I know what Red Hat states is the minimum, they state here: https://access.redhat.com/articles/rhel-limits that 1 GB is the minimum. However, at first glance, that number seems made up. I can't afford to allocate that much memory to every instance of the operating system. What is the actual overhead of the base os?
