No. One of the primary differences between System z virtualization and other platforms is that z/VM and LPAR give the guest access to the real hardware. It is what it is, and there is no provision in the hardware to "trap out" if a guest issues an instruction that exists on the z990, but not on the 9672. Alan Altmark z/VM Development IBM Endicott
