Why bother, when you can run a hypervisor on the machine and allocate as much as you wish? It's not like you need to squeeze every last drop, and if you did, you'd probably be installing netatalk/Services for Macintosh yourself.

Seriously, virtualization and containers isn't just handy, it's also easy to deploy, manage, and secure. (Not terribly relevant, but the sheer ease of it makes it easy.)
