A short how-to about moving LXC containers from a computer to another
Stop your container!!
sudo lxc-stop -n <YOUR-CONTAINER-NAME>
Compress it into a tar archive
sudo tar --numeric-owner -czvf lxc.tgz /var/lib/lxc/<YOUR-CONTAINER-NAME>
Move tar file to new host.
You can use scp, an usb stick, whatever you want.
Untar your container where you like, usually /var/lib/lxc is a good place
sudo tar --numeric-owner -xzvf lxc.tgz
Enjoy!
sudo lcx-start -n<YOUR-CONTAINER-NAME>
