CP choose what operator console to use by looking through the
devices listed in the Operator_Consoles statement in
SYSTEM CONFIG (or overriden by CONS=nnn via SAL).
The difference you saw would happen if VMTEST had your console
address listed in Operator_Consoles (or CONS=0009 stamped into
the SAL settings via SALIPL) and VMNEW did not. VMNEW would then
fall through to the "System_Console" which usually sits at the
end of the Operator_Console list and prompt you via SCLP/VINPUT.
