I've seen this behaviour with LXC when running systemd inside the
container. /proc/meminfo is generated by a FUSE process libvirt
runs and determines the memory settings by reading the root cgroup
for the container. What I think is happening is that systemd is
reseting the memory limits in the root cgroup, so the values that
libvirt set are no longer present. This in turn causes us to report
the wrong data in /proc/meminfo. I've not yet decided whether this
is a systemd bug or not though.
