Xen users - Oct 2005 - Supported/normal way of creating domains at start-up?

Hi! I''m a new xen user, and I''ve searched the docs and list
archives,
but I can''t seem to find the "official" or recommended way
for starting
domUs at machine start-up and shutting them down (safely) at
shutdown. What do people normally do ? 

Thanks,
		  ...Eric

put a symlink to the xen domU config files into /etc/xen/auto/

that covers startup, but is there anything in xen to send a signal to init
in the domUs to request a shutdown?

from /etc/init.d/xendomains:
stop()
{
    # NB. this shuts down ALL Xen domains (politely), not just the ones in
    # AUTODIR/*
    # This is because it''s easier to do ;-) but arguably if this script
is run
    # on system shutdown then it''s also the right thing to do.

    echo -n $"Shutting down all Xen domains:"

    xm shutdown --all --wait --halt

    RETVAL=$?

    [ $RETVAL -eq 0 ] && rm -f $LOCKFILE

    on_fn_exit
}

So all domUs are shutdown when you call /etc/init.d/xendomains stop.
Sure, you could change it to shutdown only domUs in /etc/xen/auto/.

As Matus Harvan also mentioned, the init script should handle this too.  It 
sends a shutdown request to each domain, which should shut itself down 
politely and then go away.

Note that "rude" or malicious domains can hold up dom0 arbitrarily
long by not
shutting themselves down on request...  You''ll want to bear this in
mind: you
must a reasonable confidence that the domains won''t do this all the
time, or
at least that you''ll notice and come and kill them.
