Hello everybody, i've defined a simple network, with no dhcp. I'd like to use dnsmasq only as a dns server. $ virsh net-dumpxml basicswitch <network> <name>basicswitch</name> <uuid>60f491d2-d6c4-6b57-8a50-081cace8dedc</uuid> <forward mode='nat'/> <bridge name='virbr1' stp='on' delay='0' /> <ip address='192.168.100.1' netmask='255.255.255.0'> </ip> </network> I start it : $ virsh net-start basicswitch Network basicswitch started $ virsh net-list Name State Autostart ----------------------------------------- basicswitch active no But i see no dnsmasq process : $ ps fax|grep dnsmas[q] Here the output of "virsh version" : $ virsh version Compiled against library: libvir 0.8.8 Using library: libvir 0.8.8 Using API: QEMU 0.8.8 Running hypervisor: QEMU 0.12.5 What is funny is that the dnsmasq process is created on another box with different version : $ virsh version Compiled against library: libvir 0.8.3 Using library: libvir 0.8.3 Using API: QEMU 0.8.3 Running hypervisor: QEMU 0.12.5 $ ps fax|grep dnsmas[q] 7104 ? S 0:00 dnsmasq --strict-order --bind-interfaces --pid-file=/var/run/libvirt/network/basicswitch.pid --conf-file= --listen-address 192.168.100.1 --except-interface lo Any advice on it ?
