Determining the data of the host machine through the virtual means of the site?

Question

JavaScript

Situation: through the browser of the virtual machine we surf the Internet.
Is it possible to determine in some way through the visited site (for example, through java, javascript, ActiveX):

1. the characteristics of a real machine? (exploitation of a vulnerability in a virtual machine that allows access to a real system is not considered. We accept it as an unlikely event)
2. using a virtual machine?

Answer 1

For some reason, I hardly believe that from a virtual machine you can see the characteristics of a real machine.

Answer 2

That's what I originally thought too. But maybe there are some BUT - certain conditions under which this is possible?
