I think he was asking more about a guest install rather than a host. I'd echo the comment Les made and recommend to the OP to 'try both.' Virtual installs and physical installs are a tad different, but virtual has some distinct advantages, especially in terms of quick cloning, snapshotting with rollback capabilities for testing, etc. But virtualization brings with it another layer; and I would go as far as saying that, once you've gotten some experience, and if you have 64-bit hardware at your disposal, that you might want to attempt duplicating your hosted VPS environment completely, on you own 'host' as then you can test with the exact configuration you're using in production. That would mean the same VPS packages, the same 'guest' install options, and the same host OS packages. But before throwing so many new layers in the mix try I'd recommend to the OP to get familiar with it one layer at a time; too many layers at once can be very confusing if you don't know enough to separate the effects of each layer.
