Update,

I got it working!!
It was way easier then i thought it would be.
Followed the instruction post on the fog wiki

At the end of step 5 when you pick what you want installed, I just did a ctrl+f (or edit find) and searched for vmware, and checked “VMware PVSCSI driver support”. then saved it then went on to setup 6 in the instructions

This might help, doesn’t seem too involved.
