Comment Chrome is a virtual box too - NaCl (Score 1) 201
This seems to talk purely about virtual servers, not hardware. Everything above hardware is nothing but programs, even if we call them virtual PCs. They only differ in the level of integration with the rest of the machine and peripheral devices. For example, javascript running in a browser could be considered as much of a virtual pc as Oracle's VirtualBox, with the only difference being the interface with which internal code communicates with the outside. Chrome's native client (NaCl) ability to run native code without any interpretation while still maintain complete isolation from the OS and other processes is the best example of complete virtualization.
