Gary,
It depends on your hardware. From Bill Bitner's z/VM System Limits
SHARE presentation:
Virtual machine size:
- Supported/Tested 1 TB (240)
- Hardware limits
* z10 8TB
* z9 1TB
* z990 256GB
* z900 256GB
That's for one virtual machine. There's also a guest real limit of 8 TB

The thread on mixed paging volumes caused me to ask the question. I should

There is also that intangible factor of how each of those 4GB guests make

That's why 'how many xxGB guests can I run within the maximum architectural

CP doesn't keep the maximum size in the VMDBK. Have you ever noticed that
you don't have to logoff/logon after you raise the maximum in the

It really wouldn't be too hard to have something like
QUERY VIRTUAL STORAGE DEFAULT : MAXIMUM
