I know I don't want arbitrarily random mac addresses, I was asking what 
is the recommended lxc prefix? A previous poster suggested

00:16:3e:xx:xx:xx

I decided to try

00:xx:xx:xx:xx:xx

just to see if lxc would pick its own hard coded prefix but it seemed to generate something different each time. You recommended that I should use the one that is set by default, but what is that? My default.conf had no entry lxc.network.hwaddr until I put one there.
