The KVP driver is a different module as far as I can see.  But it really
needs a lot of work, as no one should use the ugly connector interface
for new code.  The closest equivalent is gennetlink, but I'd like to
understand what it's actually supposed to do in practice.

Chris,

I wrote the KVP component of the util driver less than a year ago and 
This code was reviewed on this list before it was accepted. The KVP (Key Value Pair)
functionality supports host based queries on the guest. The data gathering in
the guest is done in user-mode and the kernel component of KVP is used to
communicate with the host. I am using the connector interface to support
communication between the kernel component and the user-mode daemon.
The KVP functionality is needed to integrate with the Microsoft management 
stack on the host.
