John,
When you shutdown your linux guest, do you use a "CP SIGNAL SHUTDOWN"
command to tell linux to shutdown, or do you manually shutdown linux.
Our manual shutdown appears to work, but when we try to automate it with
the "CP SIGNAL SHUTDOWN" from vm; linux appears to send a response to vm
saying it has completed shutdown; but appraently it really hasn't.
Thanks, Bob

We start/stop oracle with an init.d script so oracle's start/stop is
part of Linux's boot and shutdown sequence.
