Install lxc container
I using ubuntu to host containner so for quick Install lxc container using apt.
alex@Alex-Laptop:~$ apt-get install -y lxc
Download images for container
after we install lxc now we must download images.
alex@Alex-Laptop:~$ sudo lxc-create -t download -n [images-name] -- --dist ubuntu --release trusty --arch amd64
for thats command Iam download distro ubuntu with realese trusty and 64bit
if process done you can see your image with sudo lxc-ls --fancy
NAME STATE AUTOSTART GROUPS IPV4 IPV6
[images-name] STOPPED 0 - - -
Running Images
for starting images you can use this command.
alex@Alex-Laptop:~$ sudo lxc-start --name [images-name] --daemon
this will be start with daemon mode you can see the images now running with ip 10.0.3.164
NAME STATE AUTOSTART GROUPS IPV4 IPV6
[images-name] RUNNING 0 - 10.0.3.164 -
if you want AUTOSTART when container down you can change configuration like below.

...
lxc.start.auto = 1
...
alex@Alex-Laptop:~$ sudo lxc-ls --fancy
NAME STATE AUTOSTART GROUPS IPV4 IPV6
[images-name] RUNNING 1 - 10.0.3.164 -
append lxc.start.auto = 1 to config and you can change ip address in that config files.
