Why we need machine virtualization
Repurposing a server can require rebuilding the whole operating system. This can take (relatively) a lot of time. 
Virtualizing the machine allows two or more operating systems to share it. (One can be running normally even while another is being built.) 
Also, whole operating system instances can be prebuilt and latent, ready to start running when needed.
