>Go read about hardware assisted virtualisation on x86/x86-64.
To further on this excellent and valid point, very cheap virtualisation was available on a lot of other very solid and very productive architectures and has been for decades; it was just x86 finally catching-up late. There are a whole lot of reasons speaking FOR virtualisation and only a few very specific applications where it might be a bad idea. I have no idea what OP up there is all about and against it, they make no sense.
