16GB is just the recommended amount of memory. The more items your Engine has to manage, the more memory it will consume, so whilst it might not be using that amount of memory at the moment, it will do as you expand your cluster.

Hello folks

I have a Engine dedicated machine running with 4GB of memory. It has been working fine without any apparent issues.

If I check the system memory usage it rarely goes over 1.5GB.

But when I upgrade oVirt Engine it complains with the following message: "[WARNING] Less than 16384MB of memory is available".

Why is all that required if the real usage doesn't show that need ? Or am I missing anything ?
