This is absolutely normal: unlike VM virtualization, containers can benefit from available and not used memory on the host and use it e.g. for disk caches.
<div>So kernel always tries to keep Free memory as low as possible by caching as much data as possible. It's good for performance.</div>

I have a query on openvz installation and management. It would be of great help if any body can help me out. I have posted the same question in many forums, but couldn't find a solution.<br>

We have purchased a dedicated server with following configuration </p>
<p>32GB RAM (64GB SWAP) 16 core (Processor: Intel Quadcore E5420)</p>
<p>After that we have installed openvz kernel and hosted 13 VPS on it. </p>
<p>The issue what are facing is, i have allocated only 21GB RAM for all the VPS. However, the hardware, it is showing only 1113MB memory left!</p>

<p>We are using solusvm control panel to manage the vms and in the node limit I have set the following limits</p>
<p>Max Memory: 32 GB Max Disk: 1 TB</p>
<p>WE have also set bustible RAM as same as the actual RAM for all the VMS.</p>
<p>Can anybody tell us what is the issue? Is it normal with openvz virtualisation ?</p>
