Open Stack

David,
At the datacenter IAAS level, your best option from strictly a cost perspective is to run hyper-v role on windows server datacenter core as your hypervisor and license that.  (Once again way over my head, but this is my understanding)

The guests would be covered under that regardless of the density of (windows) vm's on the node.

If you used the free hyper-v server you would have to license each vm.   I'm not sure how the volume/iaas/datacenter licensing works.

Email your exact questions directly and I'll forward the request internally.

This is a very interesting thread for us :)

How about desktop versions of Windows? 
Is there a volume license that can be used with the IaaS?

I checked with MSFT Licensing, the rep said there is no limit on number of uses of a KMS license key, just an aggregate activation threshold. See further http://technet.microsoft.com/en-us/windows/dd197314.aspx for more details.
