Let's stick to the realm of x86 virtualization

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.)
