Для регистрации автоматического запуска контейнера, создайте символическую ссылку /etc/default/lxc/name.conf, указывающую на конфигурационный файл контейнера. Например, конфигурационный файл для контейнера CN - /var/lib/lxc/CN/config. Чтобы автоматически запускать этот контейнер, используйте команду: 

sudo ln -s /var/lib/lxc/SAV-centos/config /etc/lxc/auto/SAV-centos.conf
