I do not have any experience with Hyper-V but a quick search turn up "Integration Services" which appear to provide similar functions as VMWare tools, (Drivers on the VM to improve performance.) Are you using the latest version installed on the VM?
Are all of your VM's showing the same activity or just this one? What values are you seeing?
I think that I would start by shutting down application services one by one and see if the problem goes away. That would give you a starting point as to where to look next.
