Matahari really isn't a candidate for a lightweight guest agent for
virtualization because of the heavy dependency chain.  So it's not
really in contention with ovirt guest agent or qemu guest agent.

Matahari will continue to be developed for general systems management
functionality, but it doesn't need to be further considered for this
specific usage.
