Delete everything from here ...

to here, and instead setup your IP addresses from the container OS
configuration script (e.g. /etc/network/interfaces,
/etc/sysconfig/network-scripts/ifcfg-eth*). That should give only one
interface, and you can configure eth0:1, eth0:2, etc from inside the
container.


If you instead want eth0, eth1, eth2, etc, then repeat the network block
block several times, e.g.

lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.hwaddr = <MAC1>

lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.hwaddr = <MAC2>
