This doesn't work here. If I do
/etc/init.d/dnsmasq stop virsh net-start default I have: # ps awux | grep dnsm nobody 6327 0.0 0.0 5784 1080 ? S 08:47 0:00 dnsmasq --keep-in-foreground --strict-order --bind-interfaces --pid-file --conf-file --listen-address 192.168.122.1 --except-interface lo --dhcp-leasefile=/var/lib/libvirt/dhcp-default.leases --dhcp-range 192.168.122.2,192.168.122.254 If I have dnsmasq already running I have: # ps awux | grep dnsm dnsmasq 6373 0.0 0.0 5780 696 ? S 08:48 0:00 /usr/sbin/dnsmasq -u dnsmasq -r /var/run/dnsmasq/resolv.conf root 6457 0.0 0.0 0 0 ? Z 08:49 0:00 [dnsmasq] <defunct> because (this is what libvirt basically does): # brctl addbr virbr0 # ifconfig virbr0 192.168.122.1 # dnsmasq --keep-in-foreground --strict-order --bind-interfaces --pid-file --conf-file --listen-address 192.168.122.1 --except-interface lo --dhcp-leasefile=/var/lib/libvirt/dhcp-default.leases --dhcp-range 192.168.122.2,192.168.122.254 dnsmasq: failed to bind listening socket for 192.168.122.1: Address already in use One can partially work around this by using: DNSMASQ_OPTS=-z in /etc/defaults/dnsmasq but even this only works as long as you don't restart dnsmasq. There are two possible solutions I can think of: * Using conf-file multiple times and running only one dnsmasq instance per defined libvirt network (we'd need to restart the daemon when new networks come up) * have the default dnsmasq instance ignore virbr* interface via a new commandline switch and have this instance use -z by default. However, I'd still be interested why this works for you. Cheers, -- Guido -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
