Measuring Hypervisor Footprints

There have been several interesting posts in the blogosphere about virtualization security and how to measure it. Specifically, the discussions are really about the size of the hypervisor footprint or about the size of patches. But hypervisor footprints from a security perspective are neither of these. The concern when dealing with hypervisor security is about Risk not about the size of the hypervisor or the size of a patch it is purely about the Risks associated with the hypervisor in terms if confidentiality, availability, and integrity.
