Of course, if your requirement is as simple as "I want to clone this
container in a similar way that virtualbox/vmware can export OVA", you can
simply create an image (e.g. compressed tar file) of your container
directory (e.g. /var/lib/lxc/app1), then copy-and-extract it on the other
machines.

If you use the default lxcbr0 for the container, then you should be all
set, no need to change anything.

If the containers are bridged to your LAN, then at the minimum you need to
change its mac address (on the container config file).
