By itself, one of the ntpd daemons will keep open the stdin/out/err it
was started with, which in this case will be the pipe or tty created
by of the ssh server.
The easiest solution (if there isn't a virtualbox toolset) is to use
the rc.d framework, which will handle the fds:
ssh guesthost '/etc/rc.d.ntpd restart'
and put the -s in ntpd_flags in rc.conf.local
