Hi, Sunny.
Some sites have guest naming standards (Linux guests are named LIN....
or LS....., etc.) that would allow you to very simply see which guests
were running Linux, as opposed to CMS or GCS. If your site doesn't have
such a standard, then I'm afraid you're going to have to do this the
hard way.
I would download and install the TRACK z/VM utility; for each guest on
the system, it can tell you what the IPL statement was, and if all of
your Linux guest were IPLed off of a known DASD address, that would tell
you which ones are indeed running Linux. To verify that the guest is a
Linux one, TRACK can also display the kernel parm line, which is stored
at a fixed location (x'1000'?) in the guest.
This isn't too difficult to do for a handful of guests, but if you have
a lot to query, you might want to consider automating this task via some
Rexx TRACK macros.

You can also use the ping test
or "q nss user cms" and "gcs" assuming they don't "ipl 190". any one not
in the list ... chances are LINUX

Subject: How to tell how many linux running on z/VM?
I was asked to find out how many linux guests are running on our z/VM?
the cp commands:Q N is not very suitable for this question.
What is the better way?
