It is in the third posted URL:

A hypervisor provides the virtualization abstraction of the underlying computer system. In full virtualization, a guest operating system runs unmodified on a hypervisor. However, improved performance and efficiency is achieved by having the guest operating system communicate with the hypervisor. By allowing the guest operating system to indicate its intent to the hypervisor, each can cooperate to obtain better performance when running in a virtual machine. This type of communication is referred to as paravirtualization.

Yes. Xen uses this technology too - and we all know that it is fast.

Re: VMware demonstrates para-virtualized Linux

I know what you mean, brazzmonkey. That word "hypervisor" just sounds so made up, but apparently it's been in use since the 60's.

This article may help you - I found it useful, anyway.
