Store the PSW as DEAD, and the virtual machine goes DEAF. Makes
complete sense to me (in accord with the POO).
Then with CONCEAL set on, everything went "FFFFFFFF" (too bad

can use:
SYSTEM CLEAR
SYSTEM RESET
DETACH CPU
DEFINE STORAGE
SET MACHINE
or the guest itself can load a disabled wait PSW (that's what
BEGIN 0
causes).
