I'm using CentOS 5.4 as kvm dom0.
I have couple domU (sles 11.0) running on this box. I configure domU's
network using dom0's bridge ... all domU and dom0 are on the same network.
Whenever I re-configure dom0's firewall (/etc/rc.d/init.d/iptables restart), the
domU will stop working and can't connect to Internet. I restart domU's network
service (/etc/rc.d/init.d/network restart) but that still can't re-enable domU's network.
How can I fix this problem without reboot dom0 ?
