  • Thread-topic: iptables rules added by default

In a default install of xen-3.0-testing, I just noticed that it
automatically adds in some iptables rules when a domain is created. This
is with the default of vif-bridge.

In my case I don't use iptables on this server, so these iptables rules
are completely unnecessary and can't do anything useful for performance.

Does anyone have any comments on how much difference having iptables
loaded makes for throughput, and if this is something we should be
worrying about?
