Why would you need other instances of the service lxc-dnsmasq? The lxc- net doesn't support instances - there could be only max. one bridge at any given time, and I believe setting two dnsmasq servers on the same network interface would cause conflict.

I also know, that I can read the MAC address of the LXC container (e.g. by looking for lxc.network.hwaddr entry in /var/lib/lxc /<container-name>/config and assign the IP based using entries dhcp- host=<mac-addr>,10.0.3.3 in /etc/dnsmasq.d/<some file>. In the file /etc/default/lxc-net I read # Uncomment the next line if you'd like to use a conf-file for the lxcbr0 # dnsmasq. For instance, you can use 'dhcp-host=mail1,10.0.3.100' to have # container 'mail1' always get ip address 10.0.3.100. #LXC_DHCP_CONFILE=/etc/lxc/dnsmasq.conf That would suit my needs; unfortunately doing so has no effect - at least not until the next computer reboot. I would expect that `sudo service lxc-net restart` forces the dnsmasq to reload - unfortunately it never works. To reproduce: On Ubuntu Trusty 14.04 64bit, 1. install package lxc, 2. create a container (e.g. sudo lxc-create -n mycontainer -t ubuntu -- -r trusty) 3. start it (sudo lxc-start -d -n mycontainer) 4. create another container (e.g. sudo lxc-create -n my2ndcontainer -t ubuntu -- -r trusty) 5. edit /etc/default/lxc-net to uncomment the LXC_DHCP_CONFILE 6. edit /etc/lxc/dnsmasq.conf to contain a line like `dhcp-host=my2ndcontainer,10.0.3.142` 7. sudo service lxc-net restart 8. start the 2nd container (sudo lxc-start -d -n my2ndcontainer) The steps 2 and 3 are optional. The 2nd container never gets the ip 10.0.3.142, but it keeps the assigned dynamic IP Walkaround 1: Turn off the computer and test again tomorrow. Walkaround 2 (more serious, but works only if steps 2 and 3 are skipped): name=my2ndcontainer sudo lxc-stop -n $name >/dev/null sudo service lxc-net stop >/dev/null if [ -d /sys/class/net/$internalif ]; then sudo brctl delbr $internalif >/dev/null #Why? See below. fi sudo rm /var/lib/misc/dnsmasq.$internalif.leases sudo service lxc-net start >/dev/null sudo lxc-start -d -n $name >/dev/null sleep 5 Unfortunately, there is a bug (feature?) in the /etc/init/lxc-net.conf in Ubuntu 14.04 that prevents reloading the dnsmasq unless the bridge device is down for the host.
