How is the static ip address assigned?  Using raw.lxc, using dhcp config
on the host, using /etc/network/interfaces or the like in the container's
rootfs?

How are you currently copying it?  Are you using lxc copy --stateless?
Can you just pass '-c <config>' to the lxc copy command to change the
ipv4 configuration?
