As z/VM 5.1 was never tested on a z196 we cannot provide an outlook of how it will behave. However, given the nature of changes made to z/VM 5.4 and 6.1 to support z196, you may encounter unexpected, undesirable side effects. Given upgrading to z/VM 5.4, or better yet 6.1, is straight forward, why not pursue this avenue rather than rely on knowns? Best Regards, Les Geer IBM z/VM and Linux Development
