Hello, Openstack host show compute-host, shows more memory allocated to instances than actual physical memory, although the memory allocation ratio is 1.0 in nova.conf, the same is also shown in horizon dashboard hypervisor statistics. We can see this in many compute nodes in the cluster. Also these statistics does not match with free -g or cat /proc/meminfo. For Example : Memory_mb | compute-node23 | (total) | 257915 | | compute-node23 | (used_now) | 271360 | | compute-node23 | (used_max) | 267264 | How to avoid misleading statistics, also which statistics are actually correct? versions : openstack : Stein nova : 2:19.3.0-0ubuntu1~cloud0 Regards, Akkina
