Description Bastien Nocera 2007-12-06 16:41:43 UTC
1. Start host with restrictive firewall
2. Startup a virtual machine on that machine
3. Realise the firewall is blocking access to the physical host
4. run "/etc/init.d/iptables stop"

iptables has wiped the bridge settings from libvirtd

Comment 1 Daniel Berrange 2007-12-06 16:54:27 UTC
It did exactly what you asked it todo - it removed all iptables settings :-)

You can restore rules by sending libvirtd SIGHUP, or 'service libvirtd reload'

Comment 2 Bastien Nocera 2007-12-06 18:11:53 UTC
I figured that. But what about UI apps that rely on simply starting/stopping
iptables once /etc/sysconfig/iptables?

I'm thinking system-config-firewall in particular.

Comment 3 Thomas Woerner 2007-12-11 15:03:18 UTC
I am sorry, but if you stop iptables, all the chains and rules are dropped. This
is intended behavior. s-c-fw does not know about libvirtd, same for all other
firewall configuration tools available.

Closing as "NOT A BUG".
