Let's stick to the realm of x86

that's the architecture I know best.
Starting off, generally, when you preform virtualization, your VM
runs (usually) under an OS.
Some vendors extol the virtues of running a hypervisor
on "bare
metal". Of course, all this really means is that they're running
it under a completely proprietary host operating system rather than
on Linux or Windows. Perhaps there is some benefit if the
off-the-shelf host operating system gets in the way of the
hypervisor, but I haven't seen any evidence to suggest that Linux
does. (I don't know enough about the details of the Windows kernel
to comment on that.)

And that's why I say "usually".
