I have a Mac Mini late 2012, 16GB ram with 500GB disk, multiple (3) gigabit NICs, and some external USB3.0 drives.
My requirements for guest OS are:
- One Macos High Sierra with Server.app
- One pfSense linux guest (requirements are minuscule. CPU 600MHz, 512MB RAM, and 4GB HDD)
- Maybe a second Linux instance to tool around with - No windows guest VM
My research shows I don't need to use ESXi but it has a lot of features I'd like to leverage, snapshots, Multiple test configurations and etc. Given that nothing else is running in the ESXi environment.
(the goal of knowing how to measure this lets me weigh if I upgrade to an SSD and or even bother to install ESXi)
I'll be using the ESXi6.7
In your experience, how much (CPU/RAM) overhead would the virtualization layer add?
