As far as I know, that's normal – /proc/meminfo always reflects the total amount of memory, regardless of cgroup limits. LXC uses lxcfs to mount a fake meminfo file there, nspawn doesn't have an equivalent.

I used "systemctl set-property systemd-nspawn@my-container-real-name.service MemoryMax=2G", to test defining a limit on RAM usage of a nspawn container.
But after setting the limit, with the config being created at "/etc/systemd/system.control/" correctly, when I start the container and enter on it, the "free" command still shows the memory info from the host.
Is this correct? If yes, is there a way to make the container to show only the memory separated to it?
