I've googled this like crazy, but just can't quite find the answer I'm looking for.
What is the big performance difference between a Type 2 hypervisor such as VirtualBox, which runs like software inside another operating system. Compared to a type 1 hypervisor such as ESXi which runs on a server machine, and the virtual machines are accessed remotely on other pc's?
I've used VirtualBox quite a bit, and never used ESXi yet, but I just can't quite wrap my head around how a type 1 hypervisor could work, or perform anywhere near the level of a type 2? I mean, there must be such an incredible amount of data exchanged. I'm imagining all the data from a 1920x1080 display being refreshed 60 times a second, plus all sorts of input and output data, and who knows what else, having to be sent through a little ethernet cord. I mean, even a DVI cord used to connect a monitor to a PC is has something like 18-24 pins, so how can an 8 wire ethernet cord supply all that video data, plus all the other necessary data fast enough to be usable?
