Mark, we actually tried CP TRACE statement to let an OS/390 2.4 start under Z/VM 5.3 on a Z9 CPU, and it runs.... Provided that (as per our experience): 1 - you don't define more than ONE CP to the virtual machine; 2 - you don't assign more than 512MB of central storage to the virtual machine;
under these assumptions, IPL was completed and all was up and running.

You need at least OS/390 2.10 or higher plus the add-on compatibility and/or exploitation support. http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/FLASH10236 You can also search the archives. There was a post in April 2006 and from Jim Mulder that suggested that this VM setting might get around the problem, but I don't recall anyone ever reporting that it worked or not: #CP TRACE IPTE RUN NOTERM http://bama.ua.edu/cgi-bin/wa?A2=ind0604&L=ibm-main&D=1&O=D&P=16015 ... snip _________________________________________________________________________ Paolo Cacciari IBM Italia S.p.A.
