Thanks, Robert!
I do love to see the code.
And I try to understand what is going on between z/VM and linux.
Any books?

Re: Is it bad to make one zlinux running on 2 z/vm?
The best solution for your problem is to couple the two systems with CSE,
so that they?ll know what the other is doing.
Before we implemented CSE, we created a service we called Janus, which we
ran in the profile of each Linux server during the CMS startup. The
purpose was to look up which system the Linux guest was last started from,
and to report a mismatch if there was a console, or log out immediately if
the image was autologged.
We still run Janus as a double check on things. If you?d like the code, I
can package it for you and explain what it is trying to do.

Thanks folks,
From the answers, I got :
It is bad and must find a way to avoid it happening.
What will happen if one zlinux running on 2 z/VM?
There is a IP conflict and dasd R/W conflict.
So it is the same as running two linux server sharing the same IP and the
same disks?
And z/VM has done nothing with it.
Does my understating is correct?
