I have several existing x5570 based servers running in a Hyper-VM cluster farm managed by Virtual Machine Manager 2008 R2. I would like to expand the farm, but obviously technology has moved on. I am considering adding
3 more E7-8837 based hosts
or
4 more x5675 based hosts
My question revolves around the VM's and CPU compatibility. Will I be able to add either of these processor types to the existing farm WITHOUT having to enable CPU Compatibility on the vm's in Virtual Machine Manager 2008 R2? I can't seem to find that answer anywhere.
(In case it isn't clear, I'm referring to the "Allow migration to a virtual machine host with a different processor" setting on the properties of the CPU assigned to the vm in Virtual Machine Manager 2008 R2)
Thanks!

That will depend on the VM software that you are running, so in this case you need to contact the VM software developer so they can answer your question.

Microsoft (the virtualization vendor) says to contact Intel since you are the people who maintain information on each processors capabilities. Kind of leaves the customer in a jam when neither vendor wants to verify compatibility. In this case, I agree with them since I need to know what is different between these 3 processors from an instruction set perspective. You wouldn't expect MS to have that information on hand.
Maybe we can do this a different way. Since I do not have either processor yet (trying to determine which I'll buy), can I somehow get the output of CPUID from each of them so I can compare?

If the information that you need is not located on the datasheets of those processors, then you will need to contact a Field Application Engineer (FAE) trough out any of our local Authorized Intel® Distributors, so they can provide you the information that you need.
You can find a list of Authorized Intel® Distributors at:

When contacting them, please tell them to put you in contact with a Field Application Engineer (FAE).
The datasheets for those processors can be found by selecting one of the processors here:
