Scott I can reproduce the restart issue, but using start/stop dnsmasq was restarted:
ubuntu@server-15281:~$ ps axw | grep dnsm 5367 ? S 0:00 dnsmasq -u lxc-dnsmasq --strict-order --bind-interfaces --pid-file=/var/run/lxc/dnsmasq.pid --conf-file= --listen-address 10.0.3.1 --dhcp-range 10.0.3.2,10.0.3.254 --dhcp-lease-max=253 --dhcp-no-override --except-interface=lo --interface=lxcbr0 ubuntu@server-15281:~$ sudo stop lxc-net lxc-net stop/waiting ubuntu@server-15281:~$ ps axw | grep dnsm 5409 pts/0 S+ 0:00 grep --color=auto dnsm ubuntu@server-15281:~$ sudo start lxc-net lxc-net start/running ubuntu@server-15281:~$ ps axw | grep dnsm 5425 ? S 0:00 dnsmasq -u lxc-dnsmasq --strict-order --bind-interfaces --pid-file=/var/run/lxc/dnsmasq.pid --conf-file= --listen-address 10.0.3.1 --dhcp-range 10.0.3.2,10.0.3.254 --dhcp-lease-max=253 --dhcp-no-override --except-interface=lo --interface=lxcbr0 I did get confused by the duplicated configuration entries for network ranges in /etc/default/lxc and /etc/init/lxc-net.conf. Marking 'Low' as I think it only impacts the restart case - which can be worked around using stop/start lxc-net. ** Changed in: lxc (Ubuntu) Status: New => Confirmed ** Changed in: lxc (Ubuntu) Importance: Undecided => Low ** Changed in: lxc (Ubuntu) Status: Confirmed => Triaged ** Also affects: lxc (Ubuntu Precise) Importance: Undecided Status: New ** Also affects: lxc (Ubuntu Quantal) Importance: Low Status: Triaged ** Changed in: lxc (Ubuntu Precise) Status: New => Triaged ** Changed in: lxc (Ubuntu Precise) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1043588 Title: sudo restart lxc-net does not kill/restart dnsmasq To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1043588/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
