The workaround used to fix this on OpenStack provider.

1. Add a new interface to your VM:

vi /etc/network/interfaces.d/juju-br0.cfg

# The primary network interface
auto juju-br0
iface juju-br0 inet dhcp
bridge_ports eth0

2. In /var/lib/lxc/juju-machine-23-lxc-0/config:

lxc.network.link = juju-br0

3. Go to your dhcp namespace (sudo ip netns exec
qdhcp-b9c1579d-79e2-4215-8ba0-ee4649d9c38f bash on this machine):

3.1 Add the new entries to
/var/lib/neutron/dhcp/b9c1579d-79e2-4215-8ba0-ee4649d9c38f/hosts

3.2 Restart the dnsmasq process with:
kill -HUP $PID

3.3 Restart the ubuntu hosts that contain the lxcs
