Xen''s network-multinet script is gaining popularity and will reportedly
be the default in the next OpenSuSE release.
The script takes the remarkable steps of clearing the Netfilter ruleset 
   on ''xend start'' and restores it on ''xend
stop''.
Given that xend is started at stage 13 and Shorewall at stage 6, this 
means that ''xend start'' effectively isolates the system (the
stupid
script doesn''t change the policies associated with the built-in chains 
which are set to DENY by Shorewall).
I''m not going to change Shorewall to deal with this madness. My 
recommendation is:
a) If you want to use NAT with a domU, then let Shorewall do it; don''t 
use Xen''s NAT.
b) Either:
	Edit /etc/xen/scripts/network-multinet and delete or comment out
         all calls to ''manage_iptables''.
    or
	(RPM-based systems) Edit /etc/init.d/shorewall[-lite] and 	
	change:
		# Should-Start: VMware
    	to
		# Should-Start: VMware xend
    	Note that this last choice will start all of your servers before
    	starting Shorewall -- you''ve been warned.
