that I buy for binary only hypervisors. But in an open source world I'll
buy this a LOT less as being relevant.

Binary compatibility to Linux is pretty important for applications. Even though Apache is open source, I don't want to recompile it for every new Linux kernel. Fortunately I don't have to, because glibc abstracts the Linux kernel interface. Consider VMI in the same role as glibc -- when the hypervisor changes, VMI maintains compatibility with your pre-existing infrastructure, while letting you have some of the benefits of the new hypervisor. The upgrade and recompile game can quickly end in a stalemate when you have packages with conflicting dependencies (one package requires the old version, and the other package requires the new version).
