Ah ... of course. As for the rest of your kind explanation - I'm well aware of that. If you over-provision, you have to take responsibility and at least monitor usage closely (Observium, Munin, ...)

Thanks again, will go the ZFS route, set up the system with the 16 GB RAM it has, then upgrade to 32 in a week or two. The plan is to put around 10 VMs with 2-4 G of configured memory on that system. bhyve doesn't do page deduplication like ESXi does, yet - right?
