This is the environment that we work in. z/VM 5.2, a couple z/OS (1.4
in production, going to 1.7 RSN), several test z/OS (some 1.7, some
1.8, some 1.5 - don't ask), 600+ Linux virtual servers.
I would say we have an outstanding problem related to 5.2, but not
related to running z/OS and Linux on the same hypervisor. Our
problem is a load-related performance problem and involves DB2 for VM.
It's a fairly specific to some unique aspects of our environment
and not related to running both z/OS and Linux on the same z/VM.
There were some significant memory improvements in 5.2 for handling
the 2GB bar.
It's currently on a z900, going to z9 at the end of the year.
