     adb push lxc-android.tar.gz /tmp
     adb shell tar xvzf /tmp/lxc-android.tar.gz

Create directory for the system container and extract rootfs into its location.

Tips and tricks

When you try to start container second time, it doesn't allow you to login in. To work around this, From adb shell

 rm /data/lxc/containers/system/rootfs/etc/init/lxc-android-boot.conf
 vi /data/lxc/containers/system/rootfs/etc/fstab
 # remove the all mount points that says "added by lxc-android-boot except one with /vendor"
