Abstract: A system is provided and includes a plurality of machines. The plurality of machines includes a first generation machine and a second generation machine. Each of the plurality of machines includes a machine version. The first generation machine executes a first virtual machine and a virtual architecture level. The second generation machine executes a second virtual machine and the virtual architecture level. The virtual architecture level provides a compatibility level for a complex interruptible instruction to the first and second virtual machines. The compatibility level is architected for a lowest common denominator machine version across the plurality of machines. The compatibility level includes a lowest common denominator indicator identifying the lowest common denominator machine version.
