The main issue you need to be concerned with when getting a virtual server for SEO purposes is do you get a shared or dedicated IP?
Most hosts share IP's among their customers so they can get more profit per server. This may be good for them, but it is not good SEO.
www.GotWebHost.com never shares IP's among our clients, because we understand what "SEO hosting" is all about.
The fact of the matter is that most SEO's do not really require dedicated servers unless they are using a lot of resources.
