Like I said, I'm not familiar with easyVMX
As as I can see, you download a small prebuilt vmx environment more or less specific for the OS you want to install and then install the guest OS as you normally would into that environment.
Looks interesting. It might work well or it might not. For sure cheaper than VMWare Workstation but likely less easy/customisable.
Why don't you give it a whirl and report back?
