[Bug 1362224] Re: local provider creates all containers with the same MAC address

[Martin Pitt]

I believe that is a bug/regression in LXC itself. The lxc-clone manpage
says

       -M, --keepmac
              Use the same MAC address as the original container, rather than generating a new random one.

If I clone an existing container

$ grep hwaddr /scratch/lxc/juju-trusty-lxc-template/config 
lxc.network.hwaddr = 00:16:3e:c4:4e:24
$ sudo lxc-clone -o juju-trusty-lxc-template -n test

then the cloned container has the same MAC address instead of a random
one:

$ grep hwaddr /scratch/lxc/test/config 
lxc.network.hwaddr = 00:16:3e:c4:4e:24

** Package changed: juju-core (Ubuntu) => lxc (Ubuntu)

** Changed in: lxc (Ubuntu)
     Assignee: (unassigned) => Stéphane Graber (stgraber)

** Summary changed:

- local provider creates all containers with the same MAC address
+ lxc-clone does not randomize MAC address - juju-local machines have same IPs
