AllGamer Posted May 16, 2016 Share #2 Posted May 16, 2016 I believe that's Virtual Box limitation, not quite a XPEnology limitation. the Free version of VMware ESXi also has the limitation of 8 CPUs (cores) if I recall properly. Now, why do you want to use more that 8 CPUs? just so you know, most Applications does not benefit from more than 2 to 4 Virtual CPUs, you don't really gain that much performance or computing power, it actually has the opposite effect. Having more Physical CPU / Cores only makes sense to split them into smaller amounts to concurrently running Virtual Machines, but if you assign all CPU / cores to the same VM then you might as well dedicate the entire server just to that machine you are trying to run, instead of having it virtualized.
