No zSeries Machines provide 370 mode (370 mode got removed in some of te latest 9672 generations). To be able to use a MACHINE 370, 370 mode must be provided by the HW, Running VM/ESA as guest of z/VM will not help. The solution/bypass to allow running CMS 370-mode applications in XA-mode machines was the 370 Accommodation feature, activated with SET 370ACCOM ON. I don't remember in which VM/ESA release it first appeared, nor in which release it was improved. The latest (and still available version) is a co-operation between CMS and CP. It has been discussed here recently.
