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).
