Greetings all. We are running LXC v2.0.8 on Ubuntu 16.04 and all containers are running identical versions of the application stack (php, php-fpm, nginx, etc). Since each container is running the exact same versions of apps, how can I get the host server to use KSM (kernel same-page merging) on the containers? As you can see below, KSM has been enabled, but no pages seem to be shared.
