It's not VM that's doing it: it's MVS (i.e. the VM guest).

Hmmm... Must be timezone problems. :-)

It's not in VM (CP) code; the CS is in MVS code running in a virtual machine.

CS is an unprivileged instruction, so when MVS executes it, it causes a program check (which Hercules then logs).

Not clear to me why it matters if an instruction program checks because of a protection exception (4) or because it's a privileged instruction (2). Either way it's Hercules that sees it and may report on it.
