VMMs versus Hypervisors

So a HyperVisor doesn't have a full-fledged OS under it. What provides it with, say, file-system support? How does it read VHD files?

I was looking for definitions of hypervisors and paravirtualization a few days ago and came across the following useful reference from IBM:

http://publib.boulder.ibm.com/infocenter/eserver/v1r2/topic/eicay/eicayvservers.htm

I notice you use the terms Type 1 and Type 2 VMM and refer to a Type 1 VMM as a hypervisor. However, IBM use the Terms Type 1 and Type 2 hypervisor. Also, they place Microsoft Virtual Server in the Type 2 Hypervisor category.

Also in the table in the above referenced site, IBM have a trademark symbol next to Hypervisor. I never realised that IBM owned the term.

What are your thoughts?

I have similar problem, VPC image created for Windows 2003 and running on my laptop, which has Windows XP installed.
I did installed patches and various other stuff to solve the "repeated keys" problem in VPC. Also in VPC, CPU usage is always high makes performance very low. I have SQL server 2005 and BizTalk 2006 on VPC.
I also noticed if, I shut down SQL server service and enterprise SSO service, CPU usages comes down from 90% to 8%.
Please help me in this regards..
