Thanks Tom, Justin,

Bug #227011 explains what I'm experiencing.

This technology has great potential to be used in mission-critical systems, but issues like this one might be holding back its success.

I hope a suitable solution can be found soon ...

Thanks again,

Daniel

libvirt has no sane was of integrating with iptables

We simply need a way to say to iptables "we've added these rules, please
load them when you restart" without overwriting the current configuration.
We also need lokkit/system-config-firewall to not overwrite these rules when
the user modifies the configuration.

The whole sorry saga is well documented in bug #227011
