On VMware Workstation I used Win 2k8 64bit Expermental template as is.
I pointed the cdrom to the location of the ISA rather than using a burned in cdrom (it loads faster that way)
I gave it a 60 gig harddrive
4 gigs of ram (this box has 6 gigs total, and another 1 gig is for a Virtual Vista)
Two processors and everything else plain vanilla
HyperV can be used and you have to use legacy nic. I’ll see if I can steal a post from Charlie Russel on the HyperV how to.
But that’s the basic vmware workstation setup that I did to run SBS 2008 on a virtual setup.
