Changes to the daemon to make it called qemudShutdown() broke the network driver when run in --daemon mode. This is because the main daemon forks into the background, and the original PID then exits destroying any active networks & removing the iptables rules. # /usr/sbin/libvirtd --daemon Shutting down network 'default'iptables: No chain/target/match by that name iptables: Bad rule (does a matching rule exist in that chain?) iptables: Bad rule (does a matching rule exist in that chain?) iptables: Bad rule (does a matching rule exist in that chain?) iptables: No chain/target/match by that name iptables: No chain/target/match by that name iptables: Bad rule (does a matching rule exist in that chain?) iptables: Bad rule (does a matching rule exist in that chain?) iptables: Bad rule (does a matching rule exist in that chain?) iptables: Bad rule (does a matching rule exist in that chain?) Failed to bring down bridge 'virbr0' : No such device Failed to delete bridge 'virbr0' : No such device or address The core issue is that when forking into daemon mode the original process should immediately exit & not do invoke cleanup functions. This patch makes it do that Dan.
