As others have said free versions of all the major Hypervisors are 
available so I can't see what cost there is. Even for the poor it will 
usually save money.

If you already have a server that is not fully loaded and enough 
capacity to run VMS you can virtualize the exiting OS image and add VMS.
There are free tools to let you do this.

If you need to buy a new server, well I can't believe any one is going 
to max out even the cheapest modern server running VMS.  So if you have 
to buy a new server using a Hypervisor allows you to utilize the spare 
capacity.

You can run another OS or two instances of VMS so you have a test 
environment.

You are taking to emulated hardware so your OS can easily be moved to 
another platform.

I used to think like you, but these days, if I was installing almost any 
server it would be with a virtual hypervisor.
