Can't do this. Putting vm monitor modules into our main packaging has
caused way too many problems already (vmware, vbox and the like).
Matching our pre-installed vmmon to the userspace application is
extremely difficult, and the incompatibilities for new userspace
application ABI to the vmmon ABI causes even more problems than you are
trying to solve.

Let's not get melodramatic. All virtual machine vendors suffer the same
problem. VMWare has taken a good step toward making this easy for the
user in their new beta versions where the GUI handles the recompilation,
and thus, makes them distro agnostic on how they handle this problem.
Of course we care, but virtual machine vendors (both proprietary and
open source) have a self inflicted kernel+vmmon+virtual-machine ABI to
stick to, and mixing it with kernel ABI matching just doubles the
problems. DKMS (or something similar) is the preferred and desired way
to resolve this if the vm isn't going to handle it itself.
