If you want to go virtual, but can't because it isn't yet supported by Symantec, plan for both. It's looking like I will inherit an old VM box (4 processors x 2 cores = 8 cores) because they have cheaper licensing for VMWare by using fewer processors (2 processors x 4 cores = 8 cores). But originally, my SD7 project plan called for physical systems that could work for SD7 or VMWare. When virtualization is supported for SD7 (hopefully?), SD7 would undergo a Physical-to-Virtual migration to an existing VMWare box, the "old" SD7 retrofitted to VMWare ESX, and then SD7 (now virtualized) moved back over.
