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. It will never really need this amount of memory. There is no reason to configure the heap for 16gb.

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". Please open a bug with all the details, we should address that. Currently we are tuning the java heap size to 1/4 of the system memory. On hosted-engine-setup side we propose to assign to the engine VM 16GB (so java heap = 4GB) as recommended and 4GB as a minimum suggested value.

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