There is no special ways to determine the hardware levels. There is no checking of CPU ids etc. Simply the compiler default architecture is set to zEC12 across the board, meaning that glibc, kernel, and most binaries rely on zEC12 only instructions. I do not believe these are at all available, in full, on non zEC12 hardware. In other words it's not possible to "fake" CPU id in Hercules / zPDT / z/VM / z/KVM, as things simply segfault / fail with illegal instructions at runtime. If future revisions of those virtual machines implement zEC12 instructions, on pre-zEC12 hardware, one would be able run Ubuntu 16.04 there.
