people talk about performance must
