[libvirt-users] /proc/meminfo

[Peter Steele]

Has anyone seen this issue? We're running containers under CentOS 7.2 
and some of these containers are reporting incorrect memory allocation 
in /proc/meminfo. The output below comes from a system with 32G of 
memory and 84GB of swap. The values reported are completely wrong.

# cat /proc/meminfo
