Hi,

Where did you get this information from?  There are a few problems
below.  What is your distribution?  What version of lxc are you
using?  Best would be if you could get lxcbr0 created by lxc itself
(see config/init/common/lxc-net)

Here you have eth0 doing dhcp, but you also make it a
bridge-port of lxcbr0 which has a static address.  I suspect
you want to just make it

auto eth0
iface eth0 inet manual

auto lxcbr0
iface lxcbr0 inet dhcp
  bridge_ports eth0

Even so, whether containers get a network address will depend on
how your local network is configured (and it won't work if eth0
is wireless, but I assume it's not)  But that may get you going.
