That did the trick. Adding this entry to my default.conf resulted in a 
lxc.network.hwaddr entry to be added to my container's config file. I 
also tried using

lxc.network.hwaddr = 00:xx:xx:xx:xx:xx

in my default.conf as well and that generated a random mac address 
starting with b6:38, then 78:47, and so on. Is there a recommended 
prefix for the auto-generated lxc mac addresses?
