The question is pretty vague, and also sounds suspiciously like a homework question, which is probably why you're not getting answers.
Vserver is not Fedora's--there is a Linux VServer, which is frequently used with RedHat based distributions--you can look at the article on the CentOS wiki, though I think that's dated by now.
To answer the question, it would be debatable whether it simplifies it--you'd be better off writing the developers for their spin on it, assuming that's the answer you definitely want--it means using a special (unsupported) kernel. This is assuming you are talking about the Vserver to which I linked before. If you're talking about Fedora's preferred virtualization method, KVM, it's a different thing.
Please don't take this wrong, but you might want to look at
which has a lot of useful advice about framing questions.
