'shutdown -h now', or triggering the same via SIGNAL SHUTDOWN with
proper init scripts to start/stop applications. Oracle does data caching
as well as the caching that Linux does, so it's doubly important that
you get everything flushed to disk and shut down properly before the
guest goes away.

You should have an init script in /etc/init.d that both starts and stops
the Oracle instances that matches the conventions of your Linux
distribution. I wrote and posted some examples to this list, since
Oracle doesn't seem to come with them.
