yes, that's what I missed in the first place ...

precisely, and that's why I suggested to switch to the
plain init style, where the guest runs its own init
which handles the startup and shutdown ...

yes, and we know two things from this test, first
that you guest is working fine (regarding shutdown)
and second that the guest shutdown (runlevel scripts
contain a killall, which, quite naturally, kills off
the external (sysv) shutdown script too ...

except for that fact that you have an additional
process (init) running inside, no ..

no, you can, now that we 'know' what causes it, look
for the script which executes the killall5 (or whatever
is used to kill of all processes) and remove it from
the proper runlevel, which will isntantly fix the kill
and thus make the sysv shutdown work as expected ...

will do so,
