Oh my.
I mean, I know that OS (and descendants--for those of you without this particular trauma,
we mostly mean MVS (now z/OS), but of course there's OS/MFT, OS/MVT, and then OS/MVS)
was always trying to kill VM, and we went through similar crap with Linux/390 (and
zLinux), which contains code to let it run directly on the iron, even though even
production shops are not going to *do* that (OpenSolaris-for-z required VM underneath it;
hell, it required a couple new DIAGs we requested).
That actually makes it easy to run zLinux on Hercules, so I'm not complaining,
but...it's not how any shop running it as anything other than a curiosity would do
it. I mean, OK, I guess you could have a teeny little LPAR but let's face it the
LPAR is basically VM.
But TSS was always *also* an also-ran (that is, not OS). It's really weird (to me,
anyway) to see it was hostile to VM too.
