I'm checking out VMWare Player as we speak... what else besides the player do i need? it says i need a configuration file? WTF is that? ***scratches head***
The config file tells it such things as whether you want the guest to be networked, NAT'ed, or run strictly locally, whether you want local or SAN storage (I don't know if Player is SAN capable but ESX is) how much memory to give the guest, how much CPU capacity, etc, etc. Pretty slick stuff.
Echo try reading this whole thread..
