I'm not sure as it relates specifically to XEN - but I would have a look through the /etc/rc.d directory. If it's not being turned on there, 'egrep -i iptables' /etc/init.d/* and see if it's in any startup script there. Slim chance they may be something in rc.local as well.

I have a xen machine that has iptables turned off, and after a reboot it started behaving badly during times when network IO rose to anything other than almost nil. Since I know iptables makes xen unstable without some additional config and since its isolated I just have is disabled. As a result it was the last place I looked and spent the better half of the day chasing my tail.
Somehow it gets turned on after a reboot, how can I deduce what is activating it?
Thanks! jlc
