That's how Eve works, each node requires certain resources cores and ram. You need figure out what nodes and how many of those you want to run per 1 lab and then you put that number into Resource Calculator and you will see total cores and ram. https://www.eve-ng.net/index.php/download/#CALC
Based on that information you should search for a server that has enough cores/ram.
