Public bug reported:
A cloned container will have the same MAC address and IP address with
the original container.
How to reproduce:
1. $ sudo lxc-create -t ubuntu-cloud -n foo -- --release trusty
2. $ sudo lxc-clone foo bar
3. $ sudo lxc-start -d -n foo
4. $ sudo lxc-start -d -n bar
Expected result:
2 container will have different MAC and IP address each other.
Actual result:
2 container will have duplicate MAC and IP address.
