I've pulled more of my hair out trying to install the 9.8 vSIM on VM Workstation Pro. It is by default setup to use 5.1GB's of RAM, but I've found it locking up and freezing, very soon after coming up, even at the cluster setup questions.
I finally saw Matt Elver's post, https://community.netapp.com/t5/Simulator-Discussions/Upgrading-simulator-from-9-7-to-9-8-fail/m-p/165322 about the upgrade. I tried it, and had immediate success.
So I've setup all three nodes with 8GB's of RAM.
