For the first problem, I wanted to implement this in the xend rc.d
script, but I haven't made it yet... (maybe this week).

I use the following in /etc/rc.local:

# NetBSD/Xen
echo
echo -n "Starting Xen VM1:"
/usr/pkg/sbin/xm create /usr/pkg/etc/xen/nbsd1 > /dev/null 2>&1 &
if [ $? -eq 0 ]; then
        echo " done."
else
        echo " failed."
fi

echo "Xem VM1: Waiting 5 seconds to finish the boot process..."
sleep 5

echo -n "Starting Xen VM2:"
/usr/pkg/sbin/xm create /usr/pkg/etc/xen/nbsd2 > /dev/null 2>&1 &
if [ $? -eq 0 ]; then
        echo " done."
else
        echo " failed."
fi

You can call "xm shutdown -a" in /etc/rc.shutdown and "sleep" for
the second problem.

I don't know if there are better ways... anyway hope that
helps you.
