What are the differences between a hypervisor and a paravirtulizer?

Question

Virtualization

What literature on hypervisors and paravirtualizers can you recommend, so that the teapot can understand. And the most important question: why is a hypervisor better than a paravirtulizer (and what is a paravirtulizer)?

Answer 1

The story on the theme "heard a ringing, but does not know where he is."
In short - the difference is approximately between the words "fork" and "cutlery". A hypervisor is any software that manages virtual machines (and there is also an opinion that a hypervisor is also a piece of hardware on which virtual machines run), regardless of the type of virtualization (even containers).
Paravirtualizer - some kind of "soviet" name of the hypervisor involved in paravirtualization (the one where the guest system starts on its own, but requires modification - for example, a specially assembled kernel (as for xen-pv, for example)).

Answer 2

here they write what a paravirtulizer is
here they write what a hypervisor is
Better than it says there, I can’t explain)
