And with SHARE coming up soon, that requirement could get relayed to IBM
fairly quickly.  HINT! HINT!

Subject: Re: Unexpectedly closing VM console breaks Linux server under
z/VM

-snip-
IMO, a console disconnect (user-initiated or I/O error) should have no
effect on RUNNING/CP READ state.  It should simply be the equivalent of
FORCE DISC.  If it was running, leave it running.  If was in CP READ,
leave it there.  Forever.  The usual cadre of performance/idle monitors
can decide (based on policy with exceptions) whether the user is
"wasting"
resource.  If I Ran The Zoo, I would introduce new user event records
and
operator messages that indicate a disconnected virtual machine just
entered VM READ or CP READ so as to make it more straightforward for
system automation tools to act.  If I ran the zoo.  And if we had user
requirements to change the behavior.  :-)
